推荐答案

假设 ClickAction 是您的脚本，您可以通过以下方式实现 OnClick 功能:

Supposing that ClickAction is your script, you could implement the OnClick functionality in the following way:

using UnityEngine.EventSystems;

public class ClickAction : MonoBehaviour, IPointerClickHandler
{ 
    public void OnPointerClick(PointerEventData eventData)
    {
        // OnClick code goes here ...
    }
}

命名空间 UnityEngine.EventSystems 为您提供 IPointerClickHandler 接口.当你的图片被点击时，OnPointerClick里面的代码会运行.

The namespace UnityEngine.EventSystems supplies you with the IPointerClickHandler interface. When your image is clicked, the code inside OnPointerClick will run.
