Vindicator209 Posted April 29, 2008 Posted April 29, 2008 Well, I want to make a little auto-drawer for a game , and I want to make my cursor to move in a circle... I figure it had something to do with sine and cosine, but I don't know how to... can anyone help me =P?

qazwsx Posted April 29, 2008 Posted April 29, 2008 I would say it has to do with: x^2 + y^2 = r^2. Where r is the radius of the desired circle. Then just use a loop with mouse moves, and incrimentation of the x variable. If that didnt make any sense just ask and ill post some code.

If that didnt make any sense just ask and ill post some code.You could also use Cos() and Sin(), like this #include <GuiConstantsEx.au3> #include <GDIPlus.au3> Global $hGUI, $hWnd, $hGraphic,$x,$y Opt("GUIOnEventMode",1) ; Create GUI $hGUI = GUICreate("GDI+", 800, 500) $hWnd = WinGetHandle("GDI+") GUISetOnEvent(-3,"close") GUISetState() _GDIPlus_Startup() $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hWnd) Do Sleep(50) _GDIPlus_GraphicsFillEllipse($hGraphic, 100*Sin($x)+400, 100*Cos($y)+250, 70, 70) $x+=1 $y=$x Until 0 Func close() ; Clean up resources _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_Shutdown() Exit EndFunc Edited April 29, 2008 by monoceres Broken link? PM me and I'll send you the file!
