<p>Don,</p>
<p>Could you send a code sample, preferably in Alice 2, showing an example of what you described here?</p>

One solution would be to create a Boolean variable for the Scene / World, maybe called isActive, with an initial value of true.<br>
<br>
In the event, create an if... statement<br>
if (isActive)<br>
<br>
And then the work of the event would be inside the if statement code block...<br>
<br>
You would set the isActive variable to false at the point in the program where the user should NOT be able to move the wolf.<br>
<br>
Let me know if you have any questions...<br>
<br>
All the best,<br>
