Click the green flag to start recording, arrow keys to change directions and move around Press space to play the recording back (stop the project first), [S] key to save it, and [L] key to load a saved recording.
I wanted to see if it was possible to capture sprite data like positions and costumes and then be able to play them back like a video recording. Turns out, you can! I want to experiment with this more as this could be very useful in games, and animations (allowing you to play them live). Of course, this is just a test so don't use this in your own projects yet.
