Hi tarek, sorry for not replying yesterday. I was swamped... Alright, so I went back and had a look at what I came up with. I ended up using the event-sheet and a 2D array.
Patrol 0 is moving left and patrol 1 is moving right.
I only use the scripting when I can't get something to work with the event-sheet. Which is not often.
Let me know if you have any additional questions.
