I was initially looking to use a single texture, and replacing the texture as needed. I found this discussion:
This is beyond my skills, because it relies on shaders, which, as anyone knows, is impenetrable black magic.
So, I’m trying to figure out whether keeping game objects on stage and disabling/enabling them would work best in my case, or if creating them on the fly with Factory is likely to work better. My gut tells me Factory, because it would be more scalable.
