How to detect if camera is touching a gameobject ?

Hi! Just put a box collider (or any type of collider really) onto your camera. Then you can put a script onto your camera which will test if it's intersecting other colliders.

void OnCollisionEnter(Collision collision) { if (collision.gameObject.name == "MyGameObjectName") { Debug.Log("Do something here"); } }

P.S depending on whether or not you want to allow you camera to go through objects, you may want to switch the camera collider to IsTrigger and check for OnTriggerEnter.
