hideentity/showentity usage

if im hiding and showing alot of entities should i add a flag for wether they are hidden or not so as to stop running hideentity and showentity on every entity be it hidden or not?
eg

type EntityMesh

field mesh, HiddenStatus

end type

for m.EntityMesh = each EntityMesh

if m\HiddenStatus = 1

if EntityInView(m\mesh,camera)
ShowEntity m\mesh
m\HiddenStatus = 0
endif

elseif m\HiddenStatus = 0

if not EntityInView(m\mesh,camera)
HideEntity m\mesh
m\HiddenStatus = 1
endif

endif

next
