• Script-side GameStates
  It is now truely possible to derive from the GameState class (through CGameState) in scripts. A bug in previous versions prevented this, but this bug has now been fixed.
• Script-side Components
  EntityComponent can be derived from script-side (through CEntityComponent), classes in script can now create components and register them with entities from script or engine side.
• Script-side Events
  The event system is now integrated into the script engine. Script-side classes can derive from IHasSlots and can register, connect and disconnect from slot events.
• Important Bug Fixes:
  • Construction of entity components with parent is now relatively safe. If you are not sure whether your component has a parent, check it after construction. If the component has no parent, destroy it as quickly as possible
  • AssetProcessors on windows were never loading assets unless the files were all lowercase, restrictions were irrlicht related but solved.
  • Minor bug fixes with script side things, Scolor fixes, asset groups on entities and much much more.

• Asset Management
  The biggest new feature is asset management. Assets are managed by the AssetManager class. This manager manages so-called asset groups, which represent a collection of assets (meshes, textures, etc). These assets are retrieved from a directory with the appropriate directory structure. In turn the found assets are processed by asset processors. And at the end of the road, the user can use these assets without having to deal with paths. Furthermore asset management makes it possible to reload all assets in realtime, with direct results on the current scene. Reloading assets is as simple as one function call.
• XML-based Entity files
  It is now possible to load data concerning entities and their components from XML-files. This means that you can now define a scene through XML-files.
• Local Event System
  As of version 0.2.0 a HasEvents class, which provides the base for a local event system, is available. The availability of local event systems makes the entire framework more performant. Currently the HasEvents class is used by entities and asset groups.
• Microsoft Visual C++ 2008 support
  Version 0.2.0 is the first release that officialy supports Microsoft Visual C++ 2008. This should make it easier to set up Sirrf-based projects accros multiple platforms.

See the change log for more information regarding the changes in Sirrf version 0.2.0.

This is not the end of Sirrf’s development, though. Sirrf’s development will continue and Sirrf will undoubtely become even better in the future. And you, as a Sirrf user, as a member of the Irrlicht community, can help us improve the framework. This can be done by contributing code to the project, but also by testing the framework. Either way, we hope that Sirrf will be of use.

But what can Sirrf do for you? In it’s current state Sirrf offers game logic, graphics, scripting and sound control. Some noticeable features are:

• Data Store
  The Data Store allows you to store primitive value types such as integers, floats and doubles in a type-independent format. These variables can be accessed from anywhere within the framework, from both native and interpreted code, through the DataStore and DataStack classes.
• Entity Management
  In Sirrf entities are component-oriented. The idea behind Component Oriented Entities is to make entities data-driven. In order to do this the functionalities are split in various individual components. As a result an entity is in fact nothing more than a collection of components. So, what an entity represents, is defined by its components. Sirrf currently offers various components in the fields of graphics and sound. Furthermore Sirrf also provides an Entity Manager which should be seen as the central interface point to all entity related issues.
• Event Management
  Sirrf’s event management is build upon sigslot. This means that Sirrf follows an observer model where objects have to subscribe to an event if they want to react to that event. Currently observers can subscribe to game logic events, input events (passed from Irrlicht) and GUI events (again, passed from Irrlicht).
• Game Management
  The Game Manager performs generic game initialization and deinitialization. It also provides functions to access sub-systems of the framework, such as the Event Manager and the Entity Manager. It’s main function, though, is to control the flow of the game through game state management. This class provides various features to this end.
• Scripting
  Sirrf is almost completely accessible through AngelScript, a free and open source scripting language. AngelScript allows users to extend applications on run-time using scripts that follow a C/C++ like syntax. Furthermore it’s easy to extend Sirrf’s AngelScript bindings even further.

You might be wondering, though, if Sirrf is really something for you. It’s obvious that Sirrf is ideal for newcomers to Irrlicht and game development, but Sirrf should also be useful for experts. Especially now experts are more than welcome as Sirrf is still in beta status.

In the coming time focus will lie primarily at adding additional documentation. This will be an crucial step to make the framework more accessible to newcomers. And of course Sirrf will also be extended with new features.

The Sirrf Project

Project name

Sirrf – Simple Irrlicht Framework

Brief description

Sirrf, the Simple Irrlicht Framework, is an extensive, but open source and simple framework for rapid game development. Sirrf provides end-users a game skeleton which implements concepts such as states, component-based entities and a datastore. Newer hobbyist game developers will probably benefit most from the project, but hopefully Sirrf will also be useful for experienced developers.

Target aim

Long term

Making a game isn’t a simple task. The goal of the Sirrf project is to create an extensive, but simple framework to enable rapid game development. Furthermore, Sirrf is aimed for as broad of a target audience as possible. Sirrf hopes to accomplish this by maintaining a cross-platform nature and a lack of genre specialization. Additionally, the framework is not-for-profit and open source, licensed under the zlib/libpng license.

Short term

At the moment the main priority is to finish the core, which will form the base for future releases. The first release is expected after Irrlicht 1.6 and AngelScript 2.17.0 are released.

Compensation

Sirrf is open to donations, but this doesn’t guarantee regular financial compensation. So expect to work largely without financial compensation.

Technology

There are no requirements for developers to use specific tools; developers are free to choose their own tools. Please note that Sirrf currently uses the following languages and APIs:

Programming Language: C++
Scripting Language: AngelScript
Rendering: Irrlicht
Sound: SFML-Audio

Talent needed

C++ Programmers

Sirrf is looking for additional programmers. Moderate knowledge of C++ is required. Knowledge of other components, such as AngelScript and Irrlicht, is preferred. You’ll work with other programmers over the SVN of Sirrf. As programmer you’ll be working on multiple different areas of the code, but it’s possible to specialize on one part of the code. Additional programmers on the following topics would be much appreciated:

- Core Development (graphics, scripting, I/O)
- Physics

Windows and Mac OSX Maintainers

Sirrf is currently only supported on Linux; maintainers for Windows and Mac OSX are needed.

Team structure

Michael Bartsch

In the past I’ve worked on several projects. The smaller projects nearly always involved some implementation of Irrlicht. My bigger projects, however, are mostly unrelated to Irrlicht. My latest project was the Aia-project, a project with the goal to create a small artificial intelligent robot. And before that I worked on Entwined Worlds, a 2D Action-RPG, that has never been released. Furthermore, I’m one of the editors of .simplicity.
