Event.listen handling

[north 0]

Is there a way to get event data when using event.listen()?

I'm trying to display "X" where the user touches the screen. It works with event.pull() as I can get all the necessary parameters to pass to the GPU component, however, this yields the computer.

while true do
   local _, _, x, y = event.pull("touch")

   gpu.set(x, y, "X")
end

Is there a way to do this in the background using event.listen()? Something along the lines of
 

event.listen("touch", mark)


function mark(e) --e being the event that was registered
   _, _, x, y = e
   gpu.set(x, y, "X")
end

After some tinkering, it seems I wasn't far off. Here's the way to do this if anyone was dealing with something similar.

 

event.listen("touch", mark)


function mark(_, _, x, y)
   gpu.set(x, y, "X")
end

Mod Edit: When using event.listen() the function you call in the 2nd parameter gets passes the data as arguments to it. Specifically, touch has the following arguments event: string, screenAddress: string, x: number, y: number, button: number, playerName: string.
