FXGameComposer

FXGameComposer is a game authoring tool and also a game runtime environment, targeting at JavaFX2 or HTML5 capable devices.

GameComposer

GameComposer is the authoring tool, the IDE. It is a JavaFX2 application. Using this tool, games can be designed and tested. Finally, they can be exported to a target runtime, e.g. HTML5.

GameEngine

GameEngine is the cross-platform game engine.

Core concepts and components of the game engine are:

Concept / component	Description
Game	A Game is the top level container. Each Game is split into several GameScenes.
GameScene	A Scene is like a level of a game. A Scene has a collection of GameObjects, Assets and Events.
GameSystem	A GameSystem defines a subsystem of the game engine. There are GameSystems for physics, sounds and other stuff
GameView	A GameView is the presentation of a GameScene to some kind of consumer. This can be a screen renderer or even a remote consumer.
GameObject	A GameObject is a template for visible objects. The behavior of a GameObject is defined by GameComponentTemplates
BehaviorTemplate	A BehaviorTemplate defines some kind of behavior, e.g. if it is static, a sprite or driven by physics.
GameObjectInstance	A GameObjectInstance is an instance of a GameObject. It inherits the defined BehaviorTemplates by copying them into a Behavior
Behavior	A Behavior is the behavior status for a BehaviorTemplate and a GameObjectInstance.
Event	An Event can be triggered by a consumer by sending it via the GameView to the engine. An Event can also be triggered or consumed by a GameComponent or GameSystem.
EventSheet	An EventSheet is the rule engine. Each rule has a condition and some actions.
GameLoop	The GameLoop drives the engine by calling the GameSystems, rendering the GameView and dispatching events.
GameProcess	A GameProcess is something that takes multiple GameLoop cycles to complete, for instance playing background music or playing an animation.

Current travis-ci build status:

GameEngine-FXRenderer

This is the game presentation logic by implementing a GameView using JavaFX 2. This also includes a Soundsystem implementation based on Java Sound API.

GameEngine-GWTRenderer

This is the game presentation logic using GWT and HTML5(JavaScript) by implementing a GameView. This also includes a SoundSystem implementation based on HTML5 Media API. Currently the HTML5 renderer tries to use WebGL. If WebGL is not available, it will fallback to the HTML5 Canvas API.

GameEngine-AndroidRenderer

This is the game presentation logic using the Android Java SDK. This also includes a SoundSystem implementation for Android devices. We use an Android SurfaceView for rendering. Future versions will include OpenGL ES support.

GameEngine-DragomeRenderer

This is the game presentation logic using the Dragome Java-to-JavaScript Transpiler Framework. It will render the game view using the HTML5 Canvas API.

GameEngine-TeaVMRenderer

This is the game presentation logic using the TeaVM Java-to-JavaScript Transpiler Framework. It will render the game view using the HTML5 Canvas API.

GameEngine-Networking

Networking support is implemented as a RemoteGameView. Local events are sent between game instances to sync the distributed game models.

Networking is implemented in a very early beta state only by the TeaVM Renderer. Events are sent to a Firebase instance, which then syncs the events back to other browsers bound to the same Firebase instance. Take a look at the Networking example to see it in action. In this case, Firebase acts as a non-authorative game server. The game models and simulation is still run in the local browser. Only the game state is synchronized using events.
