should be defined accordingly (e.g. ``const ELEMENT_WIND = 8`` and so
on).
Export hints are also provided for the physics and render layers defined in the project settings::
export(int, LAYERS_2D_PHYSICS) var layers_2d_physics
export(int, LAYERS_2D_RENDER) var layers_2d_render
export(int, LAYERS_3D_PHYSICS) var layers_3d_physics
export(int, LAYERS_3D_RENDER) var layers_3d_render
Using bit flags requires some understanding of bitwise operations. If in
doubt, boolean variables should be exported instead.
