Definition

public static void RefreshAvailableTools()

Remarks

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

Examples

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;}
