Switching from menu to game


#1

Hi ! So, I’m trying to make a game for a school project and I’ve only made a menu so far, anyway I’d like some help on switching from the menu screen to the game screen. Right now, when I click on my button, nothing really happens( except that it won’t change color anymore I d’ont know why), basically, what I did was declaring an integer called Screen, I’d give it the value 0 and in the draw , in the draw if screen’s value is 0, then it displays the menu, if it’s one, it should display the game. So I made it so that when clicked on the button, screen changes to 1. But nothing happens.
Sorry there’s some french in my code but can you help me? Thank you! and sorry for my English.

      screen = 1;
   
  } 
}

The problem isn’t that it’s not working. It does switch to drawing the game screen. The trouble is that the gameScreen() function doesn’t DO anything!

If you change it to this, you will see that it is changing:

void gameScreen(){
  background(0);
  fill(255);
  text("gameScreen() running!", 20, 20);
}
