what is better

[kaboo]

2 unit group variables - team1 and team2

1 unit group variable with array[2] - team[1] and team[2]

whats your opinion and why?

i prefer the second code
bcause it only use 1 variable instead two or more.
plus it is easy to modify or use it later for loop trigger.

Well, both basically the same just that I think they both have their advantages.

The array is more versatile in loops and such ( As The-Shadows said ) and can sometimes be easier to handle...

The "Two-variables" version is better simply because it's much easier to divide, like if you'd create a spell and it would do something with allies in a group, and something else for the enemies in it.
Then you could use two different unit-group variables, and name them something like "Caster_Allies" and "Caster_Enemies" so you can easily keep track of which one of the two to use in different occasions

Those are just my oppinions
