jjacek says The problem being that inventory items have two internal "types", yet neither reflects the full spectrum of actual user-visible types
Dec 08, 2008 - 03:22AM

jjacek says The solution is to augment those types with a new class attribute, then phase out use of the other two types until they are replaced
Dec 08, 2008 - 03:23AM

jjacek says By using a bitfield, with each possible type being represented as a power of two (1, 2, 4, ...
Dec 08, 2008 - 03:24AM

jjacek ... the new type field also becomes useful as a grouping and filtering tool, using bitwise comparisons (& and |).
Dec 08, 2008 - 03:25AM

jjacek says For example, if shirts were type 1 and pants were type 2 (ignoring the rest for this example), "clothes" would be 1|2, i.e. 3
Dec 08, 2008 - 03:26AM

jjacek says And we can further group it -- if clothes is 3 and bodyparts is, say, 12, then "wearables" would be 3|12 = 15
Dec 08, 2008 - 03:27AM

jjacek says This allows comparisons using both equality (to see if the type is *exactly* something)...
Dec 08, 2008 - 03:27AM

jjacek ... or by bitwise ORing (to see if it's one of several somethings).

jjacek says This property makes it especially useful for filtering, and would actually simplify the filtering code quite a bit!

jjacek *ahem* I'm done now.
Dec 08, 2008 - 03:29AM

jjacek (Done describing it, that is -- now I have to *do* it!)

Damo Someone needs to help me gather up the pieces of my brain.. they're all over the room
Dec 08, 2008 - 03:31AM

jjacek says I warned you
Dec 08, 2008 - 03:35AM

Ali Moxie awesome, I so will not admit to following all of that
Dec 08, 2008 - 03:36AM

jjacek hopes she has the C++ skillz to pull this off.
Dec 08, 2008 - 04:32AM

CoyotePacə says 12 ?
Dec 08, 2008 - 04:33AM

jjacek asks 12 what?
Dec 08, 2008 - 05:04AM

CoyotePacə says ah, I didn't pick up that 'bodyparts' was a composite type in this example (so I was wondering why it was assigned a non-power of 2)
Dec 08, 2008 - 05:10AM

jjacek says Oh, right.
Dec 08, 2008 - 07:51AM

Tenebrous wonders how many different types there really are?
Dec 08, 2008 - 07:57AM

jjacek says Tenebrous: It depends how you count!
Dec 08, 2008 - 07:58AM

jjacek says I've defined 24 types, including 9 clothing and 4 bodyparts, visited and unvisited landmarks, online and offline calling cards, etc
Dec 08, 2008 - 12:33PM

Tenebrous thinks this is long overdue
Dec 08, 2008 - 12:34PM

Smiley thinks he is not geek enough to get that. Because he does not get that. O.o
Dec 08, 2008 - 12:59PM

Tenebrous got it so hah
Dec 08, 2008 - 01:22PM

CoyotePacə says Tenebrous probably has that curse where seeing a number like 4096 causes a little clicking sound in your head
Dec 08, 2008 - 01:25PM

Tenebrous laughs - totally!

DaleInnis wonders if jjacek knows what makes some clothes show up with generic "clothes" icon in inv, rather than shirt, jacket, pants, etc icon?
Dec 08, 2008 - 04:33PM

jjacek says DaleInnis: Well, in the code, it falls back to the generic icon if for some reason it can't figure out which specific type it is.
Dec 08, 2008 - 04:34PM

jjacek says So, I guess the asset servers forgot which type.
Dec 08, 2008 - 04:36PM

Trini thinks asset servers do not have time to forget... they're too busy losing our stuff.
Dec 08, 2008 - 07:41PM

DaleInnis says oooooo inneresting! That would explain why it's almost always really old things...
