Question by Cippman · Jun 06, 2019 at 10:08 AM · bugmeshcolliderboxcollider

Mesh Collider not detected by Box Collider Trigger (using unity 2018.4 lts)

Hello,

I'm using a small box collider (trigger) moved by the player (size 0.02f, 0.01f, 0.01f). When I try to detect a convex cylinder mesh collider (not trigger) (size 0.07f, 0.03f, 0.07f) it doesn't work. From physic debugger I can see that these collider are really overlapping each other, but on trigger enter is never called.

I tried to use another box collider instead of mesh-collider convex from a cylinder and it works but I'd like to have more accuracy and use a cylinder mesh collider convex instead of a bigger box collider for the cylinder

Any suggestion? C.

I didn't forget the rigidbody :)

However actually I workarounded/solved it by using a "ring of box colliders" that acts as the cylinder collider (I don't know if it's more expensive use 20 box collider or one cylinder mesh collider but in this case I prefer accuracy).

However I attach a screenshot of the problem if you have any other ideas. alt text
