Constructor Detail

VolleyballCourt

public VolleyballCourt(Zone z)
                throws GameLogicException,

Parameters:

z - zone

Throws:

GameLogicException - WRITEME

NotFoundException - WRITEME

Method Detail

acceptGameAction

public void acceptGameAction(AbstractUser u,
                             org.json.JSONObject action)

Description copied from interface: RoomListener

Broadcast message of a game action taking place

Parameters:

u - the sender

action - The game action. The verb is in action.getString("action").

See Also:

RoomListener.acceptGameAction(org.starhope.appius.user.AbstractUser, org.json.JSONObject)

acceptOutOfBandMessage

public void acceptOutOfBandMessage(AbstractUser sender,
                                   Room room,
                                   org.json.JSONObject body)

Description copied from interface: RoomListener

Accept an out-of-band communications packet that was broadcast to a room in which this Listener is listening.

Parameters:

sender - The sender of the OOB message

room - The room in which the OOB message is being broadcast

body - A JSON object containing the OOB message. The contents of this message are not constrained.

See Also:

RoomListener.acceptOutOfBandMessage(org.starhope.appius.user.AbstractUser, org.starhope.appius.game.Room, org.json.JSONObject)

acceptPublicMessage

public void acceptPublicMessage(AbstractUser from,
                                String message)

Description copied from interface: RoomListener

Accept a public chat message. This prototype does not specify the room, on the (potentially invalid) assumption that the room listener doesn't care from which room the speech was made.

Parameters:

from - The speaker

message - The spoken text or /emote

See Also:

RoomListener.acceptPublicMessage(org.starhope.appius.user.AbstractUser, java.lang.String)

acceptUserAction

public void acceptUserAction(Room r,
                             AbstractUser u)

Description copied from interface: RoomListener

User actions (go/do actions) propagate through this channel.

Parameters:

r - the room in which the user is taking an action

u - the user taking an action

See Also:

RoomListener.acceptUserAction(org.starhope.appius.game.Room, org.starhope.appius.user.AbstractUser)

ballLocation

private org.starhope.appius.geometry.Coord2D ballLocation()

Gets where the clients think the ball is, taking into account the Z offset (2D projection of 3D coördinates)

Returns:

where the clients think the ball is, taking into account the Z offset

destroySelf

public void destroySelf()

Cleanup routine to make sure we get garbage collected properly

Overrides:

destroySelf in class GameEvent

dropBall

void dropBall(org.starhope.appius.geometry.Coord2D coord2d,
              double height)

Drops the ball from the given height at the specified coordinates

Parameters:

coord2d - Drop location

height - Drop height

getGameEventPrefix

public String getGameEventPrefix()

Description copied from class: GameEvent

Get the prefix to be applied to event types for this game

Specified by:

getGameEventPrefix in class GameEvent

Returns:

the string prefix used to find event types for this game

See Also:

GameEvent.getGameEventPrefix()

getName

public String getName()

Description copied from interface: HasName

Return a user-visible, unique name for this class. This name may not necessarily be globally unique, but must be unique across all objects of this class. For example, having both a User and a Zone named “Lightning” is acceptable, but there may not be two users with the same name.

Returns:

a user-visible string name for this instance

See Also:

HasName.getName()

tick

public void tick(long currentTime,
                 long deltaTime)
          throws UserDeadException

Description copied from interface: AcceptsMetronomeTicks

This method is called periodically from the metronome thread. To save computation, it receives both the current time since epoch in milliseconds at the start of the global tick propagation, and the delta time since the previous metronome tick.

Specified by:

tick in interface AcceptsMetronomeTicks

Overrides:

tick in class GameEvent

Parameters:

currentTime - Time since epoch at the start of the global metronome propagation, as per System.currentTimeMillis()

deltaTime - Delta-time in milliseconds since the prior global metronome tick

Throws:

UserDeadException - if a user has died during this tick

See Also:

GameEvent.tick(long, long)

updateBallLocation

private void updateBallLocation()

Updates the ball's location
