Why does a click in one scene also work in the next?

Question

Unity

Hello colleagues. I understand with Unity3d, makes a 2D game in which you need to click on a button and go to another scene.
In the first scene I do

button.onClick.AddListener(SomeHandler); 
void SomeHandler() { 
    SceneManager.LoadScene ("Result"); return; 
}

At the same time, on the second stage in the same place there is a button that immediately works when entering the stage. How to avoid such behavior?

Answer 1

I doubt that the new scene button works. Check if the handler is added twice to the button of the old scene.
