public void OnDrawHandles ();

説明

Implement this method to draw non-interactive handles when a custom editor tool is available.

This method is called when a custom editor tool is available for the current selection. Use this method to draw information in the SceneView. A custom editor tool is an EditorTool with a target type specified by the EditorToolAttribute.

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

[EditorTool("Light Tool", typeof(Light))] public class CustomEditorLightTool : EditorTool, IDrawSelectedHandles { // OnToolGUI is called when the tool is active. Interactive handles belong here. public override void OnToolGUI(EditorWindow window) { var position = Tools.handlePosition;

EditorGUI.BeginChangeCheck();

var result = Handles.PositionHandle(position, Quaternion.identity);

if (EditorGUI.EndChangeCheck()) { var delta = result - position;

Undo.RecordObjects(Selection.transforms, "Move Lights");

foreach (var light in targets) ((Light)light).transform.position += delta; } }

// OnDrawHandles is called when a custom editor tool is available for the current selection. Use this to draw // information in the SceneView when any object matching the target type is selected. public void OnDrawHandles() { foreach (var light in targets) { // If the Light Tool is active, draw a green radius handle. If it is not active, make the radius blue. Handles.color = EditorTools.IsActiveTool(this) ? Color.green : Color.blue; Handles.RadiusHandle(Quaternion.identity, ((Light)light).transform.position, 2f); Handles.color = Color.white; } } }
