Waits until the next frame rate of FixedUpdate function. (For more details have a look at Appendix A, Important Functions.)
WaitForFixedUpdate can only be used with a yield statement in coroutines.
Example
function Start() {
// Wait for FixedUpdate to finished
yield new WaitForFixedUpdate();
// Call After FixedUpdate
Debug.Log ("Call after FixedUpdate");
}
function FixedUpdate() {
Debug.Log ("FixedUpdate");
}
