- Filename : DMS013.com

- Title : Doom Mouse Spinner (DMS) v0.12 beta
-
- Filename : DMS.COM
- Authors : Tom Klok and Dave 'Zoid' Kirsch
- Email Address : a344@mindlink.bc.ca
-
- Description : Ever had the problem of a monster or
- deathmatch opponent sneaking up behind
- you? Ever needed to turn around *now*?
- With DMS, you can rotate your player
- 180 degrees with a click of the mouse!
-
- Release note : This is a *BETA* release. DMS has been
- tested with Logitech 3-button and
- Microsoft 2-button mice. It should work
- with others without problems. I don't
- know what it would do with a CyberMan.
-
- Release note for DMS v0.13
- : Modified by Lincoln Yeoh so you can use a
- user definable key on the keyboard to flip!
- And added -n for people who don't want to use
- the mouse buttons to flip.
-
- Seems to work. If it doesn't. Tough! Go fix it.
-
- Construction : TASM 3.1, TLINK 5.1

- ================================================================

-
- What it is
- ~~~~~~~~~~
-
- DMS is a tiny TSR (443 bytes resident) that intercepts Doom's
- calls to the mouse driver. By clicking the mouse buttons that you
- define, it will instantly turn you 180 degrees -- facing the exact
- opposite direction. Cranking up your mouse driver sensitivity can
- allow you to do the same, but then your accuracy may fall off.
- With this you don't have to make that compromise.
-
- It supports mouse "chords". For example, if you have a 2-button
- mouse you can set it up to spin you only when you press the left and
- right mouse button at the same time. 3-button mice permit even more
- combinations. I prefer the Middle+Right button chord on my Logitech.
-
- LY> I prefer to flip with the keyboard, and leave the mouse buttons
- for other stuff. That explains this patch :-). This makes it easier
- to run forward, flip, run backward facing opponent, aim, fire, flip
- back again to see where you're going. Also convenient if you back into
- a door- flip, press spacebar..
-
- Does it work for Deathmatch?
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- Sure, why not? It shouldn't cause consistency failure. Some
- might consider it cheating, though.
-
- LY> I think Heretic has this function built in. And I think adding
- the keyboard support makes it a bit more fair now...
- Mouse AND Keyboard is still better!
-
- How it works
- ~~~~~~~~~~~~
-
- Doom uses two standard Mouse API services:
-
- function AX=0003h - mouse button status
- function AX=000Bh - mouse delta mickey counts
-
- A 'mickey' is the smallest unit of mouse movement... sort of like
- a pixel on the screen. Every time Doom requests the new delta mickey
- counts, the mouse driver returns the number of mickeys (X and Y,
- positive and negative) the mouse has moved since the last request.
-
- DMS hooks interrupt 33h, the mouse driver interrupt, and watches
- for those two function requests. Whenever Doom asks for the latest
- button status, DMS passes the request on to the mouse driver and then
- checks to see if the special button(s) have been pressed. If they
- have, it masks them out (tells Doom they never happened) and adds 180
- degrees to the X-axis mickeys the next time Doom asks for them.
- DMS 0.13 does that too, and also checks the keyboard- in al,060h
-
- DMS was written in assembly language for small size. Source code
- is included.
-
-
- How to install it
- ~~~~~~~~~~~~~~~~~
-
- Put DMS013.COM in your Doom directory, or some other directory in your
- DOS path. Simply type 'DMS013' to load it. Be sure you load it AFTER your
- mouse driver, not before, or it won't work. <-- Important!
-
- 'dms -?' or 'dms -h' will display some simple usage help. To
- configure your own button preferences, run DMS with a parameter
- indicating which buttons you want. The default is the right mouse
- button. For example, if you prefer the Left+Right buttons to spin
- you, enter 'dms -lr'. Since I like Middle and Right, I use 'dms -mr'.
-
- You can change your button definitions by running DMS again. It
- will detect that it is already loaded and just update the buttons.
-
- DMS may be loaded into conventional memory, or high memory (UMB's).
- There really isn't any point in loading it high, however, as Doom doesn't
- need much conventional memory and DMS only consumes 384 bytes resident.
-
- Make sure you maximize the mouse sensitivity setting in Doom.
- Anything less than full sensitivity will mean you'll turn less than 180
- degrees.
-
- ENSURE that you have set your controller type to Keyboard and Mouse
- in your DOOM config setup. Even if you are just using the keyboard
- you need the mouse driver and mouse enabled under DOOM for it to work!
- It should work with controller type set to just plain Mouse...
- But that's a weird thing to do!
-
-
- How to uninstall it
- ~~~~~~~~~~~~~~~~~~~
-
- DMS doesn't include software to release itself. Sorry. Go
- download the MARK/RELEASE tools, or just reboot after you're done.

-
- I did try to email Tom and Dave a copy, but their email addresses don't seem
- to work anymore. Anyone know their email addresses?
-
- Thanks to you two anyway. Nice code - finally some PC code that even I can
- decipher!
-
- Thinking of adding auxiliary keys/button for forward and backwards. Nah,
- DOOM isn't a flight simulator!! :-).
-
- Typing DMS013 by itself doesn't seem to select right button by default.
- Can't be bothered to fix that!
