Unity双击全屏UI按钮、长按UI按钮

1.长按按钮

将下面的代码挂载到按钮上，去掉按钮本射的Button组件

using System.Collections;
using UnityEngine;
using UnityEngine.Events;
using UnityEngine.EventSystems;

public class LongPressButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
{
    public UnityEvent OnPressDown;
    bool _isPressed = false;

    IEnumerator DetectPress()
    {
        while(_isPressed)
        {
            if(OnPressDown != null)
            {
                OnPressDown.Invoke();
            }
            yield return new WaitForSeconds(0.1f);
        }
    }

    public void OnPointerDown(PointerEventData eventData)
    {
        _isPressed = true;
        StartCoroutine(DetectPress());
    }

    public void OnPointerUp(PointerEventData eventData)
    {
        _isPressed = false;
    }
}

2.双击按钮

 将下面的代码挂载到需要双击的图片上，如双击全屏

using UnityEngine;
using UnityEngine.EventSystems;

public class DoubleClickHandler : MonoBehaviour, IPointerClickHandler
{
    public delegate void OnDoubleClick();
    public OnDoubleClick OnDoubleClickHandle;

    public float clickInterval = 0.3f; // 连续点击间隔阈值
    private float lastClickTime;
    public void OnPointerClick(PointerEventData eventData)
    {
        float timeSinceLastClick = UnityEngine.Time.time - lastClickTime;

        if (timeSinceLastClick <= clickInterval)
        {
            if(OnDoubleClickHandle != null)
            {
                OnDoubleClickHandle();
            }
        }

        lastClickTime = UnityEngine.Time.time;
    }
}
