raylib-software 6.0.1.0

Python CFFI bindings for Raylib

Python Bindings for Raylib 6.0

Libraries: raymath, raygui, rlgl, physac and GLFW

Backends: Desktop, SDL, DRM, Web, Software rendering

Platforms: Windows, Mac, Linux, Raspberry Pi, Web

HELP WANTED: writing examples

Features:

• CFFI API static bindings.
• Automatically generated to be as close as possible to original Raylib.
• Faster, fewer bugs and easier to maintain than ctypes.
• Commercial-friendly license.
• Docstrings and auto-completion.
• Type checking with Mypy

Quickstart

pip3 install raylib==6.0.1.0 --break-system-packages

from pyray import *
init_window(800, 450, "Hello")
while not window_should_close():
    begin_drawing()
    clear_background(WHITE)
    draw_text("Hello world", 190, 200, 20, VIOLET)
    end_drawing()
close_window()

Installation

If you are on a modern Linux you will probably want to create a venv:

python3 -m venv venv
source venv/bin/activate

Then make sure you have the latest pip installed:

python3 -m pip install --upgrade pip

Then install

python3 -m pip install setuptools
python3 -m pip install raylib==6.0.1.0

On most platforms it should install a binary wheel. If yours isn't available then pip will attempt to build from source, in which case you will need to have Raylib development libs installed, e.g. using homebrew, apt, etc.

Windows

Binaries require x64 or x86 Windows 10 or newer.

Use an official Windows Python release rather than WSL, MSYS, etc.

MacOS

Binaries require:

• arm64 MacOS 14
• x64 MacOS 10.13, or newer.

Older MacOS requires building from source but this is usually simple:

brew install pkg-config
brew install raylib
python3 -m pip install raylib==6.0.1.0

Linux

Binaries require OS newer than Ubuntu 2016, x64/x86 or Ubuntu 2022 arm64. Otherwise build from source. (Pip should attempt automatically but will need Raylib itself installed and also pkg-config.)

The arm64 binaries are built on Raspberry Pi arm64 Bullseye with OpenGL 2.0 so may not work on other boards.

Backends

Dynamic binding version

There is now a separate dynamic version of this binding:

python3 -m pip uninstall raylib
python3 -m pip install raylib_dynamic

It works on some systems where the static version doesn't, but be sure to read these caveats before using it

You can't have multiple raylib packages installed at once.

SDL backend

This is not well tested but has better support for controllers:

python3 -m pip uninstall raylib
python3 -m pip install raylib_sdl

You can't have multiple raylib packages installed at once.

DRM backend

This uses the Linux framebuffer for devices that don't run X11/Wayland:

python3 -m pip uninstall raylib
python3 -m pip install raylib_drm

You can't have multiple raylib packages installed at once.

Problems?

If it doesn't work, try to build manually.. If that works then submit an issue to let us know what you did.

If you need help you can try asking on our discord. There is also a large Raylib discord for issues that are not Python-specific.

If it still doesn't work, submit an issue.

How to use

There are two modules in the raylib package, raylib and pyray. (There is no separate package for pyray. Do not pip install pyray). You can use either or both:

If you are familiar with C coding and the Raylib C library and you want to use an exact copy of the C API

Use the raylib module.

If you prefer a more Pythonistic API

Use the pyray module.

Running in a web browser

Pygbag >=0.8.7 supports running in a web browser. Usually the latest git version is recommended.

Make a folder my_project with a file main.py:

# /// script
# dependencies = [
#     "cffi",
#     "raylib"
# ]
# ///
import asyncio
import platform
from pyray import *

async def main():   # You MUST have an async main function
    init_window(500, 500, "Hello")
    platform.window.window_resize()  # You MAY want to add this line
    while not window_should_close():
        begin_drawing()
        clear_background(WHITE)
        draw_text("Hello world", 190, 200, 20, VIOLET)
        end_drawing()
        await asyncio.sleep(0) # You MUST call this in your main loop
    close_window()

asyncio.run(main())

Then to create the web files and launch a web server:

python3.12 -m pip install --user --upgrade pygbag
python3.12 -m pygbag --PYBUILD 3.12 --ume_block 0 --template noctx.tmpl --git my_project

Point your browser to http://localhost:8000

Some features may not work, so you can disable them like this:

if platform.system() != "Emscripten":  # audio may not work on current version of emscripten
    init_audio_device()

This is all done by Pygbag rather than by me, so you should probably contact them with any issues. Carefully read all their documentation.

It does work for most of these examples

Startup without printing anything

import logging
logging.basicConfig(level=logging.ERROR)
import pyray
pyray.set_trace_log_level(pyray.LOG_ERROR)
pyray.init_window(100,100,"test")

Performance

If you need more performance, do in this order:

1. Use Pypy rather than standard CPython. It is much, much faster and will make more difference than any other optimisations you might do.

2. Every call to C is costly, so it's slightly faster if you use Python data structures and functions when calculating in your update loop and then only convert them to C data structures when you have to call the C functions for drawing.

3. The raylib.* functions are potentially slightly faster than the pyray.* equivalents, so if you need a tiny bit more performance you can switch your inner loop functions to these.

4. There is a version of Python that is faster than Pypy: GraalPy. However it's not fully compatible with all Python packages. It doesn't work with CFFI and so doesn't work with this binding. But it is compatible with the Java binding, Jaylib! There is an example of this here: https://github.com/electronstudio/megabunny/tree/master/raylib-python-jaylib

Packaging your app

You can create a standalone binary using the Nuitka compiler. For example, here is how to package Bunnymark:

pip3 install nuitka
cd examples/textures
python3 -m nuitka --onefile --linux-onefile-icon resources/wabbit_alpha.png textures_bunnymark.py

Hall of shame!

Apparently comma.ai are now using raylib-python-cffi commercially and so have begun donating money to raylib but have chosen not to give anything to raylib-python-cffi. Yes it's perfectly legal usage, but it's not very nice behaviour. 😔
