How to get a imput from the keyboard whyle a program is running

[Vexxen1]

I have a whyle loop. I want to do something when the person presses "k", then once then press k it will pause the whyle loop, and open a menu where they can imput in things. But when k is not pressed i still want it to run the entire whyle loop.

So i need:

1. How to get a bollene value of when a key is pressed without waiting for it to be pressed
2. How to wait for imput from the terminal. Like wait for a y/n.

So the easiest thing to do here is use the parallel API to pull the key event while your main loop is running. So something like

local running = true
parallel.waitForAll(function()
 while running do 
   -- ... 
  end 
end, function()
  while true do 
    local event, key = os.pullEvent("key")
    if key == keys.k then running = false end 
  end 
end)
