Turn spritesheets into game-ready animations!

This is a tool I developed to convert spritesheets (ripped from video games) into animations you can use in your games. The tool uses computer vision algorithms to isolate individual frames from spritesheets you download from game fan sites. You then select frames to add to an animation.

It doesn't stop there.

Then, you can select an isolated segment of one of the frames (one that you can see is common to all the frames), and then click "Align Frames". The system will then use your segment to align the frames, so they animate nice and smoothly, without any jumping around that makes your game look bad.

But there's more! You can also set the duration of individual frames on the timeline view. This can allow you to prolong certain gestures within the animation, for dramatic effects. When you're done, you can then export your animations to a set of film-strip png files, along with an XML master file that contains the description of each of your animations you've created. You can then load them into your game as you like!
