§6.10. Entering and Exiting, Sitting and Standing
Under ordinary circumstances, Inform does not keep track of the player's posture, nor of his exact location in a room. Lies implements a room in which the player can lie in different positions on the floor, getting different views as a result.
Our other examples are all modifications of the way Inform handles player movement to make better default guesses at what he wants to do: Anchorite adds a GET DOWN and DOWN command that work when the player is on a supporter, to accompany GET UP, GET OFF, and GET OUT (already understood). Get Axe makes the player get out of a portable container before attempting to lift it - a consideration that comes up relatively rarely, but that might pertain to inflatable rafts, beanbag chairs, and other lightweight but capacious pieces of furniture.
See Position Within Rooms for a box the player can push around the room and stand on in different locations
See The Human Body for letting the player sit, stand, or lie down systematically on furniture or on the floor
See Furniture for various objects on which the player can sit or stand
|Start of Chapter 6: Commands|
|Back to §6.9. Going, Pushing Things in Directions|
|Onward to §6.11. Waiting, Sleeping|
We could now re-write the check rules so that any time someone (the player or someone else) tries to pick up a container which he is in, he will first get out:
With GET DOWN, we can replace the whole command, which will not interfere with the normal function of the TAKE verb, or allow the player to attempt to GET any other directions:
The Solitary Place is a room. "A glittering, shimmering desert without either locusts or honey." The pillar is an enterable supporter in the Solitary Place. "The broken pillar is short enough to climb and sit on." The description of the pillar is "Once it was a monument: a long frieze of battles and lion-hunts spirals up the side, in honor of an earthly king." The player is on the pillar.
This doesn't cover the case where the player just types "DOWN", and we don't want to preempt the normal operation of the GO action here. So instead of writing a new understand instruction, we might catch this one at the action-processing level:
To set the scene, and make new actions to provide for two of these ways:
The Laundry is a room. "An old Limehouse haunt, the Chinese laundry used by the down-trodden wives of the Tong of the Black Scorpion." The vast marble sink is here. "There is nothing obviously oriental about the vast marble sink, which is large enough to lie down inside. A wooden-rack floor, equipped for easy drainage, turns out also to be equipped for snagging the shoes of passers-by." The sink is an enterable container, fixed in place.
Instead of lying near the sink, say "Lying down close to the cool butcher's marble slabs of the sink, your attention is caught by the sight of coolie shoes through a floor-level grille for ventilation. The game is afoot!"
So far, so good. Now for the grammar, where we create two new tokens: one for each of two groups of alternative prepositions.
