   <p>A fundamental feature of most programming languages is the ability to ask a simple question that gives a boolean <span class="inline">true</span> or <span class="inline">false</span> answer, and in GML this is achieved using the <span class="inline">if</span> keyword. A simple <span class="inline">if</span> condition takes an <a class="glossterm" data-glossterm="expression" href="#">expression</a> and will perform one or more <a class="glossterm" data-glossterm="statement" href="#">statement</a><span class="glossextra">s</span> if the expression resolves as <span class="inline">true</span>, with the following basic form:</p>

   <p>It is worth noting too that you can nest conditional operations but that if you do then each operation will need to be enclosed in brackets, for example:</p>
   <p class="code">var c = a ? &quot;foo&quot; : (b ? &quot;bar&quot; : &quot;whee&quot;); // Correct<br />
     var c = a ? &quot;foo&quot; : b ? &quot;bar&quot; : &quot;whee&quot;;   // Will cause an error</p>
