+## Areas players can interact with (i.e. something that is part of the room's background: the sky,
+## an entrance to a cave, a forest in the distance).
+##
+## When selecting a Hotspot in the scene tree (Scene dock), Popochiu will enable three buttons in
+## the Canvas Editor Menu: Baseline, Walk to, and Interaction. This can be used to select the child
+## nodes that allow to modify the position of the [member PopochiuClickable.baseline],
+## the position of the [member PopochiuClickable.walk_to_point], and the position and the polygon
+## points of the [b]$InteractionPolygon[/b] child.
