Unit Group Arrays

[NoBodyIsHere]

So when we're clearing up unit groups, we clear them using the DestroyGroup(udg_...) script, which as far as I understand, releases the group from its referencing variable. For unit group that has array data, does this only clear the data with the specified array value (1, 2, etc.), or does it clear the entire unit group (TempGroup)?

Group[0] is its own unit group
Group[1] is its own unit group
Group[2] is its own unit group
..

so each index has it's own entire unit group. When running "call DestroyGroup(udg_Group[0])", other groups won't be destroyed.

Also, clearing and destroying a group isn't quite the same.
"destroying" a group means the group doesn't exist anymore to work with at all.
"clearing" does only mean to remove all units from group. Technically, the group still exists and you can work with it, like adding new units, or so. It has just been emptied.

So, say if I had an MUI spell that uses dynamic indexing then, would I have to still run the custom script, since I'm going to reference it to a new variable? Or should I just remove all the units from the specific unit group?

Yes. You need to destroy the group to avoid leaks.

Okay cool, thank you both for the help!
