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 – customizing the mouse cursor


In this case, it will be easier to let the process explain itself, so let's dive right in.

  1. Open WorldClass_02.py.

  2. Add this line of code to our imports. While we're here, let's update our imports to use RaceClass_01.py instead of RaceClass_00.py.

    from pandac.PandaModules import *
  3. Scroll down to the __init__ method and add this block of code right at the top of the method:

    cursor = loader.loadModel("../Models/Cursor.egg")
        cursor.reparentTo(render2d)
        cursor.setBin("gui-popup", 100)
        cursor.hide()
        
        props = WindowProperties()
        props.setCursorHidden(True)
        base.win.requestProperties(props)
        base.mouseWatcherNode.setGeometry(cursor.node())
        self.totalItems = len(self.models)
  4. Next, scroll down to the line where we instantiate an instance of our Race class. Change that line to include a new argument:

    self.race = Race(self.inputManager, hud, cursor)
  5. Resave the file as WorldClass_03.py and open RaceClass_00.py.

  6. Rewrite the definition...
