Entity Description

It is a leftover from Quake that ping-pongs between the start and end of a series of path_corners. It was mostly replaced by func_tracktrain in GoldSrc GoldSrc, but was still used for looping auto-scrolling backgrounds. In Source, the introduction of parenting has rendered this method obsolete. However, the entity is still functional.

Tip.pngTip:This entity is not affected by the turning inaccuracy issues that func_tracktrain is, making it a good alternative for fast-moving objects.
Icon-Bug.pngBug:It will always try to play sounds, regardless of whether they are actually specified. This can be set to Default.Null with a volume of 0 to play no sound.  [todo tested in ?]

KeyValues

Spawn path_corner (target) <targetname>
The name of the first path_corner in the train's path. The train will spawn at this path_corner.
Speed (speed) <float>
Speed at which the train moves.
Movement Sound (noise1) <string>
The sound to play when the train moves.
Stop Sound (noise2) <string>
The sound to play when the train stops moving.
Sound Volume (0-10) (volume) <float>
Volume of the sounds emitted when moving and stopping.
Crush Damage (dmg) <float>
Amount of damage to deal to entities blocking the train.
