You use the degree when you are first naming any constant. If you are going to use it as a variable elsewhere you no longer need the degree when using it. On the other hand, if you are using the named constant for its value, then you always need the degree.

Its more like a little note to the compiler that tells it to replace that named constant with the value you assigned it.

So for my game I need to invert pixels on a sprite based on a what pixels are on. I tried pointe change but It didn’t seem too work.
