Panda3D 1.6 Game Engine Beginner's Guide

Overview of this book

Panda3D is a game engine, a framework for 3D rendering and game development for Python and C++ programs. It includes graphics, audio, I/O, collision detection, and other abilities relevant to the creation of 3D games. Also, Panda3D is Open Source and free for any purpose, including commercial ventures. This book will enable you to create finished, marketable computer games using Panda3D and other entirely open-source tools and then sell those games without paying a cent for licensing. Panda3D 1.6 Game Engine Beginner's Guide follows a logical progression from a zero start through the game development process all the way to a finished, packaged installer. Packed with examples and detailed tutorials in every section, it teaches the reader through first-hand experience. These tutorials are followed by explanations that describe what happened in the tutorial and why. You will start by setting up a workspace, and then move on to the basics of starting up Panda3D. From there, you will begin adding objects like a level and a character to the world inside Panda3D. Then the book will teach you to put the game's player in control by adding change over time and response to user input. Then you will learn how to make it possible for objects in the world to interact with each other by using collision detection and beautify your game with Panda3D's built-in filters, shaders, and texturing. Finally, you will add an interface, audio, and package it all up for the customer.

Time for action – making and importing a custom class


To start with, we're going to make a simple class for the track in our game and import it into our main file.

  1. Start by opening up the file chp04_07.py and resave it in the Chapter05 folder as WorldClass_01.py.

  2. Next, open a new blank document in Notepad++ and save it as TrackClass_01.py.

  3. In the new file, add the following lines of code at the very top:

    class Track:
      def __init__(self):
  4. The next step is to copy a few lines from WorldClass_01.py, specifically the lines where we load our track, reparent it, and reposition it. Once you've copied the lines to the clipboard, you can delete them from the WorldClass_01.py file. These are the lines we're referring to:

        self.track = loader.loadModel("../Models/Track.egg")
        self.track.reparentTo(render)
        self.track.setPos(0,0,-5)
  5. Go back to the file TrackCLass_01.py and paste the three lines into the __init__ method, like so:

    def __init__(self):
        self.track = loader.loadModel("../Models/Track...
