Unity 框架(一)

当项目需求中，后期可能接入多种输入设备的时候，可以借鉴一下以下代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;

public abstract class TInputBase : MonoBehaviour{

    public abstract InputSchemeEventArgs HandleInput();

    public delegate void InputSchemeEventHandler(TInputBase sender, TInputBase.InputSchemeEventArgs inputArgs);

    //Packaging Input data
    protected InputSchemeEventArgs GetInputData(GameObject currentObject,EnumList.InputResultTypes inputStyle)
    {
        return new InputSchemeEventArgs
        {
            CurrentGazeObject = currentObject,

            Style = inputStyle,
        };
    }


    //Notify delegates during the update method
    protected void NotifyDelegates(InputSchemeEventArgs data)
    {
        if (InputSchemeEvent != null)
