Point Entity

Multiple path_corners form a path that can be followed by various moving entities, including some monsters and the func_train.

Attributes

Name (targetname) - Property used to identify entities.
Pitch Yaw Roll (angles) - Sets the pitch (up / down), yaw (left / right) and roll (bank) respectively. The compass in WorldCraft / Hammer corresponds to Yaw. The settings are not always (or not all) used.
Next stop target (target) - Name of the next path_corner in the path.
Fire On Pass (message) - Trigger this event when this path_corner is passed by the entity using the path (blah!).
Wait here (wait) - Wait for this number of seconds before moving to next corner.
New Train Speed (speed) - Speed of the train once it passes this path_corner.
New train rot. Speed (yaw_speed)

Flags

Wait for retrigger (1) - Moving entity will wait and will only continue when triggered.
Teleport (2) - Makes a func_train entity teleport to the current path_corner.
Fire once (4) - Will only fire its Fire On Pass" target once.

Inputs

Outputs

Notes

It's a good idea to establish a simple path_corner naming convension. E.g. 'mypath1_1', 'mypath1_2', 'mypath1_3'.

weird bug i had once regarding path corners. I grouped 4 pathcorners together, and somehow the fire on pass value i had for only 1 out of 4 paths, was copy/pasted to all 4 path_corners!

afaik, it's only happened once, but something to keep in mind if you're having trouble with path corners.

stop!

better use func_tracktrain it doesn't need any corners

New train rot. Speed (yaw_speed) was listed as an attribute but that doesn't seem to be implemented, so I removed it

does func_traintrack supports path_corner or its only path_tracks that makes it moves

C0JJ, func_tracktrain uses path_track only. I have updated the article to clarify

Fun fact: the logic of picking movement waypoints of a func_train is entirely within func_train itself. It is therefore possible to make a valid path with other entities mixed in. I've successfully mixed path_corner's with momentary_doors like this:

path_corner (`p1`)

target = m1
wait = 0
spawnflags = Teleport (2)

momentary_door (`m1`)

target = p2
wait = 0

path_corner (`p2`)

target = m2
wait = 0
spawnflags = Teleport (2)

momentary_door (`m2`)

target = p1
wait = 0

I can then use momentary_rot_button to move the momentary_door's around and vary the distance the func_train has to travel.

It is a setup for an experiment where I can vary the time a func_train spends on one part of the map vs the other because it's being used to occlude LOS between me and a monster to test its AI schedule but that's off topic.

But you can likewise use it to have dynamically timed sequence with the mom_doors and func_train's off the playable areas.

My theory is that func_train's check the keyvalues of the entities it uses as paths (usually path_corner's) without checking that their classname is actually path_corner. You can therefore use any entity as long as it has keyvalues that concur with that of path_corner's: a target, optionally a wait, message (fire on pass) or speed, and spawnflags that don't conflict with that of a path_corner (therefore flag 1 will stop the func_train, flag 2 will teleport, etc.)

[2024-09-22] Most monsters use "target" to patrol `path_corner`s. Should denote all attributes on whether they apply to [Apaches/Ospreys/Monsters/Trains].

[2024-09-23]
List of monsters that patrols path_corners in their target kvs: Need to update the target attribute in their pages. For all others, also need to update that target does nothing.

[2024-10-07]

tidied up formatting for this comment for some reason.
Added trigger_camera and func_guntarget to page
Changed lists to tables on account of there being like 6 different use cases for this entity now
