2 JASS and 2 vJASS questions

2 JASS, 1 Zinc and 2 vJASS questions

These questions might sound noobish but I'm stuck on them.

JASS Questions:

1. 
   What are widgets? [Got it]
2. What are boolexprs?

vJASS Questions:

1. 
   Can textmacros be dynamic? Like:
   

   //! textmacro TM takes STR
   call BJDebugMsg("$STR$")
   //! endtextmacro
   
   function test takes string s returns nothing
   //! runtextmacro TM(s)
   endfunction

2. I don't get it... What is extending structs?
   

   struct ExtendingStruct // I get this one
   endstruct
   
   struct x extends ExtendingStruct // I get it too
   endstruct
   
   struct y extends array // I don't get this one
   endstruct

Zinc Question:

I've tried to learn 2D arrays when I wanted to learn Java/C#, but I failed.

Can someone tutor me multidimensional/2D arrays?

JASS:
1) From what I've heard - widgets are "objects" - destrucatbles, units, items, etc... It just covers a bigger part of the family.
2) I'm not sure......

vJASS:
1) You can, but it'd look like //! runtextmacro TM("s")
2) I may lie to you about this one, but I think it works like this:
Struct A
real x
endstruct

struct B extends A
real y
endstruct

struct C extends B
real z
endstruct

now A has only .x
B has .x, and .y
C has .x, .y and .z

Thanks, I got widgets and struct extending struct, but what about struct extending array?

About the textmacro, I think my example was misleading. Check this one:

function FuncSimple takes nothing returns nothing
    //things
endfunction

function FuncSimpler takes nothing returns nothing
    //things
endfunction

function FuncMoustache takes nothing returns nothing
    //things
endfunction

//! textmacro meh takes str
call Func$str$
//! endtextmacro

function CallFunc takes string s returns nothing
//! runtextmacro meh(s)
endfunction


//Somewhere in the middle of some script
call CallFunc("Simple")
call CallFunc("Simpler")
call CallFunc("Moustache")

BPower wrote a nice tutorial about struct extending struct : [vJass] Meet vJass - Extending structs

For struct extends array, it just removes all the struct functions like allocate() and deallocate() from it. So you will need to code all things yourself.

Textmacro wouldn't works in that way. It get ran when pjass compiling the code. Not in game.

About boolexpr :

function test takes nothing returns boolean
	return GetEnumUnit() == Player(0)
endfunction

function init takes nothing returns nothing
	local boolexpr b = Condition(function test)
	local boolexpr b2 = Filter(function test)
	local group g = CreateGroup()
	
	call GroupEnumUnitsInRange(g, 0, 0, 0, b)
	call GroupEnumUnitsInRange(g, 0, 0, 0, b2) //works as well
endfunction

Mostly, people don't use boolexpr as can hardly find a use for it.

Oh, now I understood the structs extending arrays. Thanks for that link!

So boolexprs are some sort of booleans that are dynamic...?

Well, I'm not sure about what you meant by "dynamic boolean", it can be used when the input argument requires filterfunc, conditionfunc because both of them extend boolexpr

 

[Arad MNK]

Dynamic boolean, like some code that is ran to return a boolean and according to it's calls returns it becomes dynamic.

Anyway I think I got that too.

AAAAND I managed to find the 2D Array thing as well.

Thread had served it's purpose. Thanks. +REP
