cocos2d-x 自定义动态特效背景

由于在游戏中有时候需要用到一些特效，但是用图片生成不是很好。因此自己写了一个用于生成背景特效的类，用来生成简单的背景动画效果。

以下是源码：

BackGroundSqur.h 头文件

#ifndef __BACKGROUNDSQUR_H__
#define __BACKGROUNDSQUR_H__
#include "cocos2d.h"

USING_NS_CC;


class BackGroundSqur : public cocos2d::CCLayer
{
public:
CCDirector *Director;//导演类




CCLayer*  InitWithSprite(int Max_X, int Max_Y, const char *NameString);//带图片的初始化
CCLayer* Init(int Max_X, int Max_Y);//不带图片的初始化
CCLayer * Line();//线形背景
CCLayer * ExtendSqur();//方块扩展
void Release();
public:
static BackGroundSqur* create(int Max_X,int Max_Y);//不带图片的
static BackGroundSqur* create(int Max_X, int Max_Y, const char *NameString);//带图片的
static BackGroundSqur* LineBackGround();//线形
static BackGroundSqur* ExtendSqurBackGround();//方块扩展

}


//释放资源
void BackGroundSqur::Release()
{
this->removeAllChildren();
}

使用示例：

1.首先导入头文件

#include "BackGroundSqur.h"

2.实例化一个类，并添加一个层。

//加载背景
//BackGroundSqur *backsqur = BackGroundSqur::create(Num_X, Num_Y, "triangle.png");//用自定义图片加载背景特效
//BackGroundSqur *backsqur = BackGroundSqur::create(Num_X, Num_Y);//默认的方块背景动画特效
//BackGroundSqur *backsqur = BackGroundSqur::LineBackGround();//默认的线形背景动画特效
BackGroundSqur *backsqur = BackGroundSqur::ExtendSqurBackGround();//默认的方块扩展动画特效
CCLayer *layer = backsqur;
addChild(layer, 0);

参数说明：NUM_X : x方向最大的精灵数量。

   Num_Y: y方向上最大的精灵数量。

 第三个参数为你需要自己加载的图片路径。推荐图片尺寸为50*50。

注意：如果您需要释放掉背景动画的精灵资源，请调用

backsqur->Release();//释放背景层资源即可
