Constructor Detail

TargetGame

public TargetGame(java.lang.String email,
                  com.google.android.gms.maps.GoogleMap map,
                  com.neovisionaries.ws.client.WebSocket webSocket,
                  com.google.gson.JsonObject fullState,
                  android.content.Context context)

Creates a game in target mode.

Loads the existing game state from the JSON provided by the server into instance variables and populates the map accordingly.

Parameters:

email - the player's email

map - the Google Maps control to render to

webSocket - the websocket to send updates to

fullState - the "full" update from the server

context - the Android UI context

Method Detail

getTeamScore

public int getTeamScore(int teamId)

Gets a team's score in this target mode game.

Specified by:

getTeamScore in class Game

Parameters:

teamId - the team ID

Returns:

the number of targets owned by the team

handleMessage

public boolean handleMessage(com.google.gson.JsonObject message)

Processes an update from the server.

Since playerTargetVisit events are specific to target mode games, this method handles those. All other events are delegated to the superclass.

Overrides:

handleMessage in class Game

Parameters:

message - JSON from the server (the "type" property indicates the update type)

Returns:

whether the message type was recognized

locationUpdated

public void locationUpdated(com.google.android.gms.maps.model.LatLng location)

Called when the user's location changes.

Target mode games detect whether the player is within the game's proximity threshold of a target. Capture is possible if the target is unclaimed and the new line segment from the player's previously captured target (if any) does not intersect any other line segment. If a target is captured, this method sends a targetVisit update to the server.

Overrides:

locationUpdated in class Game

Parameters:

location - the player's most recently known location
