Then do "-5". "--" = Decrease by 1.

Ex:

PHP код:



amount-5; // This will decrease "amount" by 5.

PHP код:



amount--; //This will decrease "amount" by 1. It's the same as doing "amount-1;".

Still can't figure it out xD

This is how it goes :

PlayerInfo[playerid][MyVariable] -20;

- I Want it to subtract 20 of the amount he has.

If you want to add or subtract a value, you need to use it like this:

Код:

var -= 20; // minus 20
var += 34; // plus 34

You can only use -- and ++ for quickly subtracting or adding 1

Код:

PlayerInfo[playerid][MyVariable] -= 20;

equal

Код:

PlayerInfo[playerid][MyVariable] = PlayerInfo[playerid][MyVariable] - 20;
