# GetAxis

学习使用 GetAxis 获取基于轴的输入，并在 Input Manager 中配置这些轴的参数。

如何在 Unity 中为游戏获取基于轴的输入，以及如何通过 Input Manager 修改这些轴

本教程包含在“[初级编程](https://learn.unity.com/project/chu-ji-bian-cheng?language=zh)”项目中。

## **AxisExample**

```csharp
using UnityEngine;
using System.Collections;

public class AxisExample : MonoBehaviour
{
    public float range;
    public GUIText textOutput;
    
    
    void Update () 
    {
        float h = Input.GetAxis("Horizontal");
        float xPos = h * range;
        
        transform.position = new Vector3(xPos, 2f, 0);
        textOutput.text = "Value Returned: "+h.ToString("F2");  
    }
}
```

## **AxisRawExample**

```csharp
using UnityEngine;
using System.Collections;

public class AxisRawExample : MonoBehaviour
{
    public float range;
    public GUIText textOutput;
    
    
    void Update () 
    {
        float h = Input.GetAxisRaw("Horizontal");
        float xPos = h * range;
        
        transform.position = new Vector3(xPos, 2f, 0);
        textOutput.text = "Value Returned: "+h.ToString("F2");  
    }
}
```

## **DualAxisExample**

```csharp
using UnityEngine;
using System.Collections;

public class DualAxisExample : MonoBehaviour 
{
    public float range;
    public GUIText textOutput;
    
    
    void Update () 
    {
        float h = Input.GetAxis("Horizontal");
        float v = Input.GetAxis("Vertical");
        float xPos = h * range;
        float yPos = v * range;
        
        transform.position = new Vector3(xPos, yPos, 0);
        textOutput.text = "Horizontal Value Returned: "+h.ToString("F2")+"\nVertical Value Returned: "+v.ToString("F2");    
    }
}
```
