[i_am_cuul]

"You need to actually remove stored handles inside the hashtable."

how do i go about doing this?

..bumb..

Ehh, as far as I know just with this trigger:

• Actions
  • Hashtable - Clear all child hashtables of child (Key Handle) in (Hashtable)

This will remove all values of a handle in the hashtable.

Ohh, but that's just simple leak fixing...
If you are using hashtables to store locations, you'd better store the coördinates...

I'll give you an example:

Your way (as far as I know)

• Actions
  • Hashtable - Save Handle Of(Center of (Playable map area)) as 0 of (Key (Triggering unit)) in (Last created hashtable)

OR:

• Actions
  • Set Location = (Center of (Playable map area))
  • Hashtable - Save Handle OfLocation as 0 of (Key (Triggering unit)) in (Last created hashtable)

Well, in any case: you can't remove that location since you store it.
From the moment you remove the location, the stored location will also be removed, thus the entire spell (or whatever it is you are doing) fails.
However, reals aren't removed when a location is removed, thus it's best to do something like this:

How it should be done

• Actions
  • Set Location = (Center of (Playable map area))
  • Hashtable - Save (X of Location) as 0 of (Key (Triggering unit)) in (Last created hashtable)
  • Hashtable - Save (Y of Location) as 1 of (Key (Triggering unit)) in (Last created hashtable)
  • Custom script: call RemoveLocation(udg_Location)

Now it removes the leak caused by the handle (in this case the location), while the stored data still remains.

To recall the data, simply do something like this:

• Actions
  • Set Location = (Point((Load 0 of (Key (Picked unit)) from (Last created hashtable)), (Load 1 of (Key (Picked unit)) from (Last created hashtable))))

(this can be done with the "Convert coördinates to point" function).

(If you did not know about removing leaks yet, leaks are the main cause of lag and may slow down the game or even make it crash.
Read this post to see what leaks and how to fix it).


If I am completely wrong, please explain a bit further ^^

Nope, integers/reals don't leak, they'll be erased once their values change.
