Rotate around point

Rotate around x,y

Sometimes you just need to rotate around something else.

pretty please?

To rotate an object A degrees around point P:

Set 'distance' to distance(Object.X, Object.Y, P.X, P.Y)

Set 'angle' to angle(Object.X, Object.Y, P.X, P.Y)

Set X to P.X + cos(angle + A) * distance

Set Y to P.Y + sin(angle + A) * distance

Haven't checked that but I think it's right...

yea, pretty sure thats it. you can also use another sprite if it makes it any easier. make a 4x1 px sprite with the action point on one side, then put an image point on the other side. then set the object position to the image point and rotate the rotate-helper sprite. The distance is rotate-helper.width (just thought of this now, actually seems like a pretty useful idea ).
