I am attempting to make a pong clone but java hates me. I have these errors: Game.render() failure - check the game code, so i checked my code and i cant find anything wrong with it. now its just says in game.render() but there is no game.render(), however these are the two render methods with code in them. i have thwo others but they are empty:

public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException{
Image mainMenuScreen = new Image("res/MainMenu.png");
Image playButton = new Image("res/playButton.png");
Image exitButton = new Image("res/ExitButton.png");

g.drawImage(mainMenuScreen, 0,0);
g.drawImage(playButton, 500, 220);
g.drawImage(exitButton, 500, 300);
}

now i have this code in another class:

Image play = new Image("res/Play.png");
Image Paddle1 = new Image("res/Paddle.png");
Image Paddle2 = new Image("res/Paddle.png");

g.drawImage(play,0,0);
g.drawImage(Paddle1,0,200);
g.drawImage(Paddle2,620,200);


this is my Game.java class:

package MyGame;
import org.newdawn.slick.*;
import org.newdawn.slick.state.*;
public class Game extends StateBasedGame{
public static final String gamename = "Pong v.1";
public static final int mainmenu = 0;
public static final int play = 1;
public static final int menu = 2;
public static final int verdict = 3;

public Game(String gamename){
super(gamename);
this.addState(new MainMenu(mainmenu));
this.addState(new Play(play));
this.addState(new Menu(menu));
this.addState(new Verdict(verdict));
}

public void initStatesList(GameContainer gc) throws SlickException{
this.getState(mainmenu).init(gc, this);
this.getState(play).init(gc, this);
this.getState(menu).init(gc, this);
this.getState(verdict).init(gc, this);
this.enterState(mainmenu);
}

public static void main(String[] args) {
AppGameContainer appgc;

try{
appgc = new AppGameContainer(new Game(gamename));
appgc.setDisplayMode(680, 400, false); //Width length fullscreen
appgc.start();
}catch(SlickException e){
e.printStackTrace();
}

}
}

The screen shows up but in about 5 sec it closes.

Its says the time and date, but other than that it is the complete error message. And yes it works, i was trying to make it able to change the state when i click the button but it closes after 5 sec and wanted to get that fixed first.

So when i press f11 the program runs and then 3 sec later is stops. i am using eclipse btw, but in the consle window it shows this:

and in the debug window it shows this:

However i removed the big image and it worked. Im not sure how to set it as the background so i set it to 0,0. the image takes up the whole space. How would i set it as the background?

also im not sure how to do the grey bar sorry.

Be careful what you put inside a draw/render loop; as stated above, you shouldn't be loading images in there.

Furthermode, it appears it can't find MainMenu.png, and throws an Exception, which leads to the top-level SlickException; that's your issue.
