== '''Reference''' ==
A lot of times, Util.longForName is referenced in the packets following:
public static long longForName(String arg0) {
String s = "";
for (int i = 0; i < arg0.length(); i++) {
char c = arg0.charAt(i);
if (c >= 'a' && c <= 'z')
s = s + c;
else if (c >= 'A' && c <= 'Z')
s = s + (char) ((c + 97) - 65);
else if (c >= '0' && c <= '9')
s = s + c;
else
s = s + ' ';
}
s = s.trim();
if (s.length() > 12)
s = s.substring(0, 12);
long l = 0L;
for (int j = 0; j < s.length(); j++) {
char c1 = s.charAt(j);
l *= 37L;
if (c1 >= 'a' && c1 <= 'z')
l += (1 + c1) - 97;
else if (c1 >= '0' && c1 <= '9')
l += (27 + c1) - 48;
}
return l;
}
In the 135 client, messages that are to be drawn on the login screen are stored in an array. This makes it a bit tedious to understand what messages are being drawn. Here is the message table:
static {
messageTable = new String[50];
messageTable[0] = "You must enter both a username";
messageTable[1] = "and a password - Please try again";
messageTable[2] = "Connection lost! Please wait...";
messageTable[3] = "Attempting to re-establish";
messageTable[4] = "That username is already in use.";
messageTable[5] = "Wait 60 seconds then retry";
messageTable[6] = "Please wait...";
messageTable[7] = "Connecting to server";
messageTable[8] = "Sorry! The server is currently full.";
messageTable[9] = "Please try again later";
messageTable[10] = "Invalid username or password.";
messageTable[11] = "Try again, or create a new account";
messageTable[12] = "Sorry! Unable to connect to server.";
messageTable[13] = "Check your internet settings";
messageTable[14] = "Username already taken.";
messageTable[15] = "Please choose another username";
messageTable[16] = "The client has been updated.";
messageTable[17] = "Please reload this page";
messageTable[18] = "You may only use 1 character at once.";
messageTable[19] = "Your ip-address is already in use";
messageTable[20] = "Login attempts exceeded!";
messageTable[21] = "Please try again in 5 minutes";
messageTable[22] = "Account has been temporarily disabled";
messageTable[23] = "for cheating or abuse";
messageTable[24] = "Account has been permanently disabled";
messageTable[25] = "for cheating or abuse";
messageTable[26] = "You need a members account";
messageTable[27] = "to login to this server";
messageTable[28] = "Please login to a members server";
messageTable[29] = "to access member-only features";
