Unity is a popular game development platform that supports both C and Python programming languages. In this article, we will explore how to create games in Unity using Python.
Prerequisites
Before we dive into creating games in Unity using Python, it’s important to ensure you have the following prerequisites:
- A computer with the latest version of Unity installed
- Familiarity with basic programming concepts in Python
- A basic understanding of game development principles and mechanics
Installing Python for Unity
To use Python in your Unity project, you’ll need to install the necessary tools and libraries. Here are the steps to follow:
- Open Unity and create a new project or open an existing one.
- Go to Assets > Scripts > New C Script and rename it to "PythonScript". This will be the entry point for our Python code.
- In the project settings, go to Build Settings > Player Settings and enable the "Allow Scripts from Assets" option under the Scripting section.
- Close Unity and open your command prompt or terminal window.
- Navigate to the Unity project directory and run the following command to install the Python package for Unity:
bash
pip install –upgrade -r requirements.txt
This will install any necessary packages required by your Python script.
- Open your PythonScript file in a text editor or IDE of your choice and add the following code to import the necessary modules and set up a basic game loop:
import unity
from unity import *
def main():
Set up a basic game loop
while True:
Update input and physics here
Render your game objects here
unity.wait_for_frames(1/60) Wait for 60 frames per second
if __name__ ‘__main__’:
main()
This code will set up a basic game loop that updates input and physics every frame and renders your game objects on the screen.
Writing Your First Python Script
Now that you have set up the basic game loop, it’s time to write your first Python script. Let’s create a simple 2D platformer game:
- Create a new asset in Unity by going to Assets > Create > GameObject and name it "Player".
- Add a Rigidbody component to the Player game object. You can do this by right-clicking on the Player game object in the Hierarchy window and selecting "Add Component" > "Physics" > "Rigidbody".
- Create a new asset for the player’s sprite by going to Assets > Create > Sprite Renderer. Name it "PlayerSprite".
- Drag the PlayerSprite onto the Player game object in the Hierarchy window.
- Add a BoxCollider component to the Player game object. You can do this by right-clicking on the Player game object in the Hierarchy window and selecting "Add Component" > "Physics" > "Box Collider".
- Create a new asset for the ground by going to Assets > Create > Mesh Renderer. Name it "Ground".
- Drag the Ground mesh onto the ground game object in the Hierarchy window.
- Add a BoxCollider component to the Ground game object. You can do this by right-clicking on the Ground game object in the Hierarchy window and selecting "Add Component" > "Physics" > "Box Collider".
- Create a new asset for your game’s main camera by going to Assets > Create > Camera. Name it "MainCamera".
