ScriptedImporter

설명

Abstract base class for custom Asset importers.

Scripted importers are scripts that are associated with specific file extensions. They are invoked by Unity's Asset pipeline to convert the contents of associated files into Assets.

Use the ScriptedImporterAttribute class to register custom importers with the Asset pipeline.

The C# fields of a ScriptedImporter are serialized, exactly like fields on a MonoBehaviour. See Script Serialization for details. You can see these properties in the Inspector and use them to control the behaviour of the importer for each asset. To programmatically access the value of an asset's properties, use AssetImporter.GetAtPath and type cast the return value to the correct class derived from ScriptedImporter. After changing values, trigger a fresh import by calling EditorUtility.SetDirty and then AssetImporter.SaveAndReimport.

using UnityEngine;
using UnityEditor.AssetImporters;
using System.IO;

[ScriptedImporter(1, "cube")]
public class CubeImporter : ScriptedImporter
{
    public float m_Scale = 1;

    public override void OnImportAsset(AssetImportContext ctx)
    {
        var cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
        var position = JsonUtility.FromJson<Vector3>(File.ReadAllText(ctx.assetPath));

        cube.transform.position = position;
        cube.transform.localScale = new Vector3(m_Scale, m_Scale, m_Scale);

        // 'cube' is a GameObject and will be automatically converted into a Prefab
        // (Only the 'Main Asset' is eligible to become a Prefab.)
        ctx.AddObjectToAsset("main obj", cube);
        ctx.SetMainObject(cube);

        var material = new Material(Shader.Find("Standard"));
        material.color = Color.red;

        // Assets must be assigned a unique identifier string consistent across imports
        ctx.AddObjectToAsset("my Material", material);

        // Assets that are not passed into the context as import outputs must be destroyed
        var tempMesh = new Mesh();
        DestroyImmediate(tempMesh);
    }
}
