i am planing to port my game from “MadeWithMarmalade” to Godot. Right now i have all the sprites in few textures (atlases) and corresponding files with positions of each sprite-frame in the texture-atlas. I also programmed all the drawing and frame animation routines myself. Before i go and reinvent the wheels in Godot, are there already any support for this kind of texture-atlas animation stuffs?
