Don, thanks for your help.

<div class="">It seems like key events are better, because the programmer can access the pressed/released options. On the other hand mouse click events are better, because the programmer can specify exactly which objects can be clicked on. I wish both types
of events had both features.</div>
<div class=""><br class="">
</div>
<div class="">I can almost get the same functionality as “while something is true” by adding a timer event with the time set to 0. Then it is triggered every frame and I can check something with an if block. Most of the things we needed to do with “while something
is true” or “when something becomes true” have to do with collision detection anyway, and now there is an event for that. I’m just going to have to rearrange the order I teach some things, so collision detection can go earlier and things that in Alice 3 require
if blocks can go later.</div>
<div class=""><br class="">
</div>
<div class="">Apparently there is no equivalent of the “during” part of an Alice 2 event, but that was always something of a hack anyway. Objects can get into weird states when they stop in the middle of doing something.</div>

James,
<div class="">It seems that I have been nothing but a disappointment to you this week. There really is not a way that I have found to implement the functionality that you are looking for.</div>
<div class=""><br class="">

<div class="">Perhaps the community has thoughts?</div>

<div class="">All the best,</div>

In Alice 3, is there a way to handle different key events before introducing if blocks? In Alice 2, we used to use a separate event for each key, and then call a method. In Alice 3, I have to use “if event isKey(key)” in an if structure in order to call separate
procedures for separate keys. (See screenshot.) Is there another way? I wanted to delay teaching if blocks just a little longer.
