Cooldown Reset Help

[nafre]

Is there a way to reset cooldown for only 1 skill. I would like it in a custom code and instructions on how to use it.
P.S. Im not sure how to use Jass.

I'v done this in the past with the Add Ability/Remove Ability triggers. You make an integer which will detect at what lvl your spell is and if a cooldown reset activates you remove and then add back the spell and set it to its apropriate level via the options in the 'hero' triggers.

It's easier if it is not hero ability. Just remove it and add it again. Use timers and stuff if needed.

You mean i remove the abilities which i do not want to reset cooldown and then use the reset cooldown trigger and add those skills which i removed back again?

Edit: i already tried it and it lagged the game everytime this trigger is used. Is there another way to do this or can you show me an example.

You remove the ability you want to refresh, not the other abilities. Removing an ability from a unit refreshes its cooldown.

I'm sorry but i forgot to mention that the ability is a hero ability.

• Refresh Ability
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
  • Actions
    • Wait 0.00 seconds
    • Set Ability = (Ability being cast)
    • Set AbilityLevel = (Level of Ability for (Triggering unit))
    • Unit - Remove Ability from (Triggering unit)
    • Unit - Add Ability to (Triggering unit)
    • Unit - Set level of Ability for (Triggering unit) to AbilityLevel

AbilityLevel is Integer variable
Ability is Ability variable

But beware, this only works for single-cast spell such as Banish, Storm Bolt and others
You have to self-adjust the event to "A unit Finishes casting an ability" if the spell such as Flame Strike (requires a cast delay time)

Don't worry about the 0.00 second of wait there, it is still MUI and without it, the trigger will bug (the event occurs too fast), therefore putting a wait there is required.

defskull, have you tested that? Removing the wait should not bug it, as removing an ability after casting it is common practice for dummy abilities.

 

[nafre]

ok thx. I get it now. I just have to try it.

This works perfectly for me:

function ResetCooldown takes unit whichUnit,integer whichAbility returns nothing
    local integer level=GetUnitAbilityLevel(whichUnit,whichAbility)

    if level>0 then
        call UnitRemoveAbility(whichUnit,whichAbility)
        call UnitAddAbility(whichUnit,whichAbility)
        call SetUnitAbilityLevel(whichUnit,whichAbility,level)
    endif
endfunction

It basically abuses a WC3 bug, where removing an ability from a unit/hero will remove the cooldown as well, so removing it and adding it back imediately will reset its cooldown.

Usage:

• Custom script: call ResetCooldown(GetTriggerUnit(),GetSpellAbilityId())
• Custom script: call ResetCooldown(udg_MyGlobalVariable,udg_MyAbility)
• Custom script: call ResetCooldown(udg_MyGlobalUnit,'A000')

I always test something before I post it, believe me.

You should test it, you should test it....

A Blood Mage cast Banish to himself (using my trigger, just remove the Wait), I wanna see did it work or not, try it.

Custom script: call ResetCooldown(GetTriggerUnit(),GetSpellAbilityId())
Custom script: call ResetCooldown(udg_MyGlobalVariable,udg_MyAbility)
Custom script: call ResetCooldown(udg_MyGlobalUnit,'A000')

You sure JASS has function like that ? 'ResetCooldown' ?
Why I kept getting errors "expected a function name", proves that this function does not exist ?

I have this and kept getting errors;

• Melee Initialization
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
  • Actions
    • Custom script: set udg_AbilityID = GetSpellAbilityId()
    • Custom script: call ResetCooldown(GetTriggerUnit(), udg_AbilityID)

heh, I believe you man. Was just asking.

Perhaps it has something to do with the fact that dummy units are typically ordered "issue order targeting ___" and then the ability is removed to trigger that "instant" glitch/abusation.

Also, about this part:

You have to self-adjust the event to "A unit Finishes casting an ability" if the spell such as Flame Strike (requires a cast delay time)

You should be careful because not every ability behaves like flame strike (which is a rather strange one, actually)

 

[defskull]

Have you always remove the ability once your dummy has casted it ?
For what reason, actually ?

Hmmm, perhaps dummy unit settings are:
Art - Animation - Cast Backswing: 0
Art - Animation - Cast Point: 0

Making them almost instantly to cast the spell without animation delay

All units have animation delay, but if your dummy is none.mdx model, perhaps it does not have any animation to play, that's why almost instantly

This is just pure guess by the way

 

[Cokemonkey11]

Nope, works for any unit. Try adding storm bolt to a footman

add ability, order ability, remove ability.

There is a glitch/abusation that causes it to cast instantly (this is common practice)

 

[defskull]

Does a test map is required to make you believe ?

After you test the map, go to Trigger Editor and add Wait of 1.00 second above the Remove Ability function and see now that will work

But if it's instantly, the Footman unable to do anything since it requires him a cast animation.

I'll take your word for it mate
