|

; notes:
|
||||
;
|
||||
; * keeping with a view/logic separation, although this is quite different to
|
||||
; the hexagon game. the main advantages:
|
||||
; - just a divide and conquer strategy for staying sane
|
||||
; - able to debug the logic without the view, or vice versa
|
||||
; - the logic can be ticked at a lower frequency - or even different
|
||||
; parts at different rates, whereas the view needs ticking every frame
|
||||
;
|
||||
; * need to try to keep all the intensive 'every thing vs every thing' checking
|
||||
; in the logic side, where it can be done over many frames (i'm thinking the
|
||||
; lags involved with things like nutrients getting absorbed may not matter
|
||||
; too much in this game)
|
||||
;
|
||||
; * using a message passing system to formalise the passing of information on
|
||||
; the logic side. this makes it possible to have objects sending messages
|
||||
; at any point, and have them automatically collected up and dispatched to
|
||||
; the view
|
||||
;
|
||||
; * these messages are also converted to xmpp messages and sent out over the
|
||||
; network
|
||||
;
|
||||
; * line segments are computed in the logic side, and can be represented any
|
||||
; way by the view - maybe the players plant will be geometry and everyone
|
||||
; elses will be ribbons (stoopid LOD)
|
||||
;
|
||||
; * in the same way, the line segments can be created in any way by the logic
|
||||
; side - eg. lsystem, or different methods per plant (or per twig even)
