id | The control ID of the handle. |
rotation | 圆盘的旋转。 |
position | 圆盘的中心。 |
axis | 要围绕其旋转的轴。 |
size | 世界空间中圆盘的大小。 |
cutoffPlane | 如果为 true,则只有正面的半个圆圈是可绘制/可拖动的。当您有许多用于避免混乱的重叠的旋转轴时(例如在默认旋转工具中),这非常有用。 |
snap | 要贴靠到的网格大小。 |
Quaternion 通过用户与手柄的交互修改的新旋转值。如果用户没有移动手柄,则将返回您传递给相应函数的值。

**注意**:如果您希望拥有恒定屏幕大小的手柄,请使用 HandleUtility.GetHandleSize。

场景视图中的圆盘手柄。
// Name this script "DiscHandleEditor" using UnityEngine; using UnityEditor;
[CustomEditor(typeof(DiscHandle))] [CanEditMultipleObjects] public class DiscHandleEditor : Editor { public void OnSceneGUI() { DiscHandle t = (target as DiscHandle);
EditorGUI.BeginChangeCheck(); Quaternion rot = Handles.Disc(t.rot, t.transform.position, new Vector3(1, 1, 0), 5, false, 1);
if (EditorGUI.EndChangeCheck()) { Undo.RecordObject(target, "Disc Rotate"); t.rot = rot; t.Update(); } } }
附加到此手柄的脚本:
// Name this script "DiscHandle" using UnityEngine; [ExecuteInEditMode] public class DiscHandle : MonoBehaviour { public Quaternion rot = Quaternion.identity; public void Update() { transform.rotation = rot; } }
