cocos2d-x3.4json动画删除问题

在本次做毕业设计过程中，cocos studio2.0版本试用了下，导入代码啥的倒是便捷，csb唯一需要注意的是目录问题，哪怕加载csb文件时已经写了目录，也需要在代码中通过setSearchPaths添加该文件目录，否则会找不到资源。但是就本身UI编辑来说，我竟然找不到控件层级怎么调整，在属性中各种值也用不惯，动画编辑器还行，亮点也就是能直接运行了吧= =。所以自己还是守旧一点，用的cocosstudio1.6的版本了。

但是在cocos2d-x3.4中，场景切换的时候需要把cocosstudio的动画release了，否则将会造成再次进入该场景时出现野指针（即指向上个界面的动画对象），很奇怪我居然不知道，底层中只有一个releaseActions()方法，也就是会直接release所有动画，别的json的动画也会被释放，然后翻了下在公司用的底层，果然完全被改了= =。所以自己写一个根据json名来释放的方法吧：

找到CCActionManagerEx的头文件和cpp，或者直接在代码中找ActionManagerEx类中找到定义；

在

void releaseActions();

方法下边添加一个新方法：
void releaseAction(const char* jsonName);

而后在cpp中实现这个方法：

//****************在这里实现
	void ActionManagerEx::releaseAction(const char* jsonName)
	{//首先，先和获取动画一样的方式，获取出该json的动画列表
		std::string path = jsonName;
		ssize_t pos = path.find_last_of("/");
		std::string fileName = path.substr(pos + 1,fileName.c_str());
		auto iterator = _actionDic.find(fileName);
		if (iterator == _actionDic.end())
		{
			return;
		}
		auto actionList = iterator->second;//而后遍历动画列表，将该json文件每个动画停止
		for (auto & action : actionList)
		{
			action->stop();
		}
		actionList.clear();
		_actionDic.erase(fileName);
	}


}

因为暂时也就需要释放json文件所有动画，就不用继续拓展了，原本想像公司的那样，直接是传入Layout*root对象，这样就不用写json了，不过看了下公司的，太过麻烦，得改好几个文件的实现方式，斟酌下还是写个简单够用的吧= =。原文链接：https://www.f2er.com/cocos2dx/342693.html
