How to Print to the Console in Blender

Have you ever wondered how to print messages to the console in Blender? In this tutorial, we will guide you through the process step by step. Printing messages to the console can be a helpful way to debug your scripts and see the output of your code in real-time. Let's dive in!

Changing from Default to Game Logic

First, let's switch from the default Blender mode to the game logic view. Follow these steps:

  1. Click on the 'default' dropdown menu.
  2. Select 'game logic' from the options.

Adding Sensors, Controllers, and Python Script

With the cube selected, let's add sensors, controllers, and a Python script:

  1. Add a sensor by clicking the first three dots and selecting 'add sensor.'
  2. Add a controller by clicking 'add controller' and choosing 'Python.'
  3. Create a new script by clicking on 'new' in the script tab.
  4. Type the following code snippet into the script editor:
print("Hello, world!")

Viewing the Console Output

To view the console output, follow these steps:

  1. Drag the script into the Blender window.
  2. Toggle the system console to full screen.
    • On Linux: Open the console from the terminal window.
    • On Mac: Apologies, this step is not covered in this tutorial.
  3. Run the script by hovering your mouse over the game engine and pressing the 'P' key.

Printing Multiple Items

You can print multiple items by separating them with a comma. For example:

print("Hello, world!", 0)

Using Variables in Printing

Let's demonstrate how to use variables in printing messages:

  1. Set a variable called 'word' to a value, for example, 10.
  2. Update the print statement in the script to include the variable:
word = 10
print("Hello, world!", word)
  1. Run the script again to see the updated output.

Summary

In conclusion, printing messages to the console in Blender is a useful tool for debugging and monitoring your scripts. By following these simple steps, you can visualize the output of your code efficiently. If you have any questions or thoughts, feel free to leave them in the comments below.
