env_portal_path_track

An env_portal_path_track beam (top) versus the final effects (bottom)

env_portal_path_track is a point entity available in Portal series. It is an unfinished variant of path_track which produces a visible light rail along the path. It was presumably meant for the Unstationary Scaffold, but the final game uses regular path_tracks and env_beams for this.

Bug:A func_tracktrain cannot start at an env_portal_path_track. It can still follow them as long as the starting node is a regular path_track.  [todo tested in ?]

Bug:Copying an env_portal_path_track in Hammer will not automatically rename it or link the previous node.  [todo tested in ?]

Next Stop Target (target) <targetname>

The next node in the path. This can be another env_portal_path_track, or a regular path_track

Branch Path (altpath) <targetname>

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.

• 0 : No change
• 1 : Face direction of motion
• 2 : Face this path_track's angles
