[Solved] Trigger to turn off chemical rage type spell prematurely

[WarCortez]

I have a spell based on chemical rage that morphs the hero temporarily. However, as it turns out, map transition renews the ability's timer making it last practically forever with constant map transition. Is there a way to end it via trigger?

 

[Duckfarter]

Remove the chemical rage ability before the unit-type is saved/cached but after saving its abilities.

 

[Chaosium]

Blizzard uses this in the Rexxar campaign right before performing a map transition

• Unit - Remove All buffs from (Triggering unit)

That had some weird effects. It didn't remove the buff just the timer. However, it did seem to remove the demon hunter metamorphosis. But isn't the DH ult works on the same principle as chemical rage?

 

[Chaosium]

I would've thought so yeah. Perhaps the "remove specific buff" function would get rid of it, but it might just be one of those abilities that don't obey the laws...

I think replacing the hero with the same unit type and transfering items would solve the issue completely albeit could pose additional challenges

Maybe that would require a complete overhaul because the morphing seems to messing with trigger given abilities.

Use Metamorphosis instead of Chemical Rage, trigger any extra effects you may want.

Yes, I tried that. However, it removes every spell from the ability choice spellbooks. From what I've read, it's tied to a lack of spell permanence which happens during morphing. I'm trying to tinker with that but I don't get that script.

 

[Chaosium]

Pardon my JASS but I think the function looks like this

• Custom script : call UnitMakeAbilityPermanent(GetTriggerUnit(), true, AbilityID)

Where you can replace GetTriggerUnit() by a variable if your hero is stored in there (for example udg_MyHero) and you need the rawcode of your spell between ' ' for the ability ID

The ability has to be all the ability I want to be permanent? It's a bit tricky because I have 4 spellbooks, 4 placeholder abilities and each spellbook has 2 dummy abilities and by clicking on them, you learn the real ability via engineer upgrade. So, I wonder what are the stuff I need to place to the ability ID.

What version are you using? Do Blz natives work for you?
This is what I use to cancel abilities, although I use it as an event response so I re-wrote it now to take arguments instead of GetTriggerStuff.
That being said, you may not be interested in the mana refund aspect, but I think that is simple to remove if you want to.

2 things I have to point out:

1. This is not good for item abilities
2. Almost all of my use of this has been with Channel based abilities, so I would test it to be safe.

If I wrote this for the first time today, I probably would have named my variables and functions differently, feel free to change those, you probably will want to...

I'm on 1.26 and I have practically no clue about JASS. However, it turned out that the morphing's messing with triggered abilities is a bigger issue than the buff removal because all of the hero's abilities are added via trigger.

 

[Pyrogasm]

The method described here is the same one I suggested in one of our first PM threads. Same logic applies: only has to be done to each ability once after it is added (and it sounds like you know exactly when each ability is added since you’re doing it yourself?).

It seems to work now but the spellbook made things tricky because it should disappear upon choosing ability and the unit got it back during morphing and after turning back.
