Question

好的我正在开发一款游戏，我正在努力解决为什么光滑的更新方法无法正常工作，基本上在我看到它工作的教程中，但在我看来它没有。我问你的管教程视频，没有人知道为什么会这样。所以任何帮助将不胜感激。这是我的代码：



package phex.launcher;

import static org.lwjgl.opengl.GL11.*;

import org.lwjgl.opengl.*;
import org.lwjgl.*;
import org.lwjgl.input.Keyboard;
import org.lwjgl.input.Mouse;
import org.newdawn.slick.GameContainer;
import org.newdawn.slick.Graphics;
import org.newdawn.slick.Image;
import org.newdawn.slick.SlickException;
import org.newdawn.slick.state.BasicGameState;
import org.newdawn.slick.state.StateBasedGame;


public class Phex extends BasicGameState{

    public static int screen;
    private Image tweet;
    private Image logo;
    private Image base;
    private Graphics g;
    private GameContainer gc;

    public Phex() throws SlickException
    {
        new LoginButton();
        try {
            Display.setDisplayMode(new DisplayMode(800, 650));
            Display.setTitle("Phex Launcher");
            Display.setResizable(true);
            Display.create();
        } catch (LWJGLException e) {
            e.printStackTrace();
            Display.destroy();
            System.exit(1);
        }

        init(gc, null);


        //Initialisation code(OpenGL)
        glMatrixMode(GL_PROJECTION);
        glLoadIdentity(); // Resets any previous projection matrices
        glOrtho(0, 800, 650, 0, 1, -1);
        glMatrixMode(GL_MODELVIEW);
        glEnable(GL_TEXTURE_2D);

        while(!Display.isCloseRequested())
        {
            //render
            render(gc, null, g);
            update(gc, null, 0);
        }
        Display.destroy();

    }   

    public static void main(String args[]) throws SlickException
    {
        new Phex();
    }
    public void init(GameContainer container, StateBasedGame game)
            throws SlickException {
        tweet = new Image("img/twitter-logo.png");
        logo = new Image("img/logo.png");
        base =  new Image("img/base-for-login.png");


    }
    public void render(GameContainer container, StateBasedGame game, Graphics g)
            throws SlickException {
        if(Keyboard.isKeyDown(Keyboard.KEY_ESCAPE))
        {
            Display.destroy();
            System.exit(0);
        }

        base.draw(0,0);
        logo.draw(50, 5);
        tweet.draw(200, 5);

        //screen renderer
        screen = 0;
        if(screen == 0)
        {

        }
        if(screen == 1)
        {

        }



        Display.update();
        Display.sync(60);

    }
    public void update(GameContainer container, StateBasedGame game, int delta)throws SlickException {
        int posx = Mouse.getX();
        int posy = Mouse.getY();

        if((posx>50 && posx<150)&&(posy>5 && posy<100))
        {
            System.out.println("in area");
            if(Mouse.isButtonDown(0))
            {
                Display.destroy();

            }
        }

    }
    @Override
    public int getID() {
        return 0;
    }
}

周六早餐时阅读这篇文章（即没有太多深度！）看起来你正在覆盖BasicGameState，而不是StateBasedGame。我无法在任何地方看到任何证据？
