설명

Disposable helper struct for automatically setting and reverting Handles.color and/or Handles.matrix.

This struct allows you to temporarily set the value of Handles.color and/or Handles.matrix inside of a block of code and automatically revert them to their previous values when the scope is exited.

using UnityEditor;
using UnityEngine;

// a custom editor that draws a labeled circle around the selected MeshRenderer in the scene view [CustomEditor(typeof(MeshRenderer))] public class MeshRendererEditor : Editor { protected virtual void OnSceneGUI() { MeshRenderer meshRenderer = (MeshRenderer)target;

// get an orientation pointing from the selected object to the camera Vector3 cameraToTarget = Camera.current.transform.position - meshRenderer.transform.position; Quaternion billboardOrientation = Quaternion.LookRotation(cameraToTarget, Camera.current.transform.up);

// set the handle matrix to the target's position, oriented facing the camera Matrix4x4 matrix = Matrix4x4.TRS(meshRenderer.transform.position, billboardOrientation, Vector3.one); using (new Handles.DrawingScope(Color.magenta, matrix)) { // draw a magenta circle around the selected object with a label at the top Vector3 size = meshRenderer.bounds.size; float radius = Mathf.Max(size.x, size.y, size.z); Handles.DrawWireArc(Vector3.zero, Vector3.forward, Vector3.right, 360f, radius); Handles.Label(Vector3.up * radius, meshRenderer.name); } } }

변수

originalColorThe value of Handles.color at the time this DrawingScope was created.
originalMatrixThe value of Handles.matrix at the time this DrawingScope was created.

생성자

Handles.DrawingScopeCreate a new DrawingScope and set Handles.color and/or Handles.matrix to the specified values.

Public 함수

DisposeAutomatically reverts Handles.color and Handles.matrix to their values prior to entering the scope, when the scope is exited. You do not need to call this method manually.
