animations and sounds and more tools

[dawc17]

This pull request introduces a new audio engine to the project, enabling sound effects for player actions such as footsteps, block breaking, and block placing. It also adds support for multiple pickaxe types, updates the rendering logic for held items to allow for more dynamic animations, and embeds additional assets for these features. The most important changes are summarized below:

Audio Engine Integration:

• Added a new AudioEngine class with support for initializing, updating, and shutting down audio, as well as playing sounds for footsteps, block breaking, and block placing. Integrated the engine into the main game loop and player actions. (src/audio/AudioEngine.h, src/audio/AudioEngine.cpp, src/core/MainGlobals.cpp, src/core/MainGlobals.h, src/core/main.cpp, [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]
• Introduced SurfaceType and a helper function to map block IDs to surface types for context-sensitive footstep sounds. (src/audio/AudioTypes.h, src/audio/AudioTypes.hR1-R36)
• Added a C translation unit for stb_vorbis to support audio decoding. (src/audio/stb_vorbis_impl.c, src/audio/stb_vorbis_impl.cR1-R3)
• Updated CMake configuration to include new audio sources and link with additional Windows libraries for audio support. (src/CMakeLists.txt, [1] [2]

Gameplay and Animation Enhancements:

• Added new player state fields and logic for swinging and placing animations, including timers and progress tracking for smoother visual feedback. (src/gameplay/Player.h, src/gameplay/Player.cpp, src/core/main.cpp, [1] [2] [3]
• Updated held item rendering to use new animation parameters and allow for tuning of swing and place motions. (src/core/Renderer.cpp, [1] [2]

Asset and Inventory Updates:

• Embedded additional pickaxe textures and added them to the creative inventory, supporting diamond, wood, stone, gold, and iron pickaxes. (src/CMakeLists.txt, src/gameplay/Inventory.cpp, [1] [2] [3]
• Updated the asset embedding system in CMake to organize tools, blocks, and shaders more clearly. (src/CMakeLists.txt, [1] [2] [3]

These changes collectively enhance the game's immersion with audio feedback, expand the available tools, and improve the visual and interactive experience.
