Move your mouse to move Scratch cat! That's all you have to do, he does the rest. :)
These blocks allow you to convert x and y positions to direction and motion. Now that I think about it, it does sound quite like bitmap to vector, since X and Y coordinates is more or less what is used in the bitmap scheme, but velocity is a vector! By the way, a vector is something with both magnitude and direction. Thanks to trigonometry and the Pythagorean Theorem, I was able to make these new blocks. Enjoy!
