This is not a game it can be used as an online engine that keeps track of two sets of x & y variables. - To start the online engine broadcast message zero. - Variables 15 & 16 should be changed and represent "my" x & y positions. - Variables 17 & 18 should not be changed and represent "opponents" x & y positions. - Variable 19 can be changed and represents the wait in between updates to the x & y positions. Remember that when adding this to your scratch game you must make variables one and two into cloud variables(Depending on how you add it, Scratch will add the cloud variable image but it will work like a normal variable).
