unity-game-engine - Unity3D 第三人称 Controller 和动画

Question

我的问题是，我在Unity3D的第三人称 Controller 中设置的自定义行走动画没有显示。

动画是从具有 model@walk.fbx 结构的 FBX 文件导入的。我知道动画有效，因为如果我将它用作它显示的空闲动画。另一方面，这似乎也不是 Controller 脚本的问题，因为它与原型(prototype)角色配合得很好。

似乎正在播放的动画是在动画组件中选择的动画(已选择“自动播放”)。任何从第三人称 Controller 更改动画的尝试都适用于原型(prototype)角色，但不适用于我的角色。

我没有也不想要运行和跳跃动画。对于原型(prototype)角色，我为每个角色设置了行走动画，没有产生任何不利影响。 Controller 不会以这种方式关闭动画，因为控制台中没有来自第三人称 Controller 脚本的日志条目。与 CrossFade 调用相关的线路正在被调用。

有什么线索可以告诉我下一步可以去哪里吗？更有可能是 Controller 问题还是动画问题？完全是别的东西吗？

更新:下面是我的 Controller 的代码。当我使用 Unity 提供的建筑 worker 示例模型时，效果很好。带有 _animation.CrossFade 的行将在预期时间被调用。使用 Play 或 Blend 没有帮助。控制台中没有记录任何错误。

对于我们的自定义动画，它不起作用。我现在怀疑问题出在模型上。不幸的是，我无权分享该模型的示例。我已向动画师询问有关他如何创建 FBX 导出的更多详细信息。为了使模型在 Unity 中工作，他需要使用任何特定设置吗？但奇怪的是，如果我将它们独立地添加到场景中，动画确实可以工作。

更新 2: 用于创建动画的设置位于这些屏幕截图中。它们正确吗？

Answer 1

(还:-)没有答案，但我需要更多的空间和图像。

自 Unity3d 3.5 以来，处理基于animation@model.fbx 表示法的导入的方式已经改变，并且有些人报告了问题(例如 BIG Unity 3.5.0f1 problem with Skinned Rig - Major FAIL )。当第二个根骨骼开始播放时就会出现问题，但我可以通过将动画拖动到模型文件预制件来解决这个问题(我的大部分动画都包含在模型中，其余的 2 个动画也没什么大问题)。

为了确保我正确理解您在评论部分的回答，您有这样的内容:

这意味着:

• 在角色模型中，动画数组包含所有动画
• 骨骼的数量和所有名称都与原型(prototype)角色中的完全相同
• 如果打开动画 View ，您可以看到在层次结构 View 中所选角色的所有动画的只读列表

假设这没问题，还有一些建议:

• 我在代码中看不到您设置 WrapMode.Loop 的任何地方或动画速度。您确定它在检查器中配置为循环并且没有在某处被覆盖吗？
• 不带参数的 CrossFade 假定为 0.3 秒
• 交叉淡入淡出调用后会发生什么？ DefaultTake 是否停止播放？
• 可以拖动默认行走动画
• 您使用不同的动画层吗？
• 设置Debug.Log ("Walk: "+ player.animation.IsPlaying ("Walk")); 时会得到什么输出

<小时/>

[更新]

1. 让我们看看导入设置。你有分割动画检查过，开始处是否可能输入了错误的值以及结束就像1-1？

   

2. 关于切换 IsPlaying:请创建更多有关 AnimationState 的输出特性。最值得注意的速度、长度、启用、重量……我怀疑动画太短或播放太快。
3. 没有骨骼动画的行走动画听起来有点奇怪。另一方面，如果骨骼名称不匹配，控制台会大声喊叫。所以我认为现在没有问题。
