Thanks for the quick response.And I have just realised I am an idiot.
I put this into a very old project that hadn't been updated properly. Putting it in a new project, it works fine.
I apologise for wasting your time
You are welcome!
Aw no worries, its always good to hear that my scrupt is causing no trouble, im about to update it to allow Y acis changing for each waypoint type.
Enjoy the waypint system ^^
