<p><font size="4">Hi,</font></p>
<p>Catching up with the Cuis changes for the Cuis book.<br>
</p>
<p>Arrow keys needed in the SpaceWar game of the book to control one
of the ship.<br>
</p>
<p><font size="4">upArrow and friends are gone from the Character
class.</font></p>
<p><font size="4">In this class, I read now smalltalkUpArrow,
smalltalkRightArrow, etc.</font></p>
<p><font size="4">When used in the game, I observe smalltalkUpArrow
and smalltalkRightArrow are reversed:</font></p>
<p><font size="4">- when I press the up arrow of the keyboard, the
ship turn right</font></p>
<p>- when I press the right arrow the ship gets an engine thrust.</p>
<p>I don't know if their numeric values can be safely reversed or if
there is any other consideration, for example with VM events.</p>
<p>Thanks</p>
<p>Hilaire<br>
