#include <ButtonConstants.au3>

#include <NomadMemory.au3>
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Counter-Strike Health Trainer by ~>Kredar<~", 383, 81, 192, 124)
$Checkbox1 = GUICtrlCreateCheckbox("Health Inf.", 16, 8, 73, 17)
$Button1 = GUICtrlCreateButton("Start", 136, 0, 241, 33, 0)
$Button2 = GUICtrlCreateButton("Exit", 136, 40, 241, 33, 0)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
	$nMsg = GUIGetMsg()
	Switch $nMsg
		Case $GUI_EVENT_CLOSE
			Exit

Func _Hack(); This is the functions which turns on the hacks when you start S4 League.
	GUISetState(@SW_HIDE);
	ToolTip("Whait for CS...",0,0); This is up in the corner which says Start S4 League!
	$WAIT = ProcessWait("hl.exe"); Waiting For S4 League
	$PID = ProcessExists("hl.exe"); He found S4Client.exe
	Sleep(500);Takes a little break..
	$OPEN = _MemoryOpen ($PID); The memory .. which makes the functions work.
	If GUICtrlRead($Checkbox1) = 1 Then
		_MemoryWrite(0x00FE26EA,$OPEN,"0","Float");This is a float value. 
	EndIf
	If GUICtrlRead($Checkbox2) = 1 Then
		_MemoryWrite(0x00EF37A6,$OPEN,"0","char[2]"); This is a string..
		_MemoryWrite(0x00EF37D6,$OPEN,"0","char[2]"); This is another string with an other address.
		_MemoryWrite(0x00EF3806,$OPEN,"0","char[2]")
	EndIf
	Exit
EndFunc
