Mana drain on attack? :)

[Da InF]

Hey, i tried making this myself, and i just dont see why it dosen't work, to me it seems kinda simple.. yet.. dosen't work .. well, i wan't an abillity that gives the hero 2%,4%,6%,8% and10% of it's damage it deals to enemies to its own mana, so that if it deals 100 damage, it will at level 5 give the hero 10 mana, now.. here is what i did

Event:
Any unit is attacked



Conditions:
Level of (mana burn spell dummy) is greater or equal to 1

Type of attacking unit Equal to (Hero type)



Actions:
Set Variable (lifeoftarget) to life of attaced unit

wait 0.5 seconds
set attacking units mana to (lifeoftarget) - (life of attacked unit*(level of (spell dummy for (hero))*0.02)


Set Variable (lifeoftarget) to life of attaced unit

wait is a bat decision. Many ingame defined variables such as attacking unit witch you used here are deleted in a very short period of time.

 

[Da InF]

Perhaps, but as the trigger is triggred by "attacked" it is therefore the order of attack that triggers the trigger and again therefore will the trigger then execute before the target has lost hp and again then not work, see? :/-.- any other way to do this you think ?

 

[Volvox]

1. you didn't get me
2. try assembling a bit less complex sentences cuz the one above makes almost no sense
3. what you say is not true, just set the attacking unit in a variable and then refer to it after the wait

• ManaDrainOnAttack
  • Events:
    • Unit - A unit deals damage
  • Conditions:
    • (Level of (ManaDrainAbility) for (Triggering unit) Greater than or equal to 1)
  • Actions:
    • Unit - Add ((Damage dealt) x ((Level of (ManaDrainAbility) for (Triggering unit)) x 0.02 ))) to (Triggering unit)'s mana

ManaDrainAbility should be a passive dummy ability that does really nothing (can be a 0% chance critical strike)
Watch for brackets in the multiplying, the order they're placed is important.

 

[Volvox]

That's definitely a more efficient way.

 

[PurplePoot]

Except for the fact that you have to custom make that event, and doing it properly isn't trivial (in GUI anyways)

But yeah, A Unit Is Attacked does suck more than making that event.

 

[raft_pl]

Poot, you mean that there is no such event as "a unit takes damage"? Goddamn...

 

[PurplePoot]

There is one, but only for specific units.

An example of global implementation: http://www.wc3jass.com/viewtopic.php?t=2608

I suck at JASS, few times i tried to learn it, but i've never understanded it Anyway, i'm sure there is a way to overcome this in GUI, but it's a long one, though...

 

[Da InF]

...

Firstly, never seen "unit deals damage" event and i doubt it exists.
And, yes i realize this is a very dodgy way to achieve what i want, but i don't see any other way, oh and the fact that my earlier post didn't make much sense is prolly because i was very tired, sorry about that.

Now if anyone have an answer/solution, i'll still love to hear it, since the Hero using this is somewhat depending on this spell

 

[raft_pl]

I dont have w3 right now on my computer, and i dont remember all the events Blizzard made in WE =/

Anyway, i'd love to help you, but you've read what Poot wrote - it can be easly made, but in JASS, at which i'm lame... Try waiting for somebody who knows it or post at JASS section

 

[Da InF]

Heh, i have no idea how to use JASS eiher im afraid so :/

Instead of A unit takes damage, use A unit is attacked.

• Untitled Trigger 001
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Level of Drainperattack for (Attacking unit)) Greater than 0
  • Actions
    • Unit - Create 1 Dummy for (Owner of (Attacking unit)) at (Position of (Attacking unit)) facing Default building facing degrees
    • Unit - Set level of Feedback for (Last created unit) to (Level of Drainperattack for (Attacking unit))
    • Unit - Add a 2.00 second Generic expiration timer to (Last created unit)
    • Unit - Order (Last created unit) to Attack (Last created unit)

The dummy should have a 1 damage attack enabled, with an attack cooldown of at most 10 seconds, at least 5 seconds, to ensure it doesn't attack twice. (overkill, I know...) it should have the feedback ability.

Or why bother triggering, if you could just add the feedback ability to the main attacking unit?

BTW... I know, A unit is attacked isn't so efficient, since it triggers before the damage is dealt, but what the heck. Unless you do it in JASS, then you're forced to use it.

 

[raft_pl]

Feedback drains a preset number of mana, not percentage of damage dealt, tought... I dont remember...

 

[Altazen]

Okay, I'll try to modify the trig...

 

[Alkonis]

What I would to is have a trigger which fired whenever that unit attacks, then create a local trigger or add an event to a GUI trigger that already has conditions/actions saying that the attacked unit takes damage. Then, get the damage dealt and multiply it by .10 or whatever and add it to the unit's mana. I'd post the JASS for it, but I'm not sure if it'd help any.
