Circle(100,100,100,8)
WaitKey()

Function Circle(x,y,radius,corners)
	If corners = 0 Then Return 0 ;Check so that we don't divide by 0

	For i = 0 To corners
		Line radius*Sin(360/corners*i)+x,radius*Cos(360/corners*i)+y,radius*Sin(360/corners*(i+1))+x,radius*Cos(360/corners*(i+1))+y
	Next
End Function

oh, you mean a polygon with (x) Sides? Cool :)


CS_TBL2006
For completeness, since you divide by 'corners' .. better have a check on 'corners' being <>0 :P

@Cygnus: Not necessarily a polygon, if you change corners to 32 it becomes a circle.

@CS_TBL: Ok, forgot that.

If it's got any 'corners' at all, it's a polygon. 'polygon' means 'many sided'. A true circle doesn't have sides.
