HyperSnapDX has a special function for capturing the mouse cursor only. I'd like to be able to do the same with AutoIt. Many users have asked how to get the pixel values of the mouse cursor. I guess one way to do it is to have an external program for the moment, but it is really somethig I wanna do with AutoIt.

Are you refering to needing something like the existing MouseGetPos() ?

i think he means getting the color of the mouse pointer.

I wanna get the colors of the mouse cursor. For instance in many games the ID of the mouse cursor is usually 0 (unknown) and changes of the mouse cursor in the game do not change the ID. So I need to read out the mouse cursor's color. One workaround I had was to use something like HyperSnap DX to grab a picture of the mouse cursor, then check the bytes of that file to detect differences and thus know which it is. If HyperSnap DX can capture the mouse cursor (and it is only the cursor it captures) out of games, then AutoIt can do it too (soon) I hope.

Something like MousePixelSearch() would seem an appropriate name (to do a pixelsearch on the mouse x-hair).

Note: I have actually no idea how easy/hard it is to implement. Common sense would say that if this was easy, they would have added it to v3 by now. So maybe it is hard?

Will this UDF do?

Opt("MouseCoordMode", 1)
Func _getMousePointPixelColor()
     Local $pos = MouseGetPos ( )
     Return PixelGetColor ( $pos[0] , $pos[1] )
EndFunc

Returns a decimal value of the pixel color of the mouse tip.

it gets the value from UNDER the mouse (atleast thats what im told)

Tried this also with AutoIt, but couldnt find a proven way of doing it.

Wrote a little c++ routine which grabs the BitMap of the actual cursor and does a unique checksum on it. As it uses GetBitMapBits its extremely fast as well. Works only for colored cursors (games) at the moment.

Is that the kind of function you are looking for ?

I Windows it would, but what about in a full-screen game where, as far as AutoIt knows, the cursor is rendered as part of the image on the screen?

Good question, but the cursor bitmap is still separate, so you wont get the Cursor pixel that way.

Just tested it with an Online RPG to be 100% sure.

@Noobie no , its not hard to implement, the checksum thingy is actually 12 lines of code only.
But it probably wasnt implemented a long time ago, as AutoIt is not intended mainly for the Gamers scene I guess.

I spend some time to try and do the same. I managed to get it to work, but I got stuck after I got a handler for the cursor. I was about to try to turn the handler into a pointer and getting the data from there, but then I realised I actually could detect a cursor change with the handler, so I was happy anyway. That was untill I realised that the game has 3 cursors. hehe. After that I went to look into some online code repositories & MSDN. I found some code, but they all stopped after getting the handle

Would love to see your code. This is the code I got now (which works for the game, but I wanna get the data from the handle).

No problem, as I said the code is quite straight forward. As with most BITMAP handling the solution is quite obvious once you found out how

//-------------------------------------------------------
//---   GetCursorID: get unique Cursor ID (proprietary)
//-------------------------------------------------------
int GetCursorID( )
{   // get the cursor, return if no handle
    CURSORINFO cCursor;
    ZeroMemory(&cCursor,sizeof(cCursor));
    cCursor.cbSize=sizeof( cCursor );
    if (!GetCursorInfo(&cCursor)) return 0;

    // get the icon, return if no color icon
    ICONINFO cIcon;
    if (!GetIconInfo((HICON)(cCursor.hCursor),&cIcon))return 0;
    if (!(cIcon.hbmColor)) return 0;

    // get the color icon bits, return if not 32x32 , 32bit/pixel
    BYTE lpColor[32*32*8];
    if (!( ::GetBitmapBits( cIcon.hbmColor ,32*32*8,lpColor)==4096)) return 0;

    // do a checksum of scanline 15

    int i1= 32*15*4;    
    for (int i=0;i<32*4;++i){cs += lpColor[i1+i];}
    return cs;
}

Please note that I just did a checksum of scanline 15 of the actual cursor to identify it instead of a proper alder checksum. This would get rid of the 32x32, 4bytes/pixel limitation for the cursor as well.

Hope it helps ...

That's fantastic! Thanks a zillion times!!!

Well it took me all night to figure how to do it, but finally I've created a DLL which wraps your function. This should make it easier for people to plug into their scripts...

Using this script make my program working very nice. But It stop working after sometime. I dun know why. Plz help me

Working nice about 5mins. After that, mouse still moving without click ( seem dllcall not working, cant check Mouse ID)

I've got the same problem. Maybe you should integrate a timer that restarts the script every 5 minutes.

typedef struct {

DWORD flags;
HCURSOR hCursor;
POINT ptScreenPos;
} CURSORINFO, *PCURSORINFO, *LPCURSORINFO;

struct = DllStructCreate("dword;dword;hwnd;long;long")
DllStructSetData($struct,1, DllStructGetSize($struct))

$return = DllCall("user32.dll", "int", "GetCursorInfo", "ptr", DllStructGetPtr($struct))
If $return[0] = 0 Then
    MsgBox(48,'Error','Error code = ' & $return[0])
Else    
    MsgBox(0,'Info','Flag = ' & DllStructGetData($struct,2) & @CRLF & 'Handle = ' & DllStructGetData($struct,3) & @CRLF & _
        'Pos.X = ' & DllStructGetData($struct,4) & @CRLF & 'Pos.Y = ' & DllStructGetData($struct,5) )
EndIf

$struct = 0

Yeah, the DLL is buggy unfortunately. When I find time I will try to make a more reliable version (can't see that happening any time soon).

If you would like to do this your self, you'll need a compiler that can build DLL's. I used Visual Studio 6, then found some tutorials on how to make a simple DLL that just returns a number and make a simple script that can talk to the DLL for testing purposes. After much trial and error I managed to produce this. You could achieve the same thing if you have a basic programming background, some Google skills and a free day to sit down and mess about with it. Debugging memory leaks in C is another thing entirely, but at least knowing how to build the DLL will be a good start.
