  • Field Details

    • lifecycle

      public Signal<Platform.Lifecycle> lifecycle
      A signal emitted with lifecycle events.

    • frame

      public Signal<Platform> frame
      This signal will be emitted at the start of every frame after the platform is started. Games should connect to it to drive their main loop.

    • errors

      public Signal<Platform.Error> errors
      Any errors reported via reportError(java.lang.String, java.lang.Throwable) will be emitted to this signal in addition to being logged. Games can connect to this signal if they wish to capture and record platform errors.

  • Method Details

    • time

      public abstract double time()
