Blender Python Tutorial: Printing to Console

In this Blender Python tutorial, we will learn how to print information to the console or terminal using Python scripts in the Blender Game Engine. This capability is crucial for debugging and monitoring outputs while developing your game. Let's dive into the details step by step.

Starting Blender from the Terminal

To ensure that any error output goes directly to the terminal, it's recommended to start Blender from the terminal. This applies to all operating systems, including Windows where it opens the terminal by default. Separately, the Python console is distinct and not where the output from the game engine scripts will be displayed.

Writing a Simple Print Script

Let's begin by creating a Python script that prints a basic message to the console. Follow these steps:

Open the text editor in Blender.
Create a new text file and name it, for example, "my_print".
Import the Blender Game Engine by adding import bge to the script.
Define the main function and set up a controller.
Within the main function, use the print() function to display "Hello, world" in the console.
Run the script and link it to an object in the game engine logic editor.

Displaying Object Information

Taking it a step further, let's print more than just a string. We can output specific information about objects in the scene. Here's an example:

Access the object linked to the script using owner = controller.owner.
Print the local position of the object using print(owner.localPosition).
Enhance the output by combining strings with object attributes. For instance, print the object's x-position specifically.

Running and Observing

After setting up the script, linking it to an object in the logic editor, and running the game engine, you can observe the console displaying the printed information. See the changes in real-time as the script executes.

Conclusion

Learning how to print to the console in Blender using Python scripts is a valuable skill for game developers. It helps in monitoring and debugging game logic efficiently. Experiment with different outputs and explore the vast possibilities of utilizing console printing in game development.
