[General] Two Questions on Unit Groups

[Adorm]

Hey Guys,
How do you create a Unit Group through a Custom Script/JASS? And also, is it possible to check if a Unit Group is Empty and if so how would both of these things be accomplished through Triggers? Thanks so much!
Cordially,
Adorm

This creates an empty group:

local group g = CreateGroup()

If you want to pick units in range of a point you can use:

call GroupEnumUnitsInRange(g,x,y,radius,null)

To check if group g is empty you can check:

if(FirstOfGroup(g)==null) then

endif

Is it possible to check if the group is empty through a normal GUI Function?

what do you mean?

Boolean Comparison - Unit Group - Unit Group is empty

• ((Last created unit group) is empty) Equal to True

Thank you so much!
