An easy to use game engine/framework for python.

Getting Started

1. Install Python 3.10 or newer.

2. Open cmd/terminal and type:

pip install ursina

To get the newest, in development version from GitHub, install it like this:

pip install git+https://github.com/pokepetter/ursina.git

If you want to easily edit the source, it's recommended to clone the git repo and pip install with --editable flag like this. Make sure you have git installed.

git clone https://github.com/pokepetter/ursina.git
cd ursina
pip install --editable .

Also install any of the optional dependencies you want from the list below, or install them all with:

pip install ursina[extras]

On some systems you might have to use pip3 instead of pip in order to use Python 3 and not the old Python 2. To use a specific Python version, use:

python3.xx -m pip install ursina

Where 3.xx is the version you want to target.

Dependencies

• python 3.10+
• panda3d
• pillow, for texture manipulation
• psd-tools, for converting .psd files
• blender, for converting .blend files
• pyperclip, for copy/pasting

Examples

from ursina import *            # this will import everything we need from ursina with just one line.

app = Ursina()
ground = Entity(
    model = 'cube',
    color = color.magenta,
    z = -.1,
    y = -3,
    origin = (0, .5),
    scale = (50, 1, 10),
    collider = 'box',
    )

app.run()                       # opens a window and starts the game.

• Minecraft Clone

• Platformer Game

There are other examples in the samples folder, or in samples website

How do I make a game?

Ursina games are made by writing Python code. You can use any text editor you want, but personally I like to use Atom.

1. Create an empty .py file called ursina_game.py
2. Copy this text into your new file:

from ursina import *           # this will import everything we need from ursina with just one line.

app = Ursina()

player = Entity(
    model = 'cube' ,           # finds a 3d model by name
    color = color.orange,
    scale_y = 2
    )

def update():                  # update gets automatically called by the engine.
    player.x += held_keys['d'] * .1
    player.x -= held_keys['a'] * .1

app.run()                     # opens a window and starts the game.

1. Run this in the terminal start the game:

   python ursina_game.py
   

   ... or run it with your editor/IDE of choice.

2. You can now move the orange box around with 'a' and 'd'!

   To close the window, you can by default, press control+shift+alt+q or press the red x.
