##Just a bit of math neccessary for rotating the arrow correctly. Renpy did not want to cooperate.

##This is what actually spins the image. It works essentially the same as renpy's rotate function, except here I can change the origin location.
##That is neccessary because Renpy will not allow me to change the center of the image (and actually use that as a center).
##We're also going to casually ignore the fact that the number 187 is not based on any kind of math, and is just a random number that seems to place things right.
##I wasn't that good at math in school, so I can't explain that.

##Actual screen that has the thing on it, passes the behaviour number to the rotating function.
