I am making a game rigt now with a character that is able to loose hp. I want to show the hp with a healthbar by replacing the image of my healthbar everytime the actor gets damage, but i dont know how to do it.

Create the current image in a seperate method:

private void updateHealthBarImage()
{
    GreenfootImage img = ...
    ...
    setImage(img);
}

Then call it from the method where damage is taken:

hp--;
updateHealthBarImage();

You should also be able to use the update method to initialize the image of the health bar.

You will have to show what you tried so we can find out where you went wrong.

Actor:

public void leben(int amount)

       hp = amount;
     
       if(unverwundbarkeit == false)

       if(isTouching(kleinespinne.class))

           getWorld().removeObjects(getObjectsInRange(80,kleinespinne.class));
           
            unverwundbarkeit = true;
           hp-=1;
        }

            unverwundbarkeit = false;
            }
          
        }
     }

healthbar:

public void act() 


    {
        if(! getWorld().getObjects(Jim.class).isEmpty())
        {  
         Jim jim = (Jim)getWorld().getObjects(Jim.class).get(0);
       
        int jimX = jim.getX();
         int jimY = jim.getY();
         setLocation(jimX,jimY -50);
    } 
}
   public void jimhpupdate(){
       MyWorld MyMyWorld = (MyWorld) getWorld();
       Jim jim =  MyMyWorld.getjim();
       jim.leben(5);
       
       
        
    if(hp==5)
    {
        setImage("jimhp1.png");
    }

    }
     if(hp==1)
    {
        setImage("jimhp1.png");
    }
    

 }

world:

 public Jim getjim()
 { return jimm;
    }

Is it on purpose that you have "timer3" on the left, but "timer" on the right?

this.timer3 = this.timer +1;
