+:I've had a look at those doors. Rather than making them invisible (what for? no one said invisible walls don't block you), I made those walls into a floor and ceiling, by swapping two pairs of vertices.
+:For the floor, I edited the AGQC accordingly. Since the now-horizontal quad still thought it was a wall, I had to (un)set the appropriate flag(s) in the bitset.
+:It looks and feels quite nice since there is a doorsill now. Wonder if pathfinding will work when the grid is fixed...
+:Is there any way to look up the ID of a quad in Oni other than by browsing '''env_highlight_gq''' values?
+:I'm interested in the quad just above the original 18454, but couldn't find it after a quick search.

 :My a priori guess would be the ONOA, and the IDXA therein. 3003 could refer to the unknown ID stored inside an ONOA.
 ::[[User:Geyser|geyser]] 20:15, 30 January 2007 (CET)
+:OK, I found where the 3003 is mapped to 3058 etc. I'd have been quicker if you hadn't flagged AKEV as "done" :P
+:Because it's in the AKEV. Well, not in the AKEV "selbst", but in its specific IDXA.
+::(but they're just ''links'', of course, so we don't consider them as unknown AKEV data, right? ^^ )
+:Anyway. The first IDXA lists the quads (AGQG, AGQC and AGQR entries) that can be turned on and off.
+:The second IDXA lists the "gunk" IDs in parallel. The same "gunk" ID can be assigned to several quads.
+:The two IDXA can be used for two-way lookup. Only gunk -> quad is used when you use '''env_show''' etc.

+:As for the ONOA, that one is related to the unknown field of the AGQG (the one which is not always 0xFFFFFFFF).
+:That field is an object ID, looked up in the ONOA. Several quads can belong to the same object (same ID).
+:The IDXA next to the ID (in the ONOA) lists the AGQG belonging to every object. So, two-way lookup.
+:The high byte of the ID is an object type. 0x05 is furniture, 0x03 is doorframe, 0x0D is trigger guide, 0x0F is console, etc.
+::[[User:Geyser|geyser]] 12:05, 1 February 2007 (CET)
+----
+I figured that out yesterday too. 0E is turret. And that's it. There're no others. The first 2 bytes are the old file ID. It's the same as in the BINA files.
+:
+Why Oni needs this file (ONOA)? Any idea. IMO Oni needs only the door entries, because if you disable them, the doors aren't any longer solid. But if I disable the other objects I can't see an effect.
+<p align=right>[[User:Ssg|Ssg]] 13:21, 1 February 2007 (CET)
+:What do you mean, "disable"? Resource, offset, new value?
+:I'm not 100% sure why Oni needs it (to look up "gunks with all their glass broken", perhaps).
+:Anyway, I find it useful because it will let us to selectively extract furniture (etc) separately from architecture.

+:
+Not really. If I'm interested in a GQ, I start Oni (debug_charas on and textures off) and look for the corner points of the GQ. With this information I look to the PNTA file (I've put the coordinates in an Excel sheet) and search for the points. When I've found them, I take the package IDs and search in the AGQG file (a Excel sheet too) for them.

+==Categorizing OBD screenshots==
+I experimentally tagged [[:Image:Abna_a.gif]] with the category "OBD data images". Does this name make sense to anyone whom it concerns? If so, I can mark that mentally as the official category for those images, and over time make sure they are categorized. Since there's a decent number of those images, I want to be 100% sure of the category name before going ahead with the rest. --[[User:Iritscen|Iritscen]] 19:07, 12 October 2008 (CEST)
