Objects can be static, moving but not forced (kinematic), and dynamic (dynamic ). This is the definition of the object type:B2_staticbody Static objects do not move during simulation, as if they have infinite quality. In box2d, the quality of static object

The native box2d is written in C ++. However, because of the awesome engine, it has been transplanted to multiple language platforms, such as flash, Java, js, C #, and python. Since I used cocos2d-x to develop the game, so we learn C ++ version, first set up the box2d environment. The latest version of box2d is 2.3.0 ,. This version has completed the vs2012 an

Cocos2d-x is embedded with the chipmunk and box2d two physical libraries, chipmunk is enabled by default. If you want to use box2d, you can do the following settings. PS: I use the version is cocos2d-x-2.2.5.One, set enable box2d in Visual Studio.You typically create a project by using the Python command under the tools/project-creator/folder in the Cocos2d-x hom

I wanted to do a simple game exercise, but I was too busy (and too lazy) to continue. Share the code now. Don't spray it, don't hit it! For more information, see. Feeling: box2d is the engine of the physical world. It seems that the game runs slowly a

In box2d, collision events are implemented by implementing b2contactlistener class functions. b2contactlistener is an abstract class provided by box2d, and its abstract function:Virtual void begincontact (b2contact * contact ). The two objects will respond when they begin to contact each other, but they are called only once.Virtual void endcontact (b2contact * contact ). Response when splitting. But it is c

Previous review This famous saying goes:Good wood does not grow in good condition; the stronger the wind, the stronger the tree.[Mariote] In the previous article, we learned about the body class in the dynamics module, covering everything from definition to creation and usage. This is actually a problem (this is done later in this article ). Continue to learn the classes in the dynamics module. This time we will learn the fixture class. Introduction We know that shape can be used independently

From: http://hi.baidu.com/goodlad/blog/item/80e8613680381acba2cc2beb.html 1. helloworld Before that, I assume that you have read the source code of helloworld, read the instructions about helloworld in the user manual, and have understood most of the content. In fact, helloworld has already described the operating mechanism of the box2d physical engine in an extremely simple language. We can summarize the steps below: 1. Create a world based on a b2a

Attributes such as the shape, size, material, density, and elasticity of an object are described by the customizer (fixture) and translated into a fixture. After an object is collided, it will respond according to its own customizer. The main attributes of the customizer are as follows: -Shape -Elasticity -Friction -Density Collision between objects depends on the shape of the object. box2d can define the arc, rectangle, and polygon. {// Circular bod

Since there is a cocos2d-x, why Box2d it, because the cocos2d-x as an image engine, just used to display the image, the image can be any coincidence between, If You Want To Do similar physics collision and other motion effect, box2d is used to simulate objects in the physical world; This article describes how to create dynamic objects, static objects, floating objects, and their binding to images; The follo

This tutorial is based on the Child Dragon Mountain Man translation cocos2d iPhone tutorial, rewrite with cocos2d-x for xNa engine, plus some of my processing and production. In the tutorial, most of the text images are from the original author and the author of the translation, Long Shan, and many others are my own understandings and processing. I would like to thank the original author for his tutorial and the translation of Zilong shangren. This tutorial is only for learning and communication

Example introduction to Box2D physical engine in Cocos2d-x: Using JointsNext we will use Box2D physical engine technology for refactoring. This allows you to understand how to use joint constraints in Box2D.The code for using joints in HelloWorldScene. cpp is as follows: Void HelloWorld: addNewSpriteAtPosition (Vec2 p) {log (Add sprite % 0.2f x % 02.f, p. x, p. y); // create the physical engine genie object

Cocos2d-x Study Notes (20) -- box2d getting startedBefore reading this article, you 'd better read the self-taught notes of the box2d physical engine I wrote. 1.
