I own DGSDK and darkmatter 2. I am struggling with dbloopobject and its arguments. How do I use the models from darkmatter in my app? The help shows:

void dbLoopObject ( int iObject, int iStart )
void dbLoopObject ( int iObject, int iStart, int iEnd )

How do I know where iEnd is in a model? Or, if I do not want to start at the very beginning, how do I know the different positions?

Thanx

You need to get a model viewer, a good free one used to be 3D exploration. To be honest I'm not sure if its still free or not, buyt here you can view each frame of an animation. Just go through them all an jot down the the different animations.

I'd also think darkmatter came with a list of these, but I never seen it so I could be wrong.

darkmatter models should have come with a .txt file list of all the animations for each model.

however, the easiest way is to just make a little viewer yourself!

have it display the object frame onscreen, and make it so you can step through the frames by pressing keys on the keyboard.

also if you're using TEXT (not binary) .x files, you can just open them in notepad and find all of the keyframes, down near the bottom in the "animation" section.

I don't own any of the DarkMATTER packages (yet) but I noticed
that the "miko" model that come with the dgSDK samples (used in the "camera" demo) has a >anim.txt<. Unfortunately, therein you will find the keyframes only... but dgSDK commands like dbLoopObject need the "real" frame.

Now, how can you "convert" these keyframes into frames?
(so you can use it with dgSDK without to go trough all the frames)

Or do I miss a point?

[edit]
btw, I have coded a simple viewer where you can go trough the frames.. along with a cameraclass.
PM me if you would like the code.
(I will post the source to the codebase anyway when the cameraclass is a kind of final)

"... but dgSDK commands like dbLoopObject need the "real" frame."

I am not sure about that but when I use the numbers provided in the text file.. like 0..59 then it play only a very short sequence of the animation.
I need to play the frames 0..~15000 to get that first animation.

I am a little bit confused now o_O

I think you may be on to something. In my code I see the following:

dbLoopObject(2); // appears to work
dbLoopObject(2, 150); //also appears to work
dbLoopObject(2, 150, 650); //does not do anything-- object stands still

the text file that came with my DarkMatter animation states:
000 : Stance
000 - 080 : Idle Posture
080 - 150 : Fidget Animation
150 - 200 : Attack (170 Impact)
200 - 250 : Hurt (220 Impact)
250 - 300 : Block/Dodge (270 Impact)
300 - 350 : Stagger
350 - 400 : Collapse/Die (370 Impact)
450 - 500 : Get Up
450 - 550 : Walk
: 450-470 - Position To Loop
: 470-530 - Looping Walk
: 530-550 - Return To Stance
550 - 650 : Run
: 550-570 - Position To Loop
: 570-630 - Looping Run
: 630-650 - Return To Stance

Try dbLoopObject(2, 550,650);

P.S.
Which actor are you trying to use?

I just found this in another thread (about the Dungeon demo).
In the Dungeon Demo, they use something like this:
dbLoopObject ( baddie [ iLoop ].obj , 0 , 80*160 )
So it seems that you have to use a multiplier for some models.

When I am back at home, I will try to multiply the values from the text file.
Hopefully this will do it with the "Miko" model.

(*notes* "add public memberfunction "set/get_fAniMultiply" to the XModel-class")

I am using Female Crew.X from DarkMatter 2. I tried your suggestion of trying
dbLoopObject(2, 550, 650);
This did not move the object at all.

Smithy is on to something with his multiplier theory. Modifying my code to:
dbLoopObject(2, 550, 650*80);
caused my object to move, but not the expected running. Looks more like the impact...

Is there any documentation about this anywhere? I bought the book and there does not appear to be anything about this in it either....

What blows me away, is that I am currently using DGSDK and I have at least 3 animated models moving around right now in my own project. And for the life of me, I am not sure what your problem is (it's not an insult to you, I believe you, but I just don't get what's wrong).

I don't have "DarkMatter 2" but I do have the actors they use (http://www.geo-metricks.com) and I will try with the same actor to help you find your issue.

Hopefully we can solve this problem which has been plaguing you for awhile now.

P.S.
Post the code you are using por favor.

Well, I was struggling with how to get an example of my problem. I cannot/will not post one of the DarkMatter object as that will violate my license (and common sense). Instead, I am using the example model (miko) that came with the DGSDK. For my example, I want miko 'Running Slash With Blade (Arc). Only that. Looking at the txt file Anims.txt as (excerpt)follows:

Anims
.
.
214 - 224 : Running Slash With Blade (Arc)
.
.

So my dbLoopObject() call looks like:

dbLoopObject(2,214,244);

When I do this, I get no movement....
Code for this is follows... If you run this app and you see miko run, I am going to do what my mother always wanted and get out of computer business and join a seminary!

I am still confused by what is going on here. Does anyone have any insight as to how to animate a .x object correctly based on the text file supplied with the object?

thanx
