DracoBlue has explained much things about how to keep score&money but as I understand, still many beginner people cannot exactly understand what he explains. That is why I have just wanted to share my filterscript I use on my server to save scores and money.

Here is the source code of my filterscript, actually you don't get any error or warning but if you get any of it, or if you don't know how to compile a PWN file, can download either PWN and AMX file though:

Here's the source code:

Code:

// Register / Login Filterscript //

#include <a_samp>
#include <dudb>
#include <dutils>
#define dcmd(%1,%2,%3) if ((strcmp((%3)[1], #%1, true, (%2)) == 0) && ((((%3)[(%2) + 1] == 0) && (dcmd_%1(playerid, "")))||(((%3)[(%2) + 1] == 32) && (dcmd_%1(playerid, (%3)[(%2) + 2]))))) return 1

//Colors//
#define COLOR_SYSTEM 0xEFEFF7AA
#define green 0x33FF33AA
#define blue 0x00FFFFAA
