[General] Set ability remaining cooldown to certain value?

[Astrella]

Hi everyone,

was wondering if there is a way to set the remaining cooldown of an ability for a unit to a certain value. Specific usecase:

Custom ability being cast, say it has 10 second cooldown, if the target is invalid (determined in a trigger) I want to be able to set the remaining cooldown of the ability to a small value, say 0.5, rather than fully reset it to prevent players from being able to just mash the ability.

Unit - For Unit (Triggering unit), Set cooldown of ability Big Bad Voodoo, Level: 0 to 5.00


just type "cooldown" in the "search for" bar in actions. pops right up.

Native functions were recently added to support adjusting ability cooldowns. If they work correctly or can do what you are after I am not sure.

If you are using a legacy version of Warcraft III then you might be able to work around the issue by detecting the target before the ability goes onto cooldown and if so interrupting it. For example when the player orders the unit cast the ability you could already validate the target and abort the order before the unit has chances to execute it. Intercepting abilities when they "begin casting" can also allow for them to be interrupted before the ability goes onto cooldown.

This sets the cooldown of the spell for future use, not adjusting remaining cooldown.

whoops...

but what if you did that, and then after waiting the amount of time necessary - reset cooldown, and right away used set cooldown again to reset it to it's original value?

Hmm, this seemed to work, probably cause "starts the effect of ability" triggers before the cooldown applies, just annoyed that Blizzard indexing is so inconsistent about starting at 0 or 1. I haven't tried your solution yet, Ender, but I imagine it'd work as well I just always had been putting the level at 1 instead of zero. (Probably why the new natives weren't working properly for me either.)

call BlzSetAbilityRealLevelField(BlzGetUnitAbility(GetTriggerUnit(), 'A00L'), ABILITY_RLF_COOLDOWN, 0, 0.5)

Which works for my use case, I'll have to see if I can now get one of the natives to work for editing the cooldown of an ability already ticking down.

For adjusting an ability already ticking down I believe you would do it like this:

Set variable Amount = 5.00
Set variable newCd = Cooldown remaining for ability - Amount
If newCd < 0.00 then set newCd = 0.00 (probably unnecessary as I'm sure this is automatically handled for you)
Start unit cooldown for ability as newCd seconds

With these natives you should have all the tools needed to manipulate cooldowns however you'd like. They all work as well (shocker, I know).
