All Implemented Interfaces:

IObject, IPlayer, IPlayerControl

Direct Known Subclasses:

GoalKeeper

public abstract class Player

extends java.lang.Object

implements IPlayer, IPlayerControl

Every player in your team should extend this class!

It implements the IPlayer and IPlayerControl interfaces to give you full control and information of the player. Additionally it has some methods you must define to give information about your player, and some convenience methods for easier control.

There are seven abstract methods that must be implemented. Most important is the step method that controls your player.

• getName, getNumber, and isLeftHanded are used to give the game basic information about the player. The game will only call these once, upon startup.
• init is called after your player intelligence has been bound to an actual player. Here you can do initialisations which cannot be done in the constructor, such as setAimOnStick.
• Either faceOff or penaltyShot is called to notify you when the game is resumed after having been stopped for some reason. (Note that during penalty shots, only one of your players will be active!)
• step is by far the most important method of them all! This is where you control your player.
