This was a fun little test to see if the sine and cosine of a variable can draw a circle! ...You can see inside to see what I mean. Press space to hide/show the red and blue dots, and drag around the center dot to see what happens!
So this is a much more consistent way to draw a circle than using direction or something of the sort, I may implement this in a future game on my main account, @thepixel2000.
