4.2.2.3 Value Commands

A value command has some value associated with it. Typing the command without arguments will show the current value. Just type the value after the command to change it. Using a `++' or `--' operator before the value will increase or decrease the value with the given amount. Example:

The following value commands are available:

db_maxpol
Set/get the maximum number of polygons that is drawn every frame. Normally this is set to a very high number so that this maximum is never reached (2000000000 polygons every frame should suit everones need for the near future :-) You can reduce this number for debugging purposes. In combination with `fclear' and binding keys to `db_maxpol ++1' and `db_maxpol --1' you can get the effect of drawing one polygon at a time.

db_procpol
Set/get the maximum number of polygons that is considered by the culling routines every frame. Normally this is set to a very high number so that this maximum is never reached (2000000000 polygons every frame should suit everones need for the near future :-) You can reduce this number for debugging purposes.

db_octree
Set/get the level of the octree to show on screen. This is useful to see where octree nodes are. If 0 then nothing will be shown (default). If 1 then the root level will be shown. And so on. If -1 is given then all leaves will be shown.

gamma
Control the gamma value of the display. A gamma of 1.00 is neutral. 2.00 (for example) is lighter and 0.5 is darker. Press g or SHF-g to experiment with this value at render time. This command corresponds with the -gamma commandline option and with the GAMMA configuration option.

fov
Control the FOV (Field Of Vision) of the display. By default this is equal to the height (in pixels) of the current display. Press f or SHF-f to experiment with this value at render time. This command corresponds with the -fov commandline option and with the FOV configuration option.

fovangle
Control the FOV (Field Of Vision) of the display in angles (degrees).

cosfact
Control the cosinus factor (default 0) used for lighting. For details, See section 3.2.3 Engine Configuration.

p_alpha
Change the alpha transparency for a selected portal. You can select a portal by clicking on it (only if it already has alpha transparency) or else by using the `hi' command. Legal values for p_alpha are between 0 and 100.

snd_volume
Change the master volume. Value between 0 and 1.

lod
Change the global LOD setting for sprite. 1 is full detail, 0 is no detail at all (i.e. you will not see the sprite). -1 is disabled. Any value between 0 and 1 is legal. Default is 1.
