<h3 class="subsection"> C.2.3 Input Helper Changes </h3>
<a name="1"></a>
<h4 class="subsubheading"> Input Definitions </h4>
<p>The file <tt>‘csutil/inpnames.h’</tt> has been renamed to
<tt>‘inputdef.h’</tt>, and the following functions have been removed:
</p>
<ul>
<li>
<code>csTypeOfInputDef()</code>
</li><li>
<code>csParseKeyDef()</code>
</li><li>
<code>csGetKeyDesc()</code>
</li><li>
<code>csParseMouseDef()</code>
</li><li>
<code>csGetMouseDesc()</code>
</li><li>
<code>csParseJoystickDef()</code>
</li><li>
<code>csGetJoystickDesc()</code>
</li></ul>
<p>These functions allowed you to convert a string such as <kbd><kbd>Ctrl</kbd>+A</kbd>,
<samp>‘JoystickX’</samp> or <samp>‘Alt+Mouse1’</samp> into values describing input events
and vice versa.
</p>
<p>The way to do this is now, however, is to use <samp>‘csInputDefinition’</samp>, which
resides in <tt>‘csutil/inputdef.h’</tt>. The preferred way to convert a string to a
definition is to construct a <samp>‘csInputDefinition’</samp> from a
<samp>‘char const*’</samp>; and the preferred way to convert a definition back to a
string (perhaps constructed some other way) is via
<code>csInputDefinition::ToString()</code>.
</p>
<p>There are also static helper methods in <samp>‘csInputDefinition’</samp> which accept
arguments in a similar way to the old functions. These are convenience methods
which perform the work of instantiating the object for you:
</p>
<ul>
<li>
<code>csInputDefinition::ParseKey()</code>
</li><li>
<code>csInputDefinition::GetKeyString()</code>
</li><li>
<code>csInputDefinition::ParseOther()</code>
</li><li>
<code>csInputDefinition::GetOtherString()</code>
</li></ul>

<h4 class="subsubheading"> Mouse Corrections </h4>
<p>Mouse buttons and axes used to be enumerated basis 1 (first mouse button was 1,
Y axis was 2, etc). In keeping with good C/C++/Java/etc coding style, they are now
basis-0 (first mouse button is 0, Y axis is 1, etc).
</p>
<a name="3"></a>
<h4 class="subsubheading"> Joystick Corrections </h4>
<p>The implementation of <samp>‘iJoystickDriver’</samp> has been fixed to treat joystick
numbers consistently. Previously, on account of buggy implementation, some
parts of the driver considered joystick numbers 0-based, while other parts
considered them 1-based. It now uniformly treats joystick numbers as
0-based. This is consistent with button numbers for joysticks and mice, which
are also basis-0.
