SetPlayerVirtualWorld

Parameters:

(playerid,worldid)

playerid

The ID of the player you want to set the virtual world of.

worldid

The virtual world ID to put the player in.

This function does not return a specific value.

Note: When a player spawns, their virtual world is automatically set to the default, which is 0.

if (strcmp(cmdtext, "/world3", true) == 0)
{
    SetPlayerVirtualWorld(playerid, 3);
    return 1;
}
