//add to your command
        new Float:X, Float:Y, Float:Z;
        GetPlayerPos(playerid,X, Y, Z)


        for (new i=0; i < MAX_PLAYERS; i++)
        {
            if(IsPlayerInSphere(i,X, Y, Z, radius))
            {
                SetPlayerSkin(i,skin);
            }
        }

i hope that this will help ^^'
