The meaning of substracting 0x100000 of integers

[Embrace_It]

Hi all,

In many systems that I have been trying to understand, I have seen something like this:

    GetHandleId(...) -0x100000 // Keeping with the new native...

I am guessing that the 0x100000 is a number in binary code.

My question: What is the purpose of this?

GetHandleId will return handles's id.
0x100000 is the starting of handle id.

This formula helps to store in globals with array, since array only has 8191 slots.

any numbers prefixed with "0x" are Hexadecimal numbers ... not binary numbers.

With the new natives this shouldnt be needed anymore anyway, since hashtables arent limited as arrays...

But they are slower?

Probably. But they are still much faster than Gamecache.

Confirmed?

I'm going to take Karune's word for true on this matter.

However unlike the GameCache which uses strings for keys, the hashtable uses integers. Additionally, storing and retrieving data in hashtables are much faster and safer than storing data in the GameCache.

Linky if you wish.

Ok, I think I understand. It is for starting at the beginning of an array.

any numbers prefixed with "0x" are Hexadecimal numbers ... not binary numbers.

Thanks for pointing that out

benchmark are coming soon, as Mindworks finishes the new StopWatch Natives (i am hoping he will ..some day)
