circle move towards mouse - GDIplus

[Alex1986]

Hi

I have a problem in making  circle2 moving toward the mouse, and is adjacent to circle1

this example , but this not move toward  mouse

expandcollapse popup

#include <GDIplus.au3>
#include <GUIConstantsEx.au3>

AutoItSetOption("MouseCoordMode", 0)
AutoItSetOption("GUIOnEventMode", 1)

Global Const $iW = 400, $iH = 400, $iBgColor = 0xF0F0F0
Global Const $hGUI = GUICreate("", $iW, $iH)
GUISetBkColor($iBgColor, $hGUI)
GUISetState()

_GDIPlus_Startup()
$hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
$hPen = _GDIPlus_PenCreate()
$hPen2 = _GDIPlus_PenCreate(0xFFFF0000, 2)
$hBitmap = _GDIPlus_BitmapCreateFromScan0($iW, $iH)
$hCtxt = _GDIPlus_ImageGetGraphicsContext($hBitmap)
_GDIPlus_GraphicsSetSmoothingMode($hCtxt, 4)
_GDIPlus_GraphicsSetPixelOffsetMode($hCtxt, 4)

Global Const $iPosX = 50, $iPosY = 50, $iWidth = 300, $iHeight = 300
Global $iMPosX, $iMPosY
Local Const $fDeg = ACos(-1) / 180, $iRadius = 30.6, $iRadius2 = $iWidth / 2 , $iWh1 = $iW / 2, $iHh1 = $iH / 2
Local $fAngle = 0 , $fAngle2 = 155 , $fAngle3 =333, $i = 0

GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")

Do
    _GDIPlus_GraphicsClear($hCtxt, 0xFF000000 + $iBgColor)
    _GDIPlus_GraphicsDrawRect($hCtxt, $iPosX, $iPosY, $iWidth, $iHeight, $hPen)
    $hPos = GUIGetCursorInfo($hGUI)

    ; circle1
    _GDIPlus_GraphicsDrawEllipse($hCtxt , $iWh1 - 15, $iHh1 - 15, 30 , 30 , $hPen)

    ; circle2
    $X1 = $iWh1 - 15 + Cos($fAngle * $fDeg) * $iRadius
    $X2 = $iHh1 - 15 + Sin($fAngle * $fDeg) * $iRadius
    _GDIPlus_GraphicsDrawEllipse($hCtxt , $X1 , $X2 , 30 , 30 , $hPen)

    $fAngle += 1
    if $fAngle = 360 Then
        $fAngle = 0
    EndIf

    _GDIPlus_GraphicsDrawImageRect($hGraphic, $hBitmap, 0, 0, $iW, $iH)
Until Not Sleep(10)

Func _Exit()
    _GDIPlus_GraphicsDispose($hGraphic)
    _GDIPlus_GraphicsDispose($hCtxt)
    _GDIPlus_BitmapDispose($hBitmap)
    _GDIPlus_PenDispose($hPen)
    _GDIPlus_PenDispose($hPen2)
    _GDIPlus_Shutdown()
    GUIDelete()
    Exit
EndFunc

Like this?

$hPos = GUIGetCursorInfo($hGUI)
    If (Not @Error) Then
        If ($hPos[0] > $iWidth + $iPosX - 15) Then $hPos[0] = $iWidth + $iPosX - 15
        If ($hPos[0] < $iPosX + 15) Then $hPos[0] = $iPosX + 15
        If ($hPos[1] > $iHeight + $iPosY - 15) Then $hPos[1] = $iHeight + $iPosY - 15
        If ($hPos[1] < $iPosY + 15) Then $hPos[1] = $iPosY + 15
        $iWh1 = $hPos[0]
        $iHh1 = $hPos[1]
    EndIf

not like that , thank you
* I need to be moving circle2 which is adjacent to Circle1 and  heading towards mouse cursor

Try this:

#include <GUIConstantsEx.au3>

AutoItSetOption("MouseCoordMode", 2)

    $fDistance = $fRadius2 + $fRadius1 ;calculate the distance between both circles so that they always touch each other

    ;calculate x/y position of 2nd circle with a little adjustment
    $X1 = $iWh - $fRadius2 + Cos($fAngle * $fDeg) * ($fDistance + 0.5)
    $Y1 = $iHh - $fRadius2 + Sin($fAngle * $fDeg) * ($fDistance + 0.5)

    _GDIPlus_GraphicsDrawEllipse($hCtxt , $X1 + $fRadius2, $Y1 + $fRadius2, 1, 1, $hPen2) ;center of circle 2

    _GDIPlus_GraphicsDrawEllipse($hCtxt , $X1 , $Y1 , $fDiameter2 , $fDiameter2 , $hPen2) ;circle 2

    _GDIPlus_GraphicsDrawImageRect($hGraphic, $hBitmap, 0, 0, $iW, $iH)

added some comments and shortened code

[Alex1986]

thank you UEZ , this is Great

Q : How to get the center of the circle2 , It moves with the mouse cursor ?

 

 

[AutoBert]

MouseGetPos is the magic func.
