Project Newly developed JD rocket

MJR · May 13, 2009

I am currently modeling a rocket. It is a beta right now though. The only thing is that I am not sure what needs to be in the config. file and how to calculate it. The reason why I ask this because there are so much parenthesis and underscores in the config files that I don't know where to put it. Also, what do I save it as after I am done making it in Orbiter?

Brad · May 13, 2009

Are you doing this via a DLL or using spacecraft or multistage? If the later check out the excellent tutorial from ar81 on orbiterhanger.

MJR · May 13, 2009

I guess spacecraft for now because I haven't made second stage.

By the way, I halted on my addon development that is why I don't remember much.

So it should help in the development of the ini. and config. files?

It looks like you should change MESHNAME = "JD" to MESHNAME=JD (remove quotes)

tblaxland · May 14, 2009

You also need to change your ship name in the scenario file to:

Code:

JD:Spacecraft\Spacecraft3

MJR · May 14, 2009

Is is too small? I think it is.

---------- Post added at 11:36 PM ---------- Previous post was at 11:32 PM ----------

It keeps saying that the mesh is not found.

Is what too small? Did you change the name like I said?

liber · May 14, 2009

If you still have trouble check this file.
It's playable add with JD name.
Carefull if you try it you may overwrite your JD add...
You could use this as example for spacecraft and how to proper named ini file,mesh,scenarios...

It is working. It just doesn't have thrust. The config looks like this.

ar81 · May 14, 2009

You only defined main thrust, not attitude thrusters.
See some tutorials here.
When adding thrusters you need to add two sets of data:
-Data on thrust force ([CONFIG] section)
-Data used for visuals of the thruster

Use Orbiter diagnostic V0.2 to check for missing files and inconsistencies that could lead you to a crash.

MJR · May 14, 2009

Is this good? I added attitude.

You added the force, but visuals have some missing data.
Check the tutorial on parameters, see all commands involving thrusters.
Spacecraft.dll allows a max of 16 thrusters if I am correct (I mean visuals). Check Spacecraft docs and check it out.
The tutorials I made gather all the knowledge I have on spacecraft.dll.
The rest is about experimenting and finding other great many things I might have missed.

MJR · May 15, 2009

Ok. I have everything done. The thrusters are in the wrong position though. Here is the files. An help on it?

Also, how do I change the rockets posititon to face upward? I think I exported it wrong on Anim8or while it was on its side. BTW, do I iput the main thruster on top of the x axis or no?

liber · May 15, 2009

Rotate in anim8tor object like you see on photo...so nose facing up in side view.

Urwumpe · May 15, 2009

liber: That is not needed when using the export script for anim8or I have written. You just have to pay attention that it only supports one material per mesh.

OK. Sorry but I don't use script...

Does script convert to orbiter mesh from anim8tor?
I use Msh_MakerV2 for conversion to mesh.
Where could I get script and tutorial for it?

liber said:

Yes, it does direct export from anim8or.

liber said:

From O-H, tutorial is not much needed, you just need to make sure it loads on anim8or start (By placing it into the script folder you have selected in the anim8or configuration, usually the same folder as anim8or).

http://orbithangar.com/searchid.php?ID=2698

If loaded on startup, you should see the Orbit mesh format in the export dialog.

Orbiter 2024 has been released!
