RE: [Xenocide-programming] datainterfaces update

[Cpt. B. <cpt...@pr...>]

Here's the breakdown that I'm using in config.items.xml.  It's fairly
comprehensive for everything that a carriable item needs to do:

weapon - carriable, has actions, does damage (eg: pistol, rifle,
grenade)

		autoshot(3-round burst)		(range, accuracy,
timeunits)
		snapshot(single round)		(range, accuracy,
timeunits)
		aimedshot(single round)		(range, accuracy,
timeunits)
		throw (single item)		(damage, accuracy,
timeunits)
		touch (hand-to-hand)		(damage, accuracy,
timeunits)
		prime (time delay)		(range, timeunits)
									
equipment - carriable, has actions	(eg: mind probe, motion scanner,
ammo)
	
		throw					(damage,
accuracy, timeunits)
		scan					(range,
accuracy, timeunits)
		heal					(wound, range,
accuracy, timeunits)
		psi					(power, cost,
range, accuracy, tiemunits)
		reload (ammo)			(unit, damage,
timeunits)

If you want particular set of objects to expose common behavior, then
you
should create an interface with methods for that behavior and inherit
all
objects from it.

In this case, I think good idea would be to have interface IHandHeld,
which
will define methods particularly for objects in the person hand. The
interface would have methods like: canThrow(), canShoot(), throw(),
shoot(),
etc. First two methods will let caller know whether the action is
available
(and actually does something). Second two methods will perform the
action
itself, if it is applicable to the object (shoot() may not be applicable
to
knives, so it will have no operation implementation).

Does it make sense?

mamutas

And how do I determine which classes did the item in the player's hand
inherit? Try to call the appropriate function and catch the exception?
I'm
sorry, but it's absolutely unclear for me.
