Stopping a walking soundloop upon death

I have the following code for a character controlled by the user so that when he is walking the "dirt_walking" sound plays in a loop and stops when he stops walking. However, when the character gets eaten by a wolf or bear while walking, the walking sound continues in the loop. I've been struggling to have it stop upon the character's death for several days, so if anyone has a suggestion, feel free to share. Thanks.

I guess the issue is that the wolf/bear removes the character from the world, so its act method of the character isn’t executed anymore. Try to stop the sound right before removing the object.

As a continuation of the post made by Super_Hippo, best may be to add a simple method to the Guy class for when it dies. Call this new method from wolf/bear classes to "kill" him:

public void die() {
    walkSound.stop();
    getWorld().removeObject(this);
}

I've already tried it making a seperate 'die' method, as well as a seperate boolean and stopping the sound before the actor gets removed, but the loop always continues. What do you mean by 'call this new method from wolf/bear classes'?

I mean add the "new method" above, die(), to your Guy class. Then you can use something like the following in the Bear and Wolf classes:
?

Guy guy = (Guy)getOneIntersectingObject(Guy.class);
if (guy != null) guy.die();
