grafyte 0.3.2

A simple rendering engine with some game engine features made with OpenGL for Python

Grafyte

Grafyte is a lightweight and simple 2D game engine written in C++ with OpenGL and exposed to Python using pybind11. It aims to provide a fast and easy-to-use interface for creating 2D games and interactive applications.

Features

• Simple API: Designed for ease of use with a straightforward Pythonic interface.
• Fast Rendering: Core engine written in C++ using OpenGL.
• 2D Sprites: Support for textures and colored objects.
• Text Rendering: Easy text display with scale and color control.
• Simple Collision System: Integrated AABB-based collision detection with automatic resolution.
• Input Management: Easy-to-use action-based input system with support for keyboard triggers (Press, Hold, Release).
• Scene-based Workflow: Manage game objects within scenes.

Installation

To install grafyte, run the following command in your terminal:

python -m pip install grafyte

Building from Source

Prerequisites

• Python 3.10+
• A C++ compiler (MSVC, GCC, or Clang)
• CMake
• OpenGL drivers

[!NOTE] When applicable, please make sure to test your code on both windows and linux as well as on Python 3.10 to 3.14 if possible.

Build

To set up the development environment and build Grafyte:

Windows:

scripts\setup.bat
.\.venv\Scripts\activate
pip install .

Linux:

chmod +x scripts/setup.sh
./scripts/setup.sh
source .venv/bin/activate
pip install .

Finally, you can build the python extension using CMake:

mkdir build
cd build
cmake ..
cmake --build .

Quick Start

Here's a minimal example to get you started:

import grafyte
from grafyte import Key, InputTrigger

# Initialize application
app = grafyte.Application("My Game", (800, 600))
scene = app.make_new_scene()

# Create a player object
player = scene.spawn_object((0, 0), (50, 50))
player.color = (0, 255, 0), 1.0

# Register an action
app.input.create_action("move_right", InputTrigger.Hold, Key.D)

while not app.should_close():
    dt = app.dt

    # Handle input
    if app.input["move_right"]:
        player.pos.x += 100 * dt

    # Render scene
    app.render()

app.quit()
