2D obstacle used in navigation for collision avoidance.
</brief_description>
<description>
2D obstacle used in navigation for collision avoidance. The obstacle needs navigation data to work correctly. This can be done by having the obstacle as a child of a [Navigation2D] node, or using [method set_navigation]. [NavigationObstacle2D] is physics safe.
Obstacles [b]don't[/b] change the resulting path from the pathfinding, they only affect the navigation agent movement in a radius. Therefore, using obstacles for the static walls in your level won't work because those walls don't exist in the pathfinding. The navigation agent will be pushed in a semi-random direction away while moving inside that radius. Obstacles are intended as a last resort option for constantly moving objects that cannot be (re)baked to a navigation mesh efficiently.

<methods>
<method name="get_navigation" qualifiers="const">
<return type="Node" />
<description>
Returns the [Navigation2D] node that the obstacle is using for its navigation system.
</description>
</method>
<method name="get_rid" qualifiers="const">
<return type="RID" />
<description>
Returns the [RID] of this obstacle on the [Navigation2DServer].
</description>
</method>
<method name="set_navigation">
<return type="void" />
<argument index="0" name="navigation" type="Node" />
<description>
Sets the [Navigation2D] node used by the obstacle. Useful when you don't want to make the obstacle a child of a [Navigation2D] node.
