基于Unity3d的事件系统和C#的委托特性，提供一下通用事件监听代码，挺真通用的说，反正用过都说好
lua和C#都能通用，长期在项目中使用，无任何暗病
而网上复制粘贴代码，很容易有空行，（或者前面行号）
代码
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems; //事件系统
namespace kernal
{
public class EventTriggerListener : UnityEngine.EventSystems.EventTrigger
{
public delegate void VoidDelegate(GameObject go);
public VoidDelegate onClick;
public VoidDelegate onDown;
public VoidDelegate onEnter;
public VoidDelegate onExit;
public VoidDelegate onUp;
public VoidDelegate onSelect;
public VoidDelegate onUpdateSelect;
/// <summary>
/// 得到“监听器”组件
/// </summary>
/// <param name="go">监听的游戏对象</param>
/// <returns>
/// 返回监听器
/// </returns>
public static EventTriggerListener Get(GameObject go)
{
EventTriggerListener lister = go.GetComponent<EventTriggerListener>();
if (lister==null)
{
lister = go.AddComponent<EventTriggerListener>();
}
return lister;
}
public override void OnPointerClick(PointerEventData eventData)
{
if (onClick!=null)
{
onClick(gameObject);
}
}
public override void OnPointerDown(PointerEventData eventData)
{
if (onDown != null)
{
onDown(gameObject);
}
}
public override void OnPointerEnter(PointerEventData eventData)
{
if (onEnter != null)
{
onEnter(gameObject);
}
}
public override void OnPointerExit(PointerEventData eventData)
{
if (onExit != null)
{
onExit(gameObject);
}
}
public override void OnPointerUp(PointerEventData eventData)
{
if (onUp != null)
{
onUp(gameObject);
}
}
public override void OnSelect(BaseEventData eventData)
{
if (onSelect != null)
{
onSelect(gameObject);
}
}
public override void OnUpdateSelected(BaseEventData eventData)
{
if (onUpdateSelect != null)
{
onUpdateSelect(gameObject);
}
}
}//class_end
}
使用方法
EventTriggerListener.Get(Btn_10_Diamonds.gameObject).onClick += Purchase10Diamend;
另外，去除代码空行方法
Enter: Ctrl+HFind what: ^(?([^\r\n])\s)*\r?$\r?\nReplace with: [Empty]Look in: Current DocumentFind Option: Use Regular ExpressionsClick: Replace All
解释一下正则表达式^:b*$\n，^表示一行的开始，$表示一行的结束，:b表示空格或tab，*表示0个或多个。\n表示换行符。
^(?([^\r\n])\s)*\r?$\r?\n
上面截图有点错。。。。。。。。。。。。
继承类避免滚动和点击冲突
namespace kernal
{
/// <summary>
/// 避免和滚动事件冲突的点击事件；用一个很笨的方法做延迟，解决点击和 Drag 冲突问题
/// </summary>
public class EventGesture:EventTriggerListener
{
static bool isSrolling = false;
public override void OnPointerClick(PointerEventData eventData)
{
if (isSrolling == true) return;
base.OnPointerClick(eventData);
}
public override void OnDrag(PointerEventData eventData)
{
isSrolling = true;
base.OnDrag(eventData);
}
public override void OnPointerUp(PointerEventData eventData)
{
Invoke("SetScrollUp",0.01f);
//只能判断是否在ui上
//if (EventSystem.current.IsPointerOverGameObject(finterid)) {
// //base.onPointerClick;
//}
//isSrolling = false;
base.OnPointerUp(eventData);
}
void SetScrollUp()
{
isSrolling = false;
}
}
}
