I dont know how to indicate simple (I think) condition

[leopold39]

I have a little question. I created something like this:

Event:
Unit X - dies
Action:
Unit Y changes ownership to Neutral Hostile
Unit Y replaces with Unit Z using Maximum HP and Mana


I want to make condition that Unit Y must be alive, but I don't know how. Could you help?

Use "Unit Y is Alive equal to True" (under boolean comparison) in the conditions area.

This isn't 100% accurate so if you want to be super duper sure it's alive, check if it's health is > 0.5 too.

Care to elaborate Kaijyuu?
Always worked as described on my end.

Honestly I'm just repeating what I've heard from other people and have never experienced any bugs myself. The "unit is alive" GUI condition apparently isn't always accurate and it's usually better to check HP. Dead units also have a "UNIT_TYPE_DEAD" unit type which I check as well, though you have to do that in a custom script since there's no GUI option for it.

The GUI conditions check whether hp <= 0:

function IsUnitDeadBJ takes unit whichUnit returns boolean
    return GetUnitState(whichUnit, UNIT_STATE_LIFE) <= 0
endfunction

A unit is considered dead, if hp <= 0.405.

• Untitled Trigger 001
  • Events
    • Player - Player 1 (Red) skips a cinematic sequence
  • Conditions
  • Actions
    • Custom script: local unit u
    • Unit - Set life of Rifleman 0000 <gen> to 0.40
    • Unit - Set life of Rifleman 0000 <gen> to 8.00
    • Game - Display to (All players) the text: (String((Life of Rifleman 0000 <gen>)))
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Rifleman 0000 <gen> is alive) Equal to True
      • Then - Actions
        • Game - Display to (All players) the text: alive
      • Else - Actions
        • Game - Display to (All players) the text: dead
    • Custom script: set u = gg_unit_hrif_0000
    • Custom script: if( IsUnitType(u, UNIT_TYPE_DEAD) or GetUnitTypeId(u) == 0) then
    • Game - Display to (All players) the text: really dead
    • Custom script: else
    • Game - Display to (All players) the text: really alive
    • Custom script: endif

Rifleman will die because hp<=0.405, but after that you set his hp to 8 and the text message will print 8. Also conditions to check whether the unit is alive/dead will be wrong afterwards. It's very rare though to set hp of a dead unit.

I found a method here [code=jass] Checking if a unit is dead - Wc3C.net to check if the unit is really dead. It uses UNIT_TYPE_DEAD like Kaiyuu said.

I would guess it also causes problems with reincarnation. You can argue whether a reincarnating unit is dead.

IIRC Tranquility increases the hp of dead units which can trip up triggers.

Thanks for help Kaijyuu.
