PostSubject: Coroutines and you   August 1st 2010, 2:50 pm

there are a few commands you need to know for coroutines:
coroutine.create -- makes a coroutine
coroutine.resume -- resumes a coroutine
corouinte.yield -- yields a coroutine

pretty obvious commands? My favorite way to use a coroutine is like this:
Code:
corutine.resume(coroutine.create(function() wait(1) print("I is a coroutine!")
end))
while wait(1) do
print("I is a loop!")
Oddly enough, create went after resume. Why? because otherwise it wouldn't have activated. Use this script in studio to see how the two loops work side by side without issue.

The while true do loop has no end and therefore will error.

Eh, no. You can use log files, xpcall, test servers, et cetera, for debugging. Coroutines are not really one of them. Though, coroutine.yield is REALLY useful for making a wait function that doesn't cross a Lua/C boundry and error in a(n) (x)pcall

I'm kinda new to corutines. Would this print 1, 2, 3, 4, 5, coroutine yielded?
Code:

x = 0
cor = coroutine.create(function() for i = 1, 100 do x = x + 1 print(x) wait(0.2) end end)
coroutine.resume(cor)
wait(1)
coroutine.yield(cor)
print("coroutine yielded")

he used to? what matters to others is if this is real in the scripting worlds (this is scripting not programming because we're using an engine)

This works in RBX.lua

I use them whenever I want a script that does a lot at once without all the lag.
