Creating a timer using Lua

Question

I would like to create a timer using Lua, in a way that I could specify a callback function to be triggered after X seconds have passed.

What would be the best way t

Answer 1

If milisecond accuracy is not needed, you could just go for a coroutine solution, which you resume periodically, like at the end of your main loop, Like this:

require 'socket' -- for having a sleep function ( could also use os.execute(sleep 10))
timer = function (time)
    local init = os.time()
    local diff=os.difftime(os.time(),init)
    while diff

This uses the sleep function in LuaSocket, you could use any other of the alternatives suggested on the Lua-users Wiki
