Description
创建一个 3D 按钮。
This button works like one drawn with GUI.Button, but it has a 3D position and is drawn by a handle function.
Button Handle as a rectangle in the Scene View.
Add the following script to your Assets folder as ButtonExample.cs and add the ButtonExample component to an object in a Scene.
using UnityEngine;
public class ButtonExample : MonoBehaviour {}
将以下脚本作为 ButtonExampleEditor.cs 添加到 Assets/Editor，然后选择包含 ButtonExample 组件的对象。
using UnityEditor; using UnityEngine;
[CustomEditor(typeof(ButtonExample)), CanEditMultipleObjects] class ButtonExampleEditor : Editor { protected virtual void OnSceneGUI() { ButtonExample buttonExample = (ButtonExample)target;
Vector3 position = buttonExample.transform.position + Vector3.up * 2f; float size = 2f; float pickSize = size * 2f;
if (Handles.Button(position, Quaternion.identity, size, pickSize, Handles.RectangleHandleCap)) Debug.Log("The button was pressed!"); } }
