Help with touch and printing out its results.

[BloodyRum 0]

I'm trying to get a little program set up to out the cords of the screen pixels when I click them. I looked around but still could not find one. One that I did find on Open-computers forum did not work. Here is my code.

function touchsig(_, x, y, _, _)
  print("Xcord: " .. x .. "Ycord: " .. y)
end
while true do
  event.listen("touch", touchsig)
end

Whenever I run it I get.

/cords:5: attempt to index global 'event' (a nil value)
stack traceback:\
        /cords:5: in main chunk
        (...tail calls...)

Any Ideas on how to fix this?

 

Also off topic but I'm doing this because I want to make a "spiffy" Big Reactors controller. Should I use OpenComputers like I planned or just settle with the OP Computercraft?

still not correct, you only have to call event.listen("touch",touchsig) once.

local event = require("event")

function touchsig(_, x, y, _, _)
print("Xcord: " .. x .. "Ycord: " .. y)
end

event.listen("touch", touchsig)

while true do
   os.sleep(1)
end

You have to import/require the event library.

local event = require("event")

function touchsig(_, x, y, _, _)
  print("Xcord: " .. x .. "Ycord: " .. y)
end

while true do
  event.listen("touch", touchsig)
end
