Save/Retrieve Location/Point of units in a Hashtable

[nahuelq94]

Hi! I just a have a simple question: is there a more direct way to save/retrieve the Point/Location of a unit or this is the only way?

• Unit Group - Pick every unit in AOEGroup and do (Actions)
  • Loop - Actions
  • Hashtable - Save (X of (Position of (Picked unit))) as (Key (Picked unit)) of 0 in MyHashtable
  • Hashtable - Save (Y of (Position of (Picked unit))) as (Key (Picked unit)) of 1 in MyHashtable
  • Unit - Move (Picked unit) instantly to (Center of (Playable map area))

• Unit Group - Pick every unit in AOEGroup and do (Actions)
  • Loop - Actions
    • Set X = (Load (Key (Picked unit)) of 0 from MyHashtable)
    • Set Y = (Load (Key (Picked unit)) of 1 from MyHashtable)
    • Set Point = (Point(X, Y))
    • Unit - Move (Picked unit) instantly to Point

This is part of a trigger ability that im trying to do. Should i erase/clean the hashtable at the end? The content is irrelevant for future executions of triggers, but i failed to find the function to do this.

Any hint is appreciated since Im a total newbie

Thanks in advance.

You can save a location. There should be a hash table action to save/load a location handle.

You have two Actions for clearing a Hashtable (and more when using Jass):

• Actions
  • Hashtable - Clear (Last created hashtable)
  • Hashtable - Clear all child hashtables of child (Key (Picked unit).) in (Last created hashtable).

The first wipes the entire Hashtable, not a good if you have other important data being stored.

The second is likely what you want since it clears a Parent key.

But it's function name is misleading and has a typo. It doesn't clear all "child hashtables of a child", it clears all child keys of a parent key:

• Hashtable - Clear all child Keys of parent (Key (Picked unit)) in (Last created hashtable).

^ It should really say something like that.

[General] - clearing leaks on hashtables in GUI

how do you clear leaks on hashtables in GUI (need the code in custom scripts to clear parent, child and specific hashtables)? if i save points in hashtables how should i clear the leaks on em ? (should i save just the x,y values of the point instead? should i clear hashtables before...
