[Orb] Percentage Armor Reduce

[KPC]

An orb that reduces armor by 25%. Similar to orb of corruption.

I'm trying to make it using damage engine.

Damage Engine 5.7.1.1

Event is when unit loses hp
Condition Hero manipulating Item - Orb

I'm using Item armor bonus with multiple levels and negative values:
Lvl 1: 0
Lvl 2: - 1
Lvl 3: - 2
etc.

So unit gets armor reduction instantly by having this ability.

Changing its levels changes the value of reduced armor.

I also use Armor Detection System, that makes it possible to get units armor value.

I made this so far. But I don't know how to remove effect or keep it properly. I just turn it off after 5 seconds but it also happens when unit is still attacking and still have the effect. It causes it loses effect for a moment with no reason.

You can't use Waits like that.

DamageEventTarget is a global variable, which means that it can only be set to a single value at a time.

And whenever a unit takes damage, the Damage Engine sets DamageEventTarget to be equal to that damaged unit.

So when you do "Wait 5.00 seconds" and then try to reference DamageEventTarget there's a very high chance that the variable has been set to an entirely different Unit by that time.

Also, the way you're removing the ability is incorrect. You're creating many Waits that will stack up, each Wait removing the ability once finished.

You attack once -> A 5.00 second Wait starts
You attack 1 second later -> Another 5.00 second Wait starts but keep in mind your previous Wait is still running and is now down to 4.00 seconds
You attack 3 seconds later -> Another 5.00 second Wait starts, and now your 1st Wait is down to 1.00 second and your second Wait is down to 2.00 seconds
Etc...

Each time one of these Waits finishes you're going to remove the ability. See the problem?

So how exactly do you want the ability to work?

Do you want it to "refresh" or reset the Wait so that it goes back to 5.00 seconds after every attack. Or do you want each instance of Armor Reduction to wear off after 5.00 seconds (so like after 5.00 seconds the enemy gains 1 Armor back).

1. I'm not suere but creating local unit might help with damage event overwrites.

2. I wanted it to least 5 secinds from last attack. Idea with gaining 1 armor back per second is very interesting. Seems like the best of those. Just imagine: Orb of Pain reduces the armor by 25% but unit will recover its armor poins coz effect of pain is stopping.

This uses a Unit Indexer, Devotion Aura with -25% Armor, and a local variable (like you mentioned). If you already have a Unit Indexer in your map then make sure not to add another.

          • Else - Actions
      • Else - Actions
        • Set VariableSet AR_Counter[CV] = 0
    • Custom script: set u = null

It's a fairly simple concept. We keep track of a Counter on our damaged unit, each attack increases the Counter by 1, and 5.00 seconds after that attack the Counter is reduced by 1. If the Counter reaches 0 then we know that the unit hasn't been attacked in the last 5.00 seconds and we can safely remove the Armor Reduction ability from it.

Edit: I forgot to null my local variable. I also forgot to remove the Armor buff. It's fixed now.

Greetings friend.

 

[KPC]

Do You have idea how can I also slow movement speed of attacked unit?

 

[Uncle]

Do You have idea how can I also slow movement speed of attacked unit?

You can order a Dummy unit to cast Slow on the target or Add a negative Slow aura to it like a modified Endurance Aura.

 

[KPC]

I did it by trigger. I've also tried with Item Move Speed Bonus with negative value. Imagine that it worked only with positive value. Don't know why. Thanks for help.

 

[KPC]

Do you know how can I make this orb effect unique? I mean when u have 2 orbs only 1 works but with this one both works.

Please refrain from double post
Follow Grog'nar and use the "Edat Bootan"

In the conditions you can check if the DamageEventSource has any other orb effects.

DamageEventSource has Orb of Lightning equal to False
DamageEventSource has Orb of Frost equal to False
etc...

Let me ask you about this:

If - Conditions

• 
  
  
  
  
  (AR_Unit is alive) Equal to True

You know, when I test map this causes not removing effect from here when he dies and you revive him.

 

[Uncle]

As long as the revive delay is longer than 5.00 seconds (the duration of the Wait) it should be fine.
