Yeah, the sprite sheets that have the character mantling up do have a lot more transparency than a standard sprite in Siege so that we can do these larger moves within the flipbook frame, but we are masked 1-bit transparency rather than 8-bit full transparency so its not that costly. A little excessive on texture sheet usage and alpha overdraw for the few frames the character is climbing up but they are over fairly quickly so its not too bad and we aren’t hurting for texture memory with our little 2D game.
