Problem with button On Click

Questions & Answers
1

I am using unity 4.6.3. I am new to unity so I watched several video tutorials on youtube all the step i did that was in tutorial. I tried everything but I can’t find solution of my problem.

In my project I created a scene “MainMenu” In this scene there are two buttons named “Start Game” & “Exit Game”.
There is an empty game object also with position (0,0,0) and add a script “mainMenuButtons” to it.

Here is my script “mainMenuButtons”

public class mainMenuButtons : MonoBehaviour {

void StartGame(){
	Application.LoadLevel (1);
}

void ExitGame(){
	Application.Quit ();
}

}

Now I want to assign on click event on “Start Game” buttons to this StartGame() function.
So I followed the steps click on StartButton.
Click on “+” sign below the On Click().
When I click “+” sign I show 3 items here is a screen shot

I draged an empty game object i.e. UIManager.
click on No Function and select a script “mainMenuButtons” but there is no StartGame() function or ExitGame() function.

Here is a screenshot

I found answer my self. This may help others who are new to unity3d.
Just add a public keyword.
by default the function in unity is private and if you declare a private function then the outside the unity inspector can’t use those function. so you need to assign a public function.

Here is my script and it works perfectly.

public class mainMenuButtons : MonoBehaviour {
 
public void StartGame(){
     Application.LoadLevel (1);
 }
 
 public void ExitGame(){
     Application.Quit ();
 }
