I am experiencing a frustrating issue that I have not encountered before. I guess you have already checked this - but is the Layer Collision Matrix in Project Settings correct?. However no collision gets detected when the Cylinder, which has a collider, passes the collider that has a trigger on it. I’m having an issue getting my trigger to work. The car. If the Raycast still does not hit - try and make a simple Raycast call (without unnecessary game logic) and the OnCollisionEnter does NOT work Instead of that, you should use OnControllerColliderHit when moving the CharacterController with Move So if OnTriggerEnter is not working for you, double check whether the collider you are colliding against is actually marked as trigger, via the Is Trigger checkbox on it, or whether your Character Controller has I’ve created a UI Panel with a Text as Child and in the Panel I added a Event Trigger: I want that clicking on the panel, it calls a function of another object. void For some reason, my left trigger worked, not the right trigger.
