Question

我的角色控制器的接地状态在似乎每一帧都不断闪烁。据我所知，应该检查玩家是否通过player.isGrounded接地，但是还有其他方面正在将其向上移动。

using UnityEngine;

public class PlayerCharacterController: MonoBehaviour {

    static Animator anim;

    public bool walking;

    public GameObject playerModel, Hero;
    //Transforms
    public Transform playerCam, character, centerPoint;

    private Vector3 moveDirection;

    CharacterController player;

    public float mouseYPosition = 1f;

    public float Sensitivity = 10f;
    //Mouse Zoom

    public float zoomSpeed = 2;
    //Clamping Zoom
    public float zoomMin = -2f;
    public float zoomMax = -10f;
    public float rotationSpeed = 5f;
    //Move Front Back left & Right
    private float moveFB, moveLR;   
    //Movement Speed

    //Multiple Jumps
    int jumpTimes;
    //To use with Dialogue Manager
    public DialogueManager DiagM;

    public AudioClip jumpSound;
    public AudioClip HurtSound;
    public AudioClip PunchSound;

    AudioSource audioSource;

    public float knockBackForce;
    public float knockBackTime;
    private float knockBackCounter;


    // Use this for initialization
    void Start ()   
    {
        //character controller
        player = GameObject.Find("Player").GetComponent<CharacterController> ();

        StartCoroutine(MyCoroutine(character));

        anim = GetComponent<Animator>();

        //mouse zoom
        zoom = -3;  
        centerPoint.transform.position = playerCam.transform.position;
        centerPoint.transform.parent = null;
        audioSource = GetComponent<AudioSource>();
    }

    IEnumerator MyCoroutine (Transform character)
    {
        if (player.isGrounded == true)

        {
        anim.SetBool("isFalling",false);
        //anim.SetBool("isIdling", true);
        yield return new WaitForSeconds(0);
        }

    }
    // Update is called once per frame

    void Update ()
    {        
        //Mouse Zoom Input
        zoom += Input.GetAxis ("Mouse ScrollWheel") * zoomSpeed;

        if (zoom > zoomMin)
            zoom = zoomMin;
        if (zoom < zoomMax)
            zoom = zoomMax;

        //Mouse Camera Input
        playerCam.transform.localPosition = new Vector3 (0, 0, zoom);

        //Mouse Rotation

        rotX += Input.GetAxis ("Mouse X") * Sensitivity;
        rotY -= Input.GetAxis ("Mouse Y") * Sensitivity;      

        //Clamp Camera
        rotY = Mathf.Clamp (rotY, -60f, 60f);
        playerCam.LookAt (centerPoint);
        centerPoint.localRotation = Quaternion.Euler (rotY, rotX, 0);

        //Movement Speed
        if (knockBackCounter <= 0)
        {   
            moveDirection = (transform.forward * Input.GetAxis("Vertical")) + (transform.right * Input.GetAxis("Horizontal"));
            moveDirection = moveDirection * Speed;
            moveDirection.y = verticalVelocity;

            player.Move(moveDirection * Time.deltaTime);



            //Movement Rotation

            centerPoint.position = new Vector3 (character.position.x, character.position.y + mouseYPosition, character.position.z);

            //knockback disable
            //Movement Input

            if (Input.GetAxis("Vertical") != 0 || Input.GetAxis("Horizontal") != 0)

            {
                transform.rotation = Quaternion.Euler(0f, centerPoint.rotation.eulerAngles.y, 0f);
                Quaternion turnAngle = Quaternion.LookRotation(new Vector3(moveDirection.x, 0f, moveDirection.z));
                playerModel.transform.rotation = Quaternion.Slerp(playerModel.transform.rotation, turnAngle, Time.deltaTime * rotationSpeed);

                if (player.isGrounded == true)
                {
                    anim.SetBool("isWalking", true);
                    anim.Play("Running");
                }
            }
            else 
            {
                StartCoroutine(MyCoroutine(character));
            }

            if (Input.GetButtonDown("LHand"))
            {
                audioSource.PlayOneShot(PunchSound, 1F);
                anim.Play("RPunch");
            }

            if (player.isGrounded == true)
            {
                jumpTimes = 0;
                //verticalVelocity = -Physics.gravity.y * Time.deltaTime;
                verticalVelocity = 0;
            }
            else
            {
                verticalVelocity += Physics.gravity.y * Time.deltaTime;
                anim.SetBool("isWalking", false);
                anim.SetBool("isFalling", true);
            }


            if (jumpTimes < 1)
            {
                if (Input.GetButtonDown("Jump"))
                {
                    verticalVelocity += jumpDist;
                    anim.Play("Jump");
                    audioSource.PlayOneShot(jumpSound, 1F);
                    jumpTimes += 1;
                }
            }
        }
        else
        {
            knockBackCounter -= Time.deltaTime;
        }
    }

    public void Knockback(Vector3 direction)
    {
        knockBackCounter = knockBackTime;
        anim.Play("Jump");
        audioSource.PlayOneShot(HurtSound, 50F);
        moveDirection = direction * knockBackForce;
        moveDirection.y = knockBackForce;
    }
}

看起来它与verticalVelocity行有关，但是到目前为止，我仅尝试将verticalVelocity = 0设置为有效，直到我实际移动了角色为止。我该怎么做才能停止闪烁？

Answer 1

根据您的评论。您不应该通过检查动画参数来确定播放器是否接地。最好的方法是使用RayCast（）。因此，您必须要做的事情：

创建一个名为Ground的图层，然后将所有平台添加到您的场景。
创建布尔变量

即

bool isGrounded;

创建一个函数来检查角色是否接地

类似的东西：

bool checkGrounded(){

    return Physics.Raycast(transform.position, Vector3.down, 2f, 1 << LayerMask.NameToLayer("Ground")));

}

在此answer中，您可以了解有关Raycast中涉及的参数

最后在更新中检查播放器是否接地

类似的东西：

void Update(){
    isGrounded = checkGrounded();
}

Answer 2

可能它已经解决了，但是原因是，如果您正在使用角色控制器，则应该一直对角色施加重力。

当角色与对象碰撞时，它实际上会进入该对象内部一点点，然后Unity将角色推回远离该对象的位置，直到不再接触该对象为止。此时，您的重力再次开始起作用，并重新开始循环。

您需要100％的时间施加重力，以产生足够的力量来“平衡”与地面的战斗。可以是较小的“重力”，例如1。不需要是您的重力变量。

此外，最重要的是，我想添加一个“土狼时间”，并使我的IsGrounded（）方法如下：

    public bool IsGrounded()
{
    return CoyoteTime < CoyoteTimeMax;
}

public void CoyoteControl()
{
    if (CharController.isGrounded)
    {
        CoyoteTime = 0;
    }
    else
    {
        CoyoteTime += Time.deltaTime;
    }
}

然后我在Update（）上调用CoyoteControl（），并且可以在需要时调用IsGrounded（）。在检查器上，我通常将CoyoteTimeMax设置为0.1，这样可以使跌落更加平滑。

统一的接地状态正在闪烁以显示角色。 .isGrounded被使用但仍然闪烁
