两种不同胶卷的Inform7相机

Question

嘿，伙计们，我试着实现一个照相机：

A photograph is a kind of thing. 36 photographs are in the film roll.

Appearance relates one thing to various photographs. The verb to be shown by means the appearance relation.

The description of a photograph is usually "It shows [a random thing which is shown by the item described]."

Understand "of [something related by reversed appearance]" as a photograph.

This allows the player to refer to any photograph by its subject: useful if we have a large number of them.

Now we create an action to let the player use the camera and generate these photograph objects:

The player carries a cheap instant camera.

Understand "photograph [something] with [camera]" as photographing. Understand "photograph [something] with [something preferably held]" as photographing. Photographing is an action applying to one visible thing and one carried thing, requiring light.

The photographing action has an object called the selected film.

Setting action variables for photographing:
    let N be a random photograph in the film roll;
    now the selected film is N.

Check photographing:
    if the second noun is not the camera, say "You need a camera for that purpose." instead.

Check photographing:
    if the noun is the camera, say "Sadly impossible." instead.

Check photographing:
    if the selected film is nothing, say "You're out of film." instead.

Carry out photographing:
    now the noun is shown by the selected film;
    move the selected film to the player.

Report photographing:
    say "Your camera instantly spits out [a selected film]."

类似于例322: http://inform7.com/book/RB_9_12.html

在这个例子中，只有一个带有一个胶卷的照相机。

但我想要两个不同的相机，这两个相机应该有一个单独的胶卷。

，这样我就可以用camera#1保存到filmroll#1，也可以用camera#2拍摄照片，这些照片都保存在“filmroll#2”中。

有人能帮我吗？

我想你可以用化名来做这个。我已经有一段时间没有在“通知7”中进行编码了，但我相信语法类似于：

The player carries a first camera.
The printed name of first camera is "cheap instant camera".
There is a second camera in the lab.
The printed name of second camera is "cheap instant camera".

你会有两个相机，显示为相同的东西，但是不同的。你也可以用胶卷做同样的事情。你可能仍然有问题，知道哪个相机是谁，但希望这能让你在正确的轨道上。
