Change view distance based on server load

[Cogito]

The server admin should configure some settings so that the view distance will automatically change when the load on the server crosses some threshold.

Basic idea is to have a set of transitions defined, mapping the action to take when moving from one condition to another.

For example, a transition might define that when the number of players on the server goes from being less than 20 to more than or equal to 20, the view distance should be set to 7. Another transition could set the view distance to 10 when the player count drops below 10.

Transitions could include things like time since last transition as a condition, however that will be for improvements down the track.

This is not my code it is V10lator's code

public class PlayerManager
{

public PlayerManager(MinecraftServer minecraftserver, int i, int j)
{
    a = new ArrayList();
    b = new PlayerList();
    c = new ArrayList();
    if(j > 15)
        throw new IllegalArgumentException("Too big view radius!");
    if(j < 3)
    {
        throw new IllegalArgumentException("Too small view radius!");
    } else
    {
        f = j;
        server = minecraftserver;
        e = i;
        return;
    }
}
