How do I prevent creating multiple instances of the same scene when reloading a scene?
public class Canvas_Control : MonoBehaviour {
private static Canvas_Control canvas_control_instance;
void Awake()
{
DontDestroyOnLoad(this.gameObject);
if (canvas_control_instance == null) {
canvas_control_instance = this;
} else {
Destroy(gameObject);
}
}
public void Retry() {
print("retry pressed");
print("Before: " + SceneManager.sceneCount);
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex, LoadSceneMode.Single);
print("After load: " + SceneManager.sceneCount);
}
// The above prints Before: 1 and After load: 2
public void Next() {
print("next pressed");
// do stuff
}
// Now Next() will be called twice for each currently loaded scene,
// but I'd like it to be called only once.
}
This problem was solved after realizing that other scripts were adding multiple listeners to the same button.
