找不到CharacterMotor

Question

請幫忙。 我正在向標准FPS字符控制器添加運行和蹲伏腳本，並收到以下錯誤消息：錯誤CS0246：找不到類型或名稱空間名稱'CharacterMotor'。 您是否缺少裝配參考？

public class RunAndCrouch : MonoBehaviour {

public float walkSpeed = 7; // regular speed
 public float crchSpeed = 3; // crouching speed
 public float runSpeed = 20; // run speed

 private CharacterMotor chMotor;
 private Transform tr;
 private float dist; // distance to ground

 // Use this for initialization
 void Start () 
 {
     chMotor =  GetComponent<CharacterMotor>();
     tr = transform;
     CharacterController ch = GetComponent<CharacterController>();
     dist = ch.height/2; // calculate distance to ground
 }

 // Update is called once per frame
 void FixedUpdate ()
 {
     float vScale = 1.0f;
     float speed = walkSpeed;

     if ((Input.GetKey("left shift") || Input.GetKey("right shift")) &&   chMotor.grounded)
     {
         speed = runSpeed;            
     }

     if (Input.GetKey("c"))
     { // press C to crouch
         vScale = 0.5f;
         speed = crchSpeed; // slow down when crouching
     }

     chMotor.movement.maxForwardSpeed = speed; // set max speed
     float ultScale = tr.localScale.y; // crouch/stand up smoothly 

     Vector3 tmpScale = tr.localScale;
     Vector3 tmpPosition = tr.position;

     tmpScale.y = Mathf.Lerp(tr.localScale.y, vScale, 5 * Time.deltaTime);
     tr.localScale = tmpScale;

     tmpPosition.y += dist * (tr.localScale.y - ultScale); // fix vertical position        
     tr.position = tmpPosition;
 }

}

蹲伏（有效。只需將其拖動到FPSController

public class Crouch : MonoBehaviour {

CharacterController characterCollider;


void Start () 
{
    characterCollider = gameObject.GetComponent<CharacterController> ();
}


void Update () 
{
    if (Input.GetKey (KeyCode.C))
    {
        characterCollider.height = 1.0f;
    }
    else
    {
        characterCollider.height =1.8f;
    }

}

}

Answer 1

CharaterMotor 曾經是 Unity標准資產的一部分，但現在不再是。 CharaterMotor已棄用多年。

您現在應該使用作為標准資產一部分的FirstPersonController來移動角色，我建議您停止使用CharaterMotor 。

如果您已閱讀以上內容，但仍想使用CharaterMotor請在此處查看Unity的存檔。 選擇舊的Unity版本，然后轉到下拉按鈕並下載標准資產。 您也可以在這里得到它。

Answer 2

在普通的Visual Studio項目中，您必須將文件添加到項目中。 但是Unity為您做到了。 添加文件時，它將重新生成整個c＃項目。 如果CharacterMotor是資產文件夾中的腳本，則無需執行任何操作。 所以試試這個：

• 檢查CharacterMotor是否在您的資產文件夾中

• 關閉Visual Studio，然后通過雙擊腳本再次統一打開它

編輯關於您關於蹲伏模式的評論：

如果按下鍵， Input.GetKey返回true。 而是使用Input.GetKeyDown 。 按下該鍵后，僅一幀將返回true。 設置一個類變量以記住蹲伏狀態，如下所示：

private void bool _crouching;

private void Update () 
{ 
    if (Input.GetKeyDown (KeyCode.C)) 
    { 
        _crouching = !_crouching;
        characterCollider.height = _crouching ? 1.0f : 1.8f; 
    } 
}

這是角色運動腳本的鏈接，現在已從js轉換為c＃
