An entity used to build paths for other entities to follow. Each path_track is a node on the path, each holding the name of the next path_track in the path.
Name targetname <target_source> The name that other entities refer to this entity by.
Parent parentname <target_destination> The name of this entity's parent in the movement hierarchy. Entities with parents move with their parent.
Pitch Yaw Roll (Y Z X) angles <angle> This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
spawnflags spawnflags <flags>
Next Stop Target target <target_destination> The next path_track in the path.
Branch Path altpath <target_destination> An alternative path_track to be the next node in the path. Useful for making branching paths. Use the ToggleAlternatePath / EnableAlternatePath inputs to make the alternative path active.
New Train Speed speed <float> When the train reaches this path_track, it will set its speed to this speed. This speed must be a positive value that is less than the train's max speed. A value of 0 will cause no change in the train's speed.
Path radius radius <float> Used by NPCs who follow track paths (attack chopper/gunship). This tells them the maximum distance they're allowed to be from the path at this node.
Orientation Type orientationtype <choices> The way that the path follower faces as it moves through this path track.
Kill Removes this entity from the world.
KillHierarchy Removes this entity and all its children from the world.
AddOutput <string> Adds an entity I/O connection to this entity. Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire (-1 == infinite)>. Very dangerous, use with care.
FireUser1 Causes this entity's OnUser1 output to be fired.
FireUser2 Causes this entity's OnUser2 output to be fired.
FireUser3 Causes this entity's OnUser3 output to be fired.
FireUser4 Causes this entity's OnUser4 output to be fired.
SetParent <string> Changes the entity's parent in the movement hierarchy.
SetParentAttachment <string> Change this entity to attach to a specific attachment point on its parent. Entities must be parented before being sent this input. The parameter passed in should be the name of the attachment.
ClearParent Removes this entity from the the movement hierarchy, leaving it free to move independently.
ToggleAlternatePath Cause the track to toggle to/from its alternate path.
EnableAlternatePath Enable the alternate path of the track.
DisableAlternatePath Disable the alternate path of the track.
TogglePath Cause the track to toggle on/off/
EnablePath Enable the track.
DisablePath Disable the track.
OnUser1 Fired in response to FireUser1 input.
OnUser2 Fired in response to FireUser2 input.
OnUser3 Fired in response to FireUser3 input.
OnUser4 Fired in response to FireUser4 input.
OnPass Fired when any entity following this path passes this path_track node.
