Self in Lua

Declaring a function as t:test instead than t.test will automatically set a variable named self that refers to t. If that is a table, it’ll be possible to use self.a to refer to the value of object a in table t (like table = {a=1})

Coroutines

• coroutine.create(f) = where f is a function
• coroutine.resume(c, [ares]) = resume a coroutine, optionally passing an argument
• coroutine.running() = to obtain a reference to the currently running coroutine
• coroutine.status(c) = returns strings “running”, “suspended”, “normal”, “dead” according to the status of the coroutine
• coroutine.yield(...) = suspends the current coroutine and returns its arguments
• coroutine.wrap(f) = wrap a normal function so it can be used like coroutine.yield() on it, like it were a coroutine
