Powered by Python

Python is the world's most popular programming language for a reason. The ease of use of Python combined with ursina's design, makes it easy to write concise code and avoid lots of boilerplate code.

from ursina import * app = Ursina() cube = Entity(model='cube', color=hsv(300,1,1), scale=2, collider='box') def spin(): cube.animate('rotation_y', cube.rotation_y+360, duration=2, curve=curve.in_out_expo) cube.on_click = spin EditorCamera() # add camera controls for orbiting and moving the camera app.run()

Make Any Type of Game

2D games, 3D games, applications, visualizations, you can make anything you want with ursina.

Iterate Faster

• Reload code/textures/models while in-game
• Automatic import of .psd and .blend files
• Compile times:

Iteration speed benchmark. Time from code/scene change to play. Game: pong clone. Lower is better.
