Damage Target, Drain Mana and Stun

[Templarion]

I am trying to create a basic vampire ability: Feed.

Feed damages target, drains its mana and stuns it until vampire decides to stop drinking the blood - or the victim dies.

I am kinda confused how should I do this. I am not very familiar with Triggered Abilities but I sure do know how to create triggers.

First I thought I should create Feed using "Channel" ability but I noticed that I cannot Add Buffs via triggers (or can I???). I also noticed that there is Siphon Mana ability which is very confusing. I even read the tutorial which explains it but it still keeps confusing me (especially the buffs: "drain mana & life, drain mana, drain life, drain mana (target), drain mana (caster)...). If I cannot add Stun using triggers should I use Bash or something like that as a base ability?

How should I do this? What ability should I use as a base and what should I do with triggers?

Reputation will be awarded for helpers - of course.

        Set Duration = 0
        Unit - Unpause Target
        Unit - Set Target movement speed to (Default movement speed of Target)

base the ability Feed from Aerial Shackles

Base it of mana drain. Then have a dummy unit cast a spell that stuns like hurlbolder or something. There you can do damage aswell or just simply have the dummy hit the unit if you want the damage to be done over time. And when he stops casting the manadrain you have a trigger that removes the stunbuff and you are done. Just make sure that the manadrain and the stunbuff has the same duration and starts about the same time and you are all set:thup:

Here is also a thread with a map attached to one of my posts. It is based on lifedrain tho but that is easely changed

This is what I call a good service!

Thank you very much, XeNiM666. This reputation I give you is well earned!

I'm sorry to say this but XeNiM666, your trigger doesn't work completely the way I wanted. Anyway, you helped me a lot because you pointed me the way I need to go.

Here are the problems:
Firstly, the original trigger (made by XeNiM666) kills the victim instantly - vampire cannot decide the amount of blood drained.
Secondly, when "Wait" is added to the trigger the target can move - even it should not be possible.
And in the end, I started to think would this trigger work IF there are multiple vampires drinking several different (or the same) targets at the same time.

Here is the broken trigger I am trying to make working at the moment:

Feed
    Events
        Unit - A unit Begins casting an ability
    Conditions
        (Ability being cast) Equal to Feed 
    Actions
        Set AbilityFeedCaster = (Casting unit)
        Set AbilityFeedTarget = (Target unit of ability being cast)
        Unit - Pause AbilityFeedTarget
        Unit - Set AbilityFeedTarget movement speed to 0.00
        For each (Integer A) from 1 to 10, do (Actions)
            Loop - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        (AbilityFeedTarget is dead) Equal to False
                        AbilityFeedDuration Less than 10
                    Then - Actions
                        Unit - Set life of AbilityFeedCaster to ((Life of (Casting unit)) + 20.00)
                        Unit - Set life of AbilityFeedCaster to ((Mana of (Casting unit)) + 20.00)
                        Unit - Set life of AbilityFeedTarget to ((Life of (Target unit of ability being cast)) - 20.00)
                        Unit - Set life of AbilityFeedTarget to ((Mana of (Target unit of ability being cast)) - 20.00)
                        Special Effect - Create a special effect attached to the chest of (Target unit of ability being cast) using Abilities\Spells\Other\Stampede\StampedeMissileDeath.mdl
                        Special Effect - Destroy (Last created special effect)
                        Set AbilityFeedDuration = (AbilityFeedDuration + 1)
                        Wait 0.30 seconds
                    Else - Actions
                        Set AbilityFeedDuration = 0
                        Unit - Unpause AbilityFeedTarget
                        Unit - Set AbilityFeedTarget movement speed to (Default movement speed of AbilityFeedTarget)
                        Skip remaining actions
        Set AbilityFeedDuration = 0
        Unit - Unpause AbilityFeedTarget
        Unit - Set AbilityFeedTarget movement speed to (Default movement speed of AbilityFeedTarget)

Someone, please, help me to make this ability work.

 

[Marsmallos]

Do you want him to both drain life and mana? And what colour do you want the drain effect to be? (green = drain life, or blue = drain mana).

How long is the full duration of the feed? (Like, what is the maximum length the vampire can feed in seconds?)


EDIT: not sure if this is what you wanted but I did a very simple Feed spell:

Feed
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Feed 
    Actions
        Set Feedtarget = (Target unit of ability being cast)        Set Feedtarget_location = (Position of (Target unit of ability being cast))
        Unit - Create 1 Dummy unit Feed stun for (Owner of (Casting unit)) at Feedtarget_location facing Default building facing degrees
        Unit - Add a 3.00 second Generic expiration timer to (Last created unit)
        Unit - Order (Last created unit) to Human Mountain King - Storm Bolt Feedtarget
        Unit - Hide (Last created unit)

If the spell is cancelled

Feed cancel
    Events
        Unit - A unit Stops casting an ability
        Unit - A unit Finishes casting an ability
        [COLOR="Red"](I am not 100% sure wich one of these events are the right one so I added both, but it works fine)[/COLOR]
    Conditions
        (Ability being cast) Equal to Feed 
    Actions
        Unit - Remove Feed (Stun) buff from Feedtarget

I got a Vampire hero with the ability "Feed" based of the Dark Rangers Life Drain, that has been edited to drain both life and mana (You can easily do this in the object editor).
I also got a dummy unit called "Dummy unit Feed stun" with the ability Locust (to make him untargetable and not appear on minimap) and "Feed stun effect" wich basicly is a Mountain King - Storm Bolt without mana cost, with its stun duration set to the same amount of time as the max duration of Feed. The storm bolt doesnt have a missile and missile speed is set to 0 and Hero Ability = false. The buff the storm bolt applies I renamed to "Feed (stun)" just for the fun of it.

How the trigger works:

The hero casts Feed on a target, and the dummy unit "Dummy unit Feed stun" gets created at the location of the target, and does stormbolt on him to stun him. The expiration timer ensures that the dummy unit gets removed from the game.
If the hero cancels casting feed, the second trigger detects this and removes then "Feed (stun)" buff from the target, and the target is no longer stunned.

Hope I helped!

Thanks a lot. This helped.

I edited it little but the code is yours. Therefore you will get some credit, too. (+rep!)
