retx = (radius * floatcos(angle, degrees) + x);
rety = (radius * floatsin(angle, degrees) + y);

I think you need do this:

Code:

retx = (radius * floatsin(-angle, degrees) + x);
rety = (radius * floatcos(-angle, degrees) + y);

I realy don't know why thease minuses before angles needs, but without them this won't work perfect.

P.S. sorry for my english if I did mistakes on writing.
