| About Animation C# Jobs Samples | ||
| =============================== | ||
|
|
||
| The Animation C# Jobs Samples package includes examples of Playable graphs | ||
| using Animation C# Jobs. For more information, see | ||
| [AnimationScriptPlayable](https://docs.unity3d.com/ScriptReference/Experimental.Animations.AnimationScriptPlayable.html). | ||
|
|
||
| Installing Animation C# Jobs Samples | ||
| ==================================== | ||
|
|
||
| To install this package, follow the instructions in the | ||
| [Package Manager documentation](https://docs.unity3d.com/Packages/com.unity.package-manager-ui@latest/index.html). | ||
|
|
||
| Using Animation C# Jobs Samples | ||
| =============================== | ||
|
|
||
| Because package content is read-only, it is not possible to open scenes | ||
| directly from a package directory, but it is possible to copy the scene files | ||
| locally, in the `Assets` folder. | ||
|
|
||
| To do so, go to `Packages/Animation C# Jobs Samples/Samples/Scenes`, then | ||
| select the sample scenes you want to try, and copy them into your `Assets` | ||
| folder. | ||
|
|
||
| Once copied, go to your `Assets` folder and open the Unity scene that you would | ||
| like to test. | ||
|
|
||
| Samples | ||
| ------- | ||
|
|
||
| ### SimpleMixer | ||
|
|
||
| This sample shows how to mix two clips together on a generic character. | ||
|
|
||
| ### WeightedMaskMixer | ||
|
|
||
| This sample is based on the SimpleMixer, but you can change the weights of some | ||
| joints (left arm, right arm, and head), so that the second clip only applies | ||
| based on the joint weights. | ||
|
|
||
| ### LookAt | ||
|
|
||
| This sample adds a look-at behaviour on a Chomper, a quadruped creature from the | ||
| [3D Game Kit](https://assetstore.unity.com/packages/essentials/tutorial-projects/3d-game-kit-115747). | ||
|
|
||
| ### TwoBoneIK | ||
|
|
||
| This sample adds a two-bone IK on a generic human character. | ||
|
|
||
| ### FullBodyIK | ||
|
|
||
| This sample create a fullbody IK on a humanoid character. | ||
|
|
||
| Technical details | ||
| ================= | ||
|
|
||
| Requirements | ||
| ------------ | ||
|
|
||
| This version of Animation C# Jobs Samples is compatible with Unity 2018.2 and | ||
| later. | ||
|
|
||
| The [GraphVisualizer](https://github.com/Unity-Technologies/graph-visualizer) | ||
| can be used to have a visual representation of the graphs in the samples. | ||
|
|
||
| Package contents | ||
| ---------------- | ||
|
|
||
| The following table indicates the structure of the package: | ||
|
|
||
| | Location | Description | | ||
| |---------------------------|-----------------------------------------------------------------------------------------------| | ||
| | `Resources` | Contains all the resources that the samples need (e.g. meshes, textures, animations, ...). | | ||
| | `Runtime/AnimationJobs` | Contains all the animation C# jobs. | | ||
| | `Samples/Scenes` | Contains all the sample scenes. | | ||
| | `Samples/Scripts` | Contains all the sample scripts. | | ||
|
|
||
| Document revision history | ||
| ------------------------- | ||
|
|
||
| | Date | Reason | | ||
| |---------------|---------------------------------------| | ||
| | June 01, 2018 | New way of testing the samples. | | ||
| | May 30, 2018 | First public release: 0.5.0-preview. | | ||
| | May 07, 2018 | Creation of the package. | |
