[MAX_PLAYERS] or not? - jack3 - 27.12.2011

I ask myself everytime i call a new variable what i have to use.

When do I have to use something like this:

pawn Код:

new Variable[MAX_PLAYERS];

or when I should use:

pawn Код:

new Variable;

It would be helpful if someone could explain that to me. :)

PS.: Sorry if a thread like this exists, but i didnt find it.

When you use MAX_PLAYERS you use variable as Variable[playerid], and is for a player, and if you dosent it is global variable...

if you want to save something thats related to each player individually then use [MAX_PLAYERS].
eg: when u wanna save each players money
Money[playerid] = GetPlayerMoney <== his money will be saved to his playerid slot of Money var

if you want to save something thats common for all like max player count, use new variable;

Im a troll in explaining -.- but i know how to use them

If you want the variable to be for a special purpose for example if you want it to be used by the server or by only one client then you go with

pawn Код:

new Variable;

If you want it to be used by every player or some other purposes for example using it for more than one purpose you go with

pawn Код:

new Var[MAX_PLAYERS]; // or
new Var[size];

I know I can't explain good.

Correct, I'll expand on it though as your description is slightly vague.

Declaring a variable such as:

pawn Код:

new Var;

is simple a single variable. You can only store a single piece of data in this variable (without messing about with binary and stuff).

Declaring a variable as:

pawn Код:

new Var[MAX_PLAYERS];

is called an array. An array can store multiple pieces of data related in 'slots' relative to the array itself. It's a little like doing:

pawn Код:

new Var1;
new Var2;
new Var3;
new Var4;
new Var5;
//etc...

(but, it uses slightly less memory if I remember correctly).
You can access (and set) data from/to an array by knowing the 'slot'. This could be stored in a variable or otherwise. Example:

pawn Код:

Var[playerid] = 1; //Where playerid is declared as an integer.
//Make Var[playerid] become 1.

pawn Код:

Var[0] = 0;
//Make the slot 0 of var equal to 0.

pawn Код:

for(new i; i < sizeof(Var); i++) //In this example, "sizeof(Var)" gets the array size.
{
    Var[i] = 100;
}
//This loop will make all the slots in the array called "Var" equal 100.

I hope you can understand better now.
