5 .float disableclientprediction;
7 //definitions that id Software left out:
8 //these are passed as the 'nomonsters' parameter to traceline/tracebox (yes really this was supported in all quake engines, nomonsters is misnamed)
9 float MOVE_NORMAL = 0; // same as FALSE
10 float MOVE_NOMONSTERS = 1; // same as TRUE
11 float MOVE_MISSILE = 2; // save as movement with .movetype == MOVETYPE_FLYMISSILE

14 //idea: expected by almost everyone
15 //darkplaces implementation: LordHavoc
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
22 //// (it is recommended this code be placed in worldspawn or a worldspawn called function somewhere)
23 //if (cvar("pr_checkextension"))
24 //if (checkextension("DP_SV_SETCOLOR"))
25 // ext_setcolor = TRUE;
26 //from then on you can check ext_setcolor to know if that extension is available
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".

149 //idea: Chris Page, Dresk
150 //darkplaces implementation: LordHAvoc
152 float EF_NOGUNBOB = 256;
154 //this has different meanings depending on the entity it is used on:
155 //player entity - prevents gun bobbing on player.viewmodel
156 //viewmodelforclient entity - prevents gun bobbing on an entity attached to the player's view
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)

178 //DP_EF_RESTARTANIM_BIT
180 //darkplaces implementation: divVerent
182 float EF_RESTARTANIM_BIT = 1048576;
184 //when toggled, the current animation is restarted. Useful for weapon animation.
185 //to toggle this bit in QC, you can do:
186 // self.effects += (EF_RESTARTANIM_BIT - 2 * (self.effects & EF_RESTARTANIM_BIT));
189 //idea: MythWorks Inc

192 float EF_STARDUST = 2048;
194 //entity emits bouncing sparkles in every direction
198 //darkplaces implementation: divVerent
200 float EF_TELEPORT_BIT = 2097152;
202 //when toggled, interpolation of the entity is skipped for one frame. Useful for teleporting.
203 //to toggle this bit in QC, you can do:
204 // self.effects += (EF_TELEPORT_BIT - 2 * (self.effects & EF_TELEPORT_BIT));
208 //darkplaces implementation: LordHavoc
212 //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).
216 //darkplaces implementation: LordHavoc
220 //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).
222 //DP_ENT_CUSTOMCOLORMAP
224 //darkplaces implementation: LordHavoc
226 //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.
229 //NOTE: no longer supported by darkplaces because all entities are delta compressed now
230 //DP_ENT_DELTACOMPRESS // no longer supported
232 //darkplaces implementation: LordHavoc
234 float EF_DELTA = 8388608;
236 //(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).
239 //DP_ENT_EXTERIORMODELTOCLIENT
241 //darkplaces implementation: LordHavoc
243 .entity exteriormodeltoclient;
245 //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.
249 //darkplaces implementation: LordHavoc
255 //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.
259 //darkplaces implementation: LordHavoc
263 //controls color of the entity's glow texture (fullbrights), '0 0 0', is forced to be '1 1 1' (otherwise everything would be black), used for tinting objects, see colormod (same color restrictions apply).
265 //DP_ENT_LOWPRECISION
267 //darkplaces implementation: LordHavoc
269 float EF_LOWPRECISION = 4194304;
271 //uses low quality origin coordinates, reducing network traffic compared to the default high precision, intended for numerous objects (projectiles/gibs/bullet holes/etc).
275 //darkplaces implementation: LordHavoc
279 //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.
281 //DP_ENT_TRAILEFFECTNUM
283 //darkplaces implementation: LordHavoc
285 .float traileffectnum;
287 //use a custom effectinfo.txt effect on this entity, assign it like this:
288 //self.traileffectnum = particleeffectnum("mycustomeffect");
289 //this will do both the dlight and particle trail as described in the effect, basically equivalent to trailparticles() in CSQC but performed on a server entity.
293 //darkplaces implementation: LordHavoc
295 .entity viewmodelforclient;
297 //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.
299 //DP_GFX_EXTERNALTEXTURES
301 //darkplaces implementation: LordHavoc
303 //loads external textures found in various directories (tenebrae compatible)...
305 in all examples .tga is merely the base texture, it can be any of these:
307 _glow.tga (fullbrights or other glowing overlay stuff, NOTE: this is done using additive blend, not alpha)
308 _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)
309 _shirt.tga (same idea as pants, but for shirt color)
310 _diffuse.tga (this may be used instead of base texture for per pixel lighting)
311 _gloss.tga (specular texture for per pixel lighting, note this can be in color (tenebrae only supports greyscale))
312 _norm.tga (normalmap texture for per pixel lighting)
313 _bump.tga (bumpmap, converted to normalmap at load time, supported only for reasons of tenebrae compatibility)
314 _luma.tga (same as _glow but supported only for reasons of tenebrae compatibility)
316 due to glquake's incomplete Targa(r) loader, this section describes
317 required Targa(r) features support:
319 type 1 (uncompressed 8bit paletted with 24bit/32bit palette)
320 type 2 (uncompressed 24bit/32bit true color, glquake supported this)
321 type 3 (uncompressed 8bit greyscale)
322 type 9 (RLE compressed 8bit paletted with 24bit/32bit palette)
323 type 10 (RLE compressed 24bit/32bit true color, glquake supported this)
324 type 11 (RLE compressed 8bit greyscale)
325 attribute bit 0x20 (Origin At Top Left, top to bottom, left to right)
327 image formats guaranteed to be supported: tga, pcx, lmp
328 image formats that are optional: png, jpg
330 mdl/spr/spr32 examples:
331 skins are named _A (A being a number) and skingroups are named like _A_B
332 these act as suffixes on the model name...
333 example names for skin _2_1 of model "progs/armor.mdl":
334 game/override/progs/armor.mdl_2_1.tga
335 game/textures/progs/armor.mdl_2_1.tga
336 game/progs/armor.mdl_2_1.tga
337 example names for skin _0 of the model "progs/armor.mdl":
338 game/override/progs/armor.mdl_0.tga
339 game/textures/progs/armor.mdl_0.tga
340 game/progs/armor.mdl_0.tga
341 note that there can be more skins files (of the _0 naming) than the mdl
342 contains, this is only useful to save space in the .mdl file if classic quake
343 compatibility is not a concern.
345 bsp/md2/md3 examples:
346 example names for the texture "quake" of model "maps/start.bsp":
347 game/override/quake.tga
348 game/textures/quake.tga
351 sbar/menu/console textures: for example the texture "conchars" (console font) in gfx.wad
352 game/override/gfx/conchars.tga
353 game/textures/gfx/conchars.tga
354 game/gfx/conchars.tga

387 //note 2: if the tag is not found, it defaults to "" (attach to origin/angles of entity)
388 //note 3: attaching to world turns off attachment
389 //note 4: the entity that this is attached to must be visible for this to work

401 //these files contain replace commands (replace meshname shadername), example:

403 //replace "teamstripes" "progs/test/redstripes.tga"
404 //replace "visor" "common/nodraw" // this makes the visor mesh invisible

409 //teamstripes,progs/test/redstripes.tga
410 //visor,common/nodraw // this makes the visor mesh invisible
411 //tag_camera, // this defines that the first tag in the model is called tag_camera
412 //tag_test, // this defines that the second tag in the model is called tag_test
414 //any names that are not replaced are automatically show up as a grey checkerboard to indicate the error status, and "common/nodraw" is a special case that is invisible.
415 //this feature is intended to allow multiple skin sets on md3 models (which otherwise only have one skin set).
416 //other commands might be added someday but it is not expected.

506 //indicates this engine loads .lit files for any quake1 format .bsp files it loads to enhance maps with colored lighting.
507 //implementation description: these files begin with the header QLIT followed by version number 1 (as little endian 32bit), the rest of the file is a replacement lightmaps lump, except being 3x as large as the lightmaps lump of the map it matches up with (and yes the between-lightmap padding is expanded 3x to keep this consistent), so the lightmap offset in each surface is simply multiplied by 3 during loading to properly index the lit data, and the lit file is loaded instead of the lightmap lump, other renderer changes are needed to display these of course... see the litsupport.zip sample code (almost a tutorial) at http://icculus.org/twilight/darkplaces for more information.

1469 //implementation notes:
1470 //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).
