OnTriggerEnter(Collider other) own collider?

How can I get my collider when I collide with another BoxCollider? I have a plane with two BoxColliders and I need to know which collisioned with the other collider.

 

One way is to attach a script to each of your colliders with OnTriggerEnter(Collider other) implemented. And when other collider triggers any of your box colliders simply Debug.Log(this.name); where this refers to the plane collider that detected the collision.

 

With your reply I assume that for my plane I need a GameObjects structure like this:

 

Yeah. IsTrigger should be checked. Note that they will only be used as triggers, they will detect collision but they won't do anything apart from that. Now you should attach a script for example Detection.cs and in OnTriggerEnter(Collider other) call Debug.Log("Collider that detected collision is: " + name);
