Attributes

• Name (targetname) - Property used to identify entities.
• Render FX (renderfx) - Gives objects special render effects. Think of it as modifying whatever the Render Mode puts out. The options are as follows:
  • 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 and Fade)
• Render Mode (rendermode) - Controls the type of rendering that is used for an object. Options are:
  • 0 = Normal
  • 1 = Color
  • 2 = Texture
  • 3 = Glow
  • 4 = Solid
  • 5 = Additive
• Global Entity Name (globalname) - If your train is going to cross level transitions, it'll need a global name.
• FX Amount (renderamt)
• FX Color (rendercolor)
• ZHLT Lightflags (zhlt_lightflags)
• Light Origin Target (light_origin) - Overrides the position from which the train will receive its lighting when the map compiles. Useful if the train doesn't have the correct lighting in-game. This can be used with an info_target.
• First stop Target (target) - The name of the path_track to start at.
• Sound (sounds) - Values:
  • 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) - This determines how the train behaves when turning corners. Generally the length of the object works here.
• Height above track (height) - 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) - The speed the train starts at, until overridden by player control or path_track settings.
• Speed (speed) - The maximum speed the player can make a controllable train go in units/second.
• Damage on crush (dmg) - If train movement is blocked by the player, deal out this much damage.
• Volume (volume) - Range: 0 - 10.
• Bank angle on turns (bank) - This is the angle the train will tilt when cornering.
• Minimum Light Level (_minlight) - 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.

Flags

• No pitch(X-rot) (1) - Enabling this will make the train rotate on the Z axis only (yaw - left and right)
• No User Control (2) - Removes the player's ability to control the train (free ride to death?... yeah!)
• Passable (8) - Makes train non-solid.

Notes

• When you create the brush model it must face west (90 degrees - to the left in the top view). When it spawns in the game it will automatically move to the first path_track and orientate itself to face the second path_track.
  • Sometimes the entity might require an 180 degree turn to appear correctly in-game, instead of 90. The cause of this is unknown (possibly an engine bug?)
• Changing the degrees in the yaw circle won't affect the direction that the func_tracktrain faces in-game. The degrees in the yaw circle in the path_track don't change anything either.
• func_traincontrol entities allow the player to control the train. They are not part of the func_tracktrain and their placement only determines the area of use. They will automatically stay in that area relative to the train as it moves.
• An origin brush needs to be part of the entity to specify its axes.
• This is one of the few entities that can have 'clip' brushes as part of itself, which prevent player movement (i.e. to stop the player falling off the sides).
