BillLuvsU Posted January 19, 2011 Share Posted January 19, 2011 (edited) Ok, so I recently start playing around with GDIPlus, with an explanation or two on the basic theory. How it was explained to me, was you load the correct background section into a bitmap, and then overlay the characters, items etc that you need and send the completed image to our graphics control. When playing around with the functions included in the autoit library however, it doesn't seem to quite work like that. Using the excellent mario game as a reference point. The only way i could see that made sense was constructing your frame on the graphics control. However, when I attempted to draw the background and the character directly on to my GUI, it causes a flashing effect (I'm assuming this is caused by real time lag between the two draw functions). So, if the lag between two draw functions is enough to cause a flash, I can't see extending the code making it any better. I saw somthing in the Mario code using _WinAPI_RedrawWindow but I'm not sure how that works in with the GDIPlus commands. My code is below, any help or ideas would be appreciated. expandcollapse popup;////////////////// INITIATION #include <GuiConstantsEx.au3> #include <GDIPlus.au3> #Include <Misc.au3> #include <WindowsConstants.au3> Dim $dll_user32 = DllOpen("user32.dll") Dim $x =300 Dim $y =300 Dim $speed = 5 ;////////////////// GUI CREATION ;Main GUI $h_GUI_main = GUICreate( "Battle of Destiny", 800, 600 ) GUISetState( ) ;Character $h_GUI_character = GUICreate("", 34, 47, 383, 277, $WS_CHILD, 0, $h_GUI_main ) GUISetState( ) _GDIPlus_Startup () ; Draw bitmap to GUI $hBitmap = _GDIPlus_BitmapCreateFromFile (@ScriptDir& "\Images\map_01.bmp") $h_link_ref = _GDIPlus_BitmapCreateFromFile (@ScriptDir& "\Images\characters\link.png") MsgBox(0,"",$hBitmap) Dim $h_graphic_main = _GDIPlus_GraphicsCreateFromHWND ($h_GUI_main) Dim $h_graphic_character = _GDIPlus_GraphicsCreateFromHWND ($h_GUI_character) Dim $hClone = _GDIPlus_BitmapCloneArea ($hBitmap, 0, 0, 800, 600, $GDIP_PXF24RGB) _GDIPlus_DrawImagePoints($h_graphic_main, $hClone, 0, 0, 800, 0, 0, 600) ;////////////////// MAIN LOOP $msg = 0 Dim $move = 0 While $msg <> $GUI_EVENT_CLOSE $msg = GUIGetMsg( ) $move = 0 If _IsPressed("25", $dll_user32) Then Left( ) If _IsPressed("26", $dll_user32) Then Up( ) If _IsPressed("27", $dll_user32) Then Right( ) If _IsPressed("28", $dll_user32) Then Down( ) $h_frame = _GDIPlus_BitmapCloneArea ($hBitmap, $x, $y, 800, 600, $GDIP_PXF24RGB) $h_hero = _GDIPlus_BitmapCloneArea ($h_link_ref, 0, 0, 34, 47, $GDIP_PXF24RGB) If $move = 1 Then _GDIPlus_GraphicsDrawImage($h_graphic_main, $h_frame, 0, 0) _GDIPlus_GraphicsDrawImage($h_graphic_character, $h_hero, 0, 0) ;Sleep ( 50) WEnd _GDIPlus_ShutDown () _GDIPlus_ImageDispose ($h_frame) _WinAPI_DeleteObject ($hBitmap) ;////////////////////// FUNCTIONS Func Right( ) $x = $x + $speed $move = 1 EndFunc Func Down( ) $y = $y + $speed $move = 1 EndFunc Func Up( ) $y = $y - $speed $move = 1 EndFunc Func Left( ) $x = $x - $speed $move = 1 EndFunc Edit: looking at my own code I remembered that I changed around how it works, I tried using a separate GUI to see If that would stop the flashing, but still no luck. Sorry for the crappy coding .
