<a name="ClutterPath.description"></a><h2>Description</h2>
<p>A <a class="link" href="ClutterPath.html" title="ClutterPath"><span class="type">ClutterPath</span></a> contains a description of a path consisting of
straight lines and bezier curves. This can be used in a
<a class="link" href="ClutterBehaviourPath.html" title="ClutterBehaviourPath"><span class="type">ClutterBehaviourPath</span></a> to animate an actor moving along the path.</p>
<p>The path consists of a series of nodes. Each node is one of the
following four types:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><a class="link" href="ClutterPath.html#CLUTTER-PATH-MOVE-TO:CAPS"><code class="literal">CLUTTER_PATH_MOVE_TO</code></a>, changes the position of the path to the
given pair of coordinates. This is usually used as the first node
of a path to mark the start position. If it is used in the middle
of a path then the path will be disjoint and the actor will appear
to jump to the new position when animated.</p></li>
<li class="listitem"><p><a class="link" href="ClutterPath.html#CLUTTER-PATH-LINE-TO:CAPS"><code class="literal">CLUTTER_PATH_LINE_TO</code></a>, creates a straight line from the previous
point to the given point.</p></li>
<li class="listitem"><p><a class="link" href="ClutterPath.html#CLUTTER-PATH-CURVE-TO:CAPS"><code class="literal">CLUTTER_PATH_CURVE_TO</code></a>, creates a bezier curve. The end of the
last node is used as the first control point and the three
subsequent coordinates given in the node as used as the other three.
-<a class="link" href="ClutterPath.html#CLUTTER-PATH-CLOSE:CAPS"><code class="literal">CLUTTER_PATH_CLOSE</code></a>, creates a straight line from the last node to
the last <a class="link" href="ClutterPath.html#CLUTTER-PATH-MOVE-TO:CAPS"><code class="literal">CLUTTER_PATH_MOVE_TO</code></a> node. This can be used to close a
path so that it will appear as a loop when animated.</p></li>
</ul></div>
<p>The first three types have the corresponding relative versions
<a class="link" href="ClutterPath.html#CLUTTER-PATH-REL-MOVE-TO:CAPS"><code class="literal">CLUTTER_PATH_REL_MOVE_TO</code></a>, <a class="link" href="ClutterPath.html#CLUTTER-PATH-REL-LINE-TO:CAPS"><code class="literal">CLUTTER_PATH_REL_LINE_TO</code></a> and
<a class="link" href="ClutterPath.html#CLUTTER-PATH-REL-CURVE-TO:CAPS"><code class="literal">CLUTTER_PATH_REL_CURVE_TO</code></a>. These are exactly the same except the
coordinates are given relative to the previous node instead of as
direct screen positions.</p>
<p>You can build a path using the node adding functions such as
<a class="link" href="ClutterPath.html#clutter-path-add-line-to" title="clutter_path_add_line_to ()"><code class="function">clutter_path_add_line_to()</code></a>. Alternatively the path can be described
in a string using a subset of the SVG path syntax. See
<a class="link" href="ClutterPath.html#clutter-path-add-string" title="clutter_path_add_string ()"><code class="function">clutter_path_add_string()</code></a> for details.</p>

. The

by a letter and is followed by zero, one or three pairs of
coordinates. The coordinates can be separated by spaces or a
comma. The types are:</p>
