Vector3 通过用户与手柄的交互修改的新值。如果用户没有移动手柄,则将返回您传递给相应函数的值。
创建一个场景视图缩放手柄。
此手柄的行为类似于内置缩放工具
**注意**:如果您希望拥有恒定屏幕大小的手柄,请使用 HandleUtility.GetHandleSize。

每当您选择游戏对象时将会出现的缩放手柄。
// Name this script "ScaleAtPointEditor" using UnityEngine; using UnityEditor;
[CustomEditor(typeof(ScaleAtPoint))] [CanEditMultipleObjects] public class ScaleAtPointEditor : Editor { public void OnSceneGUI() { ScaleAtPoint t = (target as ScaleAtPoint);
EditorGUI.BeginChangeCheck(); Vector3 scale = Handles.ScaleHandle(t.scale, Vector3.zero, Quaternion.identity, 1); if (EditorGUI.EndChangeCheck()) { Undo.RecordObject(target, "Scaled ScaleAt Point"); t.scale = scale; t.Update(); } } }
附加到此游戏对象的脚本:
// Name this script "ScaleAtPoint" using UnityEngine; [ExecuteInEditMode] public class ScaleAtPoint : MonoBehaviour { public Vector3 scale = Vector3.one; public void Update() { transform.localScale = scale; } }
