Pyroquad Game Engine

This is a Python game engine based on macroquad.

• Install via pip install pyroquad
• Requires Python >= 3.9
• Supported Platforms: windows, linux, mac, (wasm eventually)

Featuring 2D:

and 3D:

How to build:

1. Prerequesites:

   • Python >= 3.9 ( python >= 3.14 is recommended)

   • Rust Compiler >= 1.85.0 (Required for the Rust 2024 Edition)

   • System libraries if using Linux (required for X11, OpenGL, and audio bindings):

     Ubuntu / Debian: sudo apt-get install -y libasound2-dev libx11-dev libxi-dev libgl1-mesa-dev libxcursor-dev libxinerama-dev libxrandr-dev

     Fedora: sudo dnf install alsa-lib-devel libX11-devel libXi-devel mesa-libGL-devel libXcursor-devel libXinerama-devel libXrandr-devel

     Arch Linux: sudo pacman -S alsa-lib libx11 libxi mesa libxcursor libxinerama libxrandr

2. Create and activate a Python virtual environment:

   • macOS / Linux:

     python3 -m venv .venv

     source .venv/bin/activate

   • Windows:

     python -m venv .venv

     .venv\Scripts\activate

3. Install the maturin build tool using pip install maturin

4. (optional) Run cargo run --bin stub_gen --no-default-features --features use-real to gennerate up-to-date python stubs in init.pyi.

   Stub generation specifically requires python >= 3.10

5. Compilation:

   run maturin build --release --features abi_39 for python >= 3.9

   run maturin build --release --features abi_310 for python >= 3.10

   run maturin build --release --features abi_314 for python >= 3.14

   (Note: Older ABIs offer better backward compatibility, but newer versions yield performance improvements)

6. Installation:

   • The generated package can be found at: /target/wheels/
   • Install the package: pip install \path\to\your\file.whl --force-reinstall

Example Code:

Hello rectangle

from pyroquad import *

activate_engine()

while True:
    draw_rectangle(x=100, y=100, w=600, h=300, color=Color.GREEN)
    draw_text(text="Hello rectangle", x=200, y=200, font_size=50, color=Color.RED)
    next_frame()
    examples.limit_fps(60)

Textures

from pyroquad import *

activate_engine()

texture =  Loading.download_file(
    "https://raw.githubusercontent.com/Ludwig-000/pyroquad/main/docs/PyroquadLogo.png"
).to_Texture2D()

while True:
    draw_texture(texture)
    next_frame()
    examples.limit_fps(60)

Cube

from pyroquad import *

activate_engine()

cube = Cube(
    position=Vec3.ZERO,
    rotation=Vec3.ZERO,
    scale=Vec3.ONE,
    color=Color.RED)

cam = Camera3D(position=Vec3.splat(2), target=Vec3.ZERO)

while True:
    cam.set_camera()
    cube.rot += get_delta_time()
    draw_all_objects()
    next_frame()
    examples.limit_fps(60)

Skybox

from pyroquad import *

activate_engine()


skybox_tex = examples.loading_screen_future(
    lambda a: download_file_future(a),
    ["https://raw.githubusercontent.com/Ludwig-000/pyroquad/main/tests/HDR_blue_nebulae_2.png"],
    show_rotating_square=True
)[0].to_Texture2D()

player = examples.PlayerCamera(position=Vec3.ONE)

while True:
    if KeyCode.Escape in get_keys_pressed():
        break

    player.update()
    draw_skybox(skybox_tex)
    draw_grid(
        slices=1_000,
        spacing=1.0,
        axes_color=Color.YELLOW,
        other_color=Color.GREEN)

    next_frame()
    examples.limit_fps(60)

Multiple windows

import multiprocessing
from pyroquad import *

def task(message, color_name):
    activate_engine()
    prevent_quit()
    color = getattr(Color, color_name)
    
    while not is_quit_requested():
        clear_background(color)
        draw_text(message, 200, 200, Color.GREEN, 60)
        next_frame()
        examples.limit_fps(60)

if __name__ == "__main__":
    seq_data = [("multiple", "YELLOW"), ("windows", "BRICK"), ("using", "ORANGE")]
    for msg, color in seq_data:
        p = multiprocessing.Process(target=task, args=(msg, color))
        p.start()
        p.join()

    procs = [multiprocessing.Process(target=task, args=("multiprocessing", "BLUE")) for _ in range(5)]
    for p in procs: p.start()
    for p in procs: p.join()

Rectangle deletes itself (heartbreaking)

from pyroquad import *

activate_engine()

re = Rectangle(Vec2.splat(200), 0, Vec2.splat(100), Color.WHITE)

timer  = 120
def t(rec: Rectangle):
    global timer, re
    timer-= 1
    if timer == 0:
        del(re)
    rec.draw()

re.tick(t)

while True:
    next_frame()
    examples.limit_fps(60)
