Question

尝试创建运行脚本。访问播放器的CharacterMotor并提高移动速度，但编译器说这些对象不存在。使用股票Fisrt人物角色控制器

错误CS1061：输入UnityEngine.Component' does not contain a definition for CharacterMotor'并且找不到扩展方法CharacterMotor' of type UnityEngine.Component'（您是否缺少using指令或程序集引用？）

public class PlayerRun : MonoBehaviour {
public GameObject _player;
private float _runSpeed = 10;
private float _defaultSpeed;

// Use this for initialization
void Start () 
{
    _defaultSpeed = _player.GetComponent("CharacterMotor").CharacterMotor.maxForwardSpeed;
}

// Update is called once per frame
void Update () 
{
    if (Input.GetKeyDown(KeyCode.LeftShift))
    {
        _player.GetComponent("CharacterMotor").CharacterMotor.maxForwardSpeed = _runSpeed;
        _player.GetComponent("CharacterMotor").CharacterMotor.maxSidewaysSpeed = _runSpeed;
        _player.GetComponent("CharacterMotor").CharacterMotor.maxBackwardsSpeed = _runSpeed;
    }
    else
    {
        if (_player.GetComponent("CharacterMotor").CharacterMotor.maxForwardSpeed == _runSpeed)
        {
            _player.GetComponent("CharacterMotor").CharacterMotor.maxForwardSpeed = _defaultSpeed;
        _player.GetComponent("CharacterMotor").CharacterMotor.maxSidewaysSpeed = _defaultSpeed;
        _player.GetComponent("CharacterMotor").CharacterMotor.maxBackwardsSpeed = _defaultSpeed;
        }
    }
}

}

Answer 1

看起来你刚从UnityScript转到C＃？

您应该使用generic的GetComponent形式：

_defaultSpeed = _player.GetComponent<CharacterMotor>().maxForwardSpeed;

如果您致电GetComponent(typeof(T))，您将获得Component类型的引用。您可以将结果转换为T，但为什么要这么麻烦？您可以轻松地调用GetComponent<T>()来获取该类型的引用。

从另一个脚本访问Character Motor
