    您可以使用。创建自己的单击处理程序

     界面和
    <a href="https://docs.unity3d.com/ScriptReference/Events.UnityEvent.html" rel="nofollow noreferrer">
       <code>
 UnityEvent
 </code>
    </A>
    ：
  
   <pre>
 <code>
 public class TextButton : MonoBehaviour, IPointerClickHandler
{
 // add callbacks in the inspector like for buttons
 public UnityEvent onClick;

public void OnPointerClick(PointerEventData pointerEventData)
    {
        //Output to console the clicked GameObject's name and the following message. You can replace this with your own actions for when clicking the GameObject.
        Debug.Log(name + " Game Object Clicked!", this);

// invoke your event
        onClick.Invoke();
    }
}

 </pre>

      确保一个
       <code>
 EventSystem
 </code>
       在场景中存在以允许单击检测。对于非UI游戏对象的点击检测，请确保
       <code>
 PhysicsRaycaster
 </code>
       附在
       <code>
 Camera
 </code>
      。

    或者你可以使用

     零件。

    两者基本上会或多或少地做同样的事情：

    第一个的巨大优势是你可以轻松地增强它，例如通过改变按钮颜色的视觉反馈：
