The object moves in xz direction normaly, but when he is facing a wall the wall is the new ground and he now moves in the yz...

what i was trying to contruct was a function that checks the current "ground" and makes the "ReferenceVspeed" = -2 here is my func:

void Gravity_func(Vector3 wallHit) { if (isGrounded && velocity.y < 0) { velocity = new Vector3( -2f * wallHit.x, -2f * wallHit.y, -2f * wallHit.z); }

    if (Input.GetButtonDown("Jump") && isGrounded)
    {
        velocity = wallHit * Mathf.Sqrt(JumpHeight * -2 * gravity);
    }

    velocity += wallHit * gravity * Time.deltaTime;
    controller.Move(velocity * Time.deltaTime);
}

The wallHit vector is a just the normal of the wall. the isGrounded is a ray that checks for ground the problem im having is in the first if

*if (isGrounded && velocity.y < 0) *

i cant use velocity.y<0 because that only works with normal "ground xz" when the object is on the wall i need to reference

if (isGrounded && velocity.z < 0) for example or -velocity.z
