Upgrading items

[Ham]

hey guys i've seen some maps where you can upgrade items, such in troll tribes, and 300, i'd like to know what's the trigger for when an unit has exact item cast ability and make it either cost gold/lumber or requiere another item (like morphing two items into one) such dota. anyone could help me create this trigger? rep+ to whoever helps

 

[toofless]

event - unit aquires an item

condition - item being manipulated is item1 or item2
condition - unit has item1 in inventory and unit has item2 in inventory

action - remove item1
action - remove item2
action - make item3 and give to triggering unit

i think there's a tutorial about this

• Sword
• Razorspine
  • Events
    • Unit - A unit Acquires an item
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (((Hero manipulating item) has an item of type Sword) Equal to True) or ((Unit-type of (Triggering unit)) Equal to Dummy)
      • Then - Actions
        • Item - Remove (Item carried by (Hero manipulating item) of type Sword)
        • Hero - Create Swordx2 and give it to (Hero manipulating item)
        • Special Effect - Create a special effect attached to the origin of (Triggering unit) using Abilities\Spells\Items\AIem\AIemTarget.mdl
        • Special Effect - Create a special effect attached to the origin of (Triggering unit) using Abilities\Spells\Items\AIlm\AIlmTarget.mdl
        • Special Effect - Create a special effect attached to the origin of (Triggering unit) using Abilities\Spells\Items\AIim\AIimTarget.mdl

      • Else - Actions
        • Do nothing

that what i use if here is some problems i hope other guys will fix it

First, why are you using if-then-else if u don't need to?

Your condition is inconsistent because of the 'or'. I'm assuming you want to add swordx2 only if unit has sword? At the moment the trigger is giving swordx2 to your hero (dummy?) when it aquires ANY item because the 'or' makes the trigger ingnore your first condition if the hero getting an item is Dummy. Replace 'or' with 'and'.

Remember to clean up and Special Effects you use. They are persistent and stay unless you trigger to remove them. I don't do this often so I don't know but maybe if you add an expiration to each effect that will clean them up nicely.

well im not quite sure but this works on me ^^ so i dont care

 

[toofless]

Ah ok, it would because the if-then-else states all conditions must be true. Missed that.
You effects aren't too bad because you won't be making the trigger run hundreds of times. Still better to clean up your effects.

This is the trigger I'm using for my map:

• Barricade
  • Events
    • Unit - A unit Acquires an item
  • Conditions
    • ((Triggering unit) has an item of type Barricade_Items[1]) Equal to True
    • ((Triggering unit) has an item of type Barricade_Items[2]) Equal to True
  • Actions
    • Item - Remove (Item carried by (Triggering unit) of type Barricade_Items[1])
    • Item - Remove (Item carried by (Triggering unit) of type Barricade_Items[2])
    • Hero - Create Barricade and give it to (Triggering unit)

Barricade_Items[#] is a variable that is set to the 2 items that create the barricade.
This trigger automatically creates the item. DOTA has a third item (so I'm told) and thats just an item to ensure that you can create the item (I believe its a recipt, but then again, I don't play DOTA).
To check for resources, in conditions, add "Player #'s current (resource) is greater then or equal to (cost)" then just add "Add -# to Player #'s current (resource)". Basically, that adds negative resources (takes away) only if the player can afford it. If you need clarification, I could give it to you.

ok that's pretty much about combining items, but now what about upgrading items? using gold / lumber (or even mp / hp)

 

[idodik]

In the case of upgrading via mana use a mana ability and use the event "A unit uses item".
In the case of upgrading via resources I think the "ivory tower" ability will do thus.

 

[toofless]

Same principle man.

Check whether the unit getting the item has previous item if so remove it and add a new upgraded item. Then take away all cost like gold/lumber is easy.

HP/MANA just do set units hp/mana to ((triggering units hp/mana) - cost).

Have you read the tutorial by toolbox? How to make item recipes
