説明

Default editor for all asset importer settings.

Use the default editor to edit the import settings for assets. You can define a custom import settings editor for a specific asset type. To do this, create a new class that inherits from AssetImporterEditor and uses a CustomEditorAttribute that refers to a ScriptedImporter.

The following example shows how to make a custom ScriptedImporterEditor for a ScriptedImporter with a custom layout.

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

[CustomEditor(typeof(TransformImporter))] [CanEditMultipleObjects] public class TransformImporterEditor : ScriptedImporterEditor { // Stored SerializedProperty to draw in OnInspectorGUI. SerializedProperty m_GenerateChild;

public override void OnEnable() { base.OnEnable(); // Once in OnEnable, retrieve the serializedObject property and store it. m_GenerateChild = serializedObject.FindProperty("generateChild"); }

public override void OnInspectorGUI() { // Update the serializedObject in case it has been changed outside the Inspector. serializedObject.Update();

// Draw the boolean property. EditorGUILayout.PropertyField(m_GenerateChild);

// Apply the changes so Undo/Redo is working serializedObject.ApplyModifiedProperties();

// Call ApplyRevertGUI to show Apply and Revert buttons. ApplyRevertGUI(); } }

[ScriptedImporter(0, ".transform")] public class TransformImporter : ScriptedImporter { public bool generateChild;

public override void OnImportAsset(AssetImportContext ctx) { GameObject root = ObjectFactory.CreateGameObject(Path.GetFileNameWithoutExtension(ctx.assetPath)); if (generateChild) { GameObject child = ObjectFactory.CreateGameObject("child"); child.transform.SetParent(root.transform); } ctx.AddObjectToAsset("main", root); ctx.SetMainObject(root); } }

The following example demonstrates a specific case where the user cannot change settings and the Apply/Revert buttons are hidden with needsApplyRevert.

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

[CustomEditor(typeof(EmptinessImporter))] [CanEditMultipleObjects] public class EmptinessImporterEditor : ScriptedImporterEditor { //Let the parent class know that the Apply/Revert mechanism is skipped. protected override bool needsApplyRevert => false;

public override void OnInspectorGUI() { // Draw some information EditorGUILayout.HelpBox("Because this Importer doesn't have any settings, the Apply/Revert buttons are hidden.", MessageType.None); } }

[ScriptedImporter(0, ".emptiness")] public class EmptinessImporter : ScriptedImporter { public override void OnImportAsset(AssetImportContext ctx) { GameObject root = ObjectFactory.CreateGameObject(Path.GetFileNameWithoutExtension(ctx.assetPath)); ctx.AddObjectToAsset("main", root); ctx.SetMainObject(root); } }

The following example shows how to use extraDataType to read or save settings that are not part of the ScriptedImporter serialization, in the custom AssetImporterEditor.

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

[CustomEditor(typeof(BooleanImporter))] [CanEditMultipleObjects] public class BooleanImporterEditor : ScriptedImporterEditor { // Property to show in the custom OnInspectorGUI. SerializedProperty m_BooleanProperty;

// override extraDataType to return the type that will be used in the Editor. protected override Type extraDataType => typeof(BooleanClass);

// override InitializeExtraDataInstance to set up the data. protected override void InitializeExtraDataInstance(Object extraTarget, int targetIndex) { var boolean = (BooleanClass)extraTarget; // Read the boolean value from the text file and fill the extraTarget object with the data. string fileContent = File.ReadAllText(((AssetImporter)targets[targetIndex]).assetPath); if (!bool.TryParse(fileContent, out boolean.boolean)) { boolean.boolean = false; } }

protected override void Apply() { base.Apply(); // After the Importer is applied, rewrite the file with the custom value. for (int i = 0; i < targets.Length; i++) { string path = ((AssetImporter)targets[i]).assetPath; File.WriteAllText(path, ((BooleanClass)extraDataTargets[i]).boolean.ToString()); } }

public override void OnEnable() { base.OnEnable(); // In OnEnable, retrieve the importerUserSerializedObject property and store it. m_BooleanProperty = extraDataSerializedObject.FindProperty("boolean"); }

public override void OnInspectorGUI() { // Note: you don't need to call serializedObject.Update or serializedObject.ApplyModifiedProperties // because you are not changing the target (serializedObject) itself.

// Update the importerUserSerializedObject in case it has been changed outside the Inspector. extraDataSerializedObject.Update();

// Draw the boolean property. EditorGUILayout.PropertyField(m_BooleanProperty);

// Apply the changes so Undo/Redo is working. extraDataSerializedObject.ApplyModifiedProperties();

// Call ApplyRevertGUI to show Apply and Revert buttons. ApplyRevertGUI(); } }

public class BooleanClass : ScriptableObject { public bool boolean; }

[ScriptedImporter(0, ".boolean")] public class BooleanImporter : ScriptedImporter { public override void OnImportAsset(AssetImportContext ctx) { string fileContent = File.ReadAllText(ctx.assetPath); var booleanObj = ObjectFactory.CreateInstance<BooleanClass>(); if (!bool.TryParse(fileContent, out booleanObj.boolean)) { booleanObj.boolean = false; } ctx.AddObjectToAsset("main", booleanObj); ctx.SetMainObject(booleanObj); Debug.Log("Imported Boolean value: " + booleanObj.boolean); } }

You can also use ScriptedImporter settings and extraData in the same AssetImporterEditor:

using UnityEditor;
using UnityEditor.AssetImporters;

[CustomEditor(typeof(SomeScriptedImporter))] [CanEditMultipleObjects] public class SomeImporterEditor : ScriptedImporterEditor { // ...

public override void OnInspectorGUI() { serializedObject.Update(); extraDataSerializedObject.Update();

// Use propertyDrawers and custom GUI for any property from both serializedObject and extraDataSerializedObject.

extraDataSerializedObject.ApplyModifiedProperties(); serializedObject.ApplyModifiedProperties();

ApplyRevertGUI(); } }

[ScriptedImporter(0, ".someFile")] public class SomeScriptedImporter : ScriptedImporter { public override void OnImportAsset(AssetImportContext ctx) { // ... } }
