 ** Description
 
 This script allows you to assign a button that will fix the player's
 direction when the button is pressed.
 
 This is useful if you wish to allow players to lock their direction while
 moving, for example if you want to  provide "strafe movement" by moving
 side to side.
 
 A switch is provided to enable or disable the button's direction fixing
 behavior. The switch must be turned on in order for the button to fix
 the player's direction. This may be useful when you are creating a cut-scene
 and you don't want player actions to affect it.
 
--------------------------------------------------------------------------------
 ** Installation
 
 In the script editor, place this script below Materials and above Main

--------------------------------------------------------------------------------
 ** Usage
 
 In the configuration, choose which button you wish to use to force direction
 fixing. By default it is button X, which is the "A" key on your keyboard.
 
 When this button is pressed, the player's direction will be fixed.
 
 If you are using the default input system and you are not sure which keys
 correspond to which buttons by default, you can check the keyboard settings
 when you playtest the game and press F1.
   
 The enable/disable switch is also available in the configuration.

  #-----------------------------------------------------------------------------
  # Overwrite. Couldn't figure out how to preserve original settings after
  # releasing direction fix button so I decided to just take this one out and
  # have it make a method call.
