[JASS] Local Vars. and MUI

[Undifty]

I've been trying to learn Jass and it goes pretty nice this far, though there's one thing I'm slightly confused about..

I recall reading on one of the tutorials that local variables only exist in the function they were created/declared in.

So

If I have to use global variables in spells that has more than one function, how can I possibly make it MUI? (In GUI I used arrays but I wonder if it's just me being confused or if there's any easier way)

Cheers.

Yes, local variables are only accesible in the function they were declared in.
For MUI making, use Local handle vars. They allow you to store anything onto a handle.

You can also pass local varables from function to function, but the only way to pass them to something that uses events of timers is like diablo said, HandleVars or other such systems.

Aye thanks, I found some info about handlers so gonna give it a try now

Well, since you are learning, I guess it is ok to go into handle vars and less in depth, but you should know they are rusty. Handle vars are lessed used now because they have been proven to be, well, erm, "rusty" as I said. Captain Griffen told me that a while ago and said to ask PipeDream or Vexorian to give ya a clear reason. So, if ya need info about it, just ask.

Anyways, the alternative option is to use either CS_Cache's tables or even better yet, use vJASS's structs/globals.
