Component.GetComponent （）导致大量的错误

Question

我想跟随Unity5的空间射击游戏教程，我遇到了刚体问题。

我知道刚体已经被Component.GetComponent（）取代，但我想做一个变量而不是全部输入。

我得到了使用Component.GetComponent（）错误的TON，并不明白什么是错的。

这里是我的代码片段，我试图约束带夹具运动：

using UnityEngine; 
using System.Collections; 

public class PlayerController : MonoBehaviour { 

    public float speed; 
    public float xMin, zMin, xMax, zMax; 

    void FixedUpdate(){ 
     float moveHorizontal = Input.GetAxis("Horizontal"); 
     float moveVertical = Input.GetAxis("Vertical"); 

     Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical); 
     Component.GetComponent<Rigidbody>().velocity = movement*speed; 

     Component.GetComponent<Rigidbody>().position = new Vector3 
     (
      Mathf.Clamp(Component.GetComponent<Rigidbody>().position.x, xMin, xMax), 
      0.0f, 
      Mathf.Clamp(Component.GetComponent<Rigidbody>().position.z, zMin, zMax) 
     ); 
    } 
} 

，这里是错误的spitload它给了我：

我觉得我在想念一些重要的和显而易见的，因为这不是很多的代码来保证这么多的错误。

在使用非静态类函数之前，您应该先创建一个对象的实例。

在你的情况下，它最有可能是附有RigidBody组件的gameObject。下面是代码示例：

gameObject.GetComponent<RigidBody>().velocity = movement * speed; 

分别重做等串在你的代码。
