Func wall (GoldSrc)

GoldSrc

Source Engine

func_wall is an e2 available in all GoldSrc games.

Warning:

• The {{{engine}}} parameter is inconsistent with the name defined by the {{gldsrc}} template. This can most likely be fixed by setting the value of the {{{engine}}} parameter to GoldSrc .
  If a parameter is consistent but you're still seeing this warning, it may be an issue with the template itself. Please discuss it on the template's talk page.

It is used to create a stationary piece of geometry (with collision) that uses a non-standard render mode, such as transparency.

Formerly, it was also used for visibility optimization, but this use-case has been deprecated by ZHLTs func_detail. Nonetheless, func_wall can still sometimes be useful for reducing wpolies, particularly for geometry that intersects other geometry (ex: shelves); this should be used sparingly, though, since func_wall counts as an edict, whereas func_detail does not ( elaboration on TWHL).

Key Values

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Render FX (renderfx) <choices>

Render FX mode to use, for special effects.

Value	Description
0	Normal
1	Slow Pulse
2	Fast Pulse
3	Slow Wide Pulse
4	Fast Wide Pulse
5	Slow Fade Away
6	Fast Fade Away
7	Slow Become Solid
8	Fast Become Solid
9	Slow Strobe
10	Fast Strobe
11	Faster Strobe
12	Slow Flicker
13	Fast Flicker
14	Constant Glow
15	Distort
16	Hologram (Distort + fade)

Render Mode (rendermode) <choices>

Render Mode to use.

Value	Description
0	Normal
1	Color
2	Texture
3	Glow
4	Solid
5	Additive

Render Amount (0-255) (renderamt) <integer>

Controls transparency when using another render mode then normal. 0 is completely invisible, and 255 is opaque. If render mode is solid, then all values except 0 are opaque.

Render Color (R G B) (rendercolor) <color255>

Color to use by the specified render mode.
Also used on brush entities to control the speed of scrolling textures; see func_conveyor for more information.

Global Entity Name (globalname) <string>

Name to identify entity accross level transitions. Entities with the same global name will have the same status accross maps.

Minimum light level (_minlight) <normal>

ZHLT family

ZHLT Light Flags (ZHLT 2.2+) (zhlt_lightflags) <flags> Special lighting behavior. Only available if using Zoner's Half-Life Compile Tools or a fork thereof. Embedded Fix : [1] Opaque (blocks light) : [2] Concave fix : [4] Note:Most FGDs will have this as "choices" with options for values of 0/1/2/3/6, because Hammer and Jack do not support the "flags" KV type outside of Spawnflags. Light Origin Target (ZHLT 2.2+) (light_origin) <targetname> During lighting compilation, this entity will be treated as if its origin were at the target entity's origin. Requires an origin brush. Entity to Use Model From (ZHLT) (zhlt_usemodel) <targetname> Used to set the model to a different entity's model (bmodel, BSP, MDL, or SPR). The targeted entity will be moved before this entity to ensure proper loading. Requires an origin brush on this entity, as well as on the target entity if target entity is a brush entity. Nonsolid (ZHLT) (zhlt_noclip) <boolean> Disables generation of clipnodes for all brushes on this entity, except for clip brushes. The entity may still be solid to point traces (hitscans, grenades, etc) if the brush contents are set to solid. Tip:Always enable this for cosmetic func_illusionary, (not if, for example, skin is set to -16 to make it a ladder); VHLT does not strip clipnodes for this entity. Don't Render (ZHLT 3+) (zhlt_invisible) <boolean> Treat all faces as if they were textured with NULL. Tip:Use this on triggers which use custom textures instead of AAATRIGGER or NULL, such as ladders. Custom Hull 1 (VHLT+) (zhlt_hull1) <targetname> Custom Hull 2 (VHLT+) (zhlt_hull2) <targetname> Custom Hull 3 (VHLT+) (zhlt_hull3) <targetname> Which named info_hullshape entity to use for the specified clipping hull. Mins/Maxs (VHLT+) (zhlt_minsmaxs) <mins vector + maxs vector> Override this entity's bounding box. zhlt_transform (zhlt_transform) <???> Never visible (VHLT+) (zhlt_hidden) <boolean> Don't create marksurfaces for this entity, resulting in it being treated by VIS as never visible. Tip:The _HIDDEN texture suffix does the same thing, but also works on world brushes, which are used for model lighting. Strip lightmaps after compiling (VHLT+) (zhlt_striprad) <boolean> Undefines the lightmaps for brushes on this entity after compiling, resulting in the faces being fullbright and not using up allocblock. Unlike TEX_SPECIAL, faces with zhlt_striprad will still affect bounced lighting. Custom Shadow Color (VHLT+) (zhlt_customshadow) <color1> If this entity casts shadows, the shadows will be this color instead of black. Can also be a single value, for monochrome. Fake Lightmap (VHLT v33+) (zhlt_embedlightmap) <boolean> Generates unique diffuse textures for all textured faces, then bakes lighting information directly into the generated textures. Primarily used to prevent translucent surfaces from "glowing", as rendermodes which support translucency don't render lightmaps on the vanilla renderer. Implies zhlt_striprad. Important:The resulting textures will be renamed to have the prefix __rad; as such, any unique attributes will be lost. Downscale Fake Lightmap (VHLT v34+) (zhlt_embedlightmapresolution) <integer> Downscale texture created by zhlt_embedlightmap this many times.

ericw-tools

Note:If any of the booleans are set in worldspawn, they can be disabled per entity by being set to -1. Cast shadows (_shadow) <boolean> Cast shadows from this entity. Implies _shadowself. Self-shadowed (_shadowself) <boolean> Cast shadows from this entity onto itself. Shadow world only (_shadowworldonly) <boolean> Only cast shadows on world, not models. Smooth shading (_phong) <boolean> Enable smooth shading between faces which are less than _phong_angle. Autosmoothing angle (_phong_angle) <integer> Angle to smooth; default 89. Set to 44 to match QRAD/HLRAD defaults. Maximum light level (_maxlight) <normal> Minlight color (_mincolor, _minlight_color) <color1> Color of _minlight. Also accepts color255, provided at least one value is greater than 1. Minlight only (_lightignore) <boolean> Only receive lighting from _minlight Disable backface culling (_mirrorinside) <boolean>

Minimum light level (_minlight) <string>

Flags

Not In Deathmatch : [2048]

Prevent this entity from attempting to spawn when deathmatch (multiplayer) is enabled.
