Unique Handles

[MasterDragons]

This is going to be difficult to explain, I will however, try my best.

I would like to note that I want a yes or no answer (Unless asking me to elaborate). If I am correct with my suspicions and it works, then I wish to do it my way, irregardless of other, perhaps even better, ways.

In a system I am making, I needed a fake handle to give to a fake item. (An Item that doesn't actually exist in the map) To do this I created an item, saved its handle and then removed it, in hopes of getting a unique unused Handle/Integer.

What I'm asking is:
If Im removing the item, will that handle eventually be recycled and reused later, therefore eliminating its unique-ness and making an overlap?

Thank you for your time,
~MD~

Yes, it will be recycled.

Damn, So If I want it to stay unique I need to leave a little are on the map with a bunch of the fake Items in it?

Yes. Otherwise that index will be "freed" and able to be used by some other handle that you create in the future. If you just want a unique integer, then you can always just choose a ridiculously high number or a number less than 1048576 and greater than 99. (as far as I know, no handles will be assigned any number between those two numbers)

Lightnings start from 1 counting upwards. Weather effects start from 0 counting upwards. Images start from 0 counting upwards. Basically, nearly any local handle does it (and constants). 1048576 = 2^20. Additionally, object editor ids are usually greater/equal 'A000' = 65*256^3+48*(256^2+256+1) = 1093677104. You can use another table or store in negative area. To gain unique ids, you would make a counter and the released ones get thrown onto a stack that you check first for free elements.

Thank you very much for your input guys. (Sorry for the late reply).
This will be very helpful for me.

I'm not sure who to rep. Can't add rep for all of you. ಠ_ಠ

Edit: oh, maybe I can. Well okay then.

If you don't null it, it won't get recycled . If you store the item handles into the hashtable and remove them, those ids will never be recycled as that could possibly cause handle stack corruption if they were (if they are recycled, blizzard is more stupid than I thought possible, lol).

I dont think you need to make so many fake items or even make one just to
recall a 'thing', coz getting a handleId in hash afterall are integers...

//these are already unique instances...
call SaveItemHandle(HT,456789,0,it)
call SaveReal(HT,456789,1,3.0)
call SaveReal(HT,456789,2,1.5)
call SaveUnitHandle(HT,456789,3,1.5)

Once again, sorry for the late reply. I wasn't expecting more conversation on the topic.

Nestharus' comment I vaguely understood, are you saying that the way I was trying to do it would work?

mckill2009, you left me confused. I'm afraid I do not know or understand jass.
-P.s: you should put a space between Dungeon Assault and For Horror in your sig. lol, That got me very confused.
