[General] 2 units share 1 life

[AtivEnergy]

Greetings!
In my problem I have 2 units (buildings) one in top of another preplaced in the map and I wish to make an optimized trigger that can manages to make the life of one unit dependent on the life of the other unit.

Example:
Unit 1 = 1000 hp
Unit 2 = 1000 hp

Unit 1 is attacked by a random unit and now has 900 hp -> Unit 2 must have also 900 hp
Unit 2 is attacked by a random unit and now has 800 hp -> Unit 1 must have also 800 hp

I've made this trigger and works well, but I think is not optimized.

• Events
  • Unit - A unit Takes damage
• Conditions
  • (Damage Target) Equal to Unit 1
• Actions
  • Wait 0.01 seconds
  • Unit - Set life of Unit 2 <gen> to (Life of (Damage Target))

• Events
  • Unit - A unit Takes damage
• Conditions
  • (Damage Target) Equal to Unit 2 <gen>
• Actions
  • Wait 0.01 seconds
  • Unit - Set life of Unit 1 <gen> to (Life of (Damage Target))

If someone know a better solution, the help will be appreciated!

Hello Ativ! How you doing? I made another solution that deals damage instead of setting life.

• Untitled Trigger 001
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Set VariableSet Unit[1] = Farm 0000 <gen>
    • Unit - Add Animate Dead to Unit[1]
    • Unit - Set level of Animate Dead for Unit[1] to 2
    • Set VariableSet Unit[2] = Farm 0001 <gen>
    • Unit - Add Animate Dead to Unit[2]

• Untitled Trigger 002
  • Events
    • Unit - A unit Takes damage
  • Conditions
    • (Level of Animate Dead for (Damage Target)) Greater than 0
  • Actions
    • Trigger - Turn off (This trigger)
    • Unit - Cause (Damage source) to damage Unit[(Level of Animate Dead for (Damage Target))], dealing (Damage taken) damage of attack type Chaos and damage type Universal
    • Trigger - Turn on (This trigger)

-A unique ability is used for the triggers condition and its level is used as an index to deal damage to the other one
-Trigger is turned off/on to prevent an infinite loop while dealing more damage
-Chaos usually deals 100% to all types while Universal ignores armor damage reduction



The reason you need a small wait in your solution is because the damage is applied a small instant after the damage event. An instant can be achieved by starting a timer at 0.00 seconds and doing actions when the timer expires. Your solution is probably a bit safer than to deal damage because of altercations that can occur with the damage amount, so heres how you can do that.

• Untitled Trigger 002
  • Events
    • Unit - A unit Takes damage
  • Conditions
    • (Level of Animate Dead for (Damage Target)) Greater than 0
  • Actions
    • Unit Group - Add (Damage Target) to Group
    • Countdown Timer - Start Timer as a One-shot timer that will expire in 0.00 seconds

• Untitled Trigger 003
  • Events
    • Time - Timer expires
  • Conditions
  • Actions
    • Unit Group - Pick every unit in Group and do (Actions)
      • Loop - Actions
        • Unit - Set life of Unit[(Level of Animate Dead for (Picked unit))] to (Life of (Picked unit))
        • Unit Group - Remove (Picked unit) from Group.

EDIT: I ran some damage tests and it appears that the instant part causes issues with a lot of damage events. So dealing damage does seem better unless theres another solution. On dealing damage I dealt 10k damage to two 10k units whilst with the set life I dealt 12k damage to two 10k units.

Hello Duck! I am doing fine, working on a new map! I hope you're doing great as well!
Thank you for your help, but I think there was a misunderstand because of my bad english.
I tried your suggestion, but work with only 1 building.. I want to work even in reverse. Right now works only if I attack farm 2.
In my example I've made 2 triggers for unit 1 and for unit 2, but i don't know how to adapt your trigger in order to work for both units.
Also, why you use this "Unit - Set level of Animate Dead for Unit[1] to 2" just for unit 1?

This condition, (Level of Animate Dead for (Damage Target)) Greater than 0, checks if the (Damage Target) has the ability Animate Dead. A level of 0 means that the unit doesnt have the ability and a level greater than 0 means that the unit has the ability. Unit[1] has the ability at level 2 and Unit[2] has the ability at level 1. We can therefore also use the Level of Animate Dead for (Damage Target) to reference the other unit. See the example below.

Unit[(Level of Animate Dead for (Unit[1]))] = Unit[2]
Unit[(Level of Animate Dead for (Unit[2]))] = Unit[1]

• Unit - Cause (Damage source) to damage Unit[(Level of Animate Dead for (Damage Target))], dealing (Damage taken) damage of attack type Chaos and damage type Universal

The problem that happened for you is probably because the example ability Animate Dead that i chose usually only has 1 level so it cant be set to level 2. I would create a custom version of Item Armor Bonus (+1), set the Defense Bonus to 0 and set Levels to 2 and use that ability instead. The reason I would use that ability is because its not active and it doesnt show an interface icon when added to the units.

 

[AtivEnergy]

You were right. The problem disappears if I set the "animate dead" spell in the ability editor to level 3 for example.
Thank you!

Edit: Now I understand.. Unit[(Level of Animate Dead for (Damage Target))] is actually an integer Unit[1 or 2].

Be aware that this will mean the buildings take double damage from anything that damages buildings in an AoE. Earthquake, Cyclone, Blizzard with targets allowed including buildings, ‘pick every unit in range’ looking for buildings, etc..

Thank you for the advice! Fortunately, both buildings are immune to spells on my map.
