## Description

cocos2d-objc is an Objective-C 2D game engine designed for developing interactive games and applications. It serves as a cross-platform game framework that enables the deployment of a shared codebase across iOS, tvOS, and macOS.

The project features a hardware-accelerated 2D renderer utilizing OpenGL and Metal to display sprites, tile maps, and particle effects. It includes a dedicated OpenAL audio engine for managing music and spatialized sound effects, alongside a cross-platform input handler for processing touch, mouse, keyboard, and accelerometer events.

The framework provides capabilities for game physics integration to simulate rigid body dynamics, as well as tools for creating orthogonal, isometric, or hexagonal tile maps. Additional features cover scene management with custom visual transitions, the generation of particle systems, and the implementation of user interfaces with native touch interaction.

The system supports platform-specific content scaling to load images based on device resolution, reducing binary installation size for the Apple ecosystem.
