[Snippet] Unit List

What advantages does this have over a normal unit group?

 

[Nestharus]

It's nothing like a unit group... lol

It adds each indexed unit to a list for iteration


->A snippet that puts all units in the map into a list for iteration.

Then what is it used for? xD It seems just like a big group of units to me, but the only difference is that has order. (of ID's) And that it is ordered in a list. In big maps, this seems like it may grow concerns for the op-limit.

Unless I am still not following it, in which case I need an example to understand its purpose more. =P

 

[Nestharus]

oh, I made it for iterating through all indexed units in the map. When I made UnitRegen or w/e, I needed a way to iterate (actually, I made 2 scripts that needed iteration, so I abstracted the code to a separate resource).

I could add a group as well if you like. You might hit op limit if you loop over 6000 units 3x, lol, so yea, a group could be useful ^)^.

You should throw this into UnitIndexer because UnitIndexer already has a list for indexed units (the one that you appear to just "throw away" right after initialization).

Why is there a group for all units?

Multiple iterations

I could make this an extension I guess, but that'd get so sloppy ;\. Oh well, give me a bit and I'll make it an extension library.

edit
Nah, the UnitIndexer list is optimized specifically for the adding to the list before game starts. Actually, nvm, give me a bit.

Such a simple thing might as well be merged with UnitIndexer altogether. It's a good snippet. A simple one, but definitely good. Approved.

Going through iteration is a lot slower than using unit groups

 

[Bribe]

Dirac, nice of you to share your thoughts in your first post, but
you have absolutely no evidence.

 

[Magtheridon96]

Using unit groups would be worse lol

ForGroup does the same thing that iteration does, but it's slower cause it has to create a new thread for each unit, run it, start the next thread, run it, etc..
Iteration is the same, but it doesn't have as much overhead as putting the units in a group and calling ForGroup.

Iteration = ForGroup() - (Overhead of function call + 1 thread per unit)

I have lots of evidence:

Ran lots of tests comparing unit retrieval from arrays and from GetFilterUnit()

Seems that 200 groups with 5 units in it crashes arrays, but only mildly slow down natives

 

[Nestharus]

FirstOfGroup is not the same as ForGroup.


Link to your benchmark that proves ForGroup is faster than looping through an array or linked list.

 

[Dirac]

I take back what i said about unit groups.

I got my info from a bugged benchmark.

EDIT: both are very fast, ForGroup or loop iteration.
