11<h1 id="TUTORIAL_MAKE_CHILD">Ripple Effect Using Children</h1>
12<p>In this tutorial, we describe how to create child particles using the ripple effect caused by falling water in a fountain as an example. </p>
13<p>For a detailed description of how to create effects, click <a href="make_effect.html">here</a>.</p>
14<p>The basic procedure is given below.</p>

21<h2>Preparing to Create the Effect</h2>
22<h3>Confirming the Loading of the File</h3>
23<p>The effect file used in this tutorial is located in the folder given below. </p>
24<p>&quot; SampleData/Effect/Intermediate/ManualResource/Fountain_Effect/Fountain_Effect_Mid_Flow.cptl &quot;</p>
25<p>Effect files created for this tutorial are located in the following location.</p>
26<p>&quot; SampleData/Effect/Intermediate/ManualResource/Fountain_Effect/Fountain_Effect.cptl &quot;</p>
27<h3>Creating a new project</h3>
28<p>On the main menu, select File &gt; New &gt; Project to open a dialog box for creating new projects. </p>
29<p>Without changing the project name, just press OK.</p>
30<h3>Loading effects</h3>
31<p>On the main menu, select <B>File &gt; Open</B>, and load the file Fountain_Effect_Mid_Flow.cptl located in the folder Fountain_Effect.</p>
32<p>Select Fountain and press F5 to transfer data to the <B>Viewer</B>. </p>
33<p>Check the fountain effect on the <B>Viewer</B>.</p>

36<h2>Creating Child Particles</h2>
37<p>Here, we use child particles to create ripples generated when fountain particles strike the ground.</p>
38<p>Select Fountain_Drop_Particle.</p>
39<p>The following methods of creating child particles are available.</p>
40<ul>
41  <li>Press <B>Add a new child particle</B> on the <B>Project Window</B> tool bar to open a dialog for creating a new effect. </li>
42</ul>
43<p>Enter Fountain_Ripple_Particle for the child particle name and press OK.</p>
44<p>At this point, the following entries are shown for Fountain.</p>
45<ul>
46  <li>Fountain_Drop_Particle represents the fountain particle </li>
47  <li>Fountain_Ripple_Particle represents the ripple created using child particles when the fountain particle strikes the ground.</li>
48</ul>

50<h2>Setting Child Particles</h2>
51<p>Here, we set the child particle representing the ripple.</p>
52<h3>Emitter Settings</h3>
53<p>Here, we set the emitter so that the ripple particles are emitted when the fountain particles hit the ground. </p>
54<p>Double click Fountain_Ripple_Particle to open the <B>Property Window</B>.</p>
55<p> Select <B>Child particles</B> and check that <B>Timing</B> is set to <B>When parent particle expires</B></p>
56<h3>Other Settings</h3>
57<p>As for other settings, you can copy child settings by loading the finished effect file Fountain_Effect. </p>
58<p>Check the ripple effect when fountain particles strike the ground on the <B>Viewer</B>.</p>
