Unit Group or Unit Index

[Pinzu]

Say we have to loop through 100, 500 or even 1000 units when we are looking for units that are out of mana, is there a point in indexing them instead of using

set u = FirstOfGroup(g) 
// or
set u = u_Index[i]

?

I would say using unitgroups is the best way because it's dynamic.

Because if you got
u[1-999]

and then remove u[55] there'll be an empty space in the array that wont be used unless you re-arrange the array. Unitgroups does this automatically so it should save you some time.

Using an array is faster though. Gaps are not a problem.

For units that are out of mana...
none.
mana regeneration doest stop.

i wonder why you need all units that are out of mana
it might be better to add units to a group of units which are categorized as out of mana

Its a starvation detection.

I didn't say "there are no solutions" I said that it would save him some effort.

Yes something like that. I mean if an array is faster and the only difference would be instead of removing the unit from the group you would have to decrease the index size. The drawback would be that every time a unit dies/enters map you would have to add them which might be significant. So why bother, then again, they are already being indexed/deindexed at some point, might aswell make them add to another index instead. And then again.... The filter would have to load a hashvalue to find out if the unit is of a certain type... ;d

For units that are out of mana...
none.

All units have negative mana regeneration.
