Hello there, i have a fish named "Yellowfish" and he needs to dodge all balls from "Greenfish" who spit a ball named "Giftkugel" How can i shoot to the location, where my Yellowfish is AT THE MOMENT? Do i need to write that in the ball "Giftkugel" or the one who spits it, "Greenfish"?

You can write that in either class. I think, however, I would do it in the Giftkugel class to avoid excess code in the Greenfish class by making use of the addedToWorld method.

Thank you so much. but another question, what do I need to write? Im just having this in my public void act at Giftkugel: this.move(10); if(this.isAtEdge()) this.getWorld().removeObject(this); ---

... to set rotation.

Well, tried 5min to get it but the balls are just imitating me when i go somewhere. They just need to spit at the direction where my yellowfish was at this moment, not imitating me.

    Actor yellowfish = (Actor)getWorld().getObjects(Yellowfish.class).get(0);
    setRotation(yellowfish.getRotation());
    this.move(7);
    if(this.isAtEdge())
    this.getWorld().removeObject(this);

That looks like you have it in your act method -- not the addedToWorld method. Also, you do not want to take on the rotation of the yellow fish -- you want to turn towards it.

yesss my bad. its working. thank you! for all, who wants to get the code:

    public void addedToWorld(World w){
    Actor _NAME_ = (Actor)getWorld().getObjects(_YOURACTOR_.class).get(0);
    turnTowards(_YOURACTOR_.getX(), _YOURACTOR_.getY());
