16 float(string s) checkextension = #99;
18 //check if (cvar("pr_checkextension")) before calling this, this is the only
19 //guaranteed extension to be present in the extension system, it allows you
20 //to check if an extension is available, by name, to check for an extension

30 //darkplaces implementation: LordHavoc
32 //indicates the engine supports .wal textures for filenames in the textures/ directory
33 //(note: DarkPlaces has supported this since 2001 or 2002, but did not advertise it as an extension, then I noticed Betwix was advertising it and added the extension accordingly)
37 //darkplaces implementation: LordHavoc
41 //true if the player is currently chatting (in messagemode, menus or console)
45 //darkplaces implementation: LordHavoc
48 //client console commands:
52 //made +use and -use commands work, they now control the .buttonuse field (.button1 was used by many mods for other purposes).
55 //idea: Nehahra, LordHavoc
56 //darkplaces implementation: LordHavoc
57 //client console commands:
58 //"loadsky" (parameters: "basename", example: "mtnsun_" would load "mtnsun_up.tga" and "mtnsun_rt.tga" and similar names, use "" to revert to quake sky, note: this is the same as Quake2 skybox naming)
60 //sets global skybox for the map for this client (can be stuffed to a client by QC), does not hurt much to repeatedly execute this command, please don't use this in mods if it can be avoided (only if changing skybox is REALLY needed, otherwise please use DP_GFX_SKYBOX).
64 //darkplaces implementation: LordHavoc
66 //indicates this engine supports the "set" console command which creates or sets a non-archived cvar (not saved to config.cfg on exit), it is recommended that set and seta commands be placed in default.cfg for mod-specific cvars.
70 //darkplaces implementation: LordHavoc
72 //indicates this engine supports the "seta" console command which creates or sets an archived cvar (saved to config.cfg on exit), it is recommended that set and seta commands be placed in default.cfg for mod-specific cvars.
74 //DP_CON_ALIASPARAMETERS
76 //darkplaces implementation: Black
78 //indicates this engine supports aliases containing $1 through $9 parameter macros (which when called will expand to the parameters passed to the alias, for example alias test "say $2 $1", then you can type test hi there and it will execute say there hi), as well as $0 (name of the alias) and $* (all parameters $1 onward).
82 //darkplaces implementation: Black
84 //indicates this engine supports console commandlines containing $cvarname which will expand to the contents of that cvar as a parameter, for instance say my fov is $fov, will say "my fov is 90", or similar.
88 //darkplaces implementation: LordHavoc
90 //adds two engine-called aliases named startmap_sp and startmap_dm which are called when the engine tries to start a singleplayer game from the menu (startmap_sp) or the -listen or -dedicated options are used or the engine is a dedicated server (uses startmap_dm), these allow a mod or game to specify their own map instead of start, and also distinguish between singleplayer and -listen/-dedicated, also these need not be a simple "map start" command, they can do other things if desired, startmap_sp and startmap_dm both default to "map start".

157 //other entities - no effect
159 //disabling gun bobbing on a diving mask or other model used as a .viewmodel.
160 //disabling gun bobbing on view-relative models meant to be part of the heads up display. (note: if fov is changed these entities may be off-screen, or too near the center of the screen, so use fov 90 in this case)

198 //darkplaces implementation: LordHavoc
202 //controls opacity of the entity, 0.0 is forced to be 1.0 (otherwise everything would be invisible), use -1 if you want to make something invisible, 1.0 is solid (like normal).
206 //darkplaces implementation: LordHavoc
210 //controls color of the entity, '0 0 0', is forced to be '1 1 1' (otherwise everything would be black), used for tinting objects, for instance using '1 0.6 0.4' on an ogre would give you an orange ogre (order is red green blue), note the colors can go up to '8 8 8' (8x as bright as normal).
212 //DP_ENT_CUSTOMCOLORMAP
214 //darkplaces implementation: LordHavoc
216 //if .colormap is set to 1024 + pants + shirt * 16, those colors will be used for colormapping the entity, rather than looking up a colormap by player number.
219 //NOTE: no longer supported by darkplaces because all entities are delta compressed now
220 //DP_ENT_DELTACOMPRESS // no longer supported
222 //darkplaces implementation: LordHavoc
224 float EF_DELTA = 8388608;
226 //(obsolete) applies delta compression to the network updates of the entity, making updates smaller, this might cause some unreliable behavior in packet loss situations, so it should only be used on numerous (nails/plasma shots/etc) or unimportant objects (gibs/shell casings/bullet holes/etc).
229 //DP_ENT_EXTERIORMODELTOCLIENT
231 //darkplaces implementation: LordHavoc
233 .entity exteriormodeltoclient;
235 //the entity is visible to all clients with one exception: if the specified client is using first person view (not using chase_active) the entity will not be shown. Also if tag attachments are supported any entities attached to the player entity will not be drawn in first person.
239 //darkplaces implementation: LordHavoc
245 //customizable glowing light effect on the entity, glow_color is a paletted (8bit) color in the range 0-255 (note: 0 and 254 are white), glow_size is 0 or higher (up to the engine what limit to cap it to, darkplaces imposes a 1020 limit), if glow_trail is true it will leave a trail of particles of the same color as the light.

257 //darkplaces implementation: LordHavoc
261 //controls rendering scale of the object, 0 is forced to be 1, darkplaces uses 1/16th accuracy and a limit of 15.9375, can be used to make an object larger or smaller.
265 //darkplaces implementation: LordHavoc
267 .entity viewmodelforclient;
269 //this is a very special capability, attachs the entity to the view of the client specified, origin and angles become relative to the view of that client, all effects can be used (multiple skins on a weapon model etc)... the entity is not visible to any other client.

296 //darkplaces implementation: LordHavoc
298 //loads external textures found in various directories (tenebrae compatible)...
300 in all examples .tga is merely the base texture, it can be any of these:
302 _glow.tga (fullbrights or other glowing overlay stuff, NOTE: this is done using additive blend, not alpha)
303 _pants.tga (pants overlay for colormapping on models, this should be shades of grey (it is tinted by pants color) and black wherever the base texture is not black, as this is an additive blend)
304 _shirt.tga (same idea as pants, but for shirt color)
305 _diffuse.tga (this may be used instead of base texture for per pixel lighting)
306 _gloss.tga (specular texture for per pixel lighting, note this can be in color (tenebrae only supports greyscale))
307 _norm.tga (normalmap texture for per pixel lighting)
308 _bump.tga (bumpmap, converted to normalmap at load time, supported only for reasons of tenebrae compatibility)
309 _luma.tga (same as _glow but supported only for reasons of tenebrae compatibility)
311 due to glquake's incomplete Targa(r) loader, this section describes
312 required Targa(r) features support:
314 type 1 (uncompressed 8bit paletted with 24bit/32bit palette)
315 type 2 (uncompressed 24bit/32bit true color, glquake supported this)
316 type 3 (uncompressed 8bit greyscale)
317 type 9 (RLE compressed 8bit paletted with 24bit/32bit palette)
318 type 10 (RLE compressed 24bit/32bit true color, glquake supported this)
319 type 11 (RLE compressed 8bit greyscale)
320 attribute bit 0x20 (Origin At Top Left, top to bottom, left to right)
322 image formats guaranteed to be supported: tga, pcx, lmp
323 image formats that are optional: png, jpg
325 mdl/spr/spr32 examples:
326 skins are named _A (A being a number) and skingroups are named like _A_B
327 these act as suffixes on the model name...
328 example names for skin _2_1 of model "progs/armor.mdl":
329 game/override/progs/armor.mdl_2_1.tga
330 game/textures/progs/armor.mdl_2_1.tga
331 game/progs/armor.mdl_2_1.tga
332 example names for skin _0 of the model "progs/armor.mdl":
333 game/override/progs/armor.mdl_0.tga
334 game/textures/progs/armor.mdl_0.tga
335 game/progs/armor.mdl_0.tga
336 note that there can be more skins files (of the _0 naming) than the mdl
337 contains, this is only useful to save space in the .mdl file if classic quake
338 compatibility is not a concern.
340 bsp/md2/md3 examples:
341 example names for the texture "quake" of model "maps/start.bsp":

1145 //entity customization is done before per-client culling (visibility for instance) because the entity may be doing setorigin to display itself in different locations on different clients, may be altering its .modelindex, .effects and other fields important to culling, so customized entities increase cpu usage (non-customized entities can use all the early culling they want however, as they are not changing on a per client basis).
