[SOLVED] Animation Listener

Troubleshooting General Help
1

I’ve been developing a zombie FPS, so I’m imported a model with the all animation that I needed. So by default, the zombie walk and when the player hits the zombie, the animation change to “ReactionHit”. My problem is that I want to change the animation back to “walking” when the “ReactionHit” ends. I followed the JME3 tutorial and add the listener to the control and implement the two methods (onAnimCycleDone and onAnimChange), but when I shoot the zombie the game crashes.

ERROR: IllegalArgumentException: The given listener is already registered at this AnimControl.

CODE:

    //Here I set the default walking animation of the zombie
    private void zombieAnimation(String animation){
        control = zombie.getControl(AnimControl.class);
        channel = control.createChannel();
        channel.setAnim(animation);
        channel.setLoopMode(LoopMode.Loop);
        channel.setSpeed(1f); 
    } 
    
    //Here is where I change the zombie animation to "ReactionHit"
    private void hitAnimation() {
        channel.reset(true);     
        control = zombie.getControl(AnimControl.class);
        control.addListener(this);
        channel.setAnim("ReactionHit");
        channel.setLoopMode(LoopMode.DontLoop);
        channel.setSpeed(1f);
    }

    @Override
    public void onAnimCycleDone(AnimControl control, AnimChannel channel, String animName) {
        if (animName.equals("ReactionHit")) {
            //Here I change the animation to "Running"
            zombieAnimation("Running");
        }
    }

    public void onAnimChange(AnimControl control, AnimChannel channel, String animName) {
        //Unused
    }

this should really say it all.
You have to either unregister the listener after Running again or only ever set it up once, regardless of ReactionHit

You always (on each hitAnimation call) add the listener to the control, one time is enough. Like the error says…

It’s work. Thanks for your time!
