Someone posted a thread a few minutes ago about how to animate their game's sprites.

I took ten minutes to put together an image showing a neat technique for handling walk cycles:

Unfortunately, they deleted their own thread seconds before I could respond.



And for a .gif of this animation cycle in action:




In order to figure out how far the player will move each step, you need to know two things:

The width and height of tiles in your world. How many frames it takes to move from one tile to another.

In my case, each of my animation frames has a duration of 1 frame, and I have 8 of them. It takes 8 frames to move from one tile to another, and my tiles are 16x16.

16 pixels / 8 frames * 1 frame delay = 2 pixels per frame.

That's how I figured out that the pivot foot should move 2 pixels per frame in order for the animation to sync smoothly.
