use:

pawn Код:

new PlayerVirtualWorld = random(128);
SetPlayerVirtualWorld(playerid, PlayerVirtualWorld);

should work

or if you want to have a special virtual world for EACH player, so NOone will be in the same, i recommend you to use:

pawn Код:

SetPlayerVirtualWorld(playerid, playerid); // this will set every players interior to the id he has, so everyone will have a different one
