Version History
Thankyou for using Mappy, hopefully you will find it a
useful tool in creating your own games. This software is freely
distributable, and you may use it and the accompanying playback
libraries freely with no licence, the only restriction is that
you are not allowed to charge for this editor or the playback
libraries, or distribute a modified version of this editor
without the author's consent. You may, of course, use the
playback libraries and maps you create as you wish.
What is it? Well, I have tried to make the most
comprehensive and powerful 2D tile map editor about. The idea is
that you make some graphic 'tiles' of a set size (such as
32pixels wide by 32pixels high) with some paint package in such a
way as to be able to put them in a grid so they form a large
area. You can assign properties to these tiles so that maybe a
sprite (a graphic on the screen) can't go over certain tiles, or
maybe goes under one tile, but over another. You can also animate
tiles and lots more besides. If you don't find Mappy suitable for
your needs, or have suggestions for it, please email me about it.
I have also made several playback libraries available that
you can incorporate in your games which make display and
animation of the map easy. These playback libraries are available
from the Mappy site, and include MappyDX (for DirectX SDK C and
C++ programmers and CDX users) and MappyAL (for DJGPP/Allegro programmers).
Please take the time to look at this documentation
If you want to contact me, please email the address shown when
you select 'About' from the 'Help' menu or the address on the
Mappy homepage. The current Homepage for Mappy is: http://www.geocities.com/SiliconValley/Vista/7336/robmpy.htm

Sorry about that, but I don't think it's fair that I get
sued for something I release for free, just remember to keep
backups and you'll be fine. I have never lost any data or files
or had Mappy screw anything up, just be aware that if it does I
can't be held accountable :)
Note: These are the features for Mappy Win32 other platforms
and versions have slight differences in features, but all make
the same FMP files...

relatively lowly 200Mhz K6 I can run my monitor rate of 75fps in
800*600*16 with all layers and parallax, and the playback lib
MappyDX is faster yet
Layers, 4 for each block, 8 in the map including
transparency and depth.
Expansive and useful documentation (surely the best
feature?)
I have not been able to get Mappy to run properly under
Win3.1 and Win32s and as I don't have this setup I can't really
do anything about it, sorry, though it works fine under 95, 98
and NT. You will need your desktop in 15bit colour or higher
(high or true colour, the more colours the better). Double click
Mapwin.exe to start it. You will see Mappy open at the default
640*480, you can resize the windows as you like, also note you
can specify your own size on startup, see Hints
and Tips. If you just want to try out Mappy and aren't doing
anything serious yet, you'll find it pretty easy to use. Select
'Open' from the file menu, or simply press Ctrl+O, you should see
the file test.fmp, double click it and it will be loaded into the
map editor.
You should now see the map in the Map Editor (left)
window, and the still blocks in the Block Editor (right) window.
If you have a high resolution desktop and the tiles look a bit
small, select a 'Zoom' from the MapTools menu. Click the left mouse
button over a block in the Block Editor (right) window, you
should see a black and white rectangle appear round it,
indicating it is the active block. Now move the mouse over to the
Map Editor window and click the left mouse button to place the
block in the map. You can hold the left button down and move the
mouse to 'paint' with the block. Try scrolling
around the map with the cursor (arrow) keys, or using the sliders
at the right and bottom edges of the Map Editor window. You can
undo the last action you made by selecting Undo from the Edit
menu (or simply Ctrl+Z), you can undo your undo by selecting it
again. If you are having trouble seeing where tiles meet, select
Grid from the MapTools menu, blocks in the Block Editor window
will now have an outline, and the block the mouse pointer is over
will be highlighted in the Map Editor window.
One of Mappy's best features are animated blocks, to see
them click the right mouse button in the Block Editor window, you
should see the title of the window change, and any animated
blocks will be displayed, you can select and use them just like
still blocks, you can right click again to get back to the still
blocks. In a new project, there are no animated blocks to start
with, you should switch to the animated blocks window, and select
'New' from the Edit menu. A handy shortcut is to use the ',' and
'.' keys to select
the previous/next block and the 'p' key to select the block the
mouse pointer is currently over in the Map Editor window.
Although I'm not going to cover this in the quickstart, you can
double click the left button on a still or animated block in the
Block Editor window to edit it's properties, try it on both types
to see the options. You can use any of the options in the Edit
menu to manage the blocks, normally you would do this before
drawing the map area, although Mappy does try to be 'smart' in
minimizing unwanted alterations to the map.
Now let's try something a bit more advanced, select Brush
#1 from the Brushes menu (you will see it has a tick, or check
mark next to it when you select it), then the Grab Brush option
from the same menu (Ctrl+B) now position your mouse over the
corner of the area you want to brush in the Map Editor window.
Click the left mouse button and hold it down and move the mouse
to the opposite corner of the area you want to grab, you should
see a 'bounding box' indicating the area. When you have the area
you want selected, release the left mouse button. You can now
paste that brush anywhere you like with the left button (the
brush will not be pasted if part of it would go off the edge of
the map) the top left of the brush will be at the mouse pointer.
Note that any 'block 0' blocks in the brush will be treated as
transparent so you can have non-rectangular brushes. You can also
use brushes for filling, find an area with a number of identical
blocks next to each other (the black areas are good), place the
mouse pointer over the 'starting block' and press the 'f' key,
that area will now be filled with the brush, over and over with
the top left of the brush where the mouse pointer is, try it and
see. Undo the fill with Ctrl+Z, now do the same, but press
Ctrl+F, the area will be filled with random blocks from the
brush.
You can try out the other features as you like (especially
the rather cool Anim Preview from the MapTools menu), when you
decide to do a map you want to use, please read the rest of this
documentation, it contains many more details such as design
considerations, layers and transparency. I'd really like to hear
what you thought of Mappy, please email me your comments, good or
bad, Robin Burrows
I have designed Mappy to hopefully be expandable,
produce small mapfiles with lots of features, and most
importantly be fast and easy to playback. The FMP format (how the
maps are stored) is a 'chunk' based format which allows all the
information for the map (graphics, array, anims, block data etc)
to be stored in a single file, you can also add your own chunks
to this file if you want, more details in FMP
file format.The playback libraries
then provide functions to load and play the map within your game.
The map editor comes in several versions, this
documentation is concerned with the Win32 version. To make a map
from scratch, you will need to make, or get some 'tile graphics'
(if you don't know what some of these terms mean, see the glossary) in uncompressed BMP format and
import them into a map (see next section). It is important to be
aware of the hierarchy of the objects within Mappy, you have the
top level which is the Map Array
(this is shown in the Map Editor window), the elements in that
are short int offsets to either Block
Structures if they are positive, or Anim
Structures if they are negative, Anim
Structures contain offsets to Block
Structures, Block Structures
have 4 offsets to the Graphics Blocks
(amongst other things).
MapArray ------> Block Structures --------> Graphics Blocks
......\............................/
........\Anim Structures/
That's about as much as you need to know if you don't intend adding your own objects, linked lists etc and are going to use the playback libraries.
Before spending hours on a huge project it is important
to think about various aspects of it, what size are the tiles
going to be? What resolution(s) and colour depth(s) is the game
going to run in? What sort of view is it going to have (overhead,
side, oblique, isometric)? How are the other game objects going
to interact with the map? If you haven't done many tile based
games before, it may be best to do a very simple pacman or
shootemup project, just to get the hang of things, design is everything.
Tile size is one of the most important things to consider,
currently there is no way from the editor to pick a different
size than the one you choose from 'New Map' (though you can
resize the map array to make it bigger or smaller). Colour depth
also cannot be changed once set, though you could process the FMP
file yourself to change tilesize and depth, you could also email
me to request it for a future Mappy version. I would recommend
that the width of the tile is a multiple of 4 (better memory
alignment), try 16pixels wide by 16pixels high for low res games
(320*240, 320*200) or 32*32pixels for 640*480 screen resolutions.
Remember that computers are advancing all the time, try to
support multiple colour depths and resolutions (if you think it's
worth it), also consider doing your map in 24bit colour even if
you are aiming for a 16bit screen, with an option to select any
high colour depth, MappyDX supports colour conversion, check the
docs for the other libs, of course, 24bit colour uses more disk
space than 16bit. If you are aiming for a lowspec machine with a
low resolution (such as VGA 320*200) use the Zoom option to get a
better idea of the graphic size in Mappy, also if you know you
aren't going to be able to access the video acceleration on the
videocard (for example using VESA under DOS) bear in mind there
will be a huge performance hit (the Anim Preview in MappyWin32
uses DirectDraw blitter acceleration found on almost all graphic
cards)...
The FMP file is ready to use from the first time you save
it, so it makes sense to develop your game code at the same time
as the map so you can see how things work and how fast they go,
also remember to adjust the preview setup in MappyWin32 to the
screen res. you are going to use...
When making your graphics for tiles, use a picturesize
that is a multiple of the tilesize, for example 32*32 and 16*16
tiles fit nicely on a 640*480 or 320*240 picture. To import them
into Mappy they will need to be lined up in a grid (export the
tiles from the example map as a BMP and load them into a paint
package to see how to do it, completely black tiles are ignored).
This has the standard file features such as Open (open
a .FMP mapfile for editing), Save (saves current .FMP file under
it's current name, if it hasn't been named this is the same as
Save As), Save As (requests a name to save the map, .FMP will be
added if you don't type it in then saves it), Exit (quits Mappy,
same as clicking the cross gadget in the window titlebar, you
will be warned if you have modified a map but not saved it), and
some Mappy specfic ones, which are:
New Map. Brings up the new map dialogue where you choose
settings for the new map, you should have carefully decided on
the values you enter here (see Design
Considerations). Either the default values will be shown, or
the values for the currently loaded map (currently loaded map
will be cleared from memory if you OK from New Map), you can
modify these values to any legal value, the first number (tile
width) should be a multiple of 4pixels (8bit) or 2pixels(other
depths). You can change the colour depth by clicking the
displayed one and selecting a new one from the dropdown list.
Note: Your Windows desktop doesn't need to be in, or support,
that depth, your Windows desktop does need to be in high or true
colour though (yes, even for 8bit maps :). The only values that
can currently be changed after creating the map are the map width
and height via Resize. When you 'OK' you will be given a map
filled with one block (shown in the Block Editor 'still' window)
this is a special block, you can edit it's properties (by double
clicking) but not give it any graphics or delete or move it from
the first position. Now may be a good time to check 'Map
Information' in MapTools to see how much space is being taken up.
Import. This is used to get your tile graphics into your
map, at the moment it only supports uncompressed BMP files, if
you have an 8bit map you can only import 8bit BMP files (and the
colour palette will be taken from the most recently imported
one), in other depths you can import both 8 and 24bit
uncompressed BMP files. There are plenty of conversion utilities
out there if you are using a different picture format. You can
import more than one BMP file, when you have selected the BMP
file to import, you will get the question: "Make all
imported graphics into NEW block structures?" If you answer
'Yes' new blocks will be created in the Block Editor 'still'
window that have each new graphic tile as the BG (see Block
Structures in the glossary), if you
answer 'No' you will be asked: "Replace existing
graphics?". Answering 'Yes' to that will write over the
current map graphics (except the special first one), the most
common reason to do that is when you have exported the existing
graphics and modified them, and want to update the map graphics.
If you say 'No' to replacing existing graphics the new ones will
be added to the map, but won't be visible until you incorporate
them into a Block Structure.
You can also import Map Array layers (click the 'Files
of type' arrow in the file requestor). These MUST have been
previously exported from this map, and you must not have altered
the blocks.
Export. You can export individual parts of the map as
separate files, which you may need for various reasons, though
the playback libs use the FMP files. There are five checkboxes,
click them to indicate you want to export that particular item
(they will be given the same name and be put in the same
directory as the map file, so if your map was called test.fmp,
the colour map would be exported as test.cma any file with that name will be overwritten!).
The colour map is exported as a 768 byte file containing
256*3byte values of 0xRRGGBB, this is the same as the CMAP chunk
of the FMP file. The Anim and Block data is exported as a long
int offset to the split between the anim and block structures
then the anim info, then the block structures. The map array is
simply an array of short ints mapwidth wide by mapheight high, so
a 100*100 map would produce a 20000byte .MAR. Block Graphics
(.GFX) are all the raw blockgraphics one after the other, so
that's blockwidth*(blockdepth/8)*blockheight*numblockgfx.Block
Graphics (.BMP) is a standard uncompressed BMP file in 8bit (if
the mapdepth is 8bit) or 24bit for any other depth, you can
specify how many blocks per row and this will affect the shape of
the BMP file, this is useful for modifying the graphics, then
re-importing them.
This will show how the map is layed out, and allow you
to edit that layout. Simply select a block, anim, or brush and
paint with it by clicking the left mouse button on the square
where you want to place the tile, you can alter more than one
square by holding down the left mouse button and moving the
mouse. You can fill an area of blocks with either a still
block, anim block or brush (depending on what is currently
selected as your drawing item) by pressing the 'f' key (make sure
caps lock isn't on) when the mouse button is over the block you
want to start the fill with. You can also fill randomly from a
brush with Ctrl+F, you can weight blocks by having more than one
in a brush (try and see, you can undo a fill with Undo, Ctrl+Z).
Another handy shortcut is to press the 'p' key while the mouse
pointer is over the block you want to pick in the Map Editor
window, this will now be your current block/anim. You can select
the next/previous block/anim by pressing the ',' and '.' keys.
You can move the area seen in the Map Editor window by
either using the scrollbars on the right and bottom edges of that
window, or by pressing the arrow (cursor) keys, hold them down to
scroll along. When you get to the right or bottom edges of the
map you will see a grey area which cannot be modified.
Information about the block under the mouse pointer is
given in the window title bar, T=1 means transparency is set
for that block.
This shows all the still and animated blocks that have
been created, you can toggle between the still and animated
screens by right clicking the mouse over the Block Editor window.
To select a block or anim, left click the mouse button on it, you
can now draw with it in the Map Editor window. Remember to turn
the grid on (Ctrl+G) if you have trouble telling where the block
boundaries are. You can add a new block/anim, cut copy and paste
(all in the Edit menu), new and paste put the block after the
currently selected one. Note that cutting a block will remove any
references to it from the map array (they will be replaced with a
reference to block 0), and pasting it will not put them back, so
it's usually best not to cut blocks you are using in the map
array. Also note that cutting a block does not remove the
graphics it was using. Undo does not work when editing the Block
Editor.
You can see more blocks/anims by scrolling up and down
with the scrollbar on the right of the Block Editor window.
To edit a block structure, double click it in the Block
Editor indow.Depending on whether it is a still or animated
block, you will be shown a dialogue giving details about it and
allowing you to change it.
Editing Properties of a Still Block.You will be shown the
block you double clicked, along with it's properties. The numeric
information is not used by Mappy and is entirely for your own
use, as are the four collision detection bits. Of the Other bits,
the top left of them indicates whether transparency is taken into
account (you will nearly always check that in block 0 if you plan
to use transparency, as well as any blocks that have a
transparent colour in them). In the bottom left, you will see the
four layers of graphics that make up the block's appearance,
simply click them to pick a new graphic, BG is used as the back
layer, you will probably only want to use the first FG layer,
this allows you to draw the map in layers in the playback
libraries, sandwiching sprites between them to give depth. You
can go to the next/previous block by clicking the arrows next to
the OK button.
Editing Properties of an Animated Block. Double clicking
an animated block in the Block Editor window brings up this
dialogue. Animated blocks are made up of a sequence of still
blocks, you do not pick graphics when you edit them, but still
block structures. The reference block is how the anim appears
when it is not animating (such as in the Block and Map Editor
windows), click it to change. Below that is the sequence of still
blocks, there is a black and white 'C' shape indicating where
frames will be inserted and deleted, simply click where you want
to insert or cut, then click the Insert or Cut buttons. Clicking
Insert will take you to another dialogue where you can pick up to
30 frames to insert (you can have more than 30 frames in an
animation, just click insert again). When you OK, you are
returned and the new frames will be shown, with the edit point
'C' cursor at the end of the new frames. The Delay is the number
of calls to UpdateAnims before the next frame is used, so the
higher it is the slower it will animate, the actual speed is
determined by how often you call UpdateAnims (a playback library
function), you can get a rough idea with Anim Preview from the
MapTools menu. To the right of Delay is the style of animation,
click to change, LOOPF continually loops forward, ONCE only plays
the anim once (this is so your game can trigger an event), PP
pingpongs between the start and end frame via the middle ones.
This contains New, Cut, Copy and Paste for use with the
blocks in the Block Editor window (see
Block Editor for how those work).
Resize, which allows
you to resize the map array of all layers. Before resizing it is
advisable to save the map as you can't Undo it (though you can
resize back to the original size). The Resize dialogue shows 9
buttons on the right which show which edges rows and columns will
be removed/added to, be sure that the Map Centering text at the
top shows the correct number (the default is 5, rows and columns
will be added/removed equally from all sides to make the new size
map). If you select centering as '1' (top left), columns will be
added/removed from the right and bottom edges. Select the new
size by entering the numbers in the width and height boxes, then
OK to resize, or Cancel to keep the old size.
Undo is very useful, but doesn't work on everything, it
will undo everything since the last left mouse click in the Map
Editor window (including the area you can't see), especially
useful for undoing Fill or when you 'paint' by holding the
mousebutton down.
There are all sorts of goodies in here, the first is
Map Information. This allows you to put your name and a 3 line
description of the map, the length of each line is limited to 68
characters, this information is saved in the FMP file. Below is
how much memory each type of object is using in the map along
with the total space used for those objects.
There are then two options for previewing the map in
DirectX, you must have DirectX3 or greater installed to use this.
First, choose Preview Setup. Select the screenmode you want to
use from the list, these are reported by DirectX so only valid
ones are shown, it defaults to 640*480 *bpp ?hz which is
640pixels wide, 480 high, bpp is the depth of the map and the
default refresh rate for that mode, pick whichever you like,
preferably the one your game is going to run in, beware that
running excessively high resolution modes on monitors not
designed for that mode may damage the monitor. Check the boxes
below for which block layers are drawn (the default is background
(BG) with the first foreground layer). Below are the transparency
options, check the box to enable transparency on the preview, if
you want a parallax layer (very handy for checking proper
transparency) enter the number of the GRAPHIC (this may not be
the same as the block number, 0 will be plain black or colour 0,
you can see what the graphic numbers are by editing a still
block, clicking on the BG image and looking at the list) this
will be repeated over and over in any transparent regions
(remember to check the transparency box, the top left box of
Other in the Block properties editor) and move at half the speed
of the other layers creating a rather lovely effect. The next two
boxes you only need to fill in the one which relates to the
DirectX depth you are using. 8bit is simple enough, that's the
colour index that is drawn as transparent, for other depths a
24bit RGB value is entered, this will be translated to the depth
you are using and defaults to the value in the .ini file.
There is one small 'feature' here, if you have a colour like
FF00FF as transparent (R=255, G=0, B=255) and you are showing a
16bit map on a 24 or 32bit screen you will need to modify it to only
5bits (F800F8). When you have OK'd the setup, it will remain in
effect until you change it or exit Mappy, and be used when you
select Anim Preview (DirectX) from the menu, this allows you to
scroll around the map (starting at the point where the Map Editor
window is currently viewing) and see the animated blocks, er,
animating as well as the transparency. There is also a box
specifying the logic rate, leave this at 0 if you want the logic
to match the monitor refresh rate, or specify your own. If you are
making a game you usually can't rely on the refresh rate of the
monitor to regulate speed as it varies (so speed will vary on
different machines). Most games update internally at a set rate
(try 100fps) which unfortunately leads to jerkier movement but
at least the speed is the same on all machines.
Range Edit Blocks allows you to selectively adjust a set
range of block structures. This is particularly useful for
making blocks foreground/transparency blocks. It is simple to
use, type the numbers for the start and end of the range of blocks
you want to alter, then adjust ONLY the things you want to change.
If any of the checkboxes are greyed out, or the user fields are
completely blank the information in each block will be left
unaltered. For more information on these fields, see
Block Editor.
The Remove unwanted options are handy when you have
completed a map and want to reduce it's size. Make sure you have
a backup! If you select remove anims, any anims that aren't used
in the map will be removed, this probably won't save much space
on its own, but when you remove graphics you could save a lot
more, be careful, if you have made an anim sequence that is
inserted into the map in realtime by your game, it will still be
deleted if it is not in the map. Remove blocks removes any block
structures not used by the map array or anim sequences. Remove
graphics removes any raw graphics not used by block structures,
this will make the biggest saving if you do these processes in
the order just described. To check these savings, view Map
Information before and after doing this.
Grid and Zoom have already been described in other
sections. When Grid is checked, blocks in the Block Editor window
have an edge round them, and the block under the mouse pointer is
highlighted in the Map Editor window. Zoom shows things at normal
size when Zoom x 1, twice normal at Zoom x 2, and four times
normal size at Zoom x 4.
Often you will have 'objects' that consist of several
blocks, maybe a house or road or something, there is an easy way
to put these in. First, put the blocks in the Map Editor as they
are supposed to be layed out, then select a brush from the
Brushes menu (it will then have a checkmark next to it), and
select Grab Brush or press Ctrl+B, move the mouse pointer over
one corner of the object you want to pick up as a brush, then
hold down the left mouse button and move the mouse pointer to the
opposite corner, you will see a bounding box as you do this.
Release the left mouse button to finish picking the brush. Now
you will be able to paste the whole object anywhere on the map
with a single click, the block the mouse pointer is over will be
the top left block of the brush you are pasting. You can reselect
the brush at any time by selecting it from the Brushes menu, they
are also saved with the map so you can use them when you load it
next time (but be aware that it may not be on the same number,
blank brushes aren't saved, and when brushes are loaded they are
put in the first free number, if you save a file with only Brush
#6, it will be loaded as Brush #1). You can Fill with a brush as
well, either tiling, or randomly, see Map Editor
Window. If you want to save a bit of space (and it will be a
very small amount) choose the Destroy All Brushes option.
Grab brush from block sequence allows you to make a brush
from consecutive block structures without having to get them
from the map.
Disabling the brush transparency means that block 0 parts
of the brush will overwrite when pasted rather than not
affecting the map.
There are two different layer systems in Mappy, one is
Block Layers, which are the four layers associated with Block
Structures, the other is Map Layers, which is what this menu
manipulates. Map Layers are identical in size and shape to the
numbers you specified in New Map's map width and map height. The
idea is you can use a layer for games objects (like pickup items)
or perhaps changes in a level when a lever is pulled in the game.
The options in this menu are fairly self explanatory. If you just
want to do a load of levels for a game with the same graphics and
blocks, you can export the map array (the current layer) and this
will be much smaller than a whole .FMP file.
Note you can export and import layers as .MAR files, but
the map you are working on MUST have identical blocks and be the
same size. This is handy if you are doing a 100 level game as
Mappy only handles 8 layers internally.
The onion skin option allows you to see transparently
through a layer to one other selected layer. It's best to keep this
feature off if you aren't using it. The current layer (ie the one
which has the tick next to it in the layers menu) is the top
layer which will be the one altered. The background layer is
selectable in the Onion Skin dialogue and will be shown behind
the current layer, you can optionally make this appear darker so
the current layer stands out more. The background layer is drawn
as a guide and will not be altered when you are editing the
current layer. Remember to switch it off when you've finished,
and selecting a layer that doesn't exist for the background is
not advisable :) Loading a map will switch off onion skin.
A large part of Mappy are the playback libraries, these allow you to easily load, manipulate, display, animate and scroll maps help in .FMP files with a few simple function calls. You can get these from the Mappy Homepage, all source is supplied so you can modify them as you like. At the time of writing, there are MappyDX, for C++ compilers with the DirectX SDK, this editor uses a modified version for its Anim Preview, and MappyAL (older versions were called MappyPB). You do not have to use these libraries, you could write your own, but they are very convenient, and MappyDX is pretty fast, too.
The playback libraries are also an excellent way to add more abilities to the editor. For example, you could build a sprite editor onto them for your game.
The first 12 bytes are as follows:
4bytes ASCII = 'FORM'
long int = size of file less header (which is filesize-8)
4bytes ASCII = 'FMAP'
NOTE: The chunk size long ints like the one above are stored in 'Motorola'
format, NOT Intel. You will have to byteswap to get the correct value, ie:
Bytes 1,2,3,4 need to become 4,3,2,1.
The chunks in the file follow on one after the other, and consist of an 8byte
header, and the information specific to that chunk. See how the playback source reads
in the information. The chunks can be in any order, and some chunks may not
be used in a particular file.
Chunk header:
4bytes ASCII = ChunkID (example: 'MPHD')
long int = size of chunk data less header
These are the chunks as of V1.1:
ATHR - Up to 4 ASCII strings of author information, separated by 0 values,
always an even size.
MPHD - Map header, see struct in mappy.c
EDHD - Editor information, see struct in mappy.c
CMAP - Colour palette for 8bit maps, red byte, green byte, blue byte for
however many colours are needed (so usually 256*3 bytes).
BKDT - Block data. Contains BLKSTR structures for however many block
structures were made.
ANDT - Animation data. Contains ANISTR structures for however many
animation structures were made, and also animation data.
BGFX - The raw graphics in whatever format the map is in. Examples: 8bit:
mapwidth*mapheight bytes per block, in forward format *numblocks
16bit: mapwidth*mapheight*2 bytes per block, each word contains
5 bits red, 6 bits green, 5 bits blue.
BODY - An array of short ints containing positive offsets into BKDT, and
negative offsets into ANDT.
LYR? - Where ? is an ASCII number form 1 to 7. These are the same size and
format as BODY, and allow object layers to be used.
You can add your own chunks to a map file, if you load it into mappy,
when you save it, those additional chunks will be saved in the file, but
not necessarily in the same place as before.
You import more graphics, but the colours change and
appear wrong in 8bit. This is due to using different colour
palettes.
You have a high/true colour map, but the transparency colour
isn't transparent. Change the transred, green, and blue values in
the MAPWIN.INI file with notepad to the correct values.
Mappy appears to be working, but no graphics appear
anywhere. I noticed this on Win3.1 with Win32s, don't know why,
if it happens to you email me about it.
Something appears to be wrong with the FMP file you made.
email it to me and I'll take a look.
Transparency doesn't seem to work in the Anim Preview.
Make sure you have the transparency box checked and the correct
index/colour value is shown, also make sure blocks with
transparent colours have the topleft box of the Other boxes
checked under Block Properties.
The anim preview seems jerky/slow. This could be due to
a number of things, poor DirectX drivers for your card, some
windows background application hogging your CPU time or just
trying to do too much. The preview is just that, it's to give
a rough idea of how the map will look. It is worth noting that
the example map, test.fmp, uses 16*16 blocks which are fairly
inefficient for 640*480 or higher resolutions, 32*32 block
maps should give much better results in 640*480.
The map editor always starts in 640*480 and it's a pain to
resize the windows every time. See the following hints and tips
section.
You can't use the exported files in the playback libs,
only the FMP ones, if you want to use exported components you'll
have to write some additional functions.
The colours look all wrong in the Anim Preview. Try not to
display high colour maps on an 8bit screen, you can do it in the
playback libs, but no palette is set in Anim Preview.
Edit the file called MAPWIN.INI that's in the same
directory as Mappy with NotePad. Change the numbers to suit. The
transred etc are 0-255 and are the colour used for transparent
you can change these to any legal value. grid should be 0 for off
and 1 for on, zoom should be 1,2 or 4. width and height are the
starting dimensions of MappyWin32.
Don't have absolutely huge maps, a 1000*1000 block map
with tiles of 32*32 pixels is stupidly big, and uses 2Mb of
memory for each Map Layer, plus it will take forever for you to
make it :)
Please read the documentation, see how big it is? It's not
all waffle. In particular read the Design
Considerations part.
Please let me know about your projects you are making with
Mappy, I'm interested to see how it is used.
Hmmm, need some more tips really, want to add some?
Anim Structure a 16 byte structure and
associated list of frames (Block Structure offsets) of unknown
length
Block I have tried to make 'block' mean
the block structures for this documentation
Block Editor The window that allows you
to select and edit both still and animated blocks. Right clicking
the mouse on it toggles between still/animated
Block Structure a 32 bytes structure
that acts as information about a particular block, it is
referenced by the Map Array and Anim Structures, and in turn
references the raw Tile Graphics
BMP Standard Windows graphic file format,
MappyWin32 only imports and exports 8bit and 24bit uncompressed
versions (Other colour depths are imported/exported as 24bit)
currently
FMP Flexible MaP format, a collection of
all the information needed to render and animate a map for a
game.
Graphics Blocks See 'Tile'
Map Array an array of short int (16bit)
values that reference Block Structures (when positive) and
Anim Structures (when negative). There can be up to 8 layers of
this array by using the Map Layers
Map Editor The window where you fill in
the map array using the various tools provided
Map Layers There can be up to 8 layers of
the map array for objects, ingame changes, etc. Normally you
would only have 1 or 2 layers. These can be selected and changed
in the Playback Libraries
Mappy A 2D tile map editor with lots of
features, this is the Win32 version but there is also a DOS and
WinAllegro version
Playback Library these are available
separately for free at the Mappy homepage, there are several
versions for different platforms, they provide an easy way to
access the map in your game
Tile I have tried to make 'tile' mean the
raw graphics the block structures use for this documentation
Tile Graphics All the graphics
