dtEntity is a game and simulation engine using OpenSceneGraph for visualization.

Features:

• Pure component system - functionality is shared by composition, not by inheritance. No data or functionality in game object, game object is an aggregation of components.
• Entity system approach to storing components - components are stored by type, not by game object
• Fully scriptable with Google V8 JavaScript
• Integrates libRocket GUI and CEGUI
• Publish-Subscribe message system
• Many existing components: Mesh, animation, text label, camera, transform, sky box, ground clamper...
• Plugin system for loading additional component libraries
• XML map format, maps can be independently loaded and unloaded at runtime
• Qt based map editor
• A Qt property editor, property edit masks are configurable on a per-property basis in an xml file (for example: Vec4 Property 'color' in component of type TextureLabel should be edited with a color picker)
• Hierarchical composition of entities is possible - use attachment points to define where in scene graph an entity shows up. Example: Sky box entity has a component "LayerAttachPoint" that other entities can choose to attach to.
• Can be compiled to use Delta3D actors. This way, delta3d features like Cal3d animation, clouds rendering etc can be used.
• Debug draw manager for quickly displaying debug geometry like lines, points, triangles
• Prototypical PhysX bindings

This is a screencast of messing around with dtEntity Qt editor. Dropping some entities into the scene, using tools to transform them, using property editor to modify properties.
