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.

Removing tasks from the task manager


We've already talked about one method for removing tasks that we don't want running anymore. We can return task.done to end a task permanently. There are other methods we can use as well, so let's talk about them now.

There may come a time when we need to remove a task from outside the task in question. In this case, task.done doesn't help us at all. The task manager comes equipped with two methods, called remove and removeTasksMatching to help us out with this. Both of these methods operate on task names. remove requires the exact name of the task we wish to remove, but removeTasksMatching can use a partial task name with wild cards to remove a group of tasks. Both methods remove all tasks that match the given name, so if multiple tasks have the exact same name either method can remove all of them at once. Here is what the calls look like:

taskMgr.remove("My Task Name")
taskMgr.removeTasksMatching("My Task *")
