I'd like to know what I can improve.

Thanks in advance

1) post more code to get more help

2) use GUIRegisterMsg & WM_PAINT

3) use _GetDC() to simplify it

3)

_GDIPlus_Startup()
$hGui = GUICreate("Spawn Map", $guiWidth, $guiHeight, -1, -1, 0x80000000, 0)
GUISetBkColor(0xFF000000, $hGui)

$hDC = _WinAPI_GetDC($hGui)

;~ $gdig = _GDIPlus_GraphicsCreateFromHWND($hGui)
;~ $hbitmap = _GDIPlus_BitmapCreateFromGraphics(1240, 720, $gdig)
;~ $hDC = _GDIPlus_ImageGetGraphicsContext($hbitmap)

GUISetState()

$hpen = _GDIPlus_PenCreate(0x000000, 4)
$drawx = Floor(($xx[$cnt]) / 32)
$drawy = Floor(($yy[$cnt]) / 45.5)
_GDIPlus_GraphicsDrawLine($hDC, $drawx - 1, $drawy, $drawx + 1, $drawy, $hpen)
_GDIPlus_GraphicsDrawLine($hDC, $drawx, $drawy - 1, $drawx, $drawy + 1, $hpen)

_GDIPLUS_GRAPHICSDRAWIMAGE($gdig, $hbitmap, 0, 0)

Look at Radar project in my signature - function MalujKriz() it means DrawCross() over picture

Also look at BlackJack on the forum how to optimize drawing stuff with memory bitmap - antiflicker

I can't use_GetDC() to simplify it, or it crashes : /

And anyway I need 2 handles one to write on the other, or else I can't re-calculated stuff during the program execution and add it to the image, can I ?

Edit: modified source to match actual state of dev and a pic for those wondering what It looks like when it's running...

You can prepare memory bitmap and then use BitBlt API to quickly paint it over whatever on the screen.

Hi,

Ways to improve your script:

Use formating to make the script easier to follow.

Indenting lines can make things more easier to read and follow.

If it's easier to read and follow, yourself and others may actually spot problems or potential problems easier.

ATM it's a blur of loops and functions and it's just not easy to see where what starts and ends.

I think it's only fair if your going to ask how to improve your code make it at least easy readable by the average person.

Try using includes instead of evil magic numbers when possible while writing your script.

After you have your script where you want it then thin it down and speed it up using evil magic numbers if you need to.

Atm the code you've supplied does not work for me without trying to follow what your code is doing and debugging where it fails.

As for repainting the screen then store the drawn points and data in a variable/array and then loop the stored points/data with appropriate brushes/pens/etc in the WM_PAINT function.

Cheers

Zedna · May 22, 2008

Call GUIRegisterMsg() only once at start and not in Loop

eleria · May 23, 2008

I\'ve post my code in autoit beacons, now it looks much better!

$memDC = _WinAPI_CreatecompatibleDC($hGui)

$memBmp = _WinAPI_CreateCompatibleBitmap($memDC, $guiWidth, $guiHeight)

Gives me an error o_O, and

$hDC = _WinAPI_GetDC($hGui)

$memDC = _WinAPI_CreatecompatibleDC($hDC)

$memBmp = _WinAPI_CreateCompatibleBitmap($memDC, $guiWidth, $guiHeight)

Completely crashes the application
