func_trackchange

GoldSrc

Source Engine

func_trackchange is a brush entity available in all GoldSrc games. This entity allows you to create a rotating platform that will switch a func_tracktrain's path, used mainly with player-controllable trains.

Key Values

Minimum light level (_minlight) <string>

Targetname:

Name (targetname) <targetname>

The targetname that other entities refer to this entity by.

Travel altitude (height) <integer>

Altitude to ascend or descend (use negative values for the latter, or 0 to disable altitude change).

Spin amount (train) <integer>

This is the amount in degrees the track will turn on its way up / down.

Train to switch (rotation) <targetname>

The Name of the train that is using the track.

Top track (toptrack) <targetname>

This is the Name of the last path_corner in the upper track.

Bottom track (bottomtrack) <targetname>

The Name of the first path_corner in the lower track.

Move/Rotate speed (speed) <integer>

The speed in units/sec that the track platform will move. If the Rotate Only flag is set this will be the speed of rotation only.

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.

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.

Flags

•  [1] : Auto Activate train

•  [2] : Relink track

•  [8] : Start at Bottom
     Moving track will start in the bottom position.

•  [16] : Rotate Only
     Track will not move up and down.

•  [64] : X Axis
     Rotate around the X axis.

•  [128] : Y Axis
     Rotate around the Y axis.

ZHLT:

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

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

• 0 : "Default"
• 1 : "Embedded Fix"
• 2 : "Opaque (blocks light)"
• 3 : "Opaque + Embedded fix"
• 6 : "Opaque + Concave Fix"

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.
