[Trigger] adding a unit to a null unit group in a hashtable

[diosilva16]

if i do

• Unit Group - Add unit to (Load x of y in hashtable)

and haven't yet stored a unit group in that key, does it create a group and store it there or does it do nothing because it didn't find a group there?
if it's the second case, how do i create and store an empty group in a hashtable

It does not create a group automatically.

->

• Custom script: call SaveGroupHandle(udg_yourHashName, parentKey, childKey, CreateGroup())

For future-reference, nothing is done automatically in Warcraft III
The only thing that's done automatically is the initialization of arrays to 0, null, "", and false.

And any time you expect something from Warcraft III, it crashes you
You'd think it'd move units inside the map bounds when they're out of it, but it doesn't do that, it just crashes you because it failed to render the frame.
If you expect a normal variable in Jass to have a default value like arrays, it crashes you.
If you create an infinite loop, it doesn't stop it, it crashes you.
If you destroy a null image, it crashes you.
If you refer to Player 22 or Player 19923, it crashes you.
If you refer to Player -1, it crashes you.
If you set a unit's teamcolor to something greater than 15 or less than 0, it crashes you.

Thus, you should NEVER expect Warcraft III to do things for you

If you create an infinite loop, it doesn't stop it, it crashes you.

that isn't true, at least in GUI. triggers cease to run after a depressingly short number of functions

this

• Untitled Trigger 004
  • Player - Set Player 1 (Red) Current gold to 0
  • For each (Integer A) from 1 to 10000, do (Actions)
    • Loop - Actions
      • Player - Add 1 to Player 1 (Red) Current gold

gives me 3060 gold

^That is not an infinite loop, it just hits the operation limit

This is causes an infinite loop and crashes the game:

• Untitled Trigger 016
  • Events
    • Unit - Knight 0018 <gen> Takes damage
  • Conditions
  • Actions
    • Unit - Cause (Triggering unit) to damage (Triggering unit), dealing 500.00 damage of attack type Spells and damage type Normal
