Hi.

I'm curious to know as to why GameGuru creates dbo files when i'm using .x format?

Regards
Tony

Security, performance, legacy compatibility, annoyance factor, lot's of reasons.

The reasons above and because it's a throwback from Dark Basic and GG uses a lot of old DB code, even though it has been converted to C++. Back when FPSC was popular I purchased many FPSC models to use in DB Pro

Gameguru has barely any DB code left if any. DBO is easier to handle then X file, because it's a TGC format means they can update as they see fit, I think DBO is also a pretty raw format meaning the engine deals with it a lot faster, conversion from DBO is a lot easier then X, and rarely run into compatibility issues.

I have basically abandoned X files altogether, I only make use of FBX or DBO period, animations included I import DBO directly and do not rely on the engine to create DBO files.

There's nothing wrong with DBO files, I was just saying the dbo format is from the DB days and has been kept in as the format for GG. It's a pity they can't load into AGK out the box. As for old legacy code, not sure as I haven't looked at it, but it used to be the case that a lot of old stuff was hanging around( a lot not even used). Things have been changing at a fair pace these days though, so that may no longer be the case.

I actually adjusted my workflow, it's basically FBBO or obj-DBO, if I do animation I bypass DX entirely and go directly from a modern animating supporting format to DBO. Period, I HATE directX with a passion.

Thank you for clearing that up for me. I think i'll start using DBO files instead of .x

@Dvader-I'm looking into getting DBO's into AGK at the moment. Shouldn't be too difficult.

just a quick pic (sorry, I know it's not GameGuru related), showing an EBE structure being imported into AGK. Was converted to X format first using my DBO2X app but I will read in the DBO content inside AGK and use mesh memblocks (tier1). Unfortunately, I don't think tier 1 in AGK has any mesh memblock pointers which would have been a lot more useful. Ignore, the sphere, that will be removed.

My little AGK proggy now reads in DBO data directly and working on the meshmemblock side, so that a .X file is not needed first to load in which is what my other app does.

Bored of the Rings: Wow that is great news , the only thing is that we dont have access to animation date, so this will be for static object only. Or perhaps also make a .x export option so we could save the .x and then LoadObjectsWithChildren after

Cant wait to try this...

ah yes, I meant to add that it will only work with static meshes and will in addition add .X export option. Quite a bit to do as I'm revamping / converting current DBO2X app to AGK. Eventually for both tier2 and not just for tier1.

ok, not right yet as it's the first time I've messed with AGK meshmemblocks and doing calculations in my head so faces not correct , but it will be soon. Anyway, here is Elhumongo.DBO read into AGK and converted to (almost) meshmemblock. Once I get all this perfected, need to add the UV's of which my program can now read up to 8 UV coords from the DBO based on it's FVF size. Will see where this goes.

many thanks Cybernescence, much appreciated.

Here is another 2 pics of Elhumongo, with fixed indices, i made a small miscalculation. Also, played around with some color. Anyway, will progress onto getting the UVs to work with the actual textures. At the moment, I'm not sure how many UV coords AGK handles, I'm hoping it's more than 1. this also works wth PBR/EBE DBO's (although I need it to work with more that 1 mesh which should be relatively simple). Static objects only.

[updated-added a pic of the GG PBR dragon DBO-saved out as a meshmemblock file and reloaded back into AGK as an object and rotated. Texturing to do next after some chores.]

Added UV's to imported DBO to AGK meshmemblock (1 set for now), adding the others where needed next for staging. Also removed the culling so object now appears solid. Will test that out on a PBR/EBE type DBO. Also, need to change the name of the project to something more appropriate.

Anyway, last pic here as I didn't really want to hijack the OP's thread.

After looking thru this thread, I did a comparison on one of my "x" files versus the "dbo" file. The dbo file is less than 1/2 the size of the x file.
135 kb versus 61.5 kb. This leads me to think I should use dbo files in my fpe files in the future.

My question: Will this cause any problems?

Given this conversion, is it say to say its more preferred to use DBO files with our game packages instead of carrying over .X files as well? I'm always looking for optimization shortcuts

Also is it safe to say Game Guru doesn't actually use .X files? Just the generated DBO files from .X files?

I don't think .x files are carried over in the standalone only the dbo files and textures.

dbo files are binary, .x files tend to be text (although you can save them as binary to save space) which explains why they are bigger.

Yeah .x can be a lot smaller if saved in binary, mostly people save it in trxt format because when you embed the materials in the model its easier to exit texture references on multi texture models without putting it back throughva modelling software.

@Dvader, Preben or anyone who might be interested:

AGK code is now more flexible to work with multi FVF sizes and the AppGameKit mesh memblock stores up to 8 UV coords and any diffuse color that might be set in the DBO using uv - uv7 and color attribs. more pics and maybe source code will be attached soon all going well.

Works with Legacy, PBR and EBE type DBO's. More pics and link to the app to be posted on TGC AGK forums at some point. Maybe source if anyone wants to play around with it once code is clean/optimised.

small pic (ok not quite the last one ), shows EBE basic structure (a bit naff knocked up quickly building ), with multi UV Coords stored within multi meshes, this DBO has FVF size 56. The 1st mesh (a spikey sphere) is hidden as not added the multi mesh handling code yet but will be my next step. What I also want to do is dump out the whole of the AppGameKit Meshmemblock data for debugging and analysis (my speciality):

Source code now posted here for anyone that might find it useful, works with all types of DBO including GameGuru PBR and EBE DBOs. Multimeshes and up to 8 UV coords supported:
