你们想太复杂了、指针的阴影就是固定光源的情况、那么只需要做一个旋转就行了。
第二种方法需要关约束才能调整原始位置。
这里只是简单演示秒针阴影。
另外两个指针的映射就只是简单的60进制数学计算了。

官方的演示估计全绑定在那个"motor"驱动骨上

Voice-of-Shadow 啊明白了感谢感谢！

I think he used a hotkey, then clicked the target bone. Hotkeys are fast!

Nate 请问热键什么时候能变回之前的样子，能让常用的热键可以用在不同的面板

Soon! Sorry about that, just got busy with many things.

我感觉这个才是官方的做法，它x进出的时候才会完全吸附或者离开
你x离开的时候，y还附加在上面

yugutou you can also put the mix in a slider so it's softer. Also as for many things in Spine, there are multiple ways to achieve the same thing.
(I'm adding a small variation of the setup above with less bones so maybe it's easier to see the effect)

Erika 是的！你看我的层级树面板，我正是用你这种方法做出来的_{通过滑块，通过滑块约束去控制变换约束的混合}

yugutou
一个意思、滑块约束的动画分离XY键位置帧。
把滑块约束的动画变成约束的混合帧就行了。

其实实际生产中、还是直接K帧、、、

4.3.24-beta fixes that some types of timelines were not doing additive. For the "magnetic IK" now you can use 2 sliders with additive checked, allowing you to key the mixes for both and the mixes keyed at 0 will not affect the other slider (x + 0 = x). Additive is how you can have multiple animations and sliders affecting the same bones/constraints/etc.

基于Nate的演示、拓展了一下圆形范围。
可以基于变换曲线制作渐进。
目前不知道具体使用场景……

That's awesome! If you reverse the keys of the influence animation (so it goes from 100 influence to 0) it has a more natural movement as you leave/enter the circle range.
When you are in the centre of the circle it sticks close but loses it's stickiness softly as you leave the circle.

I can think of many uses for this in rigging!

Awesome examples!

Very nice! I worry a bit that the math will scare people.
