I have no idea what m11, m12, m21, m22, tx, and ty mean. What do these things mean and more importantly how do I find this out on my own in the future. I would like to rotate an object in a circle every frame.
There’s also the option of simply calling playdate.geometry.affineTransform.new() without any arguments, then calling :translate(…), :rotate(…), etc on it to perform the operation(s) you want.
