I’m using CharacterController to move my character. My character has collider with Trigger tag. Also I have a door with two colliders - one for physic and second with the Trigger tag. With this components I can’t get OnTriggerEnter handler when character nigh to the door. If I adding Rigidbody into my door instead triggered collider OnTriggerEnter handler successfull works but my character may “jump” in to second floor when the door is opening and pushing character. How can I get a collider collision for CharacterController and without Rigidbody using?
I think you have things turned around. First one item of the two must have a Rigidbody for colliders to work. A collider marked as a Trigger will not interact using physics with a Rigidbody object whereas a standard collider will.
You can solve the problem in several ways; Increase the Trigger collider size as to trip the door animation earlier, prevent the player from moving while door animation is running, or disable the collider on the door while the door is animating. If you are using Unity’s CharacterController it already has a collider and you don’t need to add your own.
I just solved this issue. I have deleted Rigidbody from door object. For colliders intersection I use Raycast function into Update. I just tested this solution - works as planned. And I have deleted additional collider from character )
