The game type has a list of shapes in play, and the shape methods need to know about what game they are updating when they do stuff.


I don't fully understand why this is wrong and how it fits with the advice given or the initial question asked.
Isn''t this simply
type Tgame
   field shapes_inplay:tlist   ' pointing to tshape.list
end type
type tshape
  global list:tlist=createlist()
  field parent:tgame
end type

I do this and don't have a problem (unless I am missing something). It matches the statement I quoted but not the original posted question so I must have confused something.
