pedre 0.3.0

A Python RPG framework built on Arcade with seamless Tiled map editor integration

Pedre

A Python RPG framework built on Arcade with seamless Tiled map editor integration. Build Zelda-like games with dialog systems, NPC interactions, inventory management, and event-driven scripting. Built with a plugin-based architecture that lets you replace or extend core systems without forking the engine.

Is Pedre for you?

Pedre is designed for:

• Developers who want to build 2D RPGs in Python
• Projects using Arcade + Tiled
• Games with dialog, NPCs, and scripted events

Pedre may not be a good fit if:

• You need a visual editor like Unity/Godot
• You want a low-level engine rather than a framework
• You are targeting mobile or web

Features

• Tiled Map Integration - Load .tmx maps with automatic layer detection and object parsing
• Event-Driven Scripting - JSON-based cutscenes, triggers, conditions, and actions
• NPC System - Animated NPCs with dialog trees, pathfinding, and state management
• Dialog System - Multi-page conversations with character names and text reveal animation
• Inventory System - Item collection, categorization, and photo viewing
• Portal System - Map transitions with conditional triggers and waypoint spawning
• Save/Load System - Multi-slot game state persistence with auto-save
• Pause Menu - In-game overlay with save/load, new game, and resume options
• Player Control - Animated player sprite with 8-directional movement and collision
• Camera System - Smooth camera following with target switching and bounds
• Audio System - Background music and sound effects with volume control
• Particle Effects - Visual feedback for interactions (sparkles, hearts, trails, bursts)
• Interaction System - Distance-based object and NPC interaction detection
• Physics System - Collision detection with configurable wall layers
• Pathfinding - A* pathfinding for NPC movement around obstacles
• Input Handling - Normalized movement vectors with customizable key bindings
• Debug Mode - Development overlay showing coordinates and NPC states
• Resource Caching - Efficient loading and caching of sprites, audio, and maps

Requirements

• Python 3.14+
• Arcade 3.x
• Tiled Map Editor (for map creation)
• Windows, macOS, or Linux

Installation

Install from PyPI:

pip install pedre

Or with uv:

uv add pedre

CLI

Pedre includes a command-line interface for project management:

# Initialize a new project with recommended structure
pedre init

# Initialize in a specific directory
pedre init --path ./my-game

# Validate project configuration
pedre validate

The CLI is extensible - you can add custom commands in your project's commands/ directory or via external packages. See the CLI Guide for details.

Quick Start

Create a new project:

pedre init

This creates main.py, settings.py, and the recommended directory structure. Run your game:

# main.py
from pedre import run_game

if __name__ == "__main__":
    run_game()

Customize settings:

# settings.py
SCREEN_WIDTH = 1280
SCREEN_HEIGHT = 720
WINDOW_TITLE = "My RPG"
INITIAL_MAP = "my_map.tmx"

See the Getting Started Guide for a complete tutorial covering NPCs, dialogs, scripts, portals, and more.

Architecture

Pedre uses a plugin-based architecture where plugins communicate via a central GameContext:

• GameView - Single view managing gameplay (pause menu and inventory are plugin overlays, not separate views)
• GameContext - Central coordinator providing plugins access to each other
• EventBus - Powers the event-driven scripting system (triggers and actions)
• Plugins - Modular, replaceable components for different game aspects. See Plugin Reference for complete list
• Content Registry - JSON-driven data layer for sprites, NPCs, maps, players, items, and dialogs. See Content Registry
• Extensible scripting system - Create custom actions, events, and conditions
• Sprites - AnimatedSprite with multi-directional sprite sheet support for players and NPCs

All core plugins can be replaced or extended to customize your game's behavior.

Development

Want to contribute or run from source?

# Clone the repository
git clone https://github.com/msaizar/pedre.git
cd pedre

# Install with dev dependencies
