有什么办法能让它的y轴的时候也脱离吗,或者像你那样把它限制在一个范围,只想到单轴向的思路,看了我对功能的理解还是不够透彻

Very nice! 👍️ 4.3 setups can seem like magic the first time you see them!

You can probably use 2 sliders, one for X and one for Y, with additive set. 🤔

    Nate 好的!非常感谢您的解答!

    Nate 在休假中、没有关注新特性。(停留在4.3.16)
    研究了一下大概是这个样子?
    不清楚是那个版本新添加的滑块约束动画帧可以映射到某个骨骼的变换属性上。

    新功能能实现很多有趣的想法。但是好像变得更加复杂了(指理解和学习成本)
    很多时候理解原理但是可能习惯直接键帧似乎、、

      Looks like you got it! For everyone else: a slider animation controls the IK mix. When the slider's bone enters the range, the IK is turned on, when it leaves the range it is turned off.

      These setups are definitely more complex than just setting keys. Mostly we are just exploring the new tools. In the real world you would have some goal, then hopefully you use the advanced setups only when warranted. We see far too many projects that have literally 500 or even 1000 constraints, and that's before sliders and the new transform constraint. Please don't do that! 🙏

      If you've missed the last few updates, check the changelog. The update today was very important, I posted about it here:

      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!

        Voice-of-Shadow WHAT?! Did you create constraint by dragging and releasing a bone on another?

          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. 😬

            Voice-of-Shadow
            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、、、

                真如Nate所说的、我使用热键快捷创建约束。
                等正式版的时候、我可能需要重新优化我的热键排布、因为多了很多功能

                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!
