Hi,
I have a problem what I’m trying to do is make my fillRect() Rotate constantly as it moves around a point
What i mean by this is, I have wrote the trigonometry so the fillRect() moves around a point constantly and then what I am trying to do is make the shape rotate as it goes around the point any help would be apprecited
