大多数社交游戏(如 CastleVille (c) Zynga 或 Magic Land (c) Wooga)都有硬币、星星等奖励给玩家一些简单的动作,比如砍树。
doobers 似乎执行了几个补间:
- 首先,他们扑通一声跳了出来。它们的尺寸也会反弹。
- 之后,他们以贝塞尔曲线飞到得分栏。
我为我的问题准备了一个非常简单的测试用例和屏幕截图。测试用例在 Flex 中,因为这是我最近一直在使用的,但我的问题更笼统(ActionScript,Tween)。我正在使用com.greensock.TweenMax库。
我的问题:我已经弄清楚如何做第二个贝塞尔部分。但我不知道,第一个弹跳部分怎么做?

另外我想知道,如何在最后添加“宝丽来相机闪光灯”效果?
更新:
在 LondonDrugs_MediaServices 的帮助下(谢谢!)doobers 现在挤压和跳跃(代码如下),但我仍然有 3 个未解决的问题:
- 如何在鼠标悬停事件上运行 flyTween?
- 如何在最后添加“宝丽来闪电战”补间?
- 不知道如何在最后删除鼠标悬停处理程序 - 因为它是一个匿名闭包
我还在GreenSock 论坛上发布了我的问题。
谢谢你的任何提示

UPDATE2:谢谢LondonDrugs_MediaServices,这里再次更新了截图+代码。
和 doobers 一起玩已经很有趣了,但是仍然有 2 个小问题:
- 我真的必须杀死(延迟的)补间蝇吗?我不能在鼠标悬停时以某种方式修改它的延迟(将其设置为 0)吗?
- 最后有那种“相机闪光”效果会很好。我只是不记得它是如何完成的——一些标准的 Flash MX 效果......
