平滑地看不同的物体答案

【问题标题】：Smoothly LookAt different object平滑地看不同的物体

【问题描述】：

由于图片描绘了我的相机在路径上移动，我想平滑地查看路径的不同对象。目前我已经尝试过

trasnform.LooAt(activePath.gameObject.transform);

但它会产生生涩的结果。对象突然用混蛋看下一个对象！如何避免它。我搜索并找到了这个解决方案，但它也不起作用

var targetRotation = Quaternion.LookRotation(activePath.gameObject.transform.position - transform.position);
        transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime);

【解决方案1】：

void SmoothLookAt(Vector3 newDirection){ transform.rotation = Quaternion.Lerp(transform.rotation, Quaternion.LookRotation(newDirection), Time.deltaTime); }

将新看目标的Vector3位置传递给该方法，它会顺利看目标。

例如SmoothLookAt(activePath.gameObject.transform)

尝试将乘数添加到Time.deltaTime 以减慢移动速度以查明您的问题。我担心还有其他脚本会导致问题。您可能需要发布更多脚本示例
实际上我正在使用获得 spl 格式样条线的 megaShape 包，然后我将我的相机一个接一个地移动到这些样条线上。更多stackoverflow.com/questions/37249480/…

这是一种进行流畅翻译的方法。参数是

要翻译的对象变换，
最终位置和
看看变换

private const float ANIMATION_DURATION_IN_SECONDS = 5f;

private IEnumerator SmoothTranslation(Transform startTransform, Vector3 finalPosition, Transform lookAtTransform){
        float currentDelta = 0;

        // Store initial values, because startTransform is passed by reference
        var startPosition = startTransform.position;
        var startRotation = startTransform.rotation;

        while (currentDelta <= 1f) {
            currentDelta += Time.deltaTime / ANIMATION_DURATION_IN_SECONDS;

            transform.position = Vector3.Lerp(startPosition, finalPosition, currentDelta);

            if (lookAtTransform != null) {
                // HACK Trick: 
                // We want to rotate the camera transform at 'lookAtTransform', so we do that.
                // On every frame we rotate the camera to that direction. And to have a smooth effect we use lerp.
                // The trick is even when we know where to rotate the camera, we are going to override the rotation 
                // change caused by `transform.lookAt` with the rotation given by the lerp operation. 
                transform.LookAt(lookAtTransform);
                transform.rotation = Quaternion.Lerp(startRotation, transform.rotation, currentDelta);
            }
            else {
                Debug.LogWarning("CameraZoomInOut: There is no rotation data defined!");
                transform.rotation = originalCameraRotation;
            }

            yield return null;
        }

    }
