cpp-tests ActionsEaseTest

～～～～我的生活，我的点点滴滴！！

Action的动作实在太多太多了，有40-50种，自由组合等能出的更多，这里没有全部列下来，只是简单的列了下面几种。

更详细的讲解请看 http://blog.csdn.net/ac_huang/article/details/37972017

1、简单的快慢移动效果

void SpriteEase::onEnter(){    EaseSpriteDemo::onEnter();    //创建一个相对移动，即在3s内，x轴移动VisibleRect::right().x-130，y轴移动0    auto move = MoveBy::create(3, Vec2(VisibleRect::right().x-130,0));//最快捷的反向运动，move动作的反向动作，即移动到位后，在原路返回    auto move_back = move->reverse();    // EaseIn 由慢至快。    auto move_ease_in = EaseIn::create(move->clone(), 2.5f);    auto move_ease_in_back = move_ease_in->reverse();    // EaseOut 由快至慢。    auto move_ease_out = EaseOut::create(move->clone(), 2.5f);    auto move_ease_out_back = move_ease_out->reverse();        auto delay = DelayTime::create(0.25f);    //注意看第二个参数为delay与第四个为delay->clone()，后面全是他的复制品,仔细看源码，他里面有一个//保存此对象(delay)的动作，即赋值。如果不使用clone，那么全是一个对象指针，后续操作会全乱。//delay->clone()为深度复制，即不是简单的改变指针指向，复制他的一切(包括动作、形为、监听等)//下面这个动作组是：移动----等待----返回    auto seq1 = Sequence::create(move, delay, move_back, delay->clone(), nullptr);    auto seq2 = Sequence::create(move_ease_in, delay->clone(), move_ease_in_back, delay->clone(), nullptr);    auto seq3 = Sequence::create(move_ease_out, delay->clone(), move_ease_out_back, delay->clone(), nullptr);        //RepeatForever永久运动，但是后面使用stopAction来停止    auto a2 = _grossini->runAction(RepeatForever::create(seq1));    a2->setTag(1);    auto a1 = _tamara->runAction(RepeatForever::create(seq2));    a1->setTag(1);    auto a = _kathia->runAction(RepeatForever::create(seq3));    a->setTag(1);//用来停止上面三个精灵的移动    schedule(schedule_selector(SpriteEase::testStopAction), 6.25f);}void SpriteEase::testStopAction(float dt){//停止    unschedule(schedule_selector(SpriteEase::testStopAction));    _tamara->stopActionByTag(1);    _kathia->stopActionByTag(1);    _grossini->stopActionByTag(1);}

看上面的注释，为了帮助我记录笔记和一点点学习源码打开入口。

2、带有弹性的移动

void SpriteEaseElastic::onEnter(){    EaseSpriteDemo::onEnter();        auto move = MoveBy::create(3, Vec2(VisibleRect::right().x-130, 0));    auto move_back = move->reverse();    //让目标动作赋予弹性 ，且以目标动作起点位子赋予弹性    auto move_ease_in = EaseElasticIn::create(move->clone() );    auto move_ease_in_back = move_ease_in->reverse();    //让目标动作赋予弹性 ，且以目标动作终点位子赋予弹性    auto move_ease_out = EaseElasticOut::create(move->clone() );    auto move_ease_out_back = move_ease_out->reverse();        auto delay = DelayTime::create(0.25f);    auto seq1 = Sequence::create(move, delay, move_back, delay->clone(), nullptr);    auto seq2 = Sequence::create(move_ease_in, delay->clone(), move_ease_in_back, delay->clone(), nullptr);    auto seq3 = Sequence::create(move_ease_out, delay->clone(), move_ease_out_back, delay->clone(), nullptr);        _grossini->runAction( RepeatForever::create(seq1));    _tamara->runAction( RepeatForever::create(seq2));    _kathia->runAction( RepeatForever::create(seq3));    }

让物体开始移动和结束移动时有一点点抖动，看起来像有弹性一样。

3、带有反弹的物体运动

void SpriteEaseElasticInOut::onEnter(){    EaseSpriteDemo::onEnter();        auto move = MoveBy::create(3, Vec2(VisibleRect::right().x-130, 0));//让目标动作赋予弹性 ，且以目标动作起点和终点位子赋予弹性    auto move_ease_inout1 = EaseElasticInOut::create(move->clone(), 0.3f);    auto move_ease_inout_back1 = move_ease_inout1->reverse();    //让目标动作赋予弹性 ，且以目标动作起点和终点位子赋予弹性    auto move_ease_inout2 = EaseElasticInOut::create(move->clone(), 0.45f);    auto move_ease_inout_back2 = move_ease_inout2->reverse();        auto move_ease_inout3 = EaseElasticInOut::create(move->clone(), 0.6f);    auto move_ease_inout_back3 = move_ease_inout3->reverse();        auto delay = DelayTime::create(0.25f);            auto seq1 = Sequence::create(move_ease_inout1, delay, move_ease_inout_back1, delay->clone(), nullptr);    auto seq2 = Sequence::create(move_ease_inout2, delay->clone(), move_ease_inout_back2, delay->clone(), nullptr);    auto seq3 = Sequence::create(move_ease_inout3, delay->clone(), move_ease_inout_back3, delay->clone(), nullptr);        _tamara->runAction( RepeatForever::create(seq1));    _kathia->runAction( RepeatForever::create(seq2));    _grossini->runAction( RepeatForever::create(seq3)); }void SpriteEaseBounce::onEnter(){    EaseSpriteDemo::onEnter();        auto move = MoveBy::create(3, Vec2(VisibleRect::right().x-130, 0));    auto move_back = move->reverse();    //让目标动作赋予反弹力，且以目标动作开始位子开始反弹    auto move_ease_in = EaseBounceIn::create(move->clone() );    auto move_ease_in_back = move_ease_in->reverse();    //让目标动作赋予反弹力，且以目标动作结束位子开始反弹    auto move_ease_out = EaseBounceOut::create(move->clone() );    auto move_ease_out_back = move_ease_out->reverse();        auto delay = DelayTime::create(0.25f);        auto seq1 = Sequence::create(move, delay, move_back, delay->clone(), nullptr);    auto seq2 = Sequence::create(move_ease_in, delay->clone(), move_ease_in_back, delay->clone(), nullptr);    auto seq3 = Sequence::create(move_ease_out, delay->clone(), move_ease_out_back, delay->clone(), nullptr);        _grossini->runAction( RepeatForever::create(seq1));    _tamara->runAction( RepeatForever::create(seq2));    _kathia->runAction( RepeatForever::create(seq3));    }void SpriteEaseBounceInOut::onEnter(){    EaseSpriteDemo::onEnter();    auto move = MoveBy::create(3, Vec2(VisibleRect::right().x-130, 0));    auto move_back = move->reverse();    //让目标动作赋予反弹力，且以目标动作结束位子开始反弹    auto move_ease = EaseBounceInOut::create(move->clone() );    auto move_ease_back = move_ease->reverse();        auto delay = DelayTime::create(0.25f);        auto seq1 = Sequence::create(move, delay, move_back, delay->clone(), nullptr);    auto seq2 = Sequence::create(move_ease, delay->clone(), move_ease_back, delay->clone(), nullptr);        this->positionForTwo();        _grossini->runAction( RepeatForever::create(seq1));    _tamara->runAction( RepeatForever::create(seq2));}

这个要和上面的弹性区别，这个看起来像有一个无形的墙把物体反弹回来，从上面可以看出来，大体分为开始就反弹，结束时反

弹，或者开始与结束时都反弹。
