  • Method Details

    • getListeners

      Seq<ApplicationListener> getListeners()
      Returns a list of all the application listeners used.

    • addListener

      default void addListener(ApplicationListener listener)
      Adds a new application listener.

    • removeListener

      default void removeListener(ApplicationListener listener)
      Removes an application listener.

    • defaultUpdate

      default void defaultUpdate()
      Call this before update() in each backend.

    • getType

      Application.ApplicationType getType()
      Returns:
      what Application.ApplicationType this application has, e.g. Android or Desktop

    • isDesktop

      @Deprecated default boolean isDesktop()
      Deprecated.

    • isHeadless

      @Deprecated default boolean isHeadless()
      Deprecated.

    • isAndroid

      @Deprecated default boolean isAndroid()
      Deprecated.

    • isIOS

      @Deprecated default boolean isIOS()
      Deprecated.

    • isMobile

      @Deprecated default boolean isMobile()
      Deprecated.

    • isWeb

      default boolean isWeb()

    • getVersion

      default int getVersion()
      Returns:
      the Android API level on Android, the major OS version on iOS (5, 6, 7, ..), or 0 on the desktop.

    • getFrameId

      default long getFrameId()
      Returns the id of the current frame. The general contract of this method is that the id is incremented only when the application is in the running state right before calling the ApplicationListener.update() method. Also, the id of the first frame is 0; the id of subsequent frames is guaranteed to take increasing values for 263-1 rendering cycles.
      Returns:
      the id of the current frame

    • getDeltaTime

      default float getDeltaTime()
      Returns:
      the time span between the current frame and the last frame in seconds. Might be smoothed over n frames.

    • getFramesPerSecond

      default int getFramesPerSecond()
      Returns:
      the average number of frames per second

    • getJavaHeap

      default long getJavaHeap()
      Returns:
      the Java heap memory use in bytes.

    • getMainThread

      @Nullable default Thread getMainThread()
      Returns:
      the main graphics thread, upon which all ApplicationListener methods are called. May return null if not initialized.

    • isOnMainThread

      default boolean isOnMainThread()
      Returns:
      whether the currently executing thread is the main thread. If the main thread is not initialized, returns true by default. This is used for error checking purposes.

    • getDnsServers

      default void getDnsServers(Seq<InetSocketAddress> out)

    • post

      void post(Runnable runnable)
      Posts a runnable on the main loop thread.

    • exit

      void exit()
      Schedule an exit from the application. On android, this will cause a call to pause() and dispose() some time in the future, it will not immediately finish your application.

    • dispose

      default void dispose()
      Disposes of core resources.
      Specified by:
      dispose in interface Disposable
