Open Source Objective C Game Development Frameworks

A C++ object orientated 2D game engine for Windows, Mac OS, Linux and iPhone.

A library for the iPhone that allows you to specify bezier curves and splines for use in games and other applications that might need to draw and manipulate curves passing through an arbitrary set of points (e.g. Catmull-Rom splines).

Ethanon is a 2D game engine focused on the recent video cards for hardware acceleration and shader effects. The engine provides high-quality light an shadow effects with an easy visual interface and a simple and direct scripting system.

Macchiato Doppio is a Java game engine emphasizing cross-platform interoperability, and 2D and 3D support. We've just re-created the foundation of the game engine, and we're working on making things easier with more advanced tools and documentation. Currently we're focused on 2D gaming, but we'll be moving on to 3D gaming when we've got a good, tested 2D platform working.

RenderTools is an OpenGL based scenegraph library in C++ for Windows, OSX and IOS supporting OpenGL|ES1.1, ES2.0, OpenGL1.5 and up to the latest version (currently 4.2). It allows the developer to easily (de)serialize a scenegraph to-and-from xml, create renderbuffers, framebuffers, samplers, vertexbuffers etc. and cross-reference those items. RenderTools allows you to completely specify an application, its resources, viewcontrollers and its renderpasses in one single xml. GraphNodes such as RelationalNode, RenderNode, and TransformNode can be used to create a complex hierarchy for rendering. Both update and render calls can selectively include or exclude specific components such as geometric details or lighting or texturing.

SimKit(because GameKit was taken) is designed to allow quick and easy cross platform abstraction away from platform dependant drawing and physics libraries. The APIs provide a generic way to make common calls for drawing, animating, and otherwise manipulating 3D entities, as well as shading and texture information.

A royalty free BSD licensed mobile device targeted 2D/3D game engine written in C/ObjC using OpenGL & OpenAL. Blender export scripts, png/pvrtc/ogg/ttf/bmp/wav loaders, XML asset manifesting /w desktop editor, Lua scripting, supports iPhone SDK.
