Description

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.

using UnityEngine;
using UnityEditor.Experimental.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 a GameObject and will be automatically converted into a Prefab // (Only the 'Main Asset' is elligible 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); } }
