[General] How to grab nearby item?

[stan0033]

I'm trying to make triggered spell called "Grab Item" which gives the nearby item in proximity to the hero. Does soemone know how to grab nearby item? It can be random if there are more nearby items.

In GUI there is a give item to hero action, probably what you are looking for.

• Hero - Give (Random item in (Playable map area)) to (Triggering unit)

You can pick an item in a region. Problem is: Regions are no circles, but you can use matching condition to check if the distance is smaller than a certain range.

A whole functionating example with leak cleaning.

• Grap Near Item
  • Events
    • Unit - A unit cast a spell
  • Conditions
    • (Ability being cast) Equal Grab Item
  • Actions
    • Set Loc = (Position of (Triggering unit))
    • -------- Beaware that, this is a/b's total edge length. Means has half range from the center. Here 300. --------
    • Set Rect = (Region centered at Loc with size (600.00, 600.00))
    • Set Item = (Random item in Rect)
    • Hero - Give Item to (Triggering unit)
    • Custom script: call RemoveLocation(udg_Loc)
    • Custom script: call RemoveRect(udg_Rect)

For minor optimization I'd use a variable for triggering unit

Random item in rect is a rectangular area to search for items.
As there is no items in range you need to use (items in region matching distance to grabbing unit less than ...) to have an items in range function.
You could also put the distance comparison within the picked items function and let it pick the closest item.
