cocos 3.2游戏暂停功能

<方法1>自写递归暂停类

1，GamePauseUtils.h

//
//  GamePauseUtils.h
//  AdventureKing
//
//  Created by jianan on 15/5/12.
//
//

#ifndef __AdventureKing__GamePauseUtils__
#define __AdventureKing__GamePauseUtils__

#include "cocos2d.h"
USING_NS_CC;

//操作类型
typedef enum OPERATE_TYPE{
OPERATE_TYPE_PAUSE,
OPERATE_TYPE_RESUME
}OPERATE_TYPE;

//
class GamePauseUtils
{
public:
GamePauseUtils();
~GamePauseUtils();
static GamePauseUtils* getInstance();
void operateAllSchedulerAndActions(Node* node, OPERATE_TYPE type, int ignoreTag); //忽略检测的tag
};

#endif /* defined(__AdventureKing__GamePauseUtils__) */

2，GamePauseUtils.cpp

//
//  GamePauseUtils.cpp
//  AdventureKing
//
//  Created by jianan on 15/5/12.
//
//

#include "GamePauseUtils.h"

static GamePauseUtils* instance = NULL;

GamePauseUtils::GamePauseUtils(){

}

GamePauseUtils::~GamePauseUtils(){

}

GamePauseUtils* GamePauseUtils::getInstance(){
if(instance == NULL){
instance = new GamePauseUtils();
}
return instance;
}

void GamePauseUtils::operateAllSchedulerAndActions(Node* node, OPERATE_TYPE type, int ignoreTag){
if(node->isRunning()){
switch(type){
case OPERATE_TYPE_PAUSE:
node->pause();
break;
case OPERATE_TYPE_RESUME:
node->resume();
break;
}

Vector<Node*> array = node->getChildren();

if(array.size() > 0){
for(Vector<Node*>::iterator iter = array.begin(); iter != array.end();){
Node* child = *iter;

if(child->getTag() == ignoreTag){
iter++;
}else{
iter++;
this->operateAllSchedulerAndActions(child, type, ignoreTag);
}
}
}
}
}

3，暂停

GamePauseUtils::getInstance()->operateAllSchedulerAndActions(rootLayer, OPERATE_TYPE_PAUSE, IGNORE_TAG);

4，恢复

GamePauseUtils::getInstance()->operateAllSchedulerAndActions(rootLayer, OPERATE_TYPE_RESUME, IGNORE_TAG);

特点：适合所有情况，值需要把不需要暂停的节点用Tag标志即可。

<方法2>

Director::getInstance()->pause() 

特点：不常用，因为会关闭掉渲染。不友好。

<方法3>onExit与onEnter

class SecondScene : public Layer
{
public:
static cocos2d::Scene* createScene();
static Layer* createLayer(Node* pauseNode);
virtual bool init();
void menuCloseCallback1(cocos2d::Ref* pSender);
CREATE_FUNC(SecondScene);
Node* _pauseNode;

};

暂停

this->onExit();
Director::getInstance()->getRunningScene()->addChild(SecondScene::createLayer(this));

恢复

Layer* SecondScene::createLayer(Node* pauseNode)
{

auto layer = SecondScene::create();
layer->_pauseNode = pauseNode;
return layer;
}

bool SecondScene::init()
{
if (!Layer::init()){
return false;
}

Size visibleSize = Director::getInstance()->getVisibleSize();
Vec2 origin = Director::getInstance()->getVisibleOrigin();

auto closeItem = MenuItemImage::create(
"CloseNormal.png",
"CloseSelected.png",
CC_CALLBACK_1(SecondScene::menuCloseCallback1, this));

closeItem->setPosition(Vec2(visibleSize.width/2, visibleSize.height/2));
auto menu = Menu::create(closeItem, NULL);
menu->setPosition(Vec2::ZERO);
this->addChild(menu, 1);

return true;
}

void SecondScene::menuCloseCallback1(Ref* pSender){
this->_pauseNode->onEnter();
this->removeFromParent();
}

特点：同方法1，只是看起来更优雅一点
<方法4>pushScene与popScene
暂停

auto scene = SecondScene::createScene();
Director::getInstance()->pushScene(scene);

Scene* SecondScene::createScene()
{
auto scene = Scene::create();
auto layer = SecondScene::create();
scene->addChild(layer);
return scene;
}

恢复

Director::getInstance()->popScene();

特点：这种暂停其实是，新建了一个场景。覆盖到上面。

<方法5>推荐,大海战中用的

暂停

function NewBattleUILayer:onPauseGameClick( sender, eventType )
if eventType == ccui.TouchEventType.ended then
GameScene.CurGameScene:pauseActionAndSchedule( true )
cc.Director:getInstance():getRunningScene():addChild( BattlePauseLayer:create(), 777777 )
end
end
恢复

function BattlePauseLayer:_soundStatusWriteFile()
GameScene.CurGameScene:resumeActionAndSchedule()

cc.UserDefault:getInstance():setBoolForKey( "isMusicClose", self.isMusicClose )
cc.UserDefault:getInstance():flush()
cc.UserDefault:getInstance():setBoolForKey( "isEffectClose", self.isEffectClose )
cc.UserDefault:getInstance():flush()

self:removeFromParent()
end
