Help with a spell

[VergilSSS]

Hey guys.

I have been trying to make a spell that, when casted will deal eg:100 pure damage + your attack damage and heal caster equaly to total damage dealt, but i am failing for quite some time, since i do not know how to do triggers that will heal up caster for his attack damage...

Could you post trigger about how to do this spell, or simply teach me how to do it?

Thanks in advance.

Probably the easiest way to do it would be to manually calculate a random number to use as the damage and apply it that way. However, this will probably not be truly accurate since you have to take into account the number of dice and the number of sides, and so on.

The best way to get the damage that a unit deals in-game is the Unit Takes Damage event, since it has a function to grab how much damage was dealt, however, this requires that an attack has actually been made....

 

[VergilSSS]

Yes, that is what i tried to do, but i could not do it...

 

[darkreapers]

i dont think its possible to do your attack damage, however you could try doing your agility/intel/strength including or excluding bonuses as damage?

 

[VergilSSS]

perfect idea darkreapers, its easy to make and almost same effect...thanks

My way would be much more complicated but maybe work better, maybe not. the checking str/agi/int way wouldn't take into account any +damage items, abilities, or buffs. My way would but it might possibly malfunction in other ways depending on the units attack speed and the spells cooldown.

I would make the spell based on Black Arrow with 100 bonus damage and i would use 2 triggers. 1 trigger for "starts the effect of an ability"/"Ability being cast equal to Black Arrow" and that trigger would create a local trigger for when the target of the spell being cast takes damage (because that event requires a specific unit) and then in the local trigger's actions you could use damage taken (it would be the caster's attack damage + 100 minus any resistences or armor) and heal the damage source (the caster) for that much damage and have the local trigger self destruct (destroy it self!)

Now, I say it might malfunction depending on attack speed and spell cooldown because it might be possible for it to be cast twice before the 1st projectile hits and in that case the 1st hit would heal double. one way around that would be to keep a global unit group that has all the targets added to it and only create the local trigger if the target is not already in the group then add a condition to the local trigger to check for the Black Arrow buff to make sure the trigger doesn't go off from other damage sources.

Err... could you explained it in a GUI form?

 

[Grundy]

nope. i don't use gui. you should learn jass.

Sure.

This will take a few triggers.

The main trigger will have no event to start, and will have a damage event added to it with another trigger. You have to do it this way because there is no general Unit Takes Damage event; only for specific units Conditions will be that Triggering Unit has specific buff (whatever buff you choose to use for the spell) and Level of (the Ability for the spell) for the Damage Source is greater than 0. Actions will be to remove that buff, and set the Damage Source's life to its Current Life + Damage Taken.

The next trigger will have event Unit starts the effect of an Ability, conditions Ability Being Cast equal to Your Ability (base it off of, say, frost arrows). Actions will be to check if the unit is in a unit group variable (name it whatever you want), and if it is not in the unit group, add it to the unit group and add to the first trigger the event Target Unit Of Ability Being Cast takes damage. The unit group check is to make sure you don't add the damage event more than once per unit or the trigger will start running multiple times.

Pretty short triggers. This won't work if the ability is set to autocast, though - only if you manually target it. It'll work for autocast if the event of the second trigger is A Unit Is Attacked, and you change Target Unit of Ability Being Cast to Triggering Unit and change the conditions to check whether Attacking Unit has a level of the spell ability greater than 0.

In 2nd trigger, change the unit group to loop and give some custom scripts (I think thats for to remove the leaks)

Instead of making it check a group like this, why not do it this way.

    • Unit - Remove Healing Arrows buff from (Triggering unit)
    • Set RealDamage = ((Damage taken) + YOURDAMAGE)
    • Unit - Cause (Damage source) to damage (Triggering unit), dealing (YOUR DAMAGE) damage of attack type Chaos and damage type Universal
    • Unit - Set life of (Damage source) to ((Life of (Damage source)) + (RealDamage))

That would also work, though you might need a third trigger that runs on map initialization to add the damage detection for pre-placed units. Using the triggers I posted would only add events for targets of the spell; adding damage detection for every unit on the map would make the main spell trigger run and have to check its conditions every time any unit takes damage. :nuts: That might not be a big deal, but it's still less efficient.
