No pointers?

12-23-2002, 07:36 PM

Does JASS uses pointers or not? Let me explain. I have a function that modifies a string.

Can I do something like (in WorldEdit)

Code:

call MyFunction( "Some String", udg_STRING_SomeWEVariable)

And have MyFunction do something like

Code:

function MyFunction takes string str1, string str2 returns nothing
    str2 = (str2 + ( ";" + str1 ) )
endfunction

MyFunction would be in Blizzard.j or something.

If that is not possible, anyone has a suggestion to go around that limitation?

Thanks.

Guest	I don't think your function would work, because I don't believe parameters are passed by reference in JASS. I could be wrong on this, but that's how I understand it. If, on the other hand, you did this: Code: function MyFunction takes string str1, string str2 returns string local string finalstr finalstr = (str2 + ( ";" + str1 ) ) return finalstr endfunction That SHOULD work.

BahamutZERO	Yeah but then that becaomes ugly to use in World Edit. Thanks though. And yeah, they are probably passe by value. Shame. Maybe there is a secret syntax for passing by ref. We'd have to explore that possibility.

DKSlayer	I believe that there is some stuff, we don't know about yet. Maybe not tons of stuff, but some things that JASS does that isn't documented/used. I think when I get a chance one of these times I will sit down and work on some features that most other languages have yet this one doesn't seem to have. I'll post my findings when I get a chance.
