Hello, I had some trouble with importing a gif for an object, I saw some videos about this where they impoted a new class, named GifImage. On my version of greenfoot I cant import this. Is there a way to fix this error? The image of the object is now the image of the gif but its not moving.

I do not see anywhere where you invoke a change in its image. That is, the following is not found anywhere in your code: 
setImage(myGif.getCurrentImage());
This should be in the act method somewhere.

Replace lines 11 thru 14 with the following: 
GifImage myGif;

public Draak() {
    myGif = new GifImage("draak 11.gif");
}
You need to have the GifImage class added to your scenario. If you have to, create any type class and replace all its code with the contents of the following file: greenfoot > lib > greenfoot > common > GifImage.java
