Func tracktrain

Template:Base brush It functions as a moving platform that the player can ride. It follows a path of path_track entities.

Note:Unless the Fixed Orientation flag is set, build your train so that the front of the train is facing down the X axis. (This means that the front of the train is visible in the front view, etc..) When it spawns it will automatically rotate to face the next path_track on the path.

Individual keyvalues and flags

Todo: Since the keyvalues and flags are currently templated to multiple entities, the individual data for this entity is written in this section until all the other entities having these templates has been researched (and found either similar or diverse).

• orientationtype

<choices> How/If the train should change its angles as it travels.

Literal value	Description	Effect
0	Never (fixed orientation)	The orientation of the train is fixed (instead of being relative to the direction of the track) permanently facing the direction it was spawned in (according to the direction of the first track). This overrides the Orientation Type settings of its path_track. Does not turn around when reversing direction.
1	Near path_tracks	The train changes direction upon nearing a path_track. Does not turn around when reversing direction.
2	Linear blend	Very weird orientation that is choppy in corners. (Please find a use for it.) Turns around when reversing direction.
3	Ease in/ease out	Seemingly the same orientation as Linear blend. Turns around when reversing direction.

• 16 : Fixed Orientation - The orientation of the train is fixed (instead of being relative to the direction of the track) permanently facing the direction it was created in (prior to spawn). Overrides both the "Change angles" keyvalue setting of this func_tracktrain, and the Orientation Type settings of its path_tracks.

• 128 : HL1 Train - Set this flag if you want the player to be able to ride on or in a train while it is moving rapidly, or accelerating. (At least in Portal--I haven't tested this flag with a Half Life 2 map.) Not setting this flag will cause the player to be knocked off the train (and take blocking damage, if set) when he bumps into collision surfaces parented to it (sometimes.)

Template:In code

Inputs

Backward movement

Due to coding errors or engine limitations, the Reverse and StartBackward may not function correctly if the "New Train Speed" property in the involved path_track entities is set to 0. The train may fail to reverse, jamming in place or moving in the wrong direction. To solve this issue, some or all of the path_tracks must have their "New Train Speed" variable set to a nonzero value.
