* get a shock if s/he touches it, but is
* otherwise unaffected if s/he tries to use
* a verb that doesn't involve physical contact
* with the device.
*
* Requires TADS compiler 2.1 or higher.

* This is our electrically dangerous object.
*
* The shock feature relies on the new "dobjGen"
* method that was added to TADS in version
* 2.0.13. Consult your TADSVER file for more
* details on this useful feature.
*
* All this implementation does is catch every
* single verb for which the transformer is the
* direct object. If the verb in question is of
* of the "contactVerb" type then the function
* named "electricShock" is called. If the verb
* isn't of this type then it's left alone.
*
* This method uses the "isclass" function to
* check if the verb being passed (v) is of
* the "contactVerb" class or not.

* This is a *nice* example, though, so
* this and nastier ideas are left up
* to you.
*
* "electricShock" is implemented as
* a function rather than being part of
* of the transformer item so it's
* easily re-used should you have
* several electrically dangerous
* objects. Of course, you could always
* create a class of electrically nasty
* items and incorporate the "electric

/*
*
* This is a new class of verb.
*
* The idea behind it is to have
* a way of identifying all verbs
* that involve the player touching
* the direct object. You would
* modify your "adv.t" file so that
* all "touchy" verbs - such as
* "take", "push", "open", etc. -
* are of the "contactVerb" class.
*
* For instance, you would directly
* change the "touchVerb" verb from a
* regular deepverb to a contactVerb,
* by modifying your "adv.t" file like
* this:
*
* touchVerb: contactVerb
*
* Note that TADS now has a "replace"
* feature that lets you make this
* sort of change to your adv.t file
* by adding the change to your own
* game code. Check the TADSVER file
* for more info. Note that the "modify"
* isn't much use here, as "modify"
* doesn't let you change superclasses.
*
* This class will allow the game to
* distinguish between player actions
* that result in a nasty shock, and
* those actions that don't, such as
* simply looking at or asking about
* the item.
*
* The verb inherits everything from
* the "deepverb" definition. In fact,
* it doesn't do anything new itself.
* It's just a kind of flag so that
* electrically nasty items can tell
* whether a verb involves physical
* contact or not.
