Collision Dection / Avoidance

Unity Engine
1

Hi,

I have a character walking on a plane and a free camera moving on that plane.

Now I want to be informed whenever the characters feet (box collider attached) touch the ground (plane) without avoiding that collision.

On the other hand I have a free camera for which i need collision avoidance with that same plane.

How can I do this?
As far as I know for only collision detection i have to set the “Is Trigger” flag. But what can I do if I want the plane to be a trigger for one object and a collider for another one?

In that case you’d leave isTrigger off for the plane and set the one you want a trigger for to be isTrigger = true.

To test collisions, you use the function OnCollisionEnter. To test triggers, you use the function OnTriggerEnter.

oh :). great - that easy…!
