public static void RefreshAvailableTools ();

描述

Call RefreshAvailableTools to rebuild the contents of the Scene View Tools Overlay.

This method is useful when a tool can change the value of EditorTool.IsAvailable outside of selection and tool change events.

using System;
using UnityEditor;
using UnityEditor.EditorTools;
using UnityEngine;

// An example of a tool that may be made available or unavailable in situations other than selection changes. [EditorTool("Conditional Tool", typeof(Transform))] class ConditionallyAvailable : EditorTool { bool m_IsAvailable; void OnEnable() => EditorApplication.update += UpdateAvailable; void OnDisable() => EditorApplication.update -= UpdateAvailable;

// This tool is enabled and disabled in 10 second intervals. void UpdateAvailable() { var time = DateTime.Now;

if (m_IsAvailable != ((time.Second / 10) % 2 == 0)) { m_IsAvailable = !m_IsAvailable; // Because the tool is changing availability arbitrarily, it is necessary to manually refresh the UI. ToolManager.RefreshAvailableTools(); } }

// When a tool is available, it is shown in the Tools Overlay. If not available, it is hidden. public override bool IsAvailable() => m_IsAvailable; }
