Racing Game in AutoIt

[newbiescripter]

Hello

I was trying to make a little Race game in AutoIt. It's very basic and doesn't works so well, so now I post it in hope that some of you might have some keywords to help me muttley

As you can see when you run it. it doesn't work so well because it's also refreshing the track which is very big..

hmm.. I've tried to use GUICtrlSetPos, but it seems that it doesn't work with graphic since I still need to refresh before seeing that it has been moved.

then I tried to create another cirkel object (the car) with GDI+ ellipse, but it didn't work either..

I know that I could load an image as the background and use an icon or something as the car, but I was trying to make it all in AutoIt.

Maybe some of you have some nice ideas that I can work on with..

Regards

Hi newbiescripter,

Have you had a chance to look into prospeed for autoit? It allows you to create sprites and move/refresh them quickly. Do a search in the forums to find it.

Hi!

Drawing sprites in GDI+ that moves around on a background is fairly simple.

I made some sample code for you to study.

expandcollapse popup

#include <GDIPlus.au3>
#include <WinAPI.au3>
#include <misc.au3>
; Create GUI..blabla
Opt("GUIOnEventMode",1)
$hwnd=GUICreate("Sample",300,300)
GUISetState()
GUISetOnEvent(-3,"close")

_GDIPlus_Startup()
$graphics=_GDIPlus_GraphicsCreateFromHWND($hwnd); This graphic object gives access to the drawing area of the GUI
$backgroundbitmap=_GDIPlus_BitmapCreateFromGraphics(300,300,$graphics); Create a bitmap in memory, this will be our background
$backgroundgraphics=_GDIPlus_ImageGetGraphicsContext($backgroundbitmap); We can access the background bitmap with this
$backbufferbitmap=_GDIPlus_BitmapCreateFromGraphics(300,300,$graphics); Create a bitmap in memory, this will be our temporary buffer
$backbuffergraphics=_GDIPlus_ImageGetGraphicsContext($backbufferbitmap); We can access the backbuffer with this

$whitebrush=_GDIPlus_BrushCreateSolid(0xFFFFFFFF)
$greenbrush=_GDIPlus_BrushCreateSolid(0xFF00FF00)
; Let's draw our background
_GDIPlus_GraphicsFillRect($backgroundgraphics,25,25,250,250,$whitebrush)

Dim $x,$y
Do
; Clear the backbuffer and draw the background on it
    _GDIPlus_GraphicsClear($backbuffergraphics,0xFF000000)
    _GDIPlus_GraphicsDrawImageRect($backbuffergraphics,$backgroundbitmap,0,0,300,300)
    
; move the dot
    If _IsPressed("25") Then
        $x-=3
    EndIf
    If _IsPressed("26") Then
        $y-=3
    EndIf
    If _IsPressed("27") Then
        $x+=3
    EndIf
    If _IsPressed("28") Then
        $y+=3
    EndIf
    
    
; Draw the action;)
    _GDIPlus_GraphicsFillEllipse($backbuffergraphics,$x,$y,10,10,$greenbrush)
    
    
; We're done drawing, let's show the user the result!
    _GDIPlus_GraphicsDrawImageRect($graphics,$backbufferbitmap,0,0,300,300)
    Sleep(20)
Until False






Func close()
    _GDIPlus_BrushDispose($whitebrush)
    _GDIPlus_BrushDispose($greenbrush)
    _GDIPlus_GraphicsDispose($graphics)
    _GDIPlus_GraphicsDispose($backbuffergraphics)
    _GDIPlus_GraphicsDispose($backgroundgraphics)
    _WinAPI_DeleteObject($backbufferbitmap)
    _WinAPI_DeleteObject($backgroundbitmap)
    _GDIPlus_Shutdown()
    Exit
EndFunc

Just ask if there is some part you don't understand.
