Using Sample

public class YourScript : MonoBehaviour
{
    private ObjectPool objectPool;

    private void Start()
    {
        objectPool = GetComponent<ObjectPool>();
    }

    private void SpawnObjectFromPool()
    {
        GameObject newObj = objectPool.GetPooledObject();
        // 가져온 오브젝트를 사용 (위치 설정 등)
        newObj.transform.position = Vector3.zero;
    }

    private void ReturnObjectToPool(GameObject obj)
    {
        objectPool.ReturnObjectToPool(obj);
    }
}
