第三阶段：常用功能2

1.Cocos2d-x场景切换

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

Sprite *bg = Sprite::create( "bg.jpg" );
bg->setPosition(visibleSize.width/ 2 ,visibleSize.height/ 2 );
addChild(bg);

LabelTTF *label = LabelTTF::create( "Show Next Scene" , "Courier" , 36 );
addChild(label);

label->setPosition(visibleSize.width/ 2 );

EventListenerTouchOneByOne *listener = EventListenerTouchOneByOne::create();
listener->onTouchBegan = [label, this ](Touch* t,Event *e){

if (label->getBoundingBox().containsPoint(t->getLocation())) {

Director::getInstance()->replaceScene(TransitionFadeBL::create( 1 ,ImageScene::createScene()));
}

return false ;
};
Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener,label);

return true;

在ImageScene.h中

#include <iostream>
#include <cocos2d.h>

USING_NS_CC;

class ImageScene: public Layer {

public :

static Scene* createScene();

virtual bool init();
CREATE_FUNC(ImageScene);
};

在ImageScene.cpp中

"ImageScene.h"

Scene* ImageScene::createScene(){

Scene* scene = Scene::create();
ImageScene * layer = ImageScene::create();

scene->addChild(layer);

return scene;

}

bool ImageScene ::init(){

Size size = Director::getInstance()->getVisibleSize();
Sprite *s = Sprite::create( "HelloWorld.png" );
s->setPosition(size.width/ 2 );

addChild(s);

true ;

}

2.Cocos2d-x场景切换效果

Director::getInstance()->replaceScene(TransitionFadeBL::create( 1 ,ImageScene::createScene()));

cocos2d Scene场景转换

TransitionCrossFade.create(t,scene)//交叉消失两个场景使用cc.RenderTexture对象。
TransitionFad.create(t,scene,color)//淡出即将离任的场景,然后消失在传入的场景。
TransitionFadeBL.create(t,scene)//向左下波浪退出
TransitionFadeDown.create(t,0); background-color:inherit">//向下百叶窗式换场景
TransitionFadeUp.create(t,0); background-color:inherit">//向上百叶窗式换场景
TransitionJumpZoom.create(t,0); background-color:inherit">//跳跃式替换，场景缩小，再加载进来
TransitionMoveInB.create(t,0); background-color:inherit">//创建一个在底部，覆盖当前场景
TransitionMoveInR.create(t,0); background-color:inherit">//创建一个在右边，覆盖当前场景
TransitionMoveInT.create(t,0); background-color:inherit">//创建一个在左边，覆盖当前场景
TransitionPageTurn.create(t,backwards)//前翻页式场景替换
TransitionRadialCW.create(t,0); background-color:inherit">//逆时针切入
TransitionRotoZoom.create(t,0); background-color:inherit">//转换角度替换
TransitionFlipAngular.create(t,o)//按一定角度左翻
TransitionFlipX.create(t,0); background-color:inherit">//X轴左边翻换
TransitionFlipY.create(t,0); background-color:inherit">//Y轴左边翻换
TransitionZoomFlipAngular.create(t,0); background-color:inherit">//带有缩放效果，有角度的转左翻
TransitionZoomFlipX.create(t,0); background-color:inherit">//带有缩放效果，在X轴左翻
TransitionZoomFlipY.create(t,0); background-color:inherit">//带有缩放效果，左Y轴左翻
TransitionShrinkGrow.create(t,0); background-color:inherit">//交叉着替换场景
TransitionSlideInB.create(t,0); background-color:inherit">//场景有底部进入

3.Cocos2d-x动作

instant /'?nst(?)nt/ 片刻,顷刻,刹那/ 立即的

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

auto label = LabelTTF::create( "jikexueyuan" ,216)">30 );
label->setPosition(visibleSize.width/ 2 );
addChild(label);

auto listener = EventListenerTouchOneByOne::create();
listener->onTouchBegan = [label](Touch *t,162)">if (label->getBoundingBox().containsPoint(t->getLocation())) {

// label->runAction(MoveTo::create(1,Point(100,100)));
// label->runAction(MoveBy::create(1,Point(-50,-50))->reverse());

// label->runAction(Spawn::create(MoveBy::create(1,100)),RotateBy::create(1,360),NULL));

// label->runAction(Sequence::create(MoveBy::create(1,NULL));

label->runAction(Sequence::create(
MoveBy::create( 100 ,216)">100 )),
RotateBy::create( 360 ),
CallFunc::create([](){
MessageBox( "Action complete" ,27)">"complete" );
}),162)">NULL ));
}

false ;
};
Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener,label);

// label->runAction(Repeat::create(RotateBy::create(1,180),3));

// label->runAction(RepeatForever::create(RotateBy::create(1,180)))

true ;

4.Cocos2d-x动作反转

label->runAction(MoveBy::create(1,-50))->reverse());

5.Cocos2d-x动作重复

6.Cocos2d-x动作混合

同时执行：

8.Cocos2d-x动作侦听

RotateBy之后执行 CallFunc：

label->runAction(Sequence::create(
MoveBy::create( "complete" );

}),NULL));

9.Cocos2d-x动画

auto cache = SpriteFrameCache::getInstance();
cache->addSpriteFramesWithFile( "anim.plist" );

Vector<SpriteFrame*> vec;
char name[ 15 ];
memset(name,216)">0 ,216)">15 );

for ( int i= 0 ; i< 20 ; i++) {
sprintf(name,27)">"anim%04d" ,i);
vec.pushBack(cache->getSpriteFrameByName(name));

}

//每秒十帧

Animation *animation = Animation::createWithSpriteFrames(vec,216)">0.1f );
Animate *animate = Animate::create(animation);

auto sprite = Sprite::create();
addChild(sprite);
sprite->setPosition( 200 ,216)">200 );

sprite->runAction(RepeatForever::create(animate));
