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 game state from the JSON provided by the server and populates the map accordingly.

Parameters:

email - the user'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.

You need to implement this function.

Specified by:

getTeamScore in class Game

Parameters:

teamId - the team ID (same kind of value as the TeamID constants)

Returns:

the number of targets owned by the team

handleMessage

public boolean handleMessage(com.google.gson.JsonObject message,
                             java.lang.String type)

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.

Some of this function is written for you, but there is a little piece for you to fill in.

Overrides:

handleMessage in class Game

Parameters:

message - JSON from the server

type - the update type

Returns:

whether the message type was recognized and handled

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, a targetVisit update is sent to the server.

You need to implement this function, though much of the logic can be organized into the tryClaimTarget helper function below.

Specified by:

locationUpdated in class Game

Parameters:

location - a location FusedLocationProviderClient is reasonably confident about
