[Solved] Items system related questions

[thekebecer]

SOLVED
1. I have a system that drop an item(for example a weapon) if the hero already have an item of this type.(weapon in the example). My problem is when I buy items, I don't want the buyed item to be dropped if the hero already have an item of the same type, I just want to show the alert message that say: ''Can only wear one weapon'' and I want to give back the gold that the item cost.

SOLVED
2. I've search for it but I've found nothing, is there a way to ''clear'' the item that are on the ground, for example an item is dropped, if 30 sec. later no one picked it the item disapear.

+REP for help

Ok to do this you wanna remove the bought item. Then create a dummy unit and give it 2 of the same item. Then order that dummy unit to sell those items to a shop. If you didn't understand this, or simply don't know how to do this... I'll create a map demonstrating this.
Here it is:

Is this only for find the value of the item?

 

[maddeem]

Yes, but I can also make that item removal system if you want
Hell, I'll do it now.

Is it possible to detect if an item is buy from a shop or taken from ground?

Yes, you can use these simple triggers:

• Item
  • Events
    • Unit - A unit Sells an item (from shop)
  • Conditions
  • Actions
    • Hashtable - Save True as (Key sold) of (Key (Sold Item)) in I_Hash

• Item2
  • Events
    • Unit - A unit Acquires an item
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Load (Key sold) of (Key (Item being manipulated)) from I_Hash) Equal to False
      • Then - Actions
        • Game - Display to (All players) the text: This item is picked.
      • Else - Actions
        • Game - Display to (All players) the text: This item was sold.

Test map attached; you can drop the bought/picked items and it will still tell you whether this item was sold or picked up by your unit.

Indeed ^^ Keep up the good questions

Thanks Pharaoh_ it's looking good, just one thing, when I drop a bought item and I picked it after it's say tht it's a buyed item, is it possible to remove it?

 

[Pharaoh_]

Of course it is possible, just add this trigger:

• Item 3
  • Events
    • Unit - A unit Loses an item
  • Conditions
    • (Load (Key sold) of (Key (Item being manipulated)) from I_Hash) Equal to True
  • Actions
    • Hashtable - Clear all child hashtables of child (Key (Item being manipulated)) in I_Hash

 

[thekebecer]

I will try this when I got some time, htanks for help

EDIT: I used what you send me, thanks you two. +REP
Can you help me with the second questions?

 

[Adiktuz]

• Create a hashtable
• When an item is dropped, save 30.00seconds as a real on the hashtable using the item's handleId as the parent key, the child key could just be 0
• Add the item into an array
• Create a .03 seconds periodic trigger which loops through the array, and reduces the saved real by .03 seconds
• Now, if the real becomes less than or equal to 0, remove the item
• Then if an item is picked-up, remove it from the array, recycle the index, and also flush the child hashtable specific to that item

 

[thekebecer]

I have some problem about understanding hastable, can you make me a little demo of this?

 

[maddeem]

Yo... I did this in my second post...
xD

That removes items that are on the ground and that haven't been picked up for 30 seconds.
The time can be changed to whatever you feel like.

 

[thekebecer]

Oh thanks a lot., I added you in the Help section of my map.
