Obsidian Engine

Obsidian is a high-performance 2D game engine designed specifically for CC: Tweaked. It features a robust Entity Component System (ECS), an optimized rendering pipeline with double-buffering, and a flexible particle system.

Features

• High-Performance Rendering: Uses double-buffering and term.blit optimization to ensure smooth frame rates.
• ECS Architecture: Decoupled logic and data for scalable game development.
• Asset Management: Automatic caching and pre-processing of sprites (.osf), UI layouts (.oui), and emitters (.ope).
• Particle System: Fully integrated ECS-based particles with support for gravity, drag, and color/character interpolation.
• Static/Dynamic Layering: Optimized handling of static backgrounds versus dynamic entities.

Project Structure

• src/core/: The heart of the engine.
  • loader.lua: Handles asset loading and optimization.
  • particles.lua: ECS systems for particle effects.
  • buffer.lua: Low-level rendering logic (Double-Buffering).
• assets/: Suggested directory for your .osf and .ope files.

Rendering Pipeline

The engine follows a strict 7-phase pipeline:

1. Clear Phase
2. Static Pass
3. Query Pass (ECS)
4. Sort Pass (Z-Indexing)
5. Entity Pass
6. UI Pass
7. Present Phase (Sync to Hardware)
