创建一个 3D 按钮。
此按钮的作用与使用 GUI.Button 绘制的按钮类似,但它有一个 3D 位置并且是由 handle 函数绘制的。\ \ \ 在场景视图中显示为矩形的按钮手柄。\ \ 将以下脚本作为 ButtonExample.cs 添加到 Assets 文件夹,然后将 ButtonExample 组件添加到场景中的对象。
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!"); } }
