Damage taken trigger

[Emu.Man00]

OK so i want to have a spell that will make you hurt yourself instead of another unit when you attack. I know the basics but i cant make him take the same damage that he would deal.

So my question would be is it possible to make a variable of how much damage a unit would deal?
And if not could you help me figure out another way to do the spell? :S

You'll need to store the damage done.
Two triggers needed, one to catch a unit and add it to your damage taking event.
The other, the damage taking event.

Unit Catch

Unit Catch
    Events
        Unit - A unit enters (Playable map area)
    Conditions
    Actions
        Trigger - Add to Dmg Catch <gen> the event (Unit - (Triggering unit) Takes damage)

Dmg Catch
Globalsys dmg catch
    Events
    Conditions
    Actions
        Set DmgDealt[(Player number of (Owner of (Damage source)))] = (DmgDealt[(Player number of (Owner of (Damage source)))] + (Damage taken))
        Unit - Set life of (Damage source) to ((Life of (Damage source)) - DmgDealt[(Player number of (Owner of (Damage source)))])
        Set DmgDealt[(Player number of (Owner of (Damage source)))] = 0

And you can add a condition to check if the damage taking unit has the ability.

I'm kinda confused about the first line of actions in the second trigger :S

What kind of variables should they be?

 

[DsD)Core(]

Sorry, I forgot to mention. Variables that store damage are always Real. These are Real Arrays, to make them MUI.

What it does is it says if a unit takes damage, it sets the damage done real of the damage source to the damage that was taken by the attacked unit. This variable is then substracted from the attacking unit in form of life, resulting in an exact damage return, and the variable is set to 0 again so it doesn't heap up and make it do stuff it shouldn't.

Note that this will also make it affect spells. Let me know if you'd like to avoid that or not.

TRIG
    Events
    Conditions
    Actions
        Set DmgDealt = (Damage taken)
        Unit - Set life of (Triggering unit) to ((Life of (Triggering unit)) + DmgDealt)
        Unit - Cause (Triggering unit) to damage (Damage source), dealing DmgDealt damage of attack type Spells and damage type Magic

use this one

only 1 variable needed to make it more efficient

variabletype: real

 

[DsD)Core(]

I actually used only 1 variable, I just forgot to remove _round and _total behind it since I copied it from my own map lol >.> Thanks for pointing that out.

But your trigger does cover something that I forgot about, and that is giving the life back to the attacked unit. However, the attacked unit can still die from the attack this way, if the damage done is more than their current health. We'll need to make a workaround for that.

 

[Emu.Man00]

ugh yeah i only need it for attack, not spells and a work around for the death thing would be very nice o.o

 

[DsD)Core(]

Alright, it's going to be alot of work for me to work everything out for you so I'm going to give you some pointers in the hope that they get you going.

The first thing, to make sure it's not going about a spell, is to make a condition ((damage source) equal to (event response - casting unit)) equal to false. Now it's noteworthy that you'll probably have to add every spell triggered to this trigger if unit starts the effect of an ability, which is going to be alot of work. I'm not even sure if that would work, but as I'm not a professional and you don't have your answer yet, I will tell you as much as far as I can go with what I know.

Then, next, the dying prevention thing. A cheap workaround would be to make a period event that checks if the last damage done of a unit is equal to or bigger than the current health of the targeted unit. If so, the unit is healed on the event unit is ATTACKED (not takes damage) by the last amount of damage done. Then, later, this amount should be corrected by the actual damage that was done. Another event, if the attack is cancelled, should remove the added life again, to prevent abuse to heal a unit by a-s-ing.

That would be a general picture. But someone would have to give you a more specific answer, since I honestly don't know how to do this exactly.

I hope you get it.

 

[Emu.Man00]

Alright thanks for all your help, ill try to work on that
+rep for you

also, can i put all the actions into an if statement, making it

If ((damage source) equal to (event response - attacking unit))
Then [actions]
Else do nothing

Would that work?

 

[DsD)Core(]

I think that would be a valid solution, yes. Note that you do need to add the unit attacks event somewhere and add it as an event or condition to this trigger. That event response won't come from nowhere.

 

[Emu.Man00]

so i add that as an action in the first trigger? like this?

Trigger - Add to Backfire <gen> the event (Unit - A unit Is attacked)

And another thing came up while testing, i want it to start when i cast a spell so i did this

Trigger - Add to Backfire <gen> the event (Unit - (Target unit of ability being cast) Takes damage)

and that didnt work, so is that the problem, or is it in the other trigger when it refers to "triggering unit"?

 

[DsD)Core(]

The problem is, if you add the unit is attacked event, it wont count as a condition for the damage taken being physical, it just makes two events instead of one for which the damage catcher can trigger. That's not what we want in this case. Maybe it would be an idea to put an attacking unit into a variable and then you can actually add a condition to the damage catcher that the unit must be in the unit group that you've put the attacking unit in. Make sure they're always removed afterwards, so the attacking unit cannot attack first and then cast a spell because it is already in the group anyway.

Does that make sense?

 

[Emu.Man00]

Yeah, ill try that but do you have a solution the second part? >.< that is quite a big problem

 

[DsD)Core(]

What exactly do you want a solution for?

 

[Emu.Man00]

another thing came up while testing, i want it to start when i cast a spell so i did this

event-unit finishes casting an ability
condition-ability being cast equal to backfire equal to true
actions-trigger - add to backfire <gen> the event (unit - (target unit of ability being cast) takes damage)

and that didnt work, so is that the problem, or is it in the other trigger when it refers to "triggering unit"?

:d

 

[DsD)Core(]

The target unit of ability being cast is an event response and will be reset after a short amount of time. You'll see to use a unit variable and add it to that. Then the data won't be lost and you trigger might just work.

You'll need to store the damage done.
Two triggers needed, one to catch a unit and add it to your damage taking event.
The other, the damage taking event.

Unit Catch

Unit Catch
    Events
        Unit - A unit enters (Playable map area)
    Conditions
    Actions
        Trigger - Add to Dmg Catch <gen> the event (Unit - (Triggering unit) Takes damage)

Dmg Catch
Globalsys dmg catch
    Events
    Conditions
    Actions
        Set DmgDealt[(Player number of (Owner of (Damage source)))] = (DmgDealt[(Player number of (Owner of (Damage source)))] + (Damage taken))
        Unit - Set life of (Damage source) to ((Life of (Damage source)) - DmgDealt[(Player number of (Owner of (Damage source)))])
        Set DmgDealt[(Player number of (Owner of (Damage source)))] = 0

And you can add a condition to check if the damage taking unit has the ability.

not MUI is MPI tho

 

[DsD)Core(]

I assumed you'd only have one hero per player. To make it MUI, you'll need to add a unit array elsewhere and systemize it a little differently so that it properly catches per unit. Meh.

 

[Emu.Man00]

Nope, only one hero per player (the spell would only be castable on heroes)

 

[THE_X]

well then use what he said it will make things more easy :thup:
