SceneAsset is used to reference Scene objects in the Editor.
This can be used as the type for ObjectField UI elements, to allow the user to pick a Scene object as the value of the field.
This example shows how to pick a Scene in the editor. The ScenePicker component is placed on a game object in the Scene:
using UnityEngine;
public class ScenePicker : MonoBehaviour { [SerializeField] public string scenePath; }
The ScenePickerEditor script must be in the Editor directory of the project. It provides the custom inspector in the editor that uses the SceneAsset class in an ObjectField to allow the user to pick a Scene.
using UnityEngine; using UnityEditor;
[CustomEditor(typeof(ScenePicker), true)] public class ScenePickerEditor : Editor { public override void OnInspectorGUI() { var picker = target as ScenePicker; var oldScene = AssetDatabase.LoadAssetAtPath<SceneAsset>(picker.scenePath);
serializedObject.Update();
EditorGUI.BeginChangeCheck(); var newScene = EditorGUILayout.ObjectField("scene", oldScene, typeof(SceneAsset), false) as SceneAsset;
if (EditorGUI.EndChangeCheck()) { var newPath = AssetDatabase.GetAssetPath(newScene); var scenePathProperty = serializedObject.FindProperty("scenePath"); scenePathProperty.stringValue = newPath; } serializedObject.ApplyModifiedProperties(); } }

FindObjectOfType | 返回第一个类型为 type 的已加载的激活对象。 |
FindObjectsOfType | 返回所有类型为 type 的已加载的激活对象的列表。 |
Instantiate | 克隆 original 对象并返回克隆对象。 |
bool | 该对象是否存在? |
operator != | 比较两个对象是否引用不同的对象。 |
operator == | 比较两个对象引用,判断它们是否引用同一个对象。 |
