   Sleep("50000")

WEnd



EndFunc
Soweit so gut, er f�hrt die einzelnen Punkte an. Erkennt auch ob die Passende Farbe in dem Bereich vorhanden ist.
Jetzt m�chte ich aber sagen, wenn diese Farbe dort nicht vorhanden ist, breche diese Funktion ab, und gehe in eine andere.

Wie kann ich dies mittels If abfrage realisieren?

You can follow the easy way:

Code:

$color1 = 0xB7E99B
$color2 = 0xFF5512

func start()

While 1
   MouseClick("left", 1282, 570, 1)
   Sleep(2500)
   MouseClick("left", 713, 718, 1)
   Sleep(1000)

   $array_pos = PixelSearch(840,769,1050,819,0xB7E99B,5)
   If Not @error Then
   MouseClick("left", $array_pos[0],$array_pos[1],1,0)
   Sleep(50000)
   Else
   ;Not found, do sth here, maybe another pixel search or sth
   ;Ex:
   ;$array_pos = PixelSearch(0,0,500,500,$color2,5)
   ;If Not @error Then
	;MsgBox(0,"Found","yay")
	;EndIf
   EndIf

WEnd

EndFunc

Advantages:
Easy to implement
Works most of the time

Cons:
Messy if/else concatenation when need to check a lot of events
Low maintainability

Or the event oriented one:

Code:



;This function register event handlers for pixelsearch, and the callback function

Global $handlers[0][3]
;Function,Callback,Disabled
Func registerSearchHandler($searchParams,$callbackFunction)
	ReDim $handlers[UBound($handlers)+1][3]
	$index = UBound($handlers)-1
	Local $newArray[UBound($searchParams)+1]
	$newArray[0] = "CallArgArray"
	For $i = 1 To UBound($searchParams)
	$newArray[$i] = $searchParams[$i-1]
	Next
	$handlers[$index][0] = $newArray
	$handlers[$index][1] = $callbackFunction
	$handlers[$index][2] = False
EndFunc


;Event handler functions, called when condition is met

Func handler1()
MsgBox(0,"handler1","pink found")
EndFunc

Func handler2()
MsgBox(0,"handler2","yellow found, disabling pink search")
$handlers[0][2] = True
EndFunc


Func handlern()
MsgBox(0,"handlerN","light blue found, enabling pink search")
$handlers[0][2] = False
EndFunc

;Register pixelsearch params, and event handler function

Local $arr = [0,160,555,300,0xFF00FF,5]
registerSearchHandler($arr,handler1)

Local $arr = [0,160,555,300,0xFFFF00,5]
registerSearchHandler($arr,handler2)

Local $arr = [0,160,555,300,0x00FFFF,5]
registerSearchHandler($arr,handlern)


While 1

;   MouseClick("left", 1282, 570, 1)
 ;  Sleep(2500)
 ;  MouseClick("left", 713, 718, 1)
 ;  Sleep(1000)

	For $i = 0 To UBound($handlers) -1
;if handler disabled, not execute 
		if($handlers[$i][2]) Then ContinueLoop
		$ret = Call("PixelSearch",$handlers[$i][0])
		If Not @error Then
			Call($handlers[$i][1])
		EndIf
	Next

	;Sleep(5000)

WEnd

Advantages:
Easy scalability
No messy code
Can change callbacks at any time

Cons:
Messy State machine, (if after some event, another should be disabled, then callback function should handle this manually)...
Hard to implement and understand
