I think ****** once said:
"If you don't know the difference between 'new' and 'static', then don't use it"

Bullshit...

If he don't know the difference between "new" and "static" he ask. So, he did it.

The difference between "static" and "new" is, that the declaration of "static" can used also in filterscripts, includes and gamemodes at the same time.. The declaration of "new" can't used in filterscripts, includes and gamemodes at the same time.

There are more diffrences...

static saves the pointer of an variable in the stack/heap.

For example:

PHP код:



stock func()

{

    static a;

    printf("%d",++a);

}


//main()

func(); //It will print 1

func(); //It will print 2

And if you use for example:

PHP код:



//in the include

static x;


//You can use in the main mode

new x; //without problems

Oh ok, but 1 more question. I have an include called def.inc which has all of my arrays, enums, defines and other vars stored. If i create a connection handle for mysql in that include with static, it gives undefined symbol error, but if i create it with new, it works fine. Why is that?

Because of the scope of static.

Read my post...read the post in the wiki...

Static variables remember their old values, and can only be used in the script in which they're declared.

Because 'static' variables only exist within the script they are declared in. So if you put it in your include file, the variables will not work outside of that include file.
