Someone asked me by PM for some moving back and forth automatically code.
I knew that I could do it with about 10 lines by going "If [X] >= 224 ; Start Block ; Move the other way..."
But I decided to keep it small and simple so here it is:
Set Variable,[X];[X]+(Direction?1:-1),this
Set Variable,Direction;[X]!=160?[X]!=64?Direction:1:0,this
The numbers in bold you can change for the co-ordinates that it moves to.
You have to declare Direction in the Variable menu as a Boolean starting at 1 or it will give you a compile error.
Here it is compiled:
