you use cos for the x position and sin for the right. Say you wanted particles coming out of a fixed rotation point, with no lag or weird offset, you would do 30*cos(self.rotation) and 30*sin(self.rotation) in the x and y emiiter offset for the particles

Its basic trig, search google and math websites and the forums for a full detailed explanation on how it works and what else you can do
