why does if statement ignore bool?

Hey guys i am trying to make a background in a 2D game which slowly scrolls but i am making a transition to enter a new world but it seems like unity just ignores my bool in the if statement?? anyone know how come?

the script is attached to two different pictures which then scrolls

	float moveSpeed = -0.02f;
	float World2 = 20f;
	float maxHeight = 0f;
	bool transition = false;

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {

		transform.Translate (0, moveSpeed, 0);

		maxHeight = renderer.bounds.size.y;

		Vector3 pos = transform.position;

		if (-maxHeight >= pos.y) {
			pos.y = +maxHeight + moveSpeed;
			transform.position = pos;
		}

		if (Score.score >= World2) {

			if (pos.y >= 11.42f && transition == false){
					Debug.Log ("HALLLO!!!!!");
					gameObject.GetComponent<SpriteRenderer> ().sprite = Resources.Load("World2Trans", typeof(Sprite)) as Sprite;
					
					Vector3 scale = transform.localScale;
					scale.y = 1.01f;
					transform.localScale = scale;

				transition = true;
			}

			if (pos.y >= 11.42f && transition == true){
				gameObject.GetComponent<SpriteRenderer> ().sprite = Resources.Load("World2", typeof (Sprite)) as Sprite;
			}
		}



	}
}

The “&&” operator short-circuits. That means that if the first expression is False, it does not evaluate the second. Same happens to “||” (if first expression is True, second is not evaluated). More here.

If you really want to evaluate both expressions, you can use &. Although, that makes no sense in your case (it’s better suited if your second condition also runs some code you want to run regardless of the logical outcome).

Also, I’d refactor your code like this:

    if (Score.score >= World2 && pos.y >= 11.42f)
    {
                if (!transition)
                {
                        Debug.Log ("HALLLO!!!!!");
                        gameObject.GetComponent<SpriteRenderer> ().sprite = Resources.Load("World2Trans", typeof(Sprite)) as Sprite;
     
                        Vector3 scale = transform.localScale;
                        scale.y = 1.01f;
                        transform.localScale = scale;
     
                    transition = true;
                }
                else
                {
                    gameObject.GetComponent<SpriteRenderer> ().sprite = Resources.Load("World2", typeof (Sprite)) as Sprite;
                }
}

Also, you have no code that resets “transition” once it’s been set to true. Maybe you should look into that, too.
