Add Local Force with a Rigidbody2D
Hello, I was wondering how to add local force to a 2D rigidbody. Normally I would use AddRelativeForce but that does not exist for 2d rigidbodys only normal rigidbodys. Basicly I want this to be local.
gameObject.rigidbody2D.AddForce(Vector2.right*power);
Thanks!
Do you mean you want the force to be applied to the 'right' relative to the object? If so just use the objects transform.right vector:
gameObject.rigidbody2D.AddForce(gameObject.transform.right*power);
This should work for 2D as there is built in conversion from Vector3's to Vector2's, and you only lose the Z component which isn't relevant for 2D. Note that I'm still very new to Unity 2D so I'm not 100% sure :)
the z component of a vector in 2d is only relevant if you have 2 objects overlaping and you want to describe wich one should be rendered above the other. A z value that is smaller than another will render closer to the camera. note that this only applies if both objects are on the same sorting layer.
Are you sure the Rigidbody2D.AddRelativeForce doesn't exist?
This was added along with many other 2d functions in 4.5
