How Give Unit Buff & Debuff After Casting A Spell

[Griffen25]

Hello All, thank you for taking the time to help somebody out, any information will be much appreciated =]

ok, now 'The Problem' is i have a unit "Drunken Wood Chopper", basically i want this unit to cast a spell (Drink), and gain the buff Beserk (orc), and the debuff Curse (Undead).

I have tried editing spells to award these buffs but it gets messy and the end result is always the same, i was hoping that somebody could suggest a code to Help. I usually operate upon the lines of...

Drink[SIZE="1"];[/SIZE]
[U]Events[/U]
Unit - A unit Begins casting an ability
[U]Conditions
Action[/U]
[B]If [/B]((Ability being cast) Equal to Drink) [B]then[/B] do ([COLOR="Red"][SIZE="3"]???[/SIZE][/COLOR]) [B]else do[/B] (Do nothing)

I Was Hoping that somebody could help me fill in the gaps, because i was unable to find an action that works something along the lines of
Actions
"Unit - Add Buff (Beserk)"
"Unit - Add Buff (Curse )"

Thank You =]

Create a dummy and force them to cast a spell on your unit, this will add a buff.

As for remove buff:
unit - remove specific buff.

Thank You For your input

I will try this right away!
*15min later*
Can you please elaborate a little about the dummy? i'm a little unsure about how to do this, i know it has something to do with 'arrays' but i'm not sure how to make them cast the spell and how to properly set up the array

You don't need to use arrays to use dummies.

Just make a copy of any unit in the object editor.
Set model to None.mdl (manually)
Set shadow to none
Add the ability Locust (to make it unselectable and untargetable)

Add the ability you want it to cast either in the object editor or in the trigger, and make it cast it on your unit.
On the next line in the same trigger, add a few seconds expiration timer to the dummy unit so it will be destroyed after it has cast the spell, but not right away.

Hope that makes it somewhat clearer

thank you, i feel as though i am almost there,
i have created the invisble unit,
however i am unclear about how to make the invisible unit unselectable
but more importantly, i am unsure about how to make him cast spells like beserk who when activated target the caster by default.
thank you deerly for your assistance! =]

In the unit's list of abilities in the object editor add the ability "Locust" to the dummy unit.

Think like this:
What does beserk give...?
Attackspeed bonus... You take more damage... Movementspeed increase...
There isn't any spell which can target an unit with those things....
So 2 options:

• Add 2/3 effects using an ability (add an ability to your unit instead of buffing), and the 3rd effect will be your buff.
• Force your unit to cast beserk (not always possible since this interupts his order)

you could use bloodlust if you dont need the damage taken increase

He already told you.

Don't make the unit invisible.

Go to unit model and change whatever the model is to .mdl in the bottom part of the selection where there is text in there that you can modify. And remove whatever shadow it has. This already makes it "invisible". The problem with using invisibility is that if the unit is paused, the invisibility wears off if I think.

Next, go to Spell Animation Backswing and change it to 0.000. Do the same for the Spell Animation Cast Point. It should be called something like that. It's near the to under I think Animation - Backswing and Animation - Cast Point.

Next, in the abilities section go to the L area and look for "Locust". It automatically makes a unit unselectable and invurnerable. I forgot if setting the unit model to .mdl makes it invurnerable, but whatever, do this anyway.

Next, make the "Drink" spell based off of "Beserk" (this is the simplest way but probably only saves 30-60 seconds). Modify the numbers to what you want them to be.

Next, make a "Drunk Miss Effect" spell based off of "Curse". Modify the numbers to what you want them to be. (NOTE: Your duration (secs) should be the same for "Drink" and "Drunk Miss Effect" or else one effect will outlast the other.)

Now, you can add "Drunk Miss Effect" to your new dummy unit if you aren't going to have too many dummy spells. If you do, don't add it and use the trigger editor to add it.

Now for the triggered part. If you followed all the instructions above, you should have everything set up.

Now, I'm not going to waste time to copy and paste the whole thing for you, so I'm just going to outline what you have to do.

Create a variable: [Temp_Point] - Stores point on map (location)

-Events - Unit STARTS THE EFFECT OF AN ABILITY <---- Very important, otherwise they can stop casting before the ability's effect takes place and end up with the "Drunk" effect without the beserk effect. But since Beserk's casting can't be stopped by ordering him to do something else, you will be fine in 99% of cases. The last 1% is if they order the unit to stop before the effect goes off.

-Conditions - Ability being cast is "Drunk"

-Actions - Set [Temp_Point] to location of [Triggering Unit]
-Actions - Create [Dummy Unit] for [neutral passive] at [Temp_Point] facing...
-Actions - Give ability [Drunk Miss Effect] to [last created unit]
-Actions - Order [last created unit] to order targeting unit [Banshee - Curse] [Triggering Unit] <----It's something like that, I forgot the specific thing for it, it might be "Undead- Curse"

You can do 2 things for this next one, I will list them both.
*-Actions - Kill [last created unit]
*-Actions - Add expiration timer to [last created unit] for [0.01] seconds

-Actions - Custom Script: call RemoveLocation(udg_Temp_Point) <----It must say "call RemoveLocation(udg_Temp_Point)" EXACTLY! This will remove the leak caused by leaving the variable Temp_Point around. Of course, don't type in the ". Basically this reduces lag that could be caused by running this trigger hundreds of times.

That should cover it. If you still have problems... I'll look it over. If there's nothing wrong with this setup, figure it out yourself because this has so much explaination that you would have to be blind or an idiot to not understand it.

And for you to have gone the way you did, is kind of stupid to start with... Just had to say it... Even for a beginner, it was... Yeah... You get the point...

Custom Script: call RemoveLocation(udg_point)

Just Hide last created unit =.=. No need all the locust thing (unless it is really necessary, but in your case, i think hiding would be enough).

Untitled Trigger 001
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to YourAbility
    Actions
        Unit - Create 1 Footman for (Owner of (Triggering unit)) at (Position of (Triggering unit)) facing Default building facing degrees
        Unit - Add Unholy Frenzy to (Last created unit)
        Unit - Set level of Unholy Frenzy for (Last created unit) to (Level of (Ability being cast) for (Triggering unit))
        Unit - Order (Last created unit) to Undead Necromancer - Unholy Frenzy (Triggering unit)
        Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
        [B]Unit - Hide (Last created unit)[/B]

This will give the buff. The Footman will be your dummy. As for the dummy ability (the Unholy Frenzy) use Bloodlust instead if you want to increase attack speed and movement speed (but not damage taken, there is no targetting spell for this).

Sucess! but could use some fine-tuning

Thank you very much Oreo_clan, much appreciated advice, i decided to use your idea with a slight twist, i found a small problem. Once i had everything set up i noticed that my target was only receiving the Debuff (Curse) & not the buff (Berserk). I figured this was because a neutral creep can not cast a buff upon an enemy,
I decided to make the trigger for my spell the berserk spell (renamed 'Drink') and once the game detected that this was casting it would create a dummy unit and curse the target.

This is exactly what i wanted, however i am unable to fine tune the whole mechanism. Once the unit has received both the buff & debuff, i would like to enter in my own custom text, rather then "This unit has been cursed it has a chance to miss attacks". However if this is not possible, its no fatal problem.

Secondly i have encountered a minor problem with the custom script you have supplied me with. i was wondering if u might have an answer as to why i am being fed this error message?. (In attachment)

Thank you very much for your support and most of all patient.
