Use mask types (or invisible collision sprite) as collisions instead of the sprites? thats what Im doing for my project.
That's what I've been doing, but after 150 plus layouts it gets tedious and there should be some kind of method of specifying a tile or tiles that can be designated as solid or even platform objects. It strikes me knowing what I know that it IS possible, but I lack the general skill to just do it, it would take a month or so of reviewing old code, experimenting, and implementing it without bugs. Surly there is someone here more familiar with the processes involved.
