Rigidbody.AddForceAtPosition 在位置上添加力

function AddForceAtPosition (force : Vector3, position : Vector3, mode : ForceMode = ForceMode.Force) : void

public class example : MonoBehaviour {
	void ApplyForce(Rigidbody body) {
		Vector3 direction = body.transform.position - transform.position;
		body.AddForceAtPosition(direction.normalized, transform.position);
	}
}

function ApplyForce (body : Rigidbody) {
	var direction : Vector3
