Something I was wondering. Is there much difference (in terms of CPU, memory usage, etc) between an object with a complex animation vs multiple objects using behaviors to simulate an animation?
For example, a spinning propeller with two coaxial rotors. I can either have two sprite objects spinning, or I can have one sprite object with the animation of two rotors spinning. The animation option seems like it'll use a lot more disk space for the sprites, but would there be any appreciable difference in runtime efficiency? Supposing lots of instances of said objects and liberal use of effects? On mobile? On PC?
