So basically I just wanted to have the rocket in my game rotated without having to edit the picture since that gives me white borders again, however, I always get the error "non-static method rotate(int) cannot be referenced from a static context. I looked it up online and tried to create an instance from the GreenfootImage class, but it's set to private. So what can I do?
The method in question is prep().
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* @T. B., Klasse 10
* Das ist die Raketen-Klasse, in dieser wird bestimmt, was die Raketen-Objekte machen sollen...
*/
public class Rakete extends Actor
{
private int leben;
public Rakete(){
leben=3;
}
public void prep()
{
GreenfootImage.rotate(90);
}
public void act(){
prep();
if(Greenfoot.isKeyDown("right")){
move(3);
}
if(Greenfoot.isKeyDown("left")){
move(-3);
}
if(Greenfoot.isKeyDown("up")){
setLocation( getX() , getY()-3);
}
if(Greenfoot.isKeyDown("down")){
setLocation( getX() , getY()+3);
}
World w=getWorld();
w.showText("Anzahl Leben: "+leben, w.getWidth()/2, w.getHeight()-20);
}
public void lebenEingesammelt(){
leben++;
}
public void gestorben(){
leben--;
}
}
