Unity 2d Enemy Spawning 不符合正确条件

Question

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

public class EnemySpawner : MonoBehaviour
{
    public GameObject[] enemyPrefabArray;
    public GameObject player;
    [SerializeField] MapGenerator mapGeneratorScript;

    void OnEnable() => mapGeneratorScript.OnGeneratedMap += SpawnMobs;

    void OnDisable() => mapGeneratorScript.OnGeneratedMap -= SpawnMobs;

    void SpawnMobs()
    {
        StartCoroutine(SpawnEnemies(enemyPrefabArray[0], 0.1f, 0.2f, 20, 6));
    }

    IEnumerator SpawnEnemies(GameObject enemyPrefab, float minInterval, float maxInterval, int maxEnemyCount, int withinRangeOfPlayer)
    {
        int numOfEnemies = 0;

        while (numOfEnemies < maxEnemyCount)
        {
            Vector3 playerPos = player.transform.position;
            yield return new WaitForSeconds(Random.Range(minInterval, maxInterval));

            int randomXCoord = Mathf.RoundToInt(playerPos.x) + Random.Range(-withinRangeOfPlayer, withinRangeOfPlayer + 1);
            int randomYCoord = Mathf.RoundToInt(playerPos.y) + Random.Range(-withinRangeOfPlayer, withinRangeOfPlayer + 1);

            if (randomXCoord >= 0 && randomXCoord < mapGeneratorScript.map.GetLength(0) && randomYCoord >= 0 && randomYCoord < mapGeneratorScript.map.GetLength(0))
            {
                // Avoiding spawns in water tile
                bool isWaterTile = mapGeneratorScript.map[randomXCoord, randomYCoord] == 1;
                if (!isWaterTile)
                {
                    Instantiate(enemyPrefab, new Vector3(randomXCoord, randomYCoord, 0), Quaternion.identity);
                    numOfEnemies++;
                    Debug.Log($"Player X: {playerPos.x} Player Y: {playerPos.y}, X: {randomXCoord} Y: {randomYCoord}, {mapGeneratorScript.map[randomXCoord, randomYCoord]}");
                }
                else
                {
                    Debug.Log("Avoided Spawn on Water");
                }
            }
        }
    }
}

我的代码问题是，当我在游戏中生成后保持静止时，敌人会正确生成，敌人生成在 1 个瓷砖中，也避免在水瓷砖中生成，但是每当我开始在地图上移动时，敌人的生成打破它们产生偏离中心或在 2 个或更多瓷砖之间，敌人也会在水瓷砖中产生。调试控制台中的坐标和值与地图中的实际预制件不匹配，我很困惑为什么会这样？

这也是我生成后不动时敌人生成的图片 这是我产卵后四处走动的时候（顺便说一句，如果我停止移动，错误就不会自行修复）

玩家的位置在敌方生成协程运行的同时不断变化。当玩家移动时，新生成位置的坐标计算不准确。

我更新了 Vector3、StartCoroutine 和 IEnumerator。运行它，看看它是否有效

void SpawnMobs()
{
    Vector3 currentPlayerPosition = player.transform.position;
    StartCoroutine(SpawnEnemies(enemyPrefabArray[0], 0.1f, 0.2f, 20, 6, currentPlayerPosition));
}

IEnumerator SpawnEnemies(GameObject enemyPrefab, float minInterval, float maxInterval, int maxEnemyCount, int withinRangeOfPlayer, Vector3 currentPlayerPosition)
{
    int numOfEnemies = 0;

    while (numOfEnemies < maxEnemyCount)
    {
        yield return new WaitForSeconds(Random.Range(minInterval, maxInterval));

        int randomXCoord = Mathf.RoundToInt(currentPlayerPosition.x) + Random.Range(-withinRangeOfPlayer, withinRangeOfPlayer + 1);
        int randomYCoord = Mathf.RoundToInt(currentPlayerPosition.y) + Random.Range(-withinRangeOfPlayer, withinRangeOfPlayer + 1);

        if (randomXCoord >= 0 && randomXCoord < mapGeneratorScript.map.GetLength(0) && randomYCoord >= 0 && randomYCoord < mapGeneratorScript.map.GetLength(0))
        {
            // Avoiding spawns in water tile
            bool isWaterTile = mapGeneratorScript.map[randomXCoord, randomYCoord] == 1;
            if (!isWaterTile)
            {
                Instantiate(enemyPrefab, new Vector3(randomXCoord, randomYCoord, 0), Quaternion.identity);
                numOfEnemies++;
                Debug.Log($"Player X: {currentPlayerPosition.x} Player Y: {currentPlayerPosition.y}, X: {randomXCoord} Y: {randomYCoord}, {mapGeneratorScript.map[randomXCoord, randomYCoord]}");
            }
            else
            {
                Debug.Log("Avoided Spawn on Water");
            }
        }
    }
}
