What's the Most Efficient Way to Program This?

Well I'm actually developing in Game Maker, and while it is object oriented in the sense that there's inheritance and all of that, it doesn't necessarily have the same type of pointer setup C++ and Java have. Like I COULD have the game create objects floating in space that does almost exactly what you're stating up there, just accessed by their ID number (which would be about the same as using a memory location in C++/Java, AKA Pointer), but I feel like having that many objects floating around (which wouldn't be saved into the save file btw) would be unnecessary, since in Game Maker, objects have a lot of default variables from just being objects (imagine, all objects inheriting from an Object superclass, with tons of predefined variables).
