-- now we have drawn our buttons we should set
-- the text background colour back to black


-- Now we need to check if the button is clicked

-- First we are going to create a function called
-- checkClickPosition(). A function will not run
-- until you ask for it.

-- We know the first button starts at 2 from the
-- top and 2 from the left. We also know it is 5
-- spaces long. This means the button ends
-- at width 7

-- We will be told which width and
-- height the click happened at.
-- If the width position is greater than 1 AND
-- less than 8 we have clicked somewhere between
-- 2 and 7.

-- If this is true we can then check the height
-- position. Button one is at height 2 and button
-- two is at height 4.

-- This means that if the width is greater than 1
-- AND the width is less than 8 AND the height
-- equals 2 we have clicked button 1

-- If the the width is greater than 1 AND the width
-- is less than 8 AND the height equals 4 we have
-- clicked button 2

-- now to write this as a function
-- Functions are written like this

--     function exampleFunction()
--       print("Hello")
--       sleep(10)
--       print("Goodbye")
--     end

-- Now when you write exampleFunction() the program
-- will print hello, sleep for 10 ticks and then
-- print Goodbye.
-- This is useful for making your programs easier
-- to understand

function checkClickPosition()
  if mouseWidth > 1 and mouseWidth < 8 and mouseHeight == 2 then
        rs.setBundledOutput("top", colors.white)

  elseif mouseWidth > 1 and mouseWidth < 8 and mouseHeight == 4 then
        rs.setBundledOutput("top", colors.black)

  end -- ends the if loop
end -- ends the function

function checkClickPosition()
  if mouseWidth > 1 and mouseWidth < 8 and mouseHeight == 7 then
        rs.setBundledOutput("top", colors.blue)

  elseif mouseWidth > 1 and mouseWidth < 8 and mouseHeight == 9 then
        rs.setBundledOutput("top", colors.black)

  end -- ends the if loop
end -- ends the function

-- this function does nothing until you write
-- checkClickPostion(). We will be doing this below
-- It then checks the click position and turns the
-- lamp on if button one is clicked or turns the
-- lamp off if button two is clicked

-- OK. Now we need to check if a click happens
-- we will use a repeat-until loop.
-- In the loop we we use a os.pullEvent().
-- an os.pullEvent() gives you different info
-- depending on the event type. We will mainly
-- check the "monitor_touch" event.

-- In the second line you will see
-- event,p1,p2,p3 = os.pullEvent()
-- if the event is a click on the monitor it
-- will give us 4 bits of info:
--    event will be "monitor_touch"
--    p1 will be the side the monitor is on (top)
--    p2 is the width postion of the click
--    p3 is the height postition of the click



repeat
-- repeat runs a loop of code.

  event,p1,p2,p3 = os.pullEvent()
  -- this line tells the computer to wait until
  -- an event happens. We are waiting for a
  -- touchscreen event

   if event=="monitor_touch" then
   -- this checks to see if the event was a
   -- touchscreen event

     mouseWidth = p2 -- sets mouseWidth
     mouseHeight = p3 -- and mouseHeight
     checkClickPosition() -- this runs our function

   end
   -- the end of the "if loop".


until event=="char" and p1==("x")
-- this is the end of the "repeat loop". This will
-- stop the repeat loop if a "char" event happens
-- A char event means you press a character on
-- the keyboard. This line is looking for the x key
