c# - 试图在我的游戏中实现缩放功能，但它不会取消缩放

Question

您好，我试图在我的游戏中实现缩放功能，但是当我释放缩放键时，它不会让我的 FOV 回到原来的位置

    float startingFOV = playerCamera.fieldOfView;
    float timeElapsed = 0;

    while(timeElapsed < timeToZoom)
    {
        playerCamera.fieldOfView = Mathf.Lerp(startingFOV, targetFOV, timeElapsed / timeToZoom);
        timeElapsed += Time.deltaTime;
        yield return null;
    }

    playerCamera.fieldOfView = targetFOV;
    zoomRoutine = null;
}

您的代码不起作用，因为您的第二个if语句在第一个if语句内。
您的代码应如下所示：

private void HandleZoom()
{
    if (Input.GetKeyDown(zoomKey))
    {
        if (zoomRoutine != null)
        {
            StopCoroutine(zoomRoutine);
            zoomRoutine = null;
        }

        zoomRoutine = StartCoroutine(toggleZoom(true));
    }

    if (Input.GetKeyUp(zoomKey))
    {
        if (zoomRoutine != null)
        {
            StopCoroutine(zoomRoutine);
            zoomRoutine = null;
        }

        zoomRoutine = StartCoroutine(toggleZoom(false));
    }
}
