(Name of a dog set by the player; Fido)
|
|
A dog the player can name and un-name at will.
|
|
|
|
Suppose we'd like to have a dog which the player is allowed to name himself. We'd like to deal correctly with both
|
|
|
|
>name the dog fido
|
|
|
|
and
|
|
|
|
>name the dog "fido"
|
|
|
|
so we'll also need to strip quotation marks out of the command. We can do this as follows:
|
|
|
|
{*} "Fido"
|
|
|
|
The Back Yard is a room.
|
|
|
|
A dog is an animal in Back Yard. The dog has some text called the nickname. The nickname of the dog is "nothing". Understand the nickname property as describing the dog.
|
|
|
|
Rule for printing the name of the dog when the nickname of the dog is not "nothing":
|
|
say "[nickname of the dog]"
|
|
|
|
Naming it with is an action applying to one thing and one topic. Understand "name [something] [text]" as naming it with. Check naming it with: say "You can't name that."
|
|
|
|
Instead of naming the dog with "nothing":
|
|
now the nickname of the dog is "nothing";
|
|
now the dog is improper-named;
|
|
say "You revoke your choice of dog-name."
|
|
|
|
Instead of naming the dog with something:
|
|
let N be "[the topic understood]";
|
|
replace the text "'" in N with "";
|
|
now the nickname of the dog is "[N]";
|
|
now the dog is proper-named;
|
|
say "The dog is now known as [nickname of the dog]."
|
|
|
|
Test me with "name the dog Fido / name the dog Lawrence / look / x lawrence / name Lawrence nothing / look / x lawrence".
