Globals

[Charapanga]

Hi, another problem i have encountered with...Globals as in the function...globals where you set variables Example:

globals
   unit u
   integer i
   real r
endglobals

Do you need to preset them like UDG? or are they created like the example above?

 

[Larcenist]

Like what you write inside the global blocks. The only globals that require the udg_ prefix is the ones created in the variable editor.

you shouldnt use short names for globals, better are descriptive and non repetive names. But it should work like this, yoou dont need a prefix

Ok, thanx

I use short names for public and private globals.
Its no problem if you use scopes&libraries:

scope A

globals
    public group G  = CreateGroup()
    private timer T = CreateTimer()
    private constant integer BUFF_ID = 'B000'
endglobals

endscope

scope B

globals
    public group G = CreateGroup()
    private group G2 = CreateGroup()
    private timer T = CreateTimer()
    private constant integer BUFF_ID = 'B001'
endglobals

endscope

I got another question about Private globals... Does using them make a spell MUI or make it un-MUI?

 

[Flare]

No and no - private doesn't affect how the actual code runs, it's just to avoid naming conflicts. If something is MUI with a normal global, it'll be MUI with a private global. Same applies to non-MUI

 

[Charapanga]

so, if i make a spell with only privates, it will be MUI? It includes timers so it's not just like an instant spell...Beacuse first i made it with Locals, but it had to include waits since callbacks can't take arguments and it was MUI but it wasn't really what i was hoping for

And since it's a blink-strike kinnda spell i can't test it with beacuse i'm not that fast...

 

[Larcenist]

What Flare said is that private variable does NOT make them MUI automatically. All it does is name the variable so that it's named as the struct/library in which it is declared. It's still like any other global variable.

(From JASSHelper manual)

Notice how both libraries have private globals and functions with the same names, this wouldn't cause any syntax errors since the private preprocessor will make sure that private members are only available for that scope and don't conflict with things named the same present in other scopes. In this case private members are only to be used by the libraries in which they are declared.

scope Test
globals
  private integer PrivateInteger
endglobals
endscope

would end up being something like

globals
  integer Test_RandomPrefix_PrivateInteger
//From what I recall, the RandomPrefix is a random 5 (or 6) digit number, according to the Grimoire error messages
endglobals

after the map script is compiled

So, it's doing nothing other than giving it a modified name so that it's inaccessible outside of this scope, and the name of a variable doesn't have any impact on the MUI capability of a spell/system that uses private functions or globals. A global will act as a global, regardless of public/private status, so a private global will face the same MUI issues that any other global would face
