c# - 尝试在半随机位置一遍又一遍地生成预制件

问题描述

所以我编写了这段代码，试图开始制作一个脚本，在我的场景中随机生成灌木对象，但是在运行时它只会产生第一个灌木。这是代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class BushSpawner : MonoBehaviour
{

    public GameObject bush;
    private float x = 0f;
    private float y = -.47f;
    private float z = 0f;
    private int bushCount = 0;
    private Vector3 origPos;
    private bool xPlus = false;
    private bool xMinus = false;
    private bool zPlus = false;
    private bool zMinus = false;
    // Use this for initialization
    void Start()
    {
        SpawnBushes();
    }

    // Update is called once per frame
    void Update()
    {

    }

    void SpawnBushes()
    {
        Vector3 startPos = new Vector3(x, y, z);
        Instantiate(bush, startPos, Quaternion.identity);
        bushCount += 1;
        while (bushCount < 100)
        {
            Vector3 checkPos = new Vector3(x, y, z);
            Collider[] intersecting = Physics.OverlapSphere(checkPos, 1f);
            if (intersecting.Length == 0)
            {
                //code to run if nothing is intersecting as the length is 0
                Instantiate(bush, checkPos, Quaternion.identity);
                bushCount += 1;
            }
            else
            {
                //code to run if something is intersecting it
                RollPos();
            }
        }
    }
    void RollPos()
    {
        if (xPlus == true
            && xMinus == true
            && zPlus == true
            && zMinus == true)
        {
            int newRoll = Random.Range(1, 4);
            if (newRoll == 1)
            {
                x += 10f;
            }
            else if (newRoll == 2)
            {
                x -= 10f;
            }
            else if (newRoll == 3)
            {
                z += 10f;
            }
            else if (newRoll == 4)
            {
                z -= 10f;
            }
            xPlus = false;
            xMinus = false;
            zPlus = false;
            zMinus = false;
        }
        else
        {
            int roll = Random.Range(1, 4);
            if (roll == 1)
            {
                if (xPlus == false)
                {
                    x += 2f;
                    xPlus = true;
                }
                else
                {
                    RollPos();
                }
            }
            if (roll == 2)
            {
                if (xMinus == false)
                {
                    x -= 2f;
                    xMinus = true;
                }
                else
                {
                    RollPos();
                }
            }
            if (roll == 3)
            {
                if (zPlus == false)
                {
                    z += 2f;
                    zPlus = true;
                }
                else
                {
                    RollPos();
                }
            }
            if (roll == 4)
            {
                if (zMinus == false)
                {
                    z -= 2f;
                    zMinus = true;
                }
                else
                {
                    RollPos();
                }
            }
        }
    }
}

我尝试将 SpawnBushes 放入 Update 以在 bool 为真时运行，然后在 SpawnBushes 完成时使其为假，但这会创建第一个灌木，然后在它旁边的一个随机位置创建 99 个其他灌木。

如果有人能指出我正确的方向或告诉我我完全不在基地，我将非常感激！
