How do you refresh a function until it passes?

[shea851]

I want to call a function that checks for a pixel color indefinitly until it's not that color. How can I make a function "refresh" or go to the beginning of itself?

Func checkCast()
 If (PixelGetColor($x, $y) = $color) Then
  Sleep(500)
  checkCast();can a function call itself inside itself? i dont think so? how do i do this part?
 Else
  Sleep(10)
 EndIf
EndFunc

Do
$i = CheckCast()
Until $i = 1

Func checkCast()
If (PixelGetColor($x, $y) = $color) Then
  Sleep(500); pixels are same color
  Return 0
Else
  Sleep(10);pixel is different color
  Return 1
EndIf
EndFunc
