Unity 关于手柄摇杆和键值的测试

之前的关于手柄的帖子有网友说测试的不准，所以今天写了一个测试键值的脚本，希望能帮到各位

下面是关于测试的代码，里面加了注释：

using UnityEngine;
using System.Collections;
using System;


/// <summary>
/// 测试游戏手柄键值
/// </summary>
public class PlayerJoystickClass : MonoBehaviour
{
    private string currentButton;//当前按下的按键
    private string currentAxis;//当前移动的轴向
    private float axisInput;//当前轴向的值

    void Update()
    {
        getAxis();
        getButtons();
    }

    /// <summary>
    /// Get Button data of the joysick
    /// </summary>
    void getButtons()
    {
        var values = Enum.GetValues(typeof(KeyCode));//存储所有的按键
        for (int x = 0; x < values.Length; x++)
        {
            if (Input.GetKeyDown((KeyCode)values.GetValue(x)))
            {
                currentButton = values.GetValue(x).ToString();//遍历并获取当前按下的按键
            }
        }
    }

    /// <summary>

    /// </summary>
    void getAxis()
    {
        if (Input.GetAxisRaw("X axis") > 0.3 || Input.GetAxisRaw("X axis") < -0.3)

        }

        if (Input.GetAxisRaw("6th axis") > 0.3 || Input.GetAxisRaw("6th axis") < -0.3)

            axisInput = Input.GetAxisRaw("6th axis");

        {

        }

        if (Input.GetAxisRaw("9th axis") > 0.3 || Input.GetAxisRaw("9th axis") < -0.3)
        {
            currentAxis = "9th axis";
            axisInput = Input.GetAxisRaw("9th axis");
        }

            currentAxis = "12th axis";
            axisInput = Input.GetAxisRaw("12th axis");
        }

        if (Input.GetAxisRaw("13th axis") > 0.3 || Input.GetAxisRaw("13th axis") < -0.3)

            axisInput = Input.GetAxisRaw("14th axis");
        }
    }

    /// <summary>
    /// show the data onGUI
    /// </summary>
    void OnGUI()
    {
        GUI.TextArea(new Rect(0, 0, 250, 50), "Current Button : " + currentButton);//使用GUI在屏幕上面实时打印当前按下的按键
        GUI.TextArea(new Rect(0, 100, 250, 50), "Current Axis : " + currentAxis);//使用GUI在屏幕上面实时打印当前按下的轴
        GUI.TextArea(new Rect(0, 200, 250, 50), "Axis Value : " + axisInput);//使用GUI在屏幕上面实时打印当前按下的轴的量
    }
}

连接手柄后，当你按下手柄的键位和轴向时，都会在屏幕中输出出来，使用的话调用Input的API就可以了
