Handles.Button

参数

返回

bool 当用户单击按钮时，返回 true。

描述

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!");
    }
}
