UnitAlive help

[Ironside]

if I use UnitAlive in triggers, I get error: undeclared function UnitAlive.
Then I tried to put on top of my script:

native UnitAlive takes unit u returns boolean

It still didn't work.
I am using JNGP.

Does anyone know what I can do to get it work?

Perhaps you could use the funtion native GetWidgetLife takes widget whichWidget returns real instead? (I thought TriggerHappy preferred that function, but I'm not really 'into' that stuff xD).
Something like this:

Function

function Alive takes nothing returns boolean
    if GetWidgetLife(GetTriggerUnit()) > 0 then
        return true
    endif
    return false
endfunction

(I tested your function as well and it gave the same error, but I can't find it in the function list, though its color does change, indicating it's a valid function).

By me it doesn't even color itself. And I am using GetWidgetLife, but I'd like to replace with UnitAlive
because I like it more, and it's simply less long...

I'm not sure if changing the argument names the native takes actually works.

Try this?

native UnitAlive takes unit id returns boolean

 

[Ironside]

Still says undeclared function UnitAlive :/

Be sure that you didn't misspell the name. You might've accidentally put like "Unittalive(u)" or something like that. Also be sure that you have the latest JNGP.

Otherwise I don't know why it'd cause syntax errors. As far as I know, the position of it doesn't matter and parameter naming doesn't matter neither. (I've tested it in my haunt spell, it works fine without naming the parameter "id")

 

[Ironside]

Well... I rechecked the name, didn't work, I have jassnewgenpack5d

Well then, the problem beats me. =P I can only think of two other reasons:
- Your common.ai is missing, which I highly doubt unless you messed with your MPQ a lot or something.
- Or the syntax error is referring to some other part of the code. Sometimes it might highlight the wrong line/part. Try posting the code or a segment of the code and show the error.

 

[Ironside]

No I never messed with MPQ files, I don't need them for anything...

EDIT: Ok what the hell... It suddently works now :O

GetUnitState(whichUnit, UNIT_STATE_LIFE) > 0

IsUnitType(whichUnit, UNIT_TYPE_DEAD) == false

?

 

[PurgeandFire]

GetUnitState(whichUnit, UNIT_STATE_LIFE) > 0

IsUnitType(whichUnit, UNIT_TYPE_DEAD) == false

?

I think for the first one, integer comparisons are a bit slower than a direct native and for the second... Well, the second doesn't work in a couple of situations as far as I know. =P

Wait, there is a native for UnitAlive? It's not in the JASS vault on wc3jass.com...

I need to find a better list of natives O_O

Actually UnitAlive comes from the common.ai, which can be used by the AI scripts. It's not normally usable in maps...unless you have Jasshelper where you can declare it and use it normally.

 

[Ironside]

Exactly, I'm sure glad it works now, though it still doesn't color, as if it was not a function at all
