I don't think the pre-game order writing is any different to the in-game
ordering. It may turn out that players tend to start the game with a
portfolio of complex orders that they anticipate being all they need for
the game, and spend the game just assigning them as appropriate.

This can be ignored for now, of course.


As for orders, we could have something like this:

Trigger datatype, essentially a function of type WorldState -> Bool

onTrigger :: Trigger -> State -> State -> State

With the orders

  --------------------      See enemy unit       ------------------
  |Go to waypoint foo|==========================(Destroy enemy unit)   
  --------------------                           ------------------   
            |
            | Got to waypoint foo
            |
            *

we could have

state1 = onTrigger see_enemy_unit (destroy_enemy_unit state1)
       $ onTrigger (got_to_waypoint "foo") nostate
       $ go_to_waypoint "foo"

I don't think this gets us any closer to order updating.

I guess the engine probably wants to work by working out how long it is
until the next trigger happens rather than stepping time and testing
them; this will have to be updated every time the user does anything
that might change it, of course.
