Unity：如何使用Vector3.Lerp函数一个接一个地创建和扩展100个多维数据集

Question

我如何使用Vector3.Lerp函数一个接一个地创建和扩展100个多维数据集。我需要依赖持续时间变量。我需要一种有效的方法。

Answer 1

尽管您的问题含糊不清：

例如使用Coroutine，例如

// Adjust these in the Inspector
[SerilaizeField] private Vector3 targetScale = Vector3.one;
[SerilaizeField] private Vector3 startScale = Vector3.zero;
[SerilaizeField] private float durationPerCube = 1f;
[SerilaizeField] private Transform[] cubes;

private IEnumerator ScaleUpRoutine()
{
    if(cubes.Length == 0) yield break;

    foreach(var cube in cubes)
    {
        var timePassed = 0f;
        while(timePassed < durationPerCube)
        {
            var factor = timePassed / duration;
            // optional easing-in and -out
            //factor = Mathf.SmoothStep(0, 1, factor);

            cube.localScale = Vector3.Lerp(startScale, targetScale, factor);

            timePassed += Time.deltaTime;
            yield return null;
        }

        // just to be sure set a hard value
        cube.localScale = targetScale;
    }
}

您可以随时通过StartCoroutine启动它，例如

private void Start()
{
    StartCoroutine(ScaleUpRoutine);
}

---

如果您希望基于整体持续时间，可以这样做

// Adjust this in the Inspector
[SerilaizeField] private float overallDuration = 2f;

private IEnumerator ScaleUpRoutine()
{
    if(cubes.Length == 0) yield break;

    var durationPerCube = overallDuration / cubes.Length;

    ...

[请记住，尽管yield return null;当前每个立方体等待至少一帧，所以如果您的overallDuration非常小（<100帧），则可能不准确。在这种情况下，您可能需要添加StopWatch，以便仅在某个实时阈值之后才StopWatch帧，例如

yield return
