Something about dynamic arrays

Hello,
so here is the thing, i know what it does but i don't understand how it does it if someone can explain it would be much appreciated, Thanks!

PHP Code:


		
			
new Array:GlobalArray;

public plugin_init() {

    new string[][] =

    {

        "String 1",

        "String 2",

        "String 3",

        "String 4"

    }

    new Array:StringHolder = ArrayCreate(32, 1);

    for(new i=0; i < sizeof(string); i++)

        ArrayPushString(StringHolder, string[i]);

    // we pass an array :/

    ArrayPushCell(GlobalArray, StringHolder);



    arraytest()

}

public plugin_precache() GlobalArray =  ArrayCreate(1, 1);

arraytest(){

    new  Array:AnotherArray;AnotherArray = ArrayGetCell(GlobalArray, 0);

    if(AnotherArray != Invalid_Array){

        new szString[32];

        for(new i = 0; i < ArraySize(AnotherArray); i++){

            ArrayGetString(AnotherArray, i, szString, charsmax(szString));

            server_print(szString);

        }

    }

}

Re: Something about dynamic arrays

Basic 2D arrays have a set size that cannot change, while dynamic arrays can adjust their size during runtime. Basic 2D arrays are best when you know the size beforehand and it won't change. Dynamic arrays are more flexible for changing sizes as needed.

Re: Something about dynamic arrays

Its not that thing i was talking about these lines

PHP Code:


		
			
ArrayPushCell(GlobalArray, StringHolder);
new Array:AnotherArray;AnotherArray = ArrayGetCell(GlobalArray, 0);
ArrayGetString(AnotherArray, i, szString, charsmax(szString));

Re: Something about dynamic arrays

I've read the tutorial long time ago and i know how to make dynamic arrays and use them, the thing that is confusing me when i push an dyn array that has strings into an dyn array ( 1 cell ) what happens,
and when i want to know the strings i put into that dyn array
i use this

PHP Code:


		
			
new Array:AnotherArray;AnotherArray = ArrayGetCell(GlobalArray, 0);

Srrry i'm not good with explaining
usage example ?
for example i created skins menu with ini file and there is 6 type each skin has 1...5 skins
[SKIN 1]
Skins = myskin1, ....ect
[SKIN 2]...
when u select u get random skins from the total skins.
what i don't really understand is that how that works cause i know how to do it i've seen the way in zp50_zombie_class system

Please do not delete your posts. Also, if you figure out the solution, post it so that others can benefit from it in the future. It is selfish to come to an open source community, ask questions and then delete the topic or not post the solution.

Re: Something about dynamic arrays

I suspect that the important thing to know about dynamic arrays is that the array handle is just a reference to the actually data and it can be stored like you would do with any other variable. This is why, you can store many of these array handles into a dynamic array making a pseudo-2D dynamic array.
