GroupInRange is primarily a GUI tool which automates the following:
The attached demo map has a custom Divine Shield which orders all surrounding units to "move to" the Paladin's position, but uses the automatic filtering to weed out the Meat Wagon and the Gryphon Rider.
- Picks all units in range of a point and adds them to a leak-proof unit group
- The units in range of that point are scanned for their collision sizes, just like in the classic vJass GroupUtils
- The units are also checked for criteria which most spells and attacks want to screen out by default:
- is a unit dead, mechanical, structure, magic immune or flying?
- is a unit an enemy of another particular unit?
- In addition to these, it provides some easy mechanisms to either exclude another unit group from being considered by the list, or even specifying a maximum number of units who can be added (with any excess units thrown out at random).

Lua:

GroupInRange v1.2 by Bribe
What it does:
1) Collects all units in range of a point and adds them to a leakless group (GroupInRange_units)
2) Automate exclusion of common unit classifications (e.g. spell immune/allies)
3) Allows custom filters to be built in real-time.
4) Provides GroupInRange to Lua users, which allows persistent filters without having to rebuild them from scratch each time.
Why it can benefit:
1) You no longer have to think about whether your group will leak, as this does not.
2) Shorter triggers and easier configuration of filters.
How it works:
1) Using Action, it allows you to specify custom filter definitions within the Actions block of GroupInRange_filter.
2) Uses the same mechanics that were introduced in GUI Spell System, but built them universally for the sake of modularity (e.g. can be used with damage events).

GUI Variables:
player group udg_GroupInRange_filter
--MANDATORY variables to set:
real udg_GroupInRange_radius
point udg_GroupInRange_point
optional boolean filters default:
udg_GroupInRange_allow_self false
udg_GroupInRange_allow_allies false
udg_GroupInRange_allow_enemies true > self, allies and enmies can only be determined if a source unit is specified.
udg_GroupInRange_allow_heroes true
udg_GroupInRange_allow_nonHeroes true > By default, all heroes and non-heroes are included.
udg_GroupInRange_allow_living true
udg_GroupInRange_allow_dead false > By default, only living units are included.
udg_GroupInRange_allow_flying false
udg_GroupInRange_allow_magicImmune false
udg_GroupInRange_allow_mechanical false
udg_GroupInRange_allow_structures false > By default, these are excluded.
--Optional setonly variables for extra filtering:
integer udg_GroupInRange_max > Do not pick any more units than this number (excludes units at random).
unit udg_GroupInRange_source > if specified, enables filtering for enemies and allies.
unit group udg_GroupInRange_exclude > Do not add any units from this group.
--Readonly
unit group udg_GroupInRange_units > The group of units who passed the filters.
intger udg_GroupInRange_count > Number of units in that group
If you want to save the units for a longer duration, assign a group variable to (Last created unit group) as this will create a copy for you to use.
