I have a basic character with a character controller and capsule collider. There’s a picture attached.
I’ve parented some objects to it to represent his weapon, and added a swinging animation. I’ve attached a box collider and a script to the rectangle object, but it never seems to fire. Neither OnCollisionEnter or OnTriggerEnter work on that object, even though I’ve tested the same script on other objects.
Not sure how you’re using constraints but it’s easiest by just setting the rigidbody in question to be kinematic. Don’t use the those movement/rotation constraints in the inspector. Kinematic will keep it a rigidbody while also letting you control it’s placement rather than the physics engine.
