polystack-pygame-engine 1.2.3

A modular pygame_engine library for Pygame-based 2D games.

Pygame-Engine

Overview

Pygame-Engine is a lightweight, Unity-inspired game engine built using Python and Pygame. It provides a modular and extensible framework for 2D game development, including GameObjects, Components, Scene Management, Event Handling, and more.

---

Features

• GameObject System: Modular entities with components like Transform, SpriteRenderer, and Collider.
• Scene Management: Easily manage and transition between game scenes.
• Prefab System: Save and instantiate reusable GameObject templates.
• Event System: Decoupled communication via a publish-subscribe model.
• Input Manager: Centralized input handling with customizable key bindings.
• Scriptable Objects: Reusable and serializable data containers for configurations and items.

Usage

GameObject System

Create GameObjects and add Components:

from engine.game_object import GameObject
from engine.components import Transform, SpriteRenderer

player = GameObject("Player")
player_transform = player.add_component(Transform)
player_renderer = player.add_component(SpriteRenderer)
player_transform.position = [100, 100]

Scene Management

Switch between scenes or reset the current scene:

from engine.scene_manager import SceneManager
from engine.scene import Scene

main_scene = Scene("MainScene")
SceneManager.load_scene(main_scene)
SceneManager.reset_scene()

Prefab System

Save and instantiate reusable prefabs:

from engine.prefab_system import PrefabSystem

PrefabSystem.save_prefab("PlayerPrefab", "player_prefab.json", player)
new_player = PrefabSystem.instantiate_prefab("player_prefab.json")

Event System

Publish and subscribe to events:

from engine.event_system import EventBus

EventBus.subscribe("player_died", lambda score: print(f"Player died with score {score}"))
EventBus.publish("player_died", score=100)

Input Manager

Bind keys to actions:

from engine.input_manager import InputManager

InputManager.bind_action("jump", pygame.K_SPACE, "down")
InputManager.register_callback("jump", lambda: print("Jump!"))
