<brief_description>

<methods>
<method name="is_on_screen" qualifiers="const">
<return type="bool">
</return>
<description>
If [code]true[/code], the bounding box is on the screen.
Note: It takes one frame for the node's visibility to be assessed once added to the scene tree, so this method will return [code]false[/code] right after it is instantiated, even if it will be on screen in the draw pass.
