<div>One way to do this is to have a boolean variable to control access in the event listener code. In your example, you can have a variable called “moveBoxAllowed” initially set to true. When the later point in the program is reached, set it to false. In the
event handler code, put the box movement code inside an if block that checks the moveBoxAllowed variable.</div>

<div> I have two questions. </div>
<div>1) What does the Handle Active command do in Alice 3.1?</div>
<div>2) How can you set up a program so that an object is only affected by an event listener for part of the program? For example, a student wants to have the program user move a box but only at a certain point of the program. I can't figure out how to limit
when an event listener is active. </div>
