The obstacle needs navigation data to work correctly. This can be done by having the obstacle as a child of a [Navigation] node, or using [method set_navigation]. [NavigationObstacle] 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. </description> <tutorials> </tutorials> <methods> <method name="get_navigation" qualifiers="const"> <return type="Node" /> <description> Returns the [Navigation] 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 [NavigationServer]. </description> </method> <method name="set_navigation"> <return type="void" /> <argument index="0" name="navigation" type="Node" /> <description> Sets the [Navigation] node used by the obstacle.
