Method Detail

values

public static Player.Stance[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Player.Stance c : Player.Stance.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Player.Stance valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

badStance

private void badStance()
                throws java.lang.IllegalStateException

Throws:

java.lang.IllegalStateException

badTransition

private void badTransition(Player.Stance newStance)
                    throws java.lang.IllegalStateException

Throws:

java.lang.IllegalStateException

getStanceFromTension

public Player.Stance getStanceFromTension(Tension tension)

Check whether tension has changed enough to merit a stance change. Do not simply check for crossing tension thresholds, add in Tension.DELTA to provide a bit of hysteresis to dampen ringing.

Parameters:

tension - The Tension to check.

Returns:

The Stance appropriate to the tension level.

getTensionModifier

public int getTensionModifier(Player.Stance newStance)
                       throws java.lang.IllegalStateException

A stance change is about to happen. Get the appropriate tension modifier.

Parameters:

newStance - The new Stance.

Returns:

A modifier to the current tension.

Throws:

java.lang.IllegalStateException
