我正在尝试使用 unity5 在线学习太空射击教程，但我遇到了刚体问题。

我意识到刚体已被替换为 Component.GetComponent() 但我想创建一个变量而不是全部输入。

我使用 Component.GetComponent() 收到大量错误，但不明白出了什么问题。

这是我的代码片段，我试图用夹子限制运动：

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)
        );
    }
}

这是它给我的大量错误：

Finished updating scripts / assemblies

Some scripts have compilation errors which may prevent obsolete API usages to get updated. Obsolete API updating will continue automatically after these errors get fixed.

我觉得我错过了一些重要而明显的东西，因为这不是很多代码来保证这么多错误。

在使用非静态类函数之前，您应该首先创建一个对象的实例。

在您的情况下，它很可能是附加了 RigidBody 组件的 gameObject。这是代码示例：

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

分别重做代码中的其他字符串。
