Hashtable vs Hashtables

[Skyflash]

Hello Hivers
I Got too confused about Creating a Hashtable and Working with it for all of my map`s spells or Creating Multiple Hashtables for example per Hero or per spell which method works better whats the advantage by using it?

Just take a look at hashtable tutorials.

You have a limit of 10(?) hashtables per map. You can't have one for each hero, Also it's not required. There are lots of keys for hashtables and it becomes better when we have 2 keys for it!

You are limited to 256 Hashtables per map.
Personally I'm not really sure how to use table, but I made my own way for using a hashtable with 3 keys.
This way 2 hashtables are enough for your whole map.
You can check this if you want.
In the last post there is an "alternative", where things aren't automated, but it's a lot lighter.

The higher value a hashtable use the slower it gets, so using one hashtable per spell/system is more efficient.

But due the 255 limit, one might have to rethink.

so using one hashtable per spell/system is more efficient.

Do you know the point where it reaches "There is enough uses of this Hashtable, let's make a new Hashtable" ?

I need to know this for large-scale uses of the Hashtable.

It would go to waste to use 1 Hashtable per spell, seriously, in a large-scale map RPG, or something (even AoS).

Personally I use 2 hashtables for my map + a hashtable for each system (which needs it).

Maybe around 200-500 handles, only then we need a new Hashtable (this is just a rough estimation tho).

That is very few, I think. A hashtable can store that without any problems.

I have around 5 or 6 hashtables in my map, though I think there is still at least 1 that can be removed in favour of an array using unit indexes.

Hashtables are fine to use only one for everything in your map or have 255 that all work cooperatively to store all the data you need.

I presonally think you shouldnt care that much.
But as long as you do not need a hashtable, you should use normal arrays.

There are a total of more than one trillion slots in hashtables so you can store more data than even your Hard Drive supports.
I am talking about 16 Zebibytes of data... (16,384 Exabytes or 16,777,216 Petabytes or 17,179,869,184 Terabytes)
That not even using handles but only primitive types.

If you only need one row of a hashtable, you can use Table instead.
But if you only need one row, you can probably do it without a hashtable.
