what really does CreateGroup() do?

[JeffreyQ]

if i type the below code:

• Custom script: set udg_tempGroup = CreateGroup()
• Unit Group - Add (Target unit of ability being cast) to tempGroup
• Unit Group - Remove all units from tempGroup
• Custom script: call DestroyGroup(udg_tempGroup)

1. Is this MUI? Assuming each time i cast a spell i do this.
2. Does it create an object of the tempGroup? If so am i using it correctly?

Some Other Questions:
1. Why can't hashtable save Ability? When i press it will crash.
2. I base my spell on Frost Nova. When i change the Order String - Use/Turn On to chainlightning and order unit to cast chainlightning. It didn't work. What am i doing wrong?

1. 100% MUI
but not necessary, read below
2. No it doesnt create anything as always the first unit group is auto created as this is none arrayed, no need to create but if it is arrayed tempgroup[1] will be auto created but you have to create [2] and so on

1. because hash got some issues
2. just dont do it, find the other one instead

What?

Some spells bugg when you change order id, use channel as base spell works everytime you change order id (Best base spell for spell making imo)

doesnt the first group is always created?

You simply can't change the id.
It only works for spellbook and channel,
because both have a special field for this.

Thanks for ID clarification. +Rep.
Still really not clear about CreateGroup() as there are two answers @@.

 

[Justify]

CreateGroup() creates a new group handle.
Everytime you use it, this happens. GUI automaticly
creates it's group and there is most times no reason to
destroy them.
