I have written a script card to spawn coin item. However, it only spawns correctly if the map is square. I have a round map, but it seems to spawn the same as a square map, which really doesn't work, because it will cause the coins to spawn outside the map. Anyone with any ideas please help me

[SerializeField] GameObject coinPrefab;
    [SerializeField] int coinsToSpawnCount;
    private void Start()
    {
        SpawnCoins();

    }


    public void SpawnCoins()
    {
        for (int i = 0; i < coinsToSpawnCount; i  )
        {
            GameObject temp = Instantiate(coinPrefab, transform);
            temp.transform.position = GetRandomPointInCollider(GetComponent<Collider>());
        }

    }

   
 
    Vector3 GetRandomPointInCollider(Collider collider)
    {
        Vector3 point = new Vector3(
            Random.Range(collider.bounds.min.x, collider.bounds.max.x),
            Random.Range(collider.bounds.min.y, collider.bounds.max.y),
            Random.Range(collider.bounds.min.z, collider.bounds.max.z)
            );
        if (point != collider.ClosestPoint(point))
        {
            point = GetRandomPointInCollider(collider);
        }
        point.y = 1f;
        return point;
    }

This determines spawn point to be inside a cube limited by collider bounds:

Vector3 point = new Vector3(
            Random.Range(collider.bounds.min.x, collider.bounds.max.x),
            Random.Range(collider.bounds.min.y, collider.bounds.max.y),
            Random.Range(collider.bounds.min.z, collider.bounds.max.z)
            );

Just try spawning randomly inside a unit sphere with a given radius instead:

Vector3 point = Random.insideUnitSphere * radius;
