Well, I've just recently started to create a sprite manager class that can add, remove and render sprites to the screen. I have to convert all of the sprite's vertices and texture coordinates into a float[], since I'm using Vertex Arrays in OpenGL. My question is, would recreating the array every frame (since I have to sort the sprite's by their Z value and texture ID) be a feasible thing to do on an average computer? Or should I find some other method of managing my sprites?
