在 java swing 中为 2d runner 游戏创建关卡

Question

I'm making a 2D runner game, I made my frames with

public class MainMenu2 {
    MainMenu2() throws IOException{
        JFrame Main_Menu = new JFrame("Main Menu");
        Main_Menu.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        final int widthScreen = screenSize.width;
        final int heightScreen = screenSize.height;

every time I created a class I made the JFrames like that every single time, without re-calling the class or whatever. I completed the menu with buttons that connect to other classes but I need to make a level now. It consists on a player moving right,left and up, collisions with platforms and enemies. Kinda like super mario. I'm a beginner in Java so I haven't found any examples that follow my structure, since they all base off from 1 JFrame. I don't know how to make a tile and connect it to a class' JFrame. I'm lost I need help, thank you.

Sound like you're confused in swing hierarchy.

You can use Jpanel in which You can set All tiles and then set Jpanel into Jframe.
In short from child to parent :: Tiles --> Jpanel --> Jframe. (Refer the one simple example : https://coderanch.com/t/633503/java/Tiled-Based-Map-Game-Java ).
