== '''Reference''' ==
A lot of times, Util.longForName is referenced in the packets following:
Player usernames are encoded and decoded as a long with the following methods:
<pre>
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')
