// XS Pet walk on a moon pose ball

// :CODE:

// walk on a moon pose ball
// Put this script into a pose ball and set it near your Sphere world.
//  This allows the person to actually welk on your world using the arrow ketys

// Requires there to be one Walk animation in the inventory of the pose ball.







// START OF COPIED file 'Global Constants.txt' from the Debug folder.  It has to be the same in all files
// If you change this in any script, change it in all of them, please. It works a lot better that way.
