Scatter

</h1>
|
|
<p>
|
|
Scatter objects are UI elements that can be rotated, scaled or moved around which typically leads to "scattered" layouts.
|
|
The PIXI scatter defined here is a specialization of the
|
|
<a href="../scatter.html">abstract scatter pattern</a>.
|
|
</p>
|
|
<p>PIXI scatter are organized in
|
|
<code>ScatterContainer</code> parent nodes and
|
|
<code>DisplayObjectScatter</code> child nodes.
|
|
<p>Let's look at an example of a PIXI scatter. Since scatter objects are mainly used as main views it is a common use
|
|
case that the scene itself is used as the
|
|
<code>ScatterContainer</code>. The
|
|
<code>DisplayObjectScatter</code> is simply used as a wrapper that makes any interative DisplayObject zoomable, rotatable and translatable.</p>

Nested Scatter

|
|
<p>
|
|
Sometimes it can be required, that multiple scatters are nested in one another. E.g. when a map is displayed as scatter and
|
|
another scatter is displayed on the map.
