*** Relations involving values

(Character who learns new actions by watching the player; For Demonstration Purposes)
|
|
A character who learns new actions by watching the player performing them.
|
|
|
|
Suppose we want to have a character who can dynamically learn new actions by observing the player performing them. We could do this by adding the actions to a list of things the character can do, but using a relation to express the same idea allows for tidier, easier-to-read code.
|
|
|
|
Thanks to Jesse McGrew for the initial design of this example.

{*}"For Demonstration Purposes"
|
|
|
|
Section 1 - Procedure
|
|
|
|
Capability relates various people to various stored actions. The verb to be capable of means the capability relation.
|
|
|
|
Persuasion rule:
|
|
let CA be the current action with no specific actor;
|
|
if the person asked is capable of CA:
|
|
persuasion succeeds;
|
|
otherwise:
|
|
say "[The person asked] look[s] confused. Maybe a demonstration would help.";
|
|
persuasion fails.
|
|
|
|
The action requester is an object that varies. The action requester variable translates into I6 as "act_requester".
|
|
|
|
To decide which action is the current action with no specific actor:
|
|
let old actor be the person asked;
|
|
let old requester be the action requester;
|
|
now the person asked is the player;
|
|
now the action requester is nothing;
|
|
let CA be the current action;
|
|
now the person asked is the old actor;
|
|
now the action requester is the old requester;
|
|
decide on CA.
|
|
|
|
The learning by observation rule is listed after the report stage rule in the specific action-processing rules.
|
|
|
|
Definition: a person is other if he is not the player.
|
|
|
|
This is the learning by observation rule:
|
|
repeat with the viewer running through other people who can see the player:
|
|
if the player is the actor and viewer is not capable of the current action:
|
|
say "[The viewer] watches your behavior with interest. Seems like [they] [are] learning.";
|
|
now the viewer is capable of the current action.
|
|
|
|
Section 2 - Scenario
|
|
|
|
The Daily Planet is a room. Clark is here. He is a man.
|
|
|
|
When play begins:
|
|
now Clark is capable of taking inventory.
|
|
|
|
Test me with "Clark, inventory / Clark, x me / x me / Clark, x me". |
