Unfortunately with Game Maker they do. You don't actually SEE the Object superclass, but it might as well be there, since all objects get the same predefined variables. I'm familiar with just building classes from nothing (as well as Structs/Structures) from using C++. I'll have to experiment with 2d arrays much more now in Game Maker. But they aren't necessarily THAT memory intensive. I've actually ran into lag from having way too many active objects, rather than having large arrays. You have given me something to think about in regards to trying out building a game within C++ though, thanks
