4.2.1 Keyboard Interface

To navigate through a map in the Watlktest application, use these keys:

b
Turn camera the other way around (by 180 degrees).

SHIFT
Makes the following movement commands faster.

CTRL
Makes the following movement commands very slow (for debugging).

UP, DOWN
Move forward or backward.

LEFT, RIGHT
Turn left or right.

ALT-UP, ALT-DOWN
Move up or down.

ALT-LEFT, ALT-RIGHT
Strafe left or right.

PAGE-UP, PAGE-DOWN
Rotate upwards or downwards.

3
Change mode of movement. Default is like most 3D games do (Quake-like). If you press this then movement will be fully 3D (Descent-like). This affects the left and right arrow keys only.

\
Enable freelook mode (press once to enable, press again to disable).

a
Activate a trigger.

SPACE
Fire a missile (a moving sprite and a dynamic light).

l
Toggle lighting (default on).

e
Toggle edges on/off (default off). This is useful for debugging map files. When edges are on you will also see where all the lights are. Clicking on a light will select it (useful for the next key).

SHIFT-e
Toggle frustum viewing on/off (default off). This is useful for debugging the engine. With this option you see the view frustum around the selected light (see the e key above). The white outlines are the shapes where the light may hit the polygon (ignoring radius of the light). The red lines connect the vertices of every outline with the center of the light.

c
Load coordinates from the `coord' file and jump camera to that location.

SHIFT-c
Save current coordinates to the `coord' file.

ALT-c
Show where we are (current sector and coordinates). Output is sent to the file `debug.txt'.

CTRL-c
Toggle display of coordinates while we are running.

q
Quit program.

t
Toggle texture mapping or flat drawing.

SHIFT-t
Enable mipmapping. Three possible states:
`on'
Mipmapping is used according to the distance (default).

`off'
Mipmapping is never used.

`always'
Mipmapping is always used.

ALT-t
Toggle texel filtering (default off). This is an experimental feature which will slow down the engine considerably and also introduces some artifacts on the borders of polygons.

CTRL-t
Turn on/off the display of things (same as `things' command). Default is on.

i
Dump information about the texture cache.

r
Clear the texture cache.

p
Do a performance test on the current location.

SHIFT-p
Toggle perfect texture mapping on/off (default off).

ALT-p
Switch between `smart', `step16', and `step32' scanline interpolation modes. For more info on the `inter' command, 4.2.2 The Console.

m
Toggle `map' mode.

ALT-a
Make a screenshot in PCX format. This currently only seems to work in the DJGPP port.

g
Increase gamma level of display.

SHIFT-g
Decrease gamma level of display.

f
Increase FOV value.

SHIFT-f
Decrease FOV value.

ALT-f
Toggle FPS dipslay.

TAB
Toggle input console. For a list of commands, See section 4.2.2 The Console.

1
Experimental: create a new pulsating dynamic light at your location.

SHIFT-1
Delete the last created dynamic light.

ALT-1
Delete all dynamic lights.

2
Broken.

SHIFT-2
Broken.

F1
(X version only) Used when simulating a 15/16-bit display on an 8-bit display (-depth option). This will compute an optimal palette for the current frame.

F2
(X version only) Used when simulating a 15/16-bit display on an 8-bit display (-depth option). This will compute a greyscale palette and use that instead of the standard 3:3:2 truecolor palette.

F3
(X version only) Restore the standard 3:3:2 palette used for simulating 15/16-bit on an 8-bit display.

d
Assigned to `debug0 toggle'.

SHIFT-d
Assigned to `debug1'.

*
Enable/disable collision detection.
