How do i stop AHK loop when LButton is up - autohotkey

Question

I just want this loop to work when LButton is down and stop when LButton is up.I
The code works when LButton is down but it continues working when i lift my finger off the left click button.
mem:=0
~*LButton::
Sleep, 100
KeyWait, LButton, T0.10
If ErrorLevel = 1
{
While GetKeyState("LButton","P")
Loop {
GetKeyState, state, LButton, P
If state = U
Break
MouseGetPos, xpos, ypos
if (xpos > mem) ;moved right
{
send, {a down} ;send key
mem:=xpos
}
else
send, {a up}
if (xpos < mem) ;moved left
{
send, {d down}
mem:=xpos
}
else
send, {d up}
Sleep, 100
}
}
return

You case is very similar to the example of the usage of the while loop.
If you look at that you can see, you don't need the Loop inside the while. Just have
while GetKeyState("LButton")
{
; Your code here:
MouseGetPos, xpos, ypos
if (xpos > mem) ;moved right
{
send, {a down} ;send key
mem:=xpos
}
else{
send, {a up}
}
if (xpos < mem) ;moved left
{
send, {d down}
mem:=xpos
}
else{
send, {d up}
}
Sleep, 100
}
