Executing a coroutine

To execute a coroutine, use the function coroutine.resume:

   coroutine.resume(<coroutine>)

You can also pass parameters to the coroutine function as additional arguments to the coroutine.resume function:

   local nt = coroutine.create(function(x, y, z)        print(x,y,z)    end)      coroutine.resume(nt, 1, 2, 3)

The output will be as follows:

   1,2,3

There is a function named coroutine.wrap that can replace the need of running coroutine.create and coroutine.resume. The only difference is that the coroutine must be assigned to a function:

local ntwrapped = coroutine.wrap(function()     print("w00t!") end)  ntwrapped() --Will print w00t!
