ScriptedImporter.OnImportAsset

切换到手册
public void OnImportAsset (Experimental.AssetImporters.AssetImportContext ctx);

参数

ctx 此参数包含处理导入事件所需的所有上下文信息,自定义导入器也用它来存储生成的 Unity 资源。

描述

此方法必须由派生类重写,并由资源管线调用来导入文件。

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); } }
