<h1>phy_active</h1>
<p>This variable controls whether or not the instance is currently "active". Setting it to <tt>false</tt> will prevent the instance from participating in the physics world, and setting it to <tt>true</tt> will have it participating again. Please
note that this is not the same as <a href="../../Asset_Management/Instances/Deactivating_Instances/Deactivating_Instances.htm">deactivating the instance</a>, as the instance is still visible on the screen and can still be changed through code, rather
this function just prevents it from participating in the physics simulation</p>
<p> </p>
<h4>Syntax:</h4>
<p class="code">phy_active;</p>
<p> </p>
<h4>Returns:</h4>
<p class="code">Boolean (or <tt>undefined</tt> if the instance is not physics enabled)</p>
<p> </p>
<h4>Example:</h4>
<p class="code">if keyboard_check_pressed(ord"P")<br/> {
<br/> global.Pause = !global.Pause<br/> with (obj_Parent)<br/> {
<br/> phy_active = !global.Pause;<br/> }
<br/> }
</p>
<p>The above code will detect a keypress of the letter "P" and then toggle the global variable "Pause" from <tt>true</tt> to <tt>false</tt> and back again. This variable is then used to set whether physics is active or not in the children
instances of the object indexed in the variable "obj_Parent".</p>
