cocos2dx 动画 二（iOS）

7.Bezier曲线

需要ccBezierConfig结构体，设置2个控制点和一个结束点

 ccBezierConfig bc;
 bc.controlPoint_1 = Vec2(,);
 bc.controlPoint_2 = Vec2(,);
 bc.endPosition = Vec2(,);

 BezierTo *bz = BezierTo::create(2.0, bc);

 spt->runAction(bz);

8.控制动画速度变化

EaseSineIn由慢到快

EaseSineOut由快到慢 刹车效果

EaseSineInOut由慢到快再到慢

以MoveTo匀速为例 用EaseSineIn包装

 MoveTo *to = MoveTo::create(, Vec2(,));
 EaseSineIn *in = EaseSineIn::create(to);
 spt->runAction(in);

9.闪烁动画

第一参数：时间

第二参数：次数

 Blink *bl = Blink::create(, );
 spt->runAction(bl);

10.Sequence （动画序列，精灵需要顺序执行不同动画）

 MoveTo *mt = MoveTo::create(, Vec2(,));
 DelayTime *dt = DelayTime::create();
 Blink *bl = Blink::create(, );
 Sequence *sq = Sequence::create(mt,dt,bl, NULL);
 spt->runAction(sq);

11.进度条动画

         Sprite *sp1 = Sprite::create("dark.jpg");
         sp1->setPosition(Vec2(,));
         this->addChild(sp1);

         Sprite *sp2 = Sprite::create("light.jpg");

         ProgressTimer *timer = ProgressTimer::create(sp2);
         timer->setPosition(Vec2(,));
         this->addChild(timer);

         timer->setType(ProgressTimer::Type::BAR);
         timer->setMidpoint(Vec2(, ));
         timer->setBarChangeRate(Vec2(,));

         ProgressTo *pt = ProgressTo::create(, );
         timer->runAction(pt);

12.并行动画(多个动画并发执行)

         Sprite *sp1 = Sprite::create("pean.jpg");
         sp1->setPosition(Vec2(,));
         this->addChild(sp1);

         MoveTo *mv = MoveTo::create(, Vec2(,));
         RotateBy *rb = RotateBy::create(, );

         Spawn *sp = Spawn::create(mv,rb, NULL);

         sp1->runAction(sp);

最后一个：CallFunc (回调)

         Sprite *sp1 = Sprite::create("pean.jpg");
         sp1->setPosition(Vec2(,));
         this->addChild(sp1);

         MoveTo *mv = MoveTo::create(, Vec2(,));
         RotateBy *rb = RotateBy::create(, );

         Spawn *sp = Spawn::create(mv,rb, NULL);

         CallFunc *cf = CallFunc::create([&](void)
                                         {
                                             CCLOG("动画完");
                                         });
         Sequence *sq = Sequence::create(sp,cf, NULL);
         sp1->runAction(sq);
