As his post on Newbie Central demonstrates, I think you confused him with Find(); it's not appropriate for this situation (although locate() would be).

His Contains() proc would have worked alot like Find() so I recommended he look it up. locate() so is the example you posted in Newbie Central. I just wanted him to know a proc like the one he requested was already there.

But Find() isn't at all correct for searching for items of a specific type in a list, which was my point. Find() is only appropriate for situations where you'd loop through checking if A==B, not istype(A,B). locate(), however, can search according to the type of its expected return value.

Locate is also nice in that it will return a reference to the object, if you need it:

mob/proc/flashlight_on()
var/flashlight/F = locate (/obj/flashlight) in usr.contents
if(F)
F.turn_on()
else
usr << "You don't have a flashlight!"

A silly example, since the verb should be on the flashlight itself, but you get the idea.

Oops, I had almost completely forgotten that you can use locate like that for any container. That will cut down on some of my code in my current project because I have the ants look arround them every once in a while for food, other ants, ect.
