title: Unity 2D SetActive() is not working
body: <p>Here I used SetActive(true) to enable my gameObject but it is not working. I tried using various functions and objects that can enable my gameObj as can be seen in code. But nothing is working. Though when I set setActive(false), it works but that's not incase of setActive(true). I don't know the reason. Can anyone help me please? By the way I'm using Unity 4.3.4 version.</p>
  
  <pre><code>if (paddle.life == 1) {  
                  GameObject life_2 = GameObject.Find ("life2");
                  GameObject lost = GameObject.Find("lostlife");
                  life_2.SetActive (false);
                  lost.SetActive(true);
                  //lost.active = true;
                  //lost.renderer.enabled = true;(why null ref)
  
                  //after some secs disable the message
                  //Destroy(lost, 4);
              }
