Simple — Pro‑Ready Python Game Engine
Github Project
Simple is a fast, modern game/animation engine built for Python developers who want real engine power without the heavyweight setup. It’s designed to feel pro from day one:
- Python-first workflow (
import simple) with a clean, friendly API
- C++/OpenGL 3.3 core for speed, rendering, and the main loop
- A lightweight editor for
.sim projects with Play‑in‑Editor
Quick start (10 lines)
from simple import Scene, Cube
scene = Scene()
cube = Cube()
scene.add(cube)
scene.run()
Why Simple
- Ridiculously fast to start: visible results in under 10 lines
- Built for creators: editor + runtime in the same ecosystem
- Performance without the pain: C++ core, Python simplicity
- Small‑team friendly: minimal setup, modern engine features
What you get (out of the box)
- Rendering: lit 3D cubes (Phong-ish directional light), optional textures (
.ppm)
- Scene system:
Scene + entities (Cube)
- Camera: view + perspective projection
- Input: keyboard + mouse (GLFW)
- HUD:
scene.draw_text(...)
- Debug gizmos:
scene.draw_line3d(...)
- Screenshots:
scene.screenshot("frame.ppm")
- Editor: create/open
.sim projects, edit objects, Play, Auto Reload
