`func_train`

func_train is a brush entity available in all GoldSrc games. This entity creates an object that can move between multiple path_corners.

Key Values

Targetname:

Name (targetname) <targetname>: The targetname that other entities refer to this entity by.

Global:

Global Entity Name (???) <string>: Name to identify entity accross level transitions. Entities with the same global name will have the same status accross maps.

First stop target (target) <targetname>: The name of the path_corner that the func_train should start at. If not set, the func_train will be at (0 0 0).

Speed (units per second) (speed) <integer>: The speed the func_train will move at in units/second.

Angular Veocity (y z x) (avelocity) <string>: Sets up axial rotation. Format: Y Z X.

Damage on crush (dmg) <integer>: If the player is caught between the func_train and a solid brush, this is the amount of damage he will sustain.

Minimum light level (_minlight) <string>: The minimum light level the train will have, even if its initial position in the editor is in a purely dark room. This is a very aggressive value, so even a value of 0.02 will make the train relatively bright.

Render FX (renderfx) <choices>: Render FX mode to use, for special effects.

FX Amount (1-255) (renderamt) <integer>: Controls transparency when using another render mode then normal. 0 is completely invisible, and 255 is opaque.
FX Color (R G B) (rendercolor) <color255>: Color to use by the specified render mode.
Also used to control the speed of scrolling textures; see func_conveyor for more information.

ZHLT:

ZHLT Light Flags (ZHLT 2.2+) (zhlt_lightflags) <choices>

Special lighting behavior. Only available if using Zoner's Half-Life Compile Tools.

Light Origin Target (ZHLT 2.2+) (light_origin) <targetname>: Used to define a target to sample lighting from.

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 func_illusionary; VHLT does not properly 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.

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.; 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.
