System Unit Indexer

Unit Indexer​

Version 1.0.1​

See attached SC2Lib file.
Allows you to get a unique integer for a unit, and get the unit back from that integer.

Good for attaching using arrays.

I've been wondering, how does the indexing (Node/Nodestack) you use work?

I'm hooking up all these arrays in this hit detection I'm making and I have a feeling I can do it all a lot easier.

Copy/paste the layer #1 from one of my systems and just use alloc/dealloc... it's like creating/destroying an empty struct in vJass. They're just unique integers for their set.

Basically, I'm reconstructing vJass concepts in SC2 GUI.

Of course, now I've indexed "timers" and units, and created Event, so there's probably not too much more you'd need...

I know I could just copypaste the allocation/deallocation and just add the required fields to my objects.

I see it indexes by defining which was the previous object and which is the next object. (And linking the last up to the first)

But when I look at it I keep wondering:

Where is IndexStack[2048] for? You're only using IndexStack[0], and then you only set it to "index" in DeAllocIndex and return it in IndexStack, so why the 2048 extra array fields?

My bad. Something was critically wrong. Seems the copy/paste in the editor is not always reliable.

Download new version from first post.

Just taking:
IndexMax = 0 <Integer>
IndexStack = 0 <Integer[2048]>
IndexStackMax = 0 <Integer>
AllocIndex
DeallocIndex

should do the trick.
You may not need 2048 possible indexes, depending on what you're indexing. The size of that array is the number of indexes that can be freed at once.

Edit: Actually, this whole thing can be very slightly optimised, by removing the if from inside the allocate, but I think it's lame and don't feel like implementing that. In theory, you could allocate all the indexes at map init time into the stack array. *Shrugs*
