Aspis Engine

The Lightweight Python Game Engine

Aspis Engine is a modern, cross-platform 2D game engine built for rapid prototyping and flexibility. Powered by Python 3, PySide6, and Pygame, it offers a familiar and powerful environment for developers to create 2D games without the overhead of massive commercial engines.

Features

Visual Editor

• Scene Composition: Drag-and-drop hierarchy management.
• Inspector: Real-time property editing for all components.
• Asset Browser: Built-in file management for scripts, sprites, and scenes.
• Gizmos: Visual aids for colliders and transforms.

Python Scripting

• Native Python: Write game logic in standard Python files (.py).
• Hot-Reloading: Edit scripts while the editor runs (limited support).
• API: Simple, intuitive API for start(), update(dt), and component access.

Entity-Component-System (ECS)

• Flexible Design: Compose complex behaviors by attaching simple, single-purpose components.
• Performance: Logic is decoupled from data, allowing for optimized processing.

Physics Engine

• Pymunk Integration: Robust 2D rigid body physics.
• Collision Detection: Box and Circle colliders with continuous collision detection (CCD).
• Dynamics: Gravity, friction, restitution (bounciness), and drag.

Rendering

• Sprite Renderer: High-performance 2D sprite rendering with tinting and layering.
• Text Rendering: Dynamic text support with caching optimization.
• Camera System: Zoomable, movable 2D cameras with smooth tracking.

Getting Started (Source)

If you prefer to run from source or contribute to the engine:

1. Clone the repository.

2. Install dependencies:

   pip install -r requirements.txt

3. Run the Editor:

   python editor/app.py

4. Run a Scene Directly:

   python run_demo.py

   Or run a custom scene:

   python run_demo.py scenes/animation_demo.scene.json

Documentation & Demos

• Demos: Check the scenes/ folder for demo scenes (knight_demo.scene.json and animation_demo.scene.json).
• Source Code: The codebase is modular and documented, serving as the primary reference for advanced users.
