Use the up arrow or the W key to move forward. Right/Left arrow and A key and D key are used to rotate. Take a look at the code and see how the "move __ steps" works!
I made this because I haven't made anything in awhile. This idea can be useful if you are trying to do an acceleration formula or something of the sort. If you are confused on why this works, and maybe have a little bit of trig knowledge, I found a video that explains it pretty well: https://www.youtube.com/watch?v=yIebSnsTGPE
