MoveDirection.Right

설명

This is the Right state of MoveDirection. Assign functionality for moving to the right.

Use the Right state for an easily identifiable way of moving a GameObject to the right (1 , 0 , 0). This is a state without any predefined functionality. Before using this state, you should define what your GameObject will do in code.

//Attach this script to a GameObject with a Rigidbody component. Press the "Move Right" button in Game view to see it in action.
