I am about to start working on a 2D animation system using spritesheets. Below are my plans for this system, but before I implement it I thought I would ask for some thoughts and opinions.
- Not all frames in all animations are of the same size. I then map each frame to a rectangle with the size of the frame which will save me a few bytes of memory.
- I plan to have an array of frame times to allow different frame time for each frame. Will make it easier to control the animation.
Good? Bad?
I am also curious about how to best implement some kind of achor point. A simple example, a guy is standing straight (thin and high frame), then falling over (wide and low frame). Using either of the corners as an anchor point, the "standard/default" way, would result in the guy not only falling over, but also moving sideways on the screen. To solve this the anchor point needs to be set to the feet. Right? If so, I will also need an array for the anchor point for each frame, where the anchor point will indicate how much to move the sprite up/down and left/right. Or?
Am I missing something? Better way of doing things?
