Detecting item ability type

[wc3neverdies]

Hello,

I need help for my map. Basically in this map every player controls a hero with 0 abilities. With an RNG system whenever the heroes pick up a specific object they learn 1 random ability. After they cast the ability it disappear. A hero can use an ability one time. I'm using this trigger to remove the ability after the cast :

• Events
  • Units - A unit finishes casting an ability
• Conditions
  • Actions
    • Set CastedAbility (PlayerNumberOf (owner of (Casting unit))) = (Ability being cast)
    • Unit - Remove CastedAbility (PlayerNumberOf (owner of (Casting unit))) from (Casting unit)

It works well BUT in this map there are items, and every time a hero uses an item it count as an ability and if the item has charges or it's a usable item (like Kil'jaden dagger) it bugs out and can't be used again.

So my question is there is a way to detect when an ability is casted with an item??
I tried disabling the triggers whenever a hero used an item, but didn't work as well.
Please tell me i dnt have to check for all abilities type one by one.

Thanks in advance

Check if unit has the ability being cast. Check if the ability's level is greater than zero on the casting unit.

THank you for the quick reply, also nice idea Unfortunately it's not working, items still bugs and can't use them after

Is the level of ability == 0 if it is on an item? If it is 0, just don't remove it.

I checked the items abilities in object editor, many of them have level 1 maybe it's cause of that, so when a hero uses an item it's considered to have that skill

See if this works, try it for items and abilities.

Thank you, this works but not perfectly. It doesn't work with channeled abilities such as blizzard, siphon mana, etc and some other that have a longer casting time.

It works on blizzard and does not depend on cast time. Create an archmage in the test map, cast blizzard and it will tell you that an item was not used. I used starts effect of the ability instead of starts casting an ability exactly to avoid cast time issues. This ignores cast time completely.

Well, i needed the ability to be removed from the unit, so i moved the ''remove spell from spellunit'' above the line where spellunit was set to none. here is the map btw

• ItemUse
  • Events
    • Unit - A unit Uses an item
  • Conditions
  • Actions
    • Set isItemused = True
    • Game - Display to (All players) the text: item used
    • Custom script: call StartTimerBJ( udg_timer, false, 0.0001 )
    • (turn this off) Countdown Timer - Start timer as a One-shot timer that will expire in 0.01 seconds

Try this. It seems there is some delay introduced when my code is ported to a map with more timers and stuff, however this should fix it, see if it works consistently now.

I tired (took me a while before getting a channeled spell) with blizzard and after the first wave the ability is removed from the unit and it stops. That's why i used - A unit finishes casting an ability. If i used - A unit finishes casting an ability - you can cast it then immediatly order the unit to move and the ability isn't removed because the hero didn't finished casting it.

Still, though, why are you even using the same abilities for items and unit abilities? Some do not even have a tooltip.

If you are using only default wc3 abilities, there is a very simple way to figure out if an ITEM ABILITY is used, but not whether it comes from an item.

• SpellEffect
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
  • Actions
    • Set spellunit = (Triggering unit)
    • Set spell = (Ability being cast)
    • Custom script: if udg_spell >= 'AI00' and udg_spell < 'AJ00' then
    • Game - Display to (All players) the text: ITEM ABIL
    • Custom script: else
    • Game - Display to (All players) the text: UNIT ABIL
    • Custom script: endif

This checks whether the item ability is used with 100% accuracy if you are only using default wc3 item abilities and ON ITEMS. Don't use item abilities on units.

 

[wc3neverdies]

Well, it's because originally there were only abilities, i added the items after, so i still have to remove the items abilities from the variable list.

Thank you for the help

Just for the record, now you need only one trigger.

• SpellEffect
  • Events
    • Unit - A unit Finishes casting an ability
  • Conditions
  • Actions
    • Set spell = (Ability being cast)
    • Custom script: if udg_spell >= 'AI00' and udg_spell < 'AJ00' then
    • Game - Display to (All players) the text: ITEM ABIL
    • Custom script: else
    • Game - Display to (All players) the text: UNIT ABIL
    • Custom script: endif
