Unity Instantiate Game Mechanic仅在C＃的一半时间内工作

Question

我正在尝试为iPhone制作一款小游戏，这是一种简单的游戏机制，其中某些平台会在90 degrees中的-90 degrees，0 degrees或y rotation生成。

它应该在平台之间产生空间或间隙。

大约一半的时间。其中一半有空位而其他人没有空位。

这是我的脚本。你不需要重新输入整个东西。对不起，如果它马虎。

public class General : MonoBehaviour
{

    public int time;
    public int timeLev;
    public int speed = 7;
    public GameObject platformTypeOne;
    public float platPosx;
    public int ran;
    public float platLegnth; 

    public int[] platRotationSel = new int[] { 0, 90, -90};
    public int platRotation;

    void Start()
    {
        StartCoroutine("PlatSpawn");

    }

    void Update()
    {

        time = (int)(Time.time % 1000000f);

        speed = time / 3;
        platRotation = platRotationSel[Random.Range(0, 3)];
        Debug.Log(platRotation.ToString());

    }

    IEnumerator PlatSpawn()
    {
        while (true)
        {
            if (platRotation == 90 || platRotation == -90)
            {
                platLegnth = 2.5f;
            }
            else
            {
                platLegnth = 5f;
            }
            ran = Random.Range(0, 4);
            platPosx = platPosx + platformTypeOne.transform.position.x + platLegnth;
            Instantiate(platformTypeOne, new Vector3(platPosx, 0, 0), transform.rotation);
            yield return new WaitForSeconds(0.5f);
            if (platRotation == 90 || platRotation == -90)
            {
                platLegnth = 2.5f;
            }
            else
            {
                platLegnth = 5f;
            }
            ran = Random.Range(0, 4);
            platPosx = platPosx + platformTypeOne.transform.position.x + platLegnth;
            Instantiate(platformTypeOne, new Vector3(platPosx, 0, 0), Quaternion.Euler(new Vector3(0, platRotation, 0)));
            yield return new WaitForSeconds(0.5f);
        }


    }
