Collision Detection goes to Win Screen

When my character hits the door I want him to go to win Screen but I have no idea how. I copied and pasted a code from my Title screen that when I press Play it goes into the game. But I don't know how to track "if character hits door go to next screen".

Here is my code:

Here is my backdoor with a rigid body





Here is my Win Screen

 

The method for loading new scenes in Unity is Application.LoadLevel (there are however other loading methods that I wont get into here). To use Application.LoadLevel you need to supply it with ether a int or a string; where the int would be the desired scenes number in the build settings and the string would be the desired scenes name. Like so:

Code (csharp):

1.  
2. Application.LoadLevel(0); //loads the first scene
3. Application.LoadLevel("MainMenu"); //loads the scene named "MainMenu"
4.  

I should note that the desired scene must be added to the list of scenes in the build settings before you are able to load it.
