<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

found interesting about wonderland. It’s a bit too cleaver.

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

10.0pt;font-family:Arial;color:navy'>[:event | self move: #left] since the code
is being stored on a helicopter but instead I needed to put in [:event | helicopter
move: #left]. Now it seems that Wonderland is doing what it is you want
but at the expense of making you believe this is some sort of magic. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The answer to your question is rather
simple, but it will be confusing with what you have already seen. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The answer is: Object message. Every
message is sent to an object, and objects can be either Classes or instances. But
even this is a bit confusing since Classes are instances of a Class, but forget
I mentioned that.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Now a Class can have instances. Like
this: aGlass := Glass new.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>This sets the temp variable aGlass to an
instance of the Class Glass. It’s relatively easy to find a class
in Smalltalk since it does it for you automatically. If you had created
the class Glass then select Glass and inspect_it will bring up the class
definition. This is not true for instances. You are required to
manage your own instances of a class. Normally we do this by storing instances
in instance variables. This helps to form a relationship between objects.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Thanks Ron,<br>
There's some good info. in there. Unfortunately, scene doesn't have
respondWith: to: method, but I might be able to find a workaround. <br>
<br>
One method I was trying to use in the past was to create a script from tiles,
and have that script always ticking and just send the helicopter the command to
move in response to the world's last keystroke. I couldn't get the script to
find the helicopter at all, and have been having trouble with going from one
workspace to another attempting to refer to the same thing, and also with the
differences between tile scripts and workspace scripts, for some reason they
don't act the same and I'm not sure why. Even when I tried creating a class
MyWonderland with instance variables | wonder copter |, I couldn't figure out
how to get a method to understand what 'copter' was and pass messages to it
other than the one that created it. Also related, when I define jump as <br>
jumpup := wonder helicopter move:#up.<br>
<br>
I still don't know exactly how to make this method do this again. I've tried
World jumpup. jumpup. wonder helicopter jumpup. but only jumpup loop. seems to
work, and again only from the particular workspace I defined it in. I know all
of this is related somehow. Anyone got a hint?<br>

sticking with the problem. That in my opinion is the best way to learn. I<br>
didnt answer your question because I do not feel that I am an expert in<br>
Wonderland. If the question was something like how can I map a key to so<br>
some action that is pretty easy, IF that action is an isolated easily called<br>
method. Something like: Utilities garbageCollectAndReport. This is<br>
a class method and there is no instance that needs to be sent to. <u1:p/></span></font><o:p></o:p></p>

The<br>
issue here is that there is a complicated event loop that needs to be tapped<br>

experience. <br>
The fact that you are using wonderland means that there is probably already a<br>
hook to do what you want so a complicated explanation of what I know will<br>
probably only confuse the matter and make things more difficult for you. <u1:p/></span></font><o:p></o:p></p>

and he sent you to exactly the place you needed to go. I just<br>
loaded a 3.8 image and did the helicopter tutorial. I have to say it was<br>
great fun! Wonderland is a very nice piece of code and I can see that it<br>
would be fun to play with. The tutorial is fun but the concepts are not<br>
easy and how the authors did what they did is very clever but also difficult
especially<br>
when you venture off the beaten path. You picked a hard place to<br>
start! That by itself can be very frustrating. <u1:p/></span></font><o:p></o:p></p>

color:navy'>Here is your answer but the answer is not<br>
perfect. What I noticed is that the keys only have focus when the actor<br>
is under the mouse. There may be a way to make this work in the context<br>
of a world but I couldnt get it to work that way. The world does<br>
not appear to have a reactions collection, but there does seem to be a little
hook<br>
in Scene that might have been intended to work that way. Again this is an<br>
advanced concept. I also tried adding a reaction to the ground to make it<br>
easier for this to work. The ground accepted the reaction but did not act<br>
on it. I added a reaction of [:event | self halt] but that did nothing so<br>
maybe background items like ground and sky dont quite work or dont<br>
respond to certain reactions the way other actors do. It makes sense that<br>
Wonderland might be written this way. If you added a right key press to<br>
multiple objects how is it supposed to know which item the key press should<br>
control. There could be a number of ways to fix this like adding an actor<br>
that is a control stick or something, then placing the mouse over the control<br>
stick would work the helicopter. (just a suggestion of where you might go<br>
from here)<u1:p/></span></font><o:p></o:p></p>

disappointed with this list at the moment. My last post,<br>
"beginners questions" talked about how beginners often don't get<br>
their questions answered and pointed out that often when the experts see that<br>
an answer, ANY answer, was given they then assume the question was answered, so<br>
they don't offer anything more. Now I do appreciate Matthias's honest attempt<br>
to answer the question, so I don't want this to be misconstrued as an attack on<br>
him. But he obviously misread it. And, well, once people saw that the question<br>
of how to make a wonderland actor move in response to mouse clicks had been<br>
answered, I didn't get any more help. The question I asked was how to move a<br>
wonderland actor with the arrow keys, and I need to do that without the actor<br>
having the focus. Unfortunately, since it's been taking so many hours for the<br>
messages I've tried to send to get posted on here, (I think I had screwed up<br>
joining the list somehow, and redid it so hopefully that problem is solved), it<br>
took me a full day to get my question asked and now another full day to explain<br>
that the answer I got was to a different question. By the by, I've been<br>
spending about 10 hours a day for 5 days now trying to solve this problem. It's<br>
getting quite frustrating for me and making me want to give up on squeak. <img
