Random item abilities

[SpasMaster]

Hello guys!

Quick question here,

I was wondering if you could add an ability to an item via triggers...
I saw that there is no such option in the editor, but I decided to ask you if you have any ideas.

Say an item drops (via trigger). Before that I made a list with abilities.
Example: Ability 1 - Attack Speed bonus, Ability 2 - Strength bonus, Ability 3 - Health regen.

So the item drops and a trigger randomly selects one ability from the list and gives it to the item.

Any ideas?

• call SaveInteger(hash, ItemTypeID, 0, 3)
• call SaveInteger(hash, ItemTypeID, 1, 'asdf')
• call SaveInteger(hash, ItemTypeID, 2, 'qwer')
• call SaveInteger(hash, ItemTypeID, 3, 'zxcv')

• Event
• Unit acquires an item
• Actions
• set int1 = LoadInteger(hash, ItemTypeID, 0)
• if int1 != 0 then
• call UnitAddAbility(GetTriggerUnit(), LoadInteger(hash, ItemTypeID, GetRandomInt(1, int1))
• endif

The first trigger initializes the item type. The first line tells there are 3 possible abilities.
The following lines are the abilities stored for the item type.

The second trigger gives a unit a random ability.

Could you please provide a test map? I am not familiar with hastables and recreating what you just showed me seems impossible to me. I will be gratefull.

He is suggesting that you give the ability to the "picking up" unit "on pickup".

Alternately, you can create 3 different items each with an ability, and then when one item will "drop", you can randomly choose one of the 3.

In that way, each time when the unit picks the same item it will generate random ability?

The ability of the item should be generated when it drops, not when its picked up. Thats what I don't know how to do.

I think it's impossibru... you have to create three items with the same icon, name etc. but with different ability. And you know what to do next.

Здравей отново! (translated from Bulgarian to English that means kinda like this 'Welcome back!')

• Unit - A unit Loses an item

That should get you started.

When it drops, you can set the custom value of it to a random integer between 0 and 2 and choose the ability based on the custom value of the item

 

[Cokemonkey11]

Setting unit user data would be a bad idea. It's better to simply set a local integer to a random number between 0 and 2 and then replace the item with version a, b, or c

If you equip two of the same items and unequip the other, you'll lose the ability. It bugs if the ability is not stacking. For example if the item gives you Holy Light. Equip two items, unequip the other. No more Holy Light though you still have an item that grants you Holy Light. That's quite easy to fix, just save the ability id for the unit that gets the item. Use unit handle id as the parent key, ability id as the childkey and store the stack count.

well it depends on what ability you need to add to the item. . . you can store an ability when a unit drops and item and then give that ability to another unit who will acquire the item later. i dont know what you are trying to do but there is no way to add an ability to an item via a specific function in gui or jass
