如何在动画播放时延迟统一运动

Question

我在 Unity 2018.4 中很难延迟我的角色的移动，我怀疑这更多的只是我的代码的问题而不是 unity。

编辑： 我希望能够按住右箭头键，让角色不动 415 毫秒，然后能够移动 580 毫秒，之后他不能移动 350 毫秒（让动画完成播放）

我尝试在 IE 分子中使用倒计时等待然后调用我的移动函数，但这导致我的角色在动画播放后没有移动。

//What makes the character move, works fine if executed on its own in update
private void ExecuteMovement(float dir)
    {
        currentPosition = transform.position;
        currentPosition.x += dir * Time.deltaTime * speed;
        transform.position = currentPosition;
    }

//Trying to use waitforseconds to delay the execution while the animation plays
private IEnumerator Movement(float dir)
    {
        yield return new WaitForSeconds(0.5f);

        ExecuteMovement(dir);
    }

void Update()
    {
        if (0 > Input.GetAxis("Horizontal"))
        {
            //This is to flip image
            transform.eulerAngles = new Vector3(0, 180, 0);

            //starts animation
            animator.SetBool("isSkipping", true);

            //calls the movement function with the direction to move in
            Movement(Input.GetAxis("Horizontal"));

        }

        else if (0 < Input.GetAxis("Horizontal"))
        {
            //This is to flip image
            transform.eulerAngles = new Vector3(0, 0, 0);

            //starts animation
            animator.SetBool("isSkipping", true);

            //calls the movement function with the direction to move in
            Movement(Input.GetAxis("Horizontal"));

        }
    }

我很乐意尝试任何延迟角色移动的替代方法。动画显示角色冲上去跳跃，然后跳跃。我只想在它在空中时移动，这大约是动画的半秒。

在更新中使用计时器怎么样？

float timer = 0f;
void Update()
{
    var dir = Input.GetAxis("Horizontal");
    if (0 > dir)
    {
        //This is to flip image
        transform.eulerAngles = new Vector3(0, 180, 0);

        //starts animation
        animator.SetBool("isSkipping", true);

        //calls the movement function with the direction to move in
        timer +=Time.deltaTime;
        if(timer >= 0.5){
           ExecuteMovement(dir);
           timer -=0.5f;
        }
        //Movement(Input.GetAxis("Horizontal"));

    }

    else if (0 < dir)
    {
        //This is to flip image
        transform.eulerAngles = new Vector3(0, 0, 0);

        //starts animation
        animator.SetBool("isSkipping", true);

        //calls the movement function with the direction to move in
        timer +=Time.deltaTime;
        if(timer >= 0.5){
           ExecuteMovement(dir);
           timer -=0.5f;
        }
        //Movement(Input.GetAxis("Horizontal"));

    }
}

在大量修改 Gray_Rhino 对这个问题的回答后，我发现了一种相当粗略的方法来完成这项工作。我设置了我的跳跃动画的 3 个阶段，当连续向一个方向移动时，计时器将检查它进入动画的距离并决定是否允许移动输入。动画结束或角色被告知向另一个方向移动后，计时器会重置。

bool facingRight;
    int jumpPhase = 1;
    float timer = 0f;
    float dir;
    void Update()
    {
        if (jumpPhase != 3)
        {
            dir = Input.GetAxis("Horizontal");
        }

        if (0 > dir || (jumpPhase == 3 && facingRight == true))
        {
            timer += Time.deltaTime;

            if (facingRight != true)
            {
                transform.eulerAngles = new Vector3(0, 180, 0);
                jumpPhase = 1;
                timer = 0f;
                facingRight = true;
            }

            else if (jumpPhase == 1)
            {
                //starts animation
                animator.SetBool("isSkipping", true);

                if (timer >= 0.415f)
                {
                    jumpPhase = 2;
                }
            }

            else if (jumpPhase == 2)
            {
                ExecuteMovement(dir);

                if (timer >= 0.995f)
                {
                    jumpPhase = 3;
                }
            }

            if (jumpPhase == 3)
            {
                if (timer >= 1.5f)
                {
                    jumpPhase = 1;
                    timer = 0f;
                }
            }

        }

        else if (0 < dir || (jumpPhase == 3 && facingRight != true))
        {
            timer += Time.deltaTime;            

            if (facingRight == true)
            {                
                transform.eulerAngles = new Vector3(0, 0, 0);
                jumpPhase = 1;
                timer = 0f;
                facingRight = false;
            }

            else if (jumpPhase == 1)
            {
                //starts animation
                animator.SetBool("isSkipping", true);

                if (timer >= 0.415f)
                {
                    jumpPhase = 2;
                }
            }

            else if (jumpPhase == 2)
            {
                ExecuteMovement(dir);

                if (timer >= 0.995f)
                {
                    jumpPhase = 3;
                }
            }

            if (jumpPhase == 3)
            {
                if (timer >= 1.5f)
                {
                    jumpPhase = 1;
                    timer = 0f;
                }
            }

        }
    }

您正试图像调用方法一样调用您的 IEnumerator。

相反，您必须将其作为 Coroutine using StartCoroutine

启动

StartCoroutine(Movement(Input.GetAxis("Horizontal")));

看到你的编辑

I want to be able to hold down the right arrow key, have the character not move for 415ms, then be able to move for 580ms, after which he cannot move for 350ms (to let the animation finish playing)

到现在为止，既然你想要一个连续的运动但仍然完全控制速度，我会把它保持在 Update 并且只使用协程来控制一个标志。协程仍然比 read/write 和维护更好。（现在也可以在空中切换方向了。。不知道你要不要）：

// control the ability to move with a simple flag
// instead of various states
public bool canMove;

// check if a jumping is already being animated/executed 
// -> disallow a new jumping animation until it is finished
private bool canJump = true;

private void Update()
{
    // avoid repeated API calls
    var input = Input.GetAxis("Horizontal");

    if (input < 0)
    {
        //This is to flip image
        transform.eulerAngles = new Vector3(0, 180, 0);

        if(canJump)
        {
            //starts the movement
            StartCoroutine(Jump());
        }
    }
    else if (input > 0)
    {
        //This is to flip image
        transform.eulerAngles = new Vector3(0, 0, 0);

        if(canJump)
        {
            //starts the movement
            StartCoroutine(Jump());
        }
    }

    // if can not move do nothing else
    if(!canMove) return;

    // execute the movement
    transform.position += Vector3.right * input * speed * Time.deltaTime;
}

private IEnumerator Jump()
{
    // disable jumping
    canJump = false;

    // disable move during animation
    canMove = false;

    //starts animation
    animator.SetBool("isSkipping", true);

    // not move for 415ms
    yield return new WaitForSeconds(0.415f);

    // enable move
    canMove = true;

    // be able to move for 580ms
    yield return new WaitForSeconds(0.580f);

    // disable move
    canMove = false;

    // cannot move for 350ms during end of animation
    yield return new WaitForSeconds(0.350f);

    // enable move again
    canMove = true;

    // re-enable jumping
    canJump = true;
}
