与Unity中的自定义UI元素进行交互 [英] Interact with custom UI element in Unity

问题描述

我在与自定义UI元素交互时遇到问题.我有一个自定义模式窗口，当我将鼠标悬停在对象上时会显示该窗口，然后当鼠标离开模式窗口区域时我想将其消失，但是我找不到解决方法. 层次结构和画布检查器中的游戏对象

I have problem interact with custom UI element. I have a custom modal window which is displayed when I hover mouse over the object and then I want to disappear it when mouse leaves modal window area but I can't find solution how to do it. Game Objects in the hierarchy and canvas inspector

我在互联网上进行搜索，尝试过使用raycasters，但是它无法正常工作，或者我做错了事.

I searched on the internet, I tried it with raycasters but its not working or maybe I doing something wrong.

这是我将鼠标悬停在对象上时如何调用Script ModalWindowScript的方式，以便我可以以某种方式与UI元素进行交互.

This is how I call Script ModalWindowScript when is mouse over object so I can somehow interact with UI elements.

    [SerializeField] GameObject uIModalWindow;
    private void Start()
    { 
        uIModalWindow.SetActive(false);
    }

    private void OnMouseEnter()
    {
        var mousePos = Input.mousePosition;
        Debug.Log(gameObject.name);
        uIModalWindow.transform.position = mousePos;
        uIModalWindow.SetActive(true);
    }

    private void OnMouseExit()
    {
        uIModalWindow.AddComponent<ModalWindowScript>();
    }

预期结果是，当鼠标离开模态窗口区域时，模态窗口将消失.但是实际状态是我无法找到如何与UI进行通信.

Expected result is that modal window will disappear when mouse will leave the modal window area. But actual status is that I can't find out how to communicate with UI.

HoverOverObject ModalWindowScript

推荐答案

您需要实现IPointerEnterHandler& IPointerExitHandler接口可获取此类解决方案以获取适当的事件:

You need to implement the IPointerEnterHandler & IPointerExitHandler interface to get this kind of solution to get the proper events:

public class HoverOverObject : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler

    [SerializeField] GameObject uIModalWindow;
    private void Start()
    { 
        uIModalWindow.SetActive(false);
    }

    public void OnPointerEnter(PointerEventData e)
    {
        var mousePos = Input.mousePosition;
        Debug.Log(gameObject.name);
        uIModalWindow.transform.position = mousePos;
        uIModalWindow.SetActive(true);
    }

    public void OnPointerExit(PointerEventData e)
    {
        uIModalWindow.AddComponent<ModalWindowScript>();
    }
}

注意更改的代码:添加了接口，更改了方法的名称，将方法的可访问性从私有更改为公共.

Note changed code: Added Interfaces, Changed name of methods, Changed accessibility from private to public on methods.
