基于鼠标位置的Animate艺术线条

时间:2017-05-20 18:41:31

标签: javascript jquery animation mouse-position

我有一个在插画家中创建的头骨线条。我试图根据鼠标位置填充或擦除线条。似乎有两种方法可以实现这一目标:

  1. 使用懒线画家画出我在jsfiddle中看到的线条 - http://jsfiddle.net/mwmksa62/然后根据鼠标的y位置找到一种方法来进行动画修复(这样头骨完全绘制在视口的顶部,并且在我的鼠标位于底部时开始。

  2. 为我需要的动画制作并创建一个gif,让gif根据鼠标的y位置播放动画(当鼠标位于视口顶部时,动画最终帧显示)

  3. 作为一个对Javascript全新的人,我喜欢在这里朝着正确的方向努力!
