Perfect IsUnitAlive

[GoGo-Boy]

So do you think it is speed-wise better to use UnitAlive() instead of GetWidgetLife()>=4.05?

 

[Komaqtion]

I just did some minor testing on this, and it doesn't seem to work

This actually fatals, but I've discovered that it's the "out-commented" lines which causes it:

library TestNatives initializer Init

    private function Actions takes nothing returns boolean
        call DisplayText( 0, "Hellu !" )
        
        if UnitAlive( gg_unit_Hpal_0003 ) then
            call DisplayText( 0, "He's breathing !" )
        endif
        
        /*if UnitInvis( gg_unit_Hpal_0003 ) != true then
            call DisplayText( 0, "I can see him !" )
        endif*/
        
        call DisplayText( 0, I2S( GetHeroId() ) )
        
        call DisplayTextI( 0, "Huh !", 123 )
        
        return false
    endfunction
        

    private function Init takes nothing returns nothing
        local trigger t = CreateTrigger()
        
        call TriggerRegisterTimerEvent( t, 0.00, false )
        
        call TriggerAddCondition( t, Condition( function Actions ) )
        
    endfunction
    
endlibrary

But as I said, this doesn't display anything, or isn't that what "DisplayText" is supposed to do ? :S

(I'll now try it with "DisplayTextToPlayer" instead )

UnitInvis crashes and burns. For some reason. The DisplayText things don't work at all. Like I said, only a handful work.

>So do you think it is speed-wise better to use UnitAlive() instead of GetWidgetLife()>=4.05?

Possibly. I think that it draws upon some internal boolean that Warcraft 3 itself uses to know that units are dead. That would make it faster.

 

[Komaqtion]

I've also discovered that this crashes:

call CreateCaptains()

And:

call DisplayTextToPlayer( Player( 0 ), 0.0, 0.0, I2S( GetUnitCount( 'hpea' ) ) )

And also, and this is quite useful I'd believe, this will give you the last built structure of a player (Though, don't know if it'll desync :S But wouldn't think so ):

    private function GetLastStructure takes player p returns unit
        local unit u
    
        if GetLocalPlayer() == p then
            set u = GetBuilding( p )
        endif
        
        return u
    endfunction

Try it out !

 

[Azlier]

Are you sure that that won't desync if used online in combination with something else?

That also leaks a unit handle id.

GetPlayerUnitCountOfTypeOrWhatever works fine, and I found a perfect use for it, since it doesn't count dead units.

 

[Komaqtion]

Nah, but why would it ? :S
It's not like it'll change anything right ? :S

But please, if someone wants to test it then tell me

That also leaks a unit handle id. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" />

Yeah yeah... XD
Can't be helped (Right ? :S)

Yeah, I meant GetUnitType will crash, not GetPlayeRUnitTypeCount (As it's called )

If u is null for everyone but one player, then you kill u, what do you think will happen
Desync... I guess you could use it with select unit or something.

Also, GetUnitXCost crash when you use them on heroes, I found that out when I wrote my CWAL thingy.

 

[Azlier]

>Also, GetUnitXCost crash when you use them on heroes

Yes, I know. Forgot to mention that.

Probably has to do with how heroes cost more the higher the tier you get them in.

Well, might there be a way to prevent it ? :S

Go common.ai natives?

Komaqtion, 100% chance that will desynch (on the condition it works at all).
You are returning a different value to each player.

 

[Komaqtion]

Yet again:

[Azlier]

Yeah. Don't use that native. There's a better way by using the events Blizzard gave us in common.j.

 

[kingkingyyk3]

lol, where did you find it?!

 

[Azlier]

Common.ai

 

[kingkingyyk3]

Woha!

 

[LearningCode]

Is this a momentous event for JASS coding? xD

"The discovery of new natives found in the ancient, forgotten civilisation that is the Common.ai"

Well, Azlier and the crazies like Nestharus and I have known about Common.ai natives for some time, but this is like... really useful. Simply because we had a discussion about how nothing works.
PS. Does this detect a unit with 5 health and no dead status as dead, if it is?

 

[Azlier]

In the first post, I already stated that this detects dead units with increased health (AKA, above 1) health as dead.

 

[Jesus4Lyf]

PS. Does this detect a unit with 5 health and no dead status as dead, if it is?

That's why I had to ask.

function SchrodingersCat takes nothing returns unit
    local unit u=CreateUnit(Player(15),'hfoo',0,0,0)
    call SetWidgetLife(u,0)
    call SetWidgetLife(u,9001)
    call UnitRemoveType(u,UNIT_TYPE_DEAD)
    return u
endfunction
function Test takes nothing returns nothing
    if UnitAlive(SchrodingersCat()) then
        call BJDebugMsg("Alive")
    else
        call BJDebugMsg("Dead")
    endif
endfunction

What's it return?
Edit:
And what's this return?

function HiddenDragon takes nothing returns unit
    local unit u=CreateUnit(Player(15),'hpea',0,0,0)
    call ShowUnit(u,false)
    return u
endfunction
function Test takes nothing returns nothing
    if UnitAlive(HiddenDragon()) then
        call BJDebugMsg("Alive")
    else
        call BJDebugMsg("Dead")
    endif
endfunction
