Hello, I have been having problems with adding background music to my game. For some reason I can not import the music into the game from the sound folder an error comes up: Caused by: java.io.FileNotFoundException: Could not find file: Disconnect_Music.mp3 at greenfoot.util.GreenfootUtil.getURL(GreenfootUtil.java:554) at greenfoot.sound.SoundFactory.createSound(SoundFactory.java:99) ... 12 more This is my code: 
public void music(){
     Greenfoot.playSound("energy.wav");
     if (musicTimer == 100000){
     Greenfoot.playSound("Disconnect_Music.mp3");
    }
    if (musicTimer == 20000){
    Greenfoot.playSound("Fade_Music.mp3");
    
    
    }
    if( musicTimer == 30000){
    Greenfoot.playSound("Titans_Music.mp3");
    
    
    
    
    
    
}*/
In addition, I trying to work with gifs to animate my character, however I am having trouble finding the greenfoot commands, is there somewhere I can look to give me a broader understanding of gif manipulation and integration

Copy the music files into the 'sounds' folder within the project folder manually. Check out my GifImage vs Animation scenario. You can download it and open it in greenfoot to see how the two classes work for animation and then you can decide which might suit your needs better.

Hello, I have looked through your tutorial on gif Images. However, when using the setImage() method im my act() it creates the error of: java.lang.NullPointerException at Dragon.act(Dragon.java:30) at greenfoot.core.Simulation.actActor(Simulation.java:604) at greenfoot.core.Simulation.runOneLoop(Simulation.java:562) at greenfoot.core.Simulation.runContent(Simulation.java:221) at greenfoot.core.Simulation.run(Simulation.java:211) Edit: well only the at Dragon.act(Dragon.java:30) comes up red 
 private GifImage Dragon_Animation;

public void act() 
    {
     
      
       animation();
       
       setImage(Dragon_Animation.getCurrentImage());
    }    

 public void animation(){
      GifImage Dragon_Animation = new GifImage("images/Dragon.gif");
      setImage(Dragon_Animation.getCurrentImage());  
    }
