GUI unit group questions

[IsaacNewbton]

Wondering if there is any great deal of difference between clearing unit groups in different ways in GUI

1) At the end of each branch of a "pick all units in group and do actions" loop, do "remove picked unit from group"

2) After the "pick all units" block, do "clear group"

3) Custom Script: set group = null


Additionally, is it always good to do a "Unit group is empty" check before running a "pick every unit in unit group" loop?

Usually groups in GUI should be destroyed after use, if you don't need the group anymore.

• Custom script: call DestroyGroup(udg_variableName)

Global variables need not to be nulled.

Usually it is not necessary to check if a group is empty or not.

does it matter if a group is empty before you destroy it? I might not have to remove units from a temporary group at all then

You don't have to remove units from a group before you destroy it. You can destroy an empty group.

A Question: Will destroying a unit group in a loop trigger of an ability, Say one that holds caster units will this effect units that would need to be in the group still? I don't currently use call destroygroup but if its better I will make the changes.

dont destroy a group unless you plan to re-assign it by using "set unit group ="

a destroyed unit group cannot be referenced by its global variable until that variable is set to a new group
