Hello everyone. I’m trying to develop a script that add points when the player touch an object. I’m following the official unity tutorial but it seems to have problems. When I’m in the unity platform I always have this error:

 error CS0122: `GameController.AddScore(int)' is inaccessible due to its protection level

Here is the two scripts used:

DestroyByContacts (applied to object that need to be destroyed after collision and add point:

using UnityEngine;
using System.Collections;

public class DestroyByContact : MonoBehaviour {

	public int scoreValue;
	private GameController gameController;

	void Start() {
		GameObject gameControllerObject = GameObject.FindWithTag ("GameController");
		if (gameControllerObject != null) {
			gameController = gameControllerObject.GetComponent<GameController>();
		}
		if (gameController == null) {
			Debug.Log("Cannot find 'GameController' script");
		}
	}

	void OnCollisionEnter2D(Collision2D coll)
	{
		if (coll.gameObject.tag == "Player")
		{
			Destroy(this.gameObject);
			gameController.AddScore(scoreValue);
		}

	}
}

GameController ( applied to the GameController Object of the scene:

using UnityEngine;
using System.Collections;

public class GameController : MonoBehaviour {

	public GUIText scoreText;
	private int score;

	void Start ()
	{
		score = 0;
		UpdateScore ();
	}

	void UpdateScore() 
	{
		scoreText.text = "Score: " + score;
	}

	void AddScore( int newScoreValue )
	{
		score += newScoreValue;
		UpdateScore ();
	}
}

Please help! I’m becoming crazy! I don’t know how to adjust this error.

Pretty much as the error says, your AddScore method is not publicly accessible. Change

void AddScore( int newScoreValue)

To

public void AddScore(int newScoreValue)
