OnTriggerEnter() without rigidbody?

Question

I know this is an old question and it has been answered for a lot of people. Unfortunately none of the solutions apply to the problem I seem to have with rigidbodies.

I have a moving AI character and the playermodel. When the AI gets to close the player just bumps on top of it. If I unattach the rigidbody from the moving AI this does not seem to be a problem. My player is controlled by a charactercontroller and the rigidbody is set to "Is Kinematic".

Of course, when none of the agents has a rigidbody my entire combat mechanic falls apart. Does anyone have any idea on how to solve this?

For clarity, here is a short demonstration of the bug: Bump

And the code in question:

void FixedUpdate ()
{
    if (!controller.isGrounded) 
    {
        movement.y -= gravity * Time.deltaTime;
    }
    controller.Move (movement * Time.deltaTime);
}

void CalcMovement (float h, float v)
{
    movement = new Vector3 ();

    if (v != 0 || h != 0) {
        movement = v * forward + h * right;
        movementDirection = movement.normalized;
    }
}

Answer 1

This is not quite what I hoped for, but it did solve the problem of the bouncing. I replaced the rigidBody and the capsuleCollider with a CharacterController. I don't know if this is an efficient way of avoiding rigidBodies and still having collision and trigger detection, but it's a working way.

Answer 2

You can have a try to remove the rigid body from your player. A Character Controller component contains rigid body and Collider
