Question Non-Spherical Invisible Collisions Trigger?

[TreyWilly]

I would like to have a square (door shaped) collision trigger. I know that you can make a cube or other asset to be a collision trigger, and you can set alpha to 0 to make it invisible, but it still has collision so you cannot really walk through it, in VR at least, as your hands will get stuck. Is there any way to make a cube (flat, so a rectangle to be precise) so hands can pass though it but also trigger the collision? Thanks!

What is this even for? That might help others provide solutions to your problem

For example to trigger an event when you walk through a door or hallway. Instead of having a hovering sphere which usually needs to be scaled up to a massive size to make sure that the player or person doesn't miss it, a trigger that fits nicely into the door space would be more convenient.

You could put an invisible square (in the shape of a rectangle) in the doorway and set the collision trigger to simultaneously set off whatever you want it to, in addition to turning off the collision of the square.

If you need to reset the doorway trigger, you could put another invisible "square" on the floor in front of the door as a sort of pressure plate to reactivate the doorway trigger.

That worked perfectly, thanks.
