I have a function SendInstruction which send instructions to the user to press a button with label x for 3 seconds. I have four buttons with labels y,z and w.

fun SendInstruction(buttonLabel:String):String{
return buttonLabel
}

I have a counter that either increments by 20 if correct sent instruction matches user clicked button and decrements if not correct.

But when correct for 3 seconds then another instruction can be sent for button y otherwise user must pass button x to go to y and also must pass y to go to z and must pass z to go to w

Here is what i tried so far

var counter:Int = 0

GlobalScope.launch{
SendInstruction("click button x")
if(userclicked)//always true for 3 seconds
   delay(3000)//check in 3s if instructions matches user clicked
   counter +=20
   SendInstruction("click button y")
   if(userclicked)//always true for 3 s
      delay(3000)//check in 3s if instruction matches user clicked
else
   counter = 0
   //restart
}

But it just doesn’t work, can anyone help me with this please.
