Coroutines and you

Administrator Posts : 878 Join date : 2010-07-30

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.

Well, You can end a loop with the break statement.

I didn't want to put the ends...

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

or print(loadstring("failz scriptz will error in loadstring. xD")())

I wish coroutines were a bit less annoying to use. thats about it.

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")

AHH! Idk. test it?

aaah... I think that would depend on how strong you computer is? your limit is only time, not a specific point.

uh VoidHack? do you even know what your talking about?

Voidhack knows what he is talking about. Or at least, he used to if not anymore.

Guest

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)

he knows what he is talking about. you can't put a wait() in pcall or xpcall but u can in coroutines.

This works in RBX.lua

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

wow! reduces lag?

Got a really good idea? Post it in projects and it might show up here!
