cocos2dx 动画 一

1.精灵的runAction方法

    spt = Sprite::create("pean.jpg");
    this->addChild(spt);
    
    MenuItemFont *item = MenuItemFont::create("开始", [&](Ref* spen){
        ToggleVisibility *visi = ToggleVisibility::create();
        spt->runAction(visi);
    });
    Menu *menu = Menu::create(item, NULL);
    menu->setPosition(100, 500);
    this->addChild(menu);

2.FadeTo方法

FadeTo *fade = FadeTo::create(2.0, 0);
spt->runAction(fade);

3.MoveTo方法

MoveTo *move = MoveTo::create(2, ccp(500,500));
spt->runAction(move);

4.MoveBy方法（x/y轴偏移量）

MoveBy *move = MoveBy::create(2.0, Vec2(100, 100));
spt->runAction(move);

5.JumpBy

第一个参数：跳跃总时间

第二个参数：跳跃后的偏移位置

第三个参数：跳跃的高度

第四个参数：跳跃的次数

JumpBy *by = JumpBy::create(2.0, Vec2(200,0), 300, 1);
spt->runAction(by);

6.CardinalSplineBy(按轨迹移动)

貌似 CardinalSplineBy 和CardinalSplineTo一样，用的是点不是偏移量

PointArray *pa = PointArray::create(5);
pa->addControlPoint(Vec2(200,0));
pa->addControlPoint(Vec2(200,200));
pa->addControlPoint(Vec2(400,200));
pa->addControlPoint(Vec2(400,0));
CardinalSplineBy *sb = CardinalSplineBy::create(5.0, pa, 1);
spt->runAction(sb);
