推荐答案

假设ClickAction是您的脚本，则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 ...
    }
}

名称空间UnityEngine.EventSystems为您提供IPointerClickHandler接口.单击图像后，OnPointerClick中的代码将运行.

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