Hi everybody,

I've got a schoolassignment where i need to make a 'Maul'.
I haven't got much experience with GML, and i was wondering how you can make a creep walk the fastest way to the "Castle". I got a script from http://gmlscripts.com/script/motion_towards,  and i understand the most of it, but when i make a maze where the creeps have tho go backwards a bit, the creep will go from the left to the right and from the right to the left, and so on.
Anyone has any ideas?
(plz don't say anything about my bad English, because i'm from Holland)
