How do i use pixel search?

[FrozenScriptz]

How do i use pixel search???, the autoit help file is not explaining it well, this is the code autoit help was saying

PixelSearch ( left, top, right, bottom, color [, shade-variation [, step [, hwnd]]] )

and now I'm really confused what that is, left top right bottom? i don't understand, but i understand the colour,its like 0xFF0000(which is pure red) so can someone please help me?

I know that left is a coordinate of a rectangle and same for the others, but i just don't get it.

say you want to search an area of your screen from the top left corner, 50 pixels across and 50 pixels down for red.

$aResult = PixelSearch(0,0,50,50,0xFF0000)

Returns an array of coroordinates to the pixel if it finds one.

Well I'm Confused.

[JohnOne]

With what?

$aResult[0] contains the x coord

$aResult[1] contains the y coord

[FrozenScriptz]

Okay so is this like this?

$frozen = PixelSearch(0, 326, 0, 317, 0xFF0000)

I am so confused right now

you said that 0, 0 is the X coordinates and 50, 50 is the Y Coordinates.

I just dont get it.

Please explain it better so i can understand, I am really confused right now.

Left = the x top left of the rectangle to search starting position

Top = the y top left of the rectangle to search starting position

Right = the x bottom right of the rectangle to search starting position

Bottom = the y bottom right of the rectangle to search starting position

If you run this example, it should help you understand the screen coordinate system and the window or client coordinate system being used.

Move the cursor, and try to understand why the "x" and "y" values, (coordinates), change the way they do change.

Press Esc to exit.

#include <WinAPI.au3>

Opt("MouseCoordMode", 1) ;1=absolute, 0=relative, 2=client
HotKeySet("{ESC}", "Terminate")

Local $exit = 1

While $exit
    Sleep(10)
    TtColXY()
WEnd

; TtColXY() Tooltip shows colour, and cursor position relative to screen and window.
Func TtColXY()
    $aPos = MouseGetPos()
    Local $tPosS = _WinAPI_GetMousePos() ; similar to MouseGetPos() ;Screen mouse position
    $hHwnd = _WinAPI_WindowFromPoint($tPosS)
    Local $tPosC = _WinAPI_GetMousePos(True, $hHwnd)
    $sColor = "0x" & Hex(PixelGetColor(DllStructGetData($tPosS, "X"), DllStructGetData($tPosS, "Y")), 6)
    $iPosX = ($aPos[0] - 100) * ($aPos[0] > @DesktopWidth * 0.90) + ($aPos[0] <= @DesktopWidth * 0.90) * ($aPos[0] + 3)
    $iPosY = ($aPos[1] - 30) * ($aPos[1] > @DesktopHeight * 0.96) + ($aPos[1] <= @DesktopHeight * 0.96) * ($aPos[1] + 3)
    ToolTip("Color is: " & $sColor & @CRLF & "Screen: X: " & DllStructGetData($tPosS, "X") & " Y: " & DllStructGetData($tPosS, "Y") & @CRLF _
         & "Client: X: " & DllStructGetData($tPosC, "X") & " Y: " & DllStructGetData($tPosC, "Y"), $iPosX, $iPosY)
    Return
EndFunc ;==>TtColXY

Func Terminate()
    $exit = 0
EndFunc ;==>Terminate

So Those coordinates are the coordinates of a rectangle.

But please tell me how to find the coordinates of a file i want to find

can you please make the code,I really want to make game bots.
