Trigger collision response for scene and props

[Genebris]

I'm trying to make a trigger that will detect collisions with characters, scene and props, but it seems like trigger response type works only for characters.

Collision:SetResponse(10, Collision.Scene, 2)
Collision:SetResponse(10, Collision.Prop, 2)
Collision:SetResponse(10, Collision.Character, 2)
self.entity:SetCollisionType(10)

This makes my entity work as trigger for characters, but it collides with props and scene. Using 1 as a third parameter makes it collide with everything, using 0 makes it collide with nothing.

Is it a bug or intended? Or am I doing something wrong?

The way the collision types and responses were set up a couple of months ago when I last checked:

List of inherent types:

Collision.Prop = 1

Collision.Scene = 2

Collision.Character = 3

Collision.Trigger = 4

Collision.Debris = 5

Collision.Projectile = 6

Collision.LineOfSight = 7

 

List of possible responses:

Collision.None = 0

Collision.Collide = 1

Collision.Trigger = 4

 

With the following warning from Josh concerning using the constants and not the numerical values: "You really should stick to using the named constants. Technically, the values of these are allowed to change at any time, without breaking the spec."

 

So in your case, try:

Collision:SetResponse(10, Collision.Scene, Collision.Trigger)
Collision:SetResponse(10, Collision.Prop, Collision.Trigger)
Collision:SetResponse(10, Collision.Character, Collision.Trigger)
self.entity:SetCollisionType(10)

This works, thank you. But I have a different problem now: my trigger now detects collision only with models, not with brushes. I have a default shelf model and a brush primitive. They both have collision type scene and GetCollisionType() returns 2 for both of them, but my trigger detects collision with brush only if it has mass or script attached. Can I do anything about it?

Hmmm... that's a little unexpected. But the engine does "collapse/optimize" all brushes that have no mass or a script so maybe it is intended? Sounds like you can just add an empty script to the brushes as a workaround for the time being until maybe Josh can chime in with a response.

Ok, shouldn't be a big problem, thanks for your help.
