c# - 在 Unity3D 中使用第一人称 Controller 在空中移动，c#

Question

我目前正在尝试在我试图在我的项目中实现的这个第一人称角色 Controller 中启用空中移动。目前，玩家在空中时会失去所有移动控制。

我试图在跳跃机制中复制正常的移动控制，但无济于事。对于问题的简单性，我深表歉意，在编码方面我是一个新手。

非常感谢所有阅读本文的人:)

   [SerializeField] private string verticalInputName;
   [SerializeField] private float movementSpeed;

   private CharacterController charController;

   [SerializeField] private AnimationCurve jumpFallOff;
   [SerializeField] private float jumpMultiplier;
   [SerializeField] private KeyCode jumpKey;


   private bool isJumping;

   private void Awake()
   {
       charController = GetComponent<CharacterController>();
   }

   private void Update()
   {
       PlayerMovement();
   }

   private void PlayerMovement()
   {
       float horizInput = Input.GetAxis(horizontalInputName) * movementSpeed;
       float vertInput = Input.GetAxis(verticalInputName) * movementSpeed;

       Vector3 forwardMovement = transform.forward * vertInput;
       Vector3 rightMovement = transform.right * horizInput;

       charController.SimpleMove(forwardMovement + rightMovement);

       JumpInput();

   }

   private void JumpInput()
   {
       if (Input.GetKeyDown(jumpKey) && !isJumping)
       {
           isJumping = true;
           StartCoroutine(JumpEvent());
       }
   }

   private IEnumerator JumpEvent()
   {
       charController.slopeLimit = 90.0f;
       float timeInAir = 0.0f;


       do
       {

           float jumpForce = jumpFallOff.Evaluate(timeInAir);
           charController.Move(Vector3.up * jumpForce * jumpMultiplier * Time.deltaTime);

           timeInAir += Time.deltaTime;

           yield return null;
       } while (!charController.isGrounded && charController.collisionFlags != CollisionFlags.Above);

       float horizInput = Input.GetAxis(horizontalInputName) * movementSpeed;
       float vertInput = Input.GetAxis(verticalInputName) * movementSpeed;

       Vector3 forwardMovement = transform.forward * vertInput;
       Vector3 rightMovement = transform.right * horizInput;

       charController.SimpleMove(forwardMovement + rightMovement);
       isJumping = false;
   }
}

文档 recommends每帧只调用 Move 或 SimpleMove 一次，但在协程和 PlayerMovement。

您应该将跳转逻辑移到协程之外，这样您就可以在每次调用之前执行跳转例程逻辑，然后然后对 Move/ 进行一次调用SimpleMove，包括来自跳跃逻辑和玩家输入的计算。

这里有一种方法可以将 Move/SimpleMove 的使用减少到每帧一次调用:

[SerializeField] private string horizontalInputName;
[SerializeField] private string verticalInputName;
[SerializeField] private float movementSpeed;

private CharacterController charController;

[SerializeField] private AnimationCurve jumpFallOff;
[SerializeField] private float jumpMultiplier;
[SerializeField] private KeyCode jumpKey;


private bool isJumping = false;
private float timeInAir = 0.0f;

private void Awake()
{
    charController = GetComponent<CharacterController>();
}

private void Update()
{
    PlayerMovement();
}

private void PlayerMovement()
{
    float forwardInput = Input.GetAxis(verticalInputName);
    float rightInput = Input.GetAxis(horizontalInputName);

    Vector3 forwardMovement = transform.forward * forwardInput;
    Vector3 rightMovement = transform.right * rightInput;
    Vector3 horizMovement = (forwardMovement+rightMovement) * movementSpeed;

    float jumpVelocity = JumpInput();

    if (isJumping)
    {
        Vector3 vertMovement = Vector3.up * jumpVelocity * jumpMultiplier;
        charController.Move((horizMovement + vertMovement) * Time.deltaTime) 
    } 
    else
    {
        charController.SimpleMove(horizMovement);
    }
}

private float JumpInput()
{
    float jumpVelocity = 0f;

    if (Input.GetKeyDown(jumpKey) && !isJumping)
    {
        isJumping = true;
        charController.slopeLimit = 90.0f;
        timeInAir = 0f;
    }

    if (isJumping){
        if (timeInAir == 0f || 
               (!charController.isGrounded 
                && charController.collisionFlags != CollisionFlags.Above))
        {
            jumpVelocity = jumpFallOff.Evaluate(timeInAir);
            timeInAir += Time.deltaTime;
        } 
        else
        {
            ifJumping = false;
        }
    }

    return jumpVelocity;
}
