Create samples for packages

Starting with Unity Editor version 2019.1, you can add samples to a package. A sample might be a piece of example code, some shadersA program that runs on the GPU. More info
See in Glossary and textures, some animation, or any other files that you can usually find under the project’s Assets folder.

When you open the Package Manager window and select a package containing samples, an Import button appears in the package’s details panel for each sample in the package. When you select Import, the Package Manager copies the whole subfolder structure for that sample under the project’s Assets folder.

To add samples to your package:

1. Put the asset files or example C# code files under the Samples~ folder. You can have more than one sample in a package; each subfolder of the Samples~ folder has one sample.

   Note: The tilde character (~) tells Unity to ignore the contents the Samples~ folder. Such folders aren’t tracked with .meta files.

2. Add a JSON object for each sample under the samples array in your package.json manifest file.

Location of sample files

You can add your sample assets under subfolders of the Samples~ folder of your package. For example, a package with shader samples might look something like this:

MyPackage
  ├── package.json
  └── Samples~
        ├── SamplesHDRP
        │    ├── Textures
        │    |     ├── MossyRock.bmp
        │    |     └── SandyRock.bmp
        │    └── Shader
        │          ├── Lit Texture Blend HDRP.ShaderGraph
        │          └── Lit Vertex Color HDRP.ShaderGraph
        └── SamplesStandard
        │    ├── Textures
        │    |     ├── MossyRock.bmp
        │    |     └── SandyRock.bmp
        │    └── Shader
        │          ├── StandardTextureBlend.shader
        │          └── StandardVertexColor.shader
        └── SamplesUniversalRP
             ├── Textures
             |     ├── MossyRock.bmp
             |     └── SandyRock.bmp
             └── Shader
                   ├── Lit Texture Blend URP.ShaderGraph
                   └── Lit Vertex Color URP.ShaderGraph

Include your samples in the manifest

Add a JSON array called samples to the package.json file. For each sample, add a JSON object containing at least the displayName and the path to the samples folder:

For example, using the same structure as the example for Location of sample files, the samples section looks similar to this:

{
    "samples": [
        {
            "displayName": "HDRP Shaders",
            "description": "Contains sample shaders for the High Definition render pipeline",
            "path": "Samples~/SamplesHDRP"
        },
        {
            "displayName": "URP Shaders",
            "description": "Contains sample shaders for the Universal render pipeline",
            "path": "Samples~/SamplesUniversalRP"
        },
        {
            "displayName": "Standard RP Shaders",
            "description": "Contains sample shaders for the Standard render pipeline",
            "path": "Samples~/SamplesStandard"
        }
    ]
}
