This sum score:

pawn Код:

PlayerInfo[playerid][score]++;

What but how do I add a number ? Example +10

What would be as well ?

pawn Код:

PlayerInfo[playerid][score]+10;

What you wanna to do plz explain it briefly

PHP код:

//Add 10 to the player's score.
PlayerInfo[playerid][score] += 10; 


which is the same as

PHP код:

//Add 10 to the player's score.
PlayerInfo[playerid][score] = (PlayerInfo[playerid][score] + 10); 


So, a += 1 or a = (a + 1) is the same as a++!

The difference here is that a + b is an arithmetic expression and not a statement. a + b will yield the result of a + b, but a += b will assign the value of a + b to a. This means "+=" just adds the value to the variable on the left hand side and stores it.

An example of it in use:

PHP код:

//Declare a and b
new a = 5;
new b = 3;
//Add 3 to 5, put in a
a += b;
//This would print out 8.
printf("%d", a); 


Another thing to note about this operator is that like most other operators, it can be "chained" in sequence, which comes in handy sometimes:

PHP код:

//Declare a, b and c.
new a = 5,
    b = 3,
    c = 6;
//Add C to B, and add B to A
a += b += c;
//Print out result. We should get 14 (5 + (6 + 3))
printf("%d", a); 


which is the same as

PHP код:

//Declare a, b and c.
new a = 5,
    b = 3,
    c = 6;
//Set a to (a + b + c)
a = (a + b + c);
//Print out a. We should get 14 (5 + 3 + 6).
printf("%d", a);
