[JASS] silly noob question

[bloodybrains]

How do you write multiple if conditions in JASS?
EX: if (thisIsTrue and thisIsTrue2) then
call DoSomething
endif

 

[Silvenon]

function Conditions takes nothing returns boolean
    local unit u = GetTriggerUnit()
    if (IsUnitType(u, UNIT_TYPE_HERO) and IsUnitEnemy(u, Player(0)) and IsUnitAlly(u, Player(1)).......) then
        call DoSomething
    endif
    set u = null
endfunction

?


I don't understand, what's wrong with your method? What is it that you don't understand? Just connect booleans with and or or.

I am using JassCraft and when I typed 'and' it didn't color the text. So I thought there was a unique JASS method for it. But I soon realized (using JassCraft anyway) that 'And' was the correct syntax and it is a function (And(boolexp,boolexp)) that returns a boolexp.
Thanks for your reply.

 

[Silvenon]

Avoid using And() and Or(), because those functions generate a boolexpr that leaks. The reasong JassCraft didn't highlight it is because it just doesn't have that in it's highlight list (whatever it's called). Better use and and or, it's much simpler to use anyways.

and/or/not = boolean operators. Compare/change booleans, producing new ones.

And()/Or()/Not() = boolexpr functions. Compare/change boolexprs, producing new ones.

Since you should be working with booleans as much as possible, use and/or/not.

NOTE: They're not functions, they're just... erm, keywords? They're kind've in the same category as 'if' and such. (they're not functions, not variables, parsed by the language, etc, etc)

I think they are called "statements", I think I read it somewhere at wc3c.

 

[PurplePoot]

I know there are if-statements, loops (which are statements), and such, but I don't think and/or/not are statements.

I may very well be wrong, though.

 

[HappyTauren]

well, all jass scripting programs highlight them same way as if,loop,function,struct etc.

Not every jass scripting program highlights them like that, or at all.

Of course and/or/not are not functions, I think everyone who isn't a complete jass noob knows that.

 

[PurplePoot]

Well, he was confusing them with And()/Or()/Not() >_>

Anyways, I don't think the default JassCraft template highlights them at all.

Also, just because they're highlighted the same way doesn't mean they're the same. I mean, programs like JassCraft highlight natives and custom functions the same way

 

[Silvenon]

Yeah, I think JassCraft doesn't know them at all, he's mixing them with And()/Or()/Not() too

 

[HappyTauren]

And Or and Not are operators -.- How could I bee so dumb...

 

[PurplePoot]

No, and/or/not are operators. And/Or/Not are natives...

native And              takes boolexpr operandA, boolexpr operandB returns boolexpr
native Or               takes boolexpr operandA, boolexpr operandB returns boolexpr
native Not              takes boolexpr operand returns boolexpr

 

[HappyTauren]

oh f**k I never use those that start with uppercase (functions) wth did I type it XP

 

[Silvenon]

Omg HappyTauren....
