public static EditorApplication.SerializedPropertyCallbackFunction contextualPropertyMenu ;


Callback raised whenever the user contex-clicks on a property in an Inspector.

This callback is useful to add custom contextual menu items which can perform operations on a particular property.

//This script creates a new menu item named "Example" in the Window dropdown menu. Press this to create the Example window.

using UnityEngine; using UnityEditor; using System.Collections;

public class Example : EditorWindow { [MenuItem("Window/Example")]

public static void ShowWindow() { EditorWindow.GetWindow(typeof(Example)); }

void OnEnable() { EditorApplication.contextualPropertyMenu += OnPropertyContextMenu; }

void OnDestroy() { EditorApplication.contextualPropertyMenu -= OnPropertyContextMenu; }

void OnPropertyContextMenu(GenericMenu menu, SerializedProperty property) { // show a custom menu item only for Vector3 properties if (property.propertyType != SerializedPropertyType.Vector3) return;

// and only when called on a Transform component if (property.serializedObject.targetObject.GetType() != typeof(Transform)) return;

var propertyCopy = property.Copy(); menu.AddItem(new GUIContent("Randomize Vector"), false, () => { propertyCopy.vector3Value = Random.insideUnitSphere * 5; propertyCopy.serializedObject.ApplyModifiedProperties(); }); } }
