Multiplayer Game Help

I am making a gmae for Noodle-SH but I need help for multiplayer.
I have a sprite which is "o" (soon to be changed).

I need to be able to draw a new sprite when someone connects to an ID of the computer.
Example:

term.clear()
term.setCursorPos(1,1)
local currentX = 25
local currentY = 9
local sprite = "o"
write "Type the id you would like to join: "
local c = read()

-- Now for the movements
if event == key and key == "w" -- ik.. the id's, but im at school
currentY = currentY - 1
rednet.send(c, "up")
end

-- Receive code
id, msg = rednet.receive()
if id == c and msg == "up" then -- THE C IS ALSO ON THE OTHER COMPUTER TO JOIN SOMEONE ELSE IP - IP (Connecting)
(OtherOBJECT) currentY = (OtherOBJECT) currentY - 1
end

Nvm fixed xD
When event: Join - Happens it makes new sprite at the spawn location.

Hmm.. Can anyone help with
loading a sprite?
sprite2.currentx ??

Instead of doing rednet.recieve
Try:

if event == "rednet_messege" then

To recieve and move at the same time

Where to put this?
