There have been better versions of anti drive by in 0.2 (it just needed some storage)
the only improvement is the new function SetPlayerArmedWeapon

Useful macros:

#define isEven(%1) \
        (!((%1)&(01)))

 
#define isPowerOfTwo(%1) \
        (!(%1)&(%1-1))

OnPlayerEnterVehicle-callback.

it´s not from me, but this is cool:

if(strcmp(cmd, "/haha", true) == 0)
 {
 new player;
 tmp = strtok(cmdtext, idx);
 if(!strlen(tmp))
 {
  SendClientMessage(playerid, COLOR_WHITE, "[USAGE]: /haha [playerid]");
 }
 
 player = ReturnUser(tmp);
 if (player == playerid)
 {
  SendClientMessage(player, COLOR_RED, "You can´t laugh at yourself!");
  return 1;
 }
 if(IsPlayerConnected(player))
 {
   if(player != INVALID_PLAYER_ID)
   {
   new string[128];
  GetPlayerName(playerid, sendername, sizeof(sendername));
  format(string, sizeof(string), "* %s laughs at you!", sendername);
  SendClientMessage(playerid,COLOR_RED,string);
  }
  }
		return 1;
		}

This is wrong, this will get the name of the player who used the command and it will send the message to him.
