Coroutine Tutorial by xLegox

Have you ever wanted to make your script do soemthing like run to separate for loops at the same time, or wait for a while in on function, why still doing things? Well here's how!

I will explain here how to use the coroutine.create() and coroutine.resume()

First off, coroutine.create, creates a "thread" object. This "thread" prerforms a talsk such as the script that called it does, but it starts this taks, without stopping the current operations of the thread, it make s the 'thread''s actions happen simotaniously to the current ones in the script... here's and example.

local a = true

function run()
while a == true do
print("Going...")
wait(1)
end
end

local myCoroutine = coroutine.create(run)
coroutine.resume(myCoroutine)
wait(20)
a = false
print("Gone!")

What does this do?

first, the function "run" continualy prints "going..." untill a is false

now, loom at the line "myCoroutine = coroutine.create(run)"

this creates an object, of the type "thread", which we taged "myCoroutine"

it has the function "run" as it's body

next we have the "coroutine.resume(myCoroutine)" line

this tells the script to start playing the body of the thread, myCoroutine

next the script starts waiting, and the function "run" will continualy run while the script waits

then the script makes the variable "a" false to stop the coroutine.

and then prints "gone!"

in effect it should print...

Going...
Going...
[...]
Going...
Gone!

Hope that helps some more advanced scripters out with problems running multiple things at once =P

Ok, cool. To bad I'm not that advanced... XD Though, I just thought of using multiple scripts with the Wait() function timed..

I don't really like the coroutines, I'd rather just call the functions, what situation would make you NEED to call a coroutine?

I was thinking of using coroutine in a minigame arena. You could have the coroutine monitoring who is still playing vs. who left while running the actual game with the rest of the script.

Yes, ever heard of a try-catch sequence? It's often used in C++ work. Coroutines are handy for catching errors and fixing them. A minigame loop combined with coroutines is very handy.
