MoveDirection.None

Description

This is the None state. Assign functionality that stops movement.

Use the None state for an easily identifiable way of stopping, resetting or initialising a GameObject's movement. 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 attached. This script starts off on the ModeDirection.None state but changes depending on buttons you press.
