Loading new level with RaycastHit

Questions & Answers

What am I missing?

 if (Input.GetMouseButtonDown (0)) {

		Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
		RaycastHit hit = new RaycastHit();

		if (Physics.Raycast(ray, out hit, 20)) {
		
			if (hit.collider.name == "collider0")
					Application.LoadLevel ("level_1");
	
			if (hit.collider.name == "collider1")
					Application.LoadLevel ("level_2");
	
			if (hit.collider.name == "collider2")
					Application.LoadLevel ("level_3");
	}

}

I just want, when I press the “button” the new level to load.

why dont you use OnGUI function and create a button for level selection. you don’t need to raycast for this.

instead of

  if (hit.collider.name == "collider0")
                    Application.LoadLevel ("level_1");

you can write

   if (GUI.Button (Rect (20,70,80,20), "level1button")) {
   Application.LoadLevel ("level_1");
