为什么我收到错误“ObjectPoolingManager.Instance”由于其保护级别而无法访问？

Question

My player script

Error CS0122: 'ObjectPoolingManager.Instance' is inaccessible due to its protection level

Code:

// Update is called once per frame
void Update () 
{
    if (Input.GetMouseButtonDown(0)) 
    {
        ObjectPoolingManager.Instance.GetBullet ();

        GameObject bulletObject = Instantiate (bulletPrefab);
        bulletObject.transform.position = playerCamera.transform.position + playerCamera.transform.forward;
        bulletObject.transform.forward = playerCamera.transform.forward;
    }
}

In your class declaration, you must have made it Internal class ObjectPoolingManager() You can make it accessible by changing it to Public class ObjectPoolingManager()
