[Trigger] Making an absorb system

[Sunchips]

I need help making an absorb system and Im not familliar at all with jass

I want to make a spell that blocks up to a certain amount of damage from the next damage source

I use the Gdd gui friendly damage detection system (think thats the name) and I belive its possible to use this for the system I want.

Any help is appreciated and reputation shall be given!

A damage detection system (like most events) actually fires before the damage occurs, so you just want to increase the unit's max HP by how much damage they will take, heal them that much, wait until the damage actually happens (a 0 second timer does this best), then reduce their max HP.

That's not true, actually an attack event fires before damage occurs, but DD on the other hand fires 'when' damage occurs...

The problem with DD systems is that it will damage you first before the event takes place, say if you have 10HP left, and
you already have a damage blockade, then your unit will die in that manner...

Imo, it's better to blockade the damage dealt with a timer (set your life at constant) or on every attack (although it's abusable in many cases)...

I'm not sure how to say this nicely, but: this is wrong, and please don't contradict people with much more experience than you modding wc3 without at least testing your claims first.

Here is a map which disproves your claim:

 

[mckill2009]

try to reduce the HP of your footman to less than the damage dealt, it will fire before the Laster code...

That's the point. Last (the action for the on-damaged event) fires before damage is dealt, but Laster (a 0-second timer later) fires after it's dealt, so you would add HP+maxHP in Last and remove it in Laster, an instantaneous amount of time in the eyes of the player but long enough to capture otherwise lethal damage.

Im getting most of your drift but... Hum laster code?

 

[Adiktuz]

yes, the fact is that the event Unit Takes Damage is actually fired before the damage is actually dealt that is why creation of "anti-death" things is possible...

@OP: you better shift to Bribe's GUI Damage Engine, its better...

Referring to the code in the test map I posted.

 

[mckill2009]

So you mean to say that all DD systems there such as GDD is not accurate coz there's no 0 sec interval?, it doesnt land properly?...

 

[Adiktuz]

Nope... That fact is actually the reason why we can make a lot of modifications to damages dealt...

Thx for the replies but I still can't get this together :/

I want to make an ability that gives you a 100 hp shield for the next damage source only and then vanish. I have tried Bribe's Damage engine but I don't really know how to do because the amount isn't accurate and sometimes he even gets healed by the block somehow.

Edit: I remade the trigger and now it seems to work fine but somehow it feels wrong that it was this simple.

Trigger

• Block
  • Events
    • Game - DamageModifierEvent becomes Equal to 1.00
  • Conditions
    • DamageEventTarget Equal to (==) Archmage 0006 <gen>
  • Actions
    • Multiple FunctionsIf (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • DamageEventPrevAmt Less than (<) 100.00
      • Then - Actions
        • Set DamageEventAmount = 0.00
      • Else - Actions
        • Set DamageEventAmount = (DamageEventPrevAmt - 100.00)

Does it look okay? He sucessfully take no dmg if the damage dealt is less than or equal to 100

It really is that simple.

Why not use one of the dozens in the spell section...
I even made one at some stage although that had its share of bugs.

 

[Sunchips]

The reason i dont want any of the ones published in the spell sections dont work as i want and are not made for general use but made specifically made for their own spell with weird effects and i cba going through what do remove from their codes or triggers

 

[PurplePoot]

There are a number of excellent ones, although they do kind of get lost in the deluge of resources. I'm not sure if better systems have since been made, but back in my day Dusk's IDDS was the go-to damage detection system if you didn't want to write your own.
