Untiy添加双鼠标功能记录

   找到了一个插件MulitpleMouse​​​​​​​，导入Unity，里面有一个MulitpleMouse脚本，通过这个脚本可以获取到电脑上插着几个USB接口的鼠标，并对鼠标进行操作检测，然后我自己写了一个脚本，可以让鼠标对UI进行互动。

using System.Collections;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class MouseManager : MonoBehaviour {

	private bool HideCursor = true;

	//public bool isClick = false;
	public float tempTime = 0;//计时器

	public EventSystem _mEventSystem;
	public GraphicRaycaster gra;

	List<RaycastResult> list = new List<RaycastResult>();

	// Use this for initialization
	void Start ()
	{
		_mEventSystem = GameObject.Find("EventSystem").GetComponent<EventSystem>();
		gra = GameObject.Find("CanvasUI").GetComponent<GraphicRaycaster>();
	}
	
	// Update is called once per frame
	void Update () {
		if (PublicClass.MouseOneIsPlay)//如果被点击
		{
			tempTime += Time.deltaTime;
			if (tempTime > 1.5)
			{
				tempTime = 0;
				PublicClass.MouseOneIsPlay = false;
			}
		}
		if (PublicClass.MouseTwoIsPlay)//如果被点击
		{
			tempTime += Time.deltaTime;
			if (tempTime > 1.5)
			{
				tempTime = 0;
				PublicClass.MouseTwoIsPlay = false;
			}
		}
		if (HideCursor)
		{
			Cursor.lockState = CursorLockMode.Locked;
			//SetCursorPos(0, 280);//强制设置坐标
		}
		if (Input.GetKeyDown(KeyCode.Escape))
		{
			HideCursor = false;
		}

		if (MulitpleMouse.OnMouseButton(0, 0) && PublicClass.MouseOneIsPlay == false)
		{
			PublicClass.MouseOneIsPlay = true;
			list = GraphicRaycaster(MulitpleMouse.GetMousePosZeroOnLeftButtom(0));
			List<Button> Btns = new List<Button>();
			for (int i = 0; i < list.Count; i++)
			{
				Button btn_1 = null;
				btn_1 = list[i].gameObject.GetComponent<Button>();
				if (btn_1 != null)
				{
					Btns.Add(btn_1);
				}
			}
			if (Btns.Count>0)
			{
				if (Btns[0].GetComponent<Remove>())
				{
					Btns[0].GetComponent<Remove>().Index = 0;
				}
				if (Btns[0].GetComponent<Tool>())
				{
					Btns[0].GetComponent<Tool>().index = 0;
				}
				Btns[0].onClick.Invoke();
			}
			List<Toggle> Togs = new List<Toggle>();
			for (int i = 0; i < list.Count; i++)
			{
				Toggle tog_1 = null;
				tog_1 = list[i].gameObject.GetComponent<Toggle>();
				if (tog_1 != null)
				{
					Togs.Add(tog_1);
				}
			}
			if (Togs.Count > 0)
			{
				Togs[0].onValueChanged.Invoke(true);
			}
			Debug.Log("Togs::" + Togs.Count);
		}

		if (MulitpleMouse.OnMouseButton(1, 0) && PublicClass.MouseTwoIsPlay == false)
		{
			PublicClass.MouseTwoIsPlay = true;
		   list = GraphicRaycaster(MulitpleMouse.GetMousePosZeroOnLeftButtom(1));
			List<Button> Btns = new List<Button>();
			for (int i = 0; i < list.Count; i++)
			{
				Button btn_1 = null;
				btn_1 = list[i].gameObject.GetComponent<Button>();
				if (btn_1 != null)
				{
					Btns.Add(btn_1);
				}
			}
			if (Btns.Count > 0)
			{
				if (Btns[0].GetComponent<Remove>())
				{
					Btns[0].GetComponent<Remove>().Index = 1;
				}
				if (Btns[0].GetComponent<Tool>())
				{
					Btns[0].GetComponent<Tool>().index = 1;
				}
				Btns[0].onClick.Invoke();
			}
			List<Toggle> Togs = new List<Toggle>();
			for (int i = 0; i < list.Count; i++)
			{
				Toggle tog_1 = null;
				tog_1 = list[i].gameObject.GetComponent<Toggle>();
				if (tog_1 != null)
				{
					Togs.Add(tog_1);
				}
			}
			if (Togs.Count > 0)
			{
				Togs[0].onValueChanged.Invoke(true);
			}
		}
	}

	private List<RaycastResult> GraphicRaycaster(Vector2 pos)
	{
		var mPointerEventData = new PointerEventData(_mEventSystem);
		mPointerEventData.position = pos;
		List<RaycastResult> results = new List<RaycastResult>();

		gra.Raycast(mPointerEventData, results);
		return results;
	}
}
