Designating target

Jolting Arc (Ex) Once every 1d4 rounds as a standard action, a patrol-class security robot can shoot an arc of electricity at up to four creatures within 40 feet ....

in my scene, i have, 3 players and an Unattended weapon (from a player).

with this hability.... Can I designate the unattended weapon as a target?

I would say no since the ability states creatures...

The same thing happens to me, but it's too tempting not to go for the unattended weapon on the ground. XD

Since the average weapon apparently has a Hardness of 5+(2xlevel) its unlikely the arc will damage a level 1 item to any significant degree.... I still like the idea though.

Edit to add, I recently looked up sunder for one character and since it would take multiple rounds to cause a negative, it would be faster to just KO the guy in the same number of rounds

Even if it does not harm it, it is easy to scare a player when his gear is in danger, my players have an ease of ...
I drop the weapon and draw another.

edit to add: All the rules that I have seen of abilities of randomly chosen creatures, they target creatures, I have also seen some that refer to a piece of gear, but it is very very rare.
With my current knowledge of the rules, the one way to damage an unattended object is with an explosion, (see grenade or fireball), hence my initial question.

Random invisible creatures coming up to steal the dropped items and immediately running away stopped rampant weapon dropping for me. There is just something about theft that is more traumatic than destruction.

I like it, however the one character in my group who drops his weapon (Intentionally) has the called fusion on both weapons.

My intention is not only to damage the weapon, that there are few possibilities, but that if an unattended weapon can be targeted, count for example to make arc.

For example
Jolting Arc: Between targets they cannot be more than 30 feet in a maximum range of 40 from the creature. Player A and B are within 10 of each other but C is within 35 of B but within 40.
Although this is not the case in my scene, if the weapon counted as a target, being 5 feet from B and 30 from C it could hit 4. xD.

is a Example.

the target's definition: Some effects have a target or targets. You use these effects on creatures or objects, as defined by the effect itself.
....
Some effects restrict which targets can be selected. If an effect targets living creatures, it affects all creatures other than constructs and undead
....
Other effects allow you to target other categories of creatures or items, such as effects that can specifically target a construct, corpse, or object.

the effects that point to objects that I have seen, it is true that I have seen few, always referred to attended objects. That is why my question was related to unattended objects can be objective even if I put creature in the description,
According RAW I would say no, but it seems strange not being able to select them.

I do wonder why they keep the "creature" targeting requirement. It seems like weird leftover cruft from earlier editions. Just say "Attacks N Targets", and then give a *descriptive, non-exclusive* definition of 'Target' somewhere else in the rules. Something like "A Target is a distinct individual recipient for an attack, like a creature, an object, a vehicle, or a specific piece of terrain. An object in someone's possession is not a valid Target unless otherwise specified."

Basically, the only effects that should be limited to effecting creatures, is things which specifically hinge upon the creature being a living thing. A death effect or a poison logically should only target a creature and not an inanimate object; something which does physical damage should not be so limited.
