Transform.position

# [Transform](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform.html).position

public [Vector3](https://docs.unity3d.com/cn/2019.4/ScriptReference/Vector3.html) **position** ;

## 描述

世界空间中的变换位置。

[GameObject](https://docs.unity3d.com/cn/2019.4/ScriptReference/GameObject.html) 的 [Transform](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform.html) 的 [position](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform-position.html) 属性，可以在 Unity Editor 中以及通过脚本来访问该属性。变更该值可移动 [GameObject](https://docs.unity3d.com/cn/2019.4/ScriptReference/GameObject.html)。获得该值可在 3D 世界空间中定位此 [GameObject](https://docs.unity3d.com/cn/2019.4/ScriptReference/GameObject.html)。

```
using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    //movement speed in units per second
    private float movementSpeed = 5f;

void Update()
    {
        //get the Input from Horizontal axis
        float horizontalInput = Input.GetAxis("Horizontal");
        //get the Input from Vertical axis
        float verticalInput = Input.GetAxis("Vertical");

//update the position
        transform.position = transform.position + new Vector3(horizontalInput * movementSpeed * Time.deltaTime, verticalInput * movementSpeed * Time.deltaTime, 0);

//output to log the position change
        Debug.Log(transform.position);
    }
}
```

该示例从水平和垂直轴获取输入，然后通过更改 GameObject 的位置将它向上/向下或向左/向右移动。
