since my game is nearing completion now, i wanted to implement a sort of "main menu" where some basic info is displayed, along with a button that, when pressed, teleports you into the actual game world.
for this, i set up a second world called "Hauptmenü" (english: main menu).
The content of that class:
basically, it just sets the image up to scale properly with the game, and places a start button in the bottom right.
the code of the start button:
with this, i wanted to achieve that when pressed, as i said, it will teleport the player into the actual gameworld called "MyWorld" per default.
since i had issues making the main menu display before the actual world displays, i set something up in my MyWorld.class to make the main menu show up first.
The contents of that:
the idea was that the int "menu" is set to 1 after opening the main menu, so thhat when i close it by clicking on the start button, it wont open the menu again since its on 1, meaning that the Greenfoot.setWorld function wont run
I realized though that since i set up a "Greenfoot.setWorld(new MyWorld());" in my start button class, the entire MyWorld class is run through again, creating an endless cycle that results in the main menu closing when u click the start button, then displaying the game world for about a frame and then opening the main menu again.
I am struggling to find a workaround for this, so if any of you have an idea, i would appreciate the help ^^
