I’m making the main menu for a game based on a YouTube video. After the narrator wrote scripts for the buttons, he began to add them to these buttons. For some reason I cannot do this. I cannot add a start game or an exit. I just don’t have it. The video displays a context menu and the last line titled NewBehaviourScript . I have not it.

Tell me how to add it? I have already searched all YouTube, Google and the unit website, but I could not find a solution to my problem. The script is written in C # .

In the UI buttons, you can assign the OnClick event.

In it you need to select the object on which the script handler is hanging (this can be the button itself, if desired), and then on the right side of this drop-down list select the very script and the desired method from the same script:

Everything.

Moreover, the methods must be public . Example:

using UnityEngine;
public class SwitchCameras: MonoBehaviour {
  private void Start () {
  }
  public void Switch () {
    Debug.Log ("Some method was called here");
  }
}

When a method with arguments appears, you can add this parameter to the button’s OnClick event:
