func_tracktrain

GoldSrc

Source Engine

func_tracktrain is a brush entity available in all GoldSrc games. This entity allows you to create a player-controllable train / platform etc. that follows a path consisting of path_tracks. Unlike func_trains, func_tracktrains will turn to face the next path_track, similar to how real world trains behave.

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>

Sound (sound) <choices>

#t	Description
0	None
1	Rail 1
2	Rail 2
3	Rail 3
4	Rail 4
5	Rail 6
6	Rail 7

Distance between the wheels (wheels) <integer>

The distance to the train's "front wheels", calculated forwards from the train's origin. This determines the heading, or the angle the trains face when turning corners.

Height above track (height) <integer>

This is the height above the path_track that the train will ride, based on the location of the train's origin brush.

Initial speed (startspeed) <integer>

The speed the train starts at, until overridden by player control or path_track settings.

Speed (units per second) (speed) <integer>

The maximum speed the player can make a controllable train go in units/second. The global entity speed limit is 2000.

Damage on crush (dmg) <integer>

If train movement is blocked by the player, deal out this much damage.

Volume (10 = loudest) (volume) <integer>

Bank angle on turns (bank) <string>

This is the angle the train will tilt when cornering.

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.

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

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 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 (???) <string>

Used to define a target to sample lighting from.

Flags

•  [1] : No Pitch (X-rot
     Enabling this will make the train rotate on the Z axis.

•  [2] : No User Control
     Removes the player's ability to control the train.

•  [8] : Passable
     Makes train non-solid.
