Cocos2d-x 自制提示框（就是游戏登陆失败之类的提示一下消失效果）

本文介绍如何使用Cocos2d-x创建提示框组件，并提供了代码实现，包括初始化、显示和移除提示框的方法。

用法简单直接create就OK了，不用添加在layer上的，感觉改成静态方法会更好的，暂时就这样先吧，静态有空在改。

直接代码了，没啥好讲的

.h文件

#pragma once

#include "cocos2d.h"

USING_NS_CC;

class HintBox : public CCLayerColor
{
public:
	HintBox(void);
	~HintBox(void);

	static HintBox* createBox(const char* content = "NULL", const ccColor4B& color = ccc4(200,200,200,200), float width = 400.0f, float high = 100.0f);

	virtual bool init(const char* content, const ccColor4B& color, float width, float high);

	virtual void onEnter();

	virtual void onExit();

	void deleteLayer(CCNode* obj);

};

#include "HintBox.h"
