在上节的基础上,看看怎么实现场景的切换。
添加一个场景WelcomeScene
[cpp]
#include "WelcomeScene.h"
#include "GameScene.h"
using namespace cocos2d;
CCScene* WelcomeScene::scene()
{
CCScene * scene = NULL;
do
{
scene=CCScene::create();
WelcomeScene* gameScene=WelcomeScene::create();
scene->addChild(gameScene);
}while(0);
return scene;
}
bool WelcomeScene::init()
{
this->setTouchEnabled(true);
bool bRet = false;
do
{
CCSprite* pMap = CCSprite::create("welcome_bg.png");
CCSize size = CCDirector::sharedDirector()->getWinSize();
pMap->setPosition(ccp(size.width/2, size.height/2));
this->addChild(pMap, 0);
CCMenuItemImage *pCloseItem = CCMenuItemImage::create(
"StartGameNormal.png",
"StartGamePressed.png",
this,
menu_selector(WelcomeScene::menuStartCallback));
CCMenu* pMenu = CCMenu::create(pCloseItem, NULL);
pMenu->setPosition(size.width/2,size.height/2);
this->addChild(pMenu, 1);
}while(0);
bRet=true;
return bRet;
}
void WelcomeScene::menuStartCallback(CCObject* pSender)
{
CCScene * scene=GameScene::scene();
CCDirector::sharedDirector()->replaceScene(scene);
}
在menuStartCallback()中通过导演来切换场景。
使用特效:
[cpp]
CCDirector::sharedDirector()->replaceScene((CCTransitionSlideInR::create(1, scene)));
网上找的特效:
CCTransitionJumpZoom::transitionWithDuration(t, s);//跳跃式,本场景先会缩小,然后跳跃进来
CCTransitionFade::transitionWithDuration(t, s);//淡出淡入,原场景淡出,新场景淡入
CCTransitionFade::transitionWithDuration(t, s, ccWHITE);//如果上一个的函数,带3个参数,则第三个参数就是淡出淡入的颜色
CCTransitionFlipX::transitionWithDuration(t, s, kOrientationLeftOver);//x轴左翻
CCTransitionFlipX::transitionWithDuration(t, s, kOrientationRightOver);//x轴右翻
CCTransitionFlipY::transitionWithDuration(t, s, kOrientationUpOver);//y轴上翻
CCTransitionFlipY::transitionWithDuration(t, s, kOrientationDownOver);//y轴下翻
CCTransitionFlipAngular::transitionWithDuration(t, s, kOrientationLeftOver);//有角度转的左翻
CCTransitionFlipAngular::transitionWithDuration(t, s, kOrientationRightOver);//有角度转的右翻
CCTransitionZoomFlipX::transitionWithDuration(t, s, kOrientationLeftOver);//带缩放效果x轴左翻
CCTransitionZoomFlipX::transitionWithDuration(t, s, kOrientationRightOver);//带缩放效果x轴右翻
CCTransitionZoomFlipY::transitionWithDuration(t, s, kOrientationUpOver);//带缩放效果y轴上翻
CCTransitionZoomFlipY::transitionWithDuration(t, s, kOrientationDownOver);//带缩放效果y轴下翻
CCTransitionZoomFlipAngular::transitionWithDuration(t, s, kOrientationLeftOver);//带缩放效果/有角度转的左翻
CCTransitionZoomFlipAngular::transitionWithDuration(t, s, kOrientationRightOver);//带缩放效果有角度转的右翻
CCTransitionShrinkGrow::transitionWithDuration(t, s);//交错换
CCTransitionRotoZoom::transitionWithDuration(t, s);//转角换
CCTransitionMoveInL::transitionWithDuration(t, s);//新场景从左移入覆盖
CCTransitionMoveInR::transitionWithDuration(t, s);//新场景从右移入覆盖
CCTransitionMoveInT::transitionWithDuration(t, s);//新场景从上移入覆盖
CCTransitionMoveInB::transitionWithDuration(t, s);//新场景从下移入覆盖
CCTransitionSlideInL::transitionWithDuration(t, s);//场景从左移入推出原场景
CCTransitionSlideInR::transitionWithDuration(t, s);//场景从右移入推出原场景
CCTransitionSlideInT::transitionWithDuration(t, s);//场景从上移入推出原场景
CCTransitionSlideInB::transitionWithDuration(t, s);//场景从下移入推出原场景
以下三个需要检测opengl版本是否支持CCConfiguration::sharedConfiguration()->getGlesVersion() <= GLES_VER_1_0如果为真则为不支持
CCTransitionCrossFade::transitionWithDuration(t,s);//淡出淡入交叉,同时进行
CCTransitionRadialCCW::transitionWithDuration(t,s);//顺时针切入
CCTransitionRadialCW::transitionWithDuration(t,s);//逆时针切入
以下两个需要先设置摄像机,使用CCDirector::sharedDirector()->setDepthTest(true);
CCTransitionPageTurn::transitionWithDuration(t, s, false);//翻页,前翻
CCTransitionPageTurn::transitionWithDuration(t, s, true);//翻页,后翻
CCTransitionFadeTR::transitionWithDuration(t, s);//向右上波浪
CCTransitionFadeBL::transitionWithDuration(t, s);//向左下波浪
CCTransitionFadeUp::transitionWithDuration(t, s);//向上百叶窗
CCTransitionFadeDown::transitionWithDuration(t, s);//向下百叶窗
CCTransitionTurnOffTiles::transitionWithDuration(t, s);//随机小方块
CCTransitionSplitRows::transitionWithDuration(t, s);//按行切
CCTransitionSplitCols::transitionWithDuration(t, s);//按列切
