cocos2d-x游戏开发(九)重要的基类CCNode

Cocos2d-x 前端之家
前端之家收集整理的这篇文章主要介绍了cocos2d-x游戏开发(九)重要的基类CCNode，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

这个CCNode是个很重要的基类，没有理由不把它搞一搞。

首先看下类结构图：


它几乎是所有类的基类，官方注释如下：


CCNode是主要元素。任何一个能被绘制或者包含能被绘制的东西都是一个CCNode。

最常用的CCNode有：CCScene,CCLayer,CCSprite,CCMenu.

一个CCNode的主要特性包括：

1.他们能够容纳别的CCNode节点，别如能addChild,getChildByTag,removeChild 。

2.他们能定期的调度回调函数，比如能schedule，unschedule等。

3.他们能执行动作，比如runAciton，stopAction等。

一些节点能给自己或他们的子几点提供一些额外额功能。


继承一个CCNode节点通常意味着如下几条：

1.重写init()函数来初始化资源和回调

2.创建回调函数来处理时间片

3.重写draw来绘制节点

另外，一个CCNode是一个看不见对象，他没有纹理。每个节点都有一个Camera，默认指向节点的中心点。

看下这个类
