Advanced Question Creating vessels and interacting with them

gattispilot · Jun 8, 2013

A couple of questions so Hope someone can help.

I am trying to create 6 new vessels. Then attach them to the mother vessel and from the mother ship interact with a module.
This is the code I am using to create the 6 vessels. But I get a CTD right now. If only create 1 vessel then no CTD.

Code:

void LEONOVOEXT::Airbag_Check()
{
OBJHANDLE airbag;

  VESSELSTATUS2 vs;
  vs.version = 2;
  GetStatusEx (&vs);
   VESSEL *airbag_vessel;
ATTACHMENTHANDLE airbag_attach;     
if (airbag_created == 0 && airbag_jettison == 0)
{ 
  
        airbag = oapiCreateVesselEx ("Airbag1", "leonovairbag1B", &vs);
        airbag = oapiCreateVesselEx ("Airbag2", "leonovairbag2B", &vs);
        airbag = oapiCreateVesselEx ("Airbag3", "leonovairbag3B", &vs);
        airbag = oapiCreateVesselEx ("Airbag4", "leonovairbag4B", &vs);
        airbag = oapiCreateVesselEx ("Airbag5", "leonovairbag5B", &vs);
        airbag = oapiCreateVesselEx ("Airbag6", "leonovairbag6B", &vs);
//airbag_vessel = oapiGetVesselInterface (airbag);
//airbag_attach = airbag_vessel->GetAttachmentHandle (1, 0);
//AttachChild (airbag, BAG1, airbag_attach);


airbag_created =1;
}   }

cfg for leonovairbag1B

Code:

; === Configuration file for vessel class DeltaGlider ===
ClassName = leonovairbag1
MeshName = leonovairbag1
;Module = LEOAIRBAG

So once they are created then attach to the mother ship.

Are leonovairbag2B.cfg, leonovairbag3B.cfg, leonovairbag4B.cfg, leonovairbag5B.cfg, leonovairbag6B.cfg vessel configuration files which you use to create the vessels defined the same way?

SolarLiner · Jun 8, 2013

Why do 6 cfg ? If they are the same, just do a "leonovairbar" vessel class and apply it to all of your 6 bags.

gattispilot · Jun 8, 2013

no
They are different. Because they use different meshes

Code:

; === Configuration file for vessel class DeltaGlider ===
ClassName = leonovairbag2
MeshName = leonovairbag2
;Module = LEOAIRBAG

; === Configuration file for vessel class DeltaGlider ===
ClassName = leonovairbag3
MeshName = leonovairbag3
;Module = LEOAIRBAG

;Module = LEOAIRBAG

So why nott add them as separate meshes in your vessel, then work on each as needed? If I follow correctlyy, you're tryying to create a rover that lands by airbag like the MER-2003 rovers?

gattispilot · Jun 8, 2013

What I need to do is created the 6 airbags and attach to certain points.

Code:

BAG1 = CreateAttachment (0, _V( -1.8, 0.1, -19.53), _V( 1, 0, 0), _V(0, 1, 0), "air", 0);
BAG2 = CreateAttachment (0, _V( 1.8, 0.1, -19.53), _V( 1, 0, 0), _V(0, 1, 0), "air", 0);
BAG3 = CreateAttachment (0, _V( -0.6, 2.0, -19.53), _V( 0, 1, 0), _V(0, 0, 1), "air", 0);
BAG4 = CreateAttachment (0, _V( 0.6, 2.0, -19.53), _V( 0, 1, 0), _V(0, 0, 1), "air", 0);
BAG5 = CreateAttachment (0, _V( 0.6, -1.8, -19.53), _V( 0, 1, 0), _V(0, 0, 1), "air", 0);
BAG6 = CreateAttachment (0, _V( -0.6, -1.8, -19.53), _V( 0, 1, 0), _V(0, 0, 1), "air", 0);

The the ;Module = LEOAIRBAG is a separate module that then scales the airbags.

They need to be separate vessels as they then can be detached

HCLV loads all LRB meshes into single vessels and then spawns them as separate vessels on separation while hiding those attached to launcher.

gattispilot · Jun 8, 2013

What is HCLV and is it code available? I don't understand why if more than 1 vessel created then a CTD

Hlynkacg · Jun 8, 2013

You have 1 object handle for 6 objects. This is bad juju.

For a working example see my Apollo Application Project's source code, specifically the CSM's SLA separation routine.

Loru · Jun 8, 2013

HCLV Hyperion is a heavy launch vehicle in developement by me and Woo482. It uses for single LRB mesh to display all 2 or 4 LRBs and on separation spawns 2-4 LRB vessels handled by second module from point/time of spawning.

Thanks. where is the code sample?

Code:

OBJHANDLE airbag;
OBJHANDLE airbag1;
OBJHANDLE airbag2;
OBJHANDLE airbag3;
OBJHANDLE airbag4;
OBJHANDLE airbag5;
  VESSELSTATUS2 vs;
  vs.version = 2;
  GetStatusEx (&vs);
   VESSEL *airbag_vessel;
ATTACHMENTHANDLE airbag_attach;     
if (airbag_created == 0 && airbag_jettison == 0)
{ 
  
        airbag = oapiCreateVesselEx ("Airbag1", "leonovairbag1B", &vs);
        airbag1 = oapiCreateVesselEx ("Airbag2", "leonovairbag2B", &vs);
        airbag2 = oapiCreateVesselEx ("Airbag3", "leonovairbag3B", &vs);
        airbag3 = oapiCreateVesselEx ("Airbag4", "leonovairbag4B", &vs);
        airbag4 = oapiCreateVesselEx ("Airbag5", "leonovairbag5B", &vs);
        airbag5 = oapiCreateVesselEx ("Airbag6", "leonovairbag6B", &vs);
//airbag_vessel = oapiGetVesselInterface (airbag);
//airbag_attach = airbag_vessel->GetAttachmentHandle (1, 0);
//AttachChild (airbag, BAG1, airbag_attach);


airbag_created =1;
}   }

tried this and still ctd no log info

Download AAPO (See link in sig) Open the source code folder, open the CSM's source file and find the Spacecraft Launch Adapter's separation routine.

void CSM::AdapterSep (void)

Try setting vs.flags to zero.

gattispilot · Jun 8, 2013

like this:
vs.version = 0;
Still CTD

Face · Jun 8, 2013

gattispilot said:

No, like this:
vs.flag=0;

Of course in addition to vs.version = 2;

gattispilot · Jun 8, 2013

Code:

OBJHANDLE airbag;
OBJHANDLE airbag1;
OBJHANDLE airbag2;
OBJHANDLE airbag3;
OBJHANDLE airbag4;
OBJHANDLE airbag5;
  VESSELSTATUS2 vs;
  vs.version = 2;
  GetStatusEx (&vs);
  vs.flag=0;
   VESSEL *airbag_vessel;

still CTD

   VESSEL *airbag_vessel;

still CTD

Please try it BEFORE using the structure, i.e. before calling GetStatusEx. The flag parameter also controls the getter options.

gattispilot · Jun 8, 2013

Thanks. now created. But how to attach.

Code:

{
      
OBJHANDLE airbag;
OBJHANDLE airbag1;
OBJHANDLE airbag2;
OBJHANDLE airbag3;
OBJHANDLE airbag4;
OBJHANDLE airbag5;
  VESSELSTATUS2 vs;
  vs.version = 2;
  vs.flag=0;
  GetStatusEx (&vs);
 
   VESSEL *airbag_vessel;
ATTACHMENTHANDLE airbag_attach;     
if (airbag_created == 0 && airbag_jettison == 0)
{ 
  
        airbag = oapiCreateVesselEx ("Airbag1", "leonovairbag1B", &vs);
        airbag1 = oapiCreateVesselEx ("Airbag2", "leonovairbag2B", &vs);
        airbag2 = oapiCreateVesselEx ("Airbag3", "leonovairbag3B", &vs);
        airbag3 = oapiCreateVesselEx ("Airbag4", "leonovairbag4B", &vs);
        airbag4 = oapiCreateVesselEx ("Airbag5", "leonovairbag5B", &vs);
        airbag5 = oapiCreateVesselEx ("Airbag6", "leonovairbag6B", &vs);
airbag_vessel = oapiGetVesselInterface (airbag);
airbag_attach = airbag_vessel->GetAttachmentHandle (1, 0);
AttachChild (airbag, BAG1, airbag_attach);


airbag_created =1;
}   }

Not sure where it gets the child airbag info.

I uncommented in the CFG to allow the module to be airbag.

in the cpp of the airbag module I think is where the child attachment is.

Code:

if (_stricmp (GetName(), "airbag1") == 0 || _stricmp (GetName(), "airbag2") == 0)
CreateAttachment (1, _V(0, 0, 0), _V(1, 0, 0), _V(0, 1, 0), "Leonov", 0);
else
CreateAttachment (1, _V(0, 0, 0), _V(0, -1, 0), _V(0, 0, 1), "Leonov", 0);
}

If you have not defined an attachment point/handle for your airbag that would be the cause of the ctd.

---------- Post added at 12:42 ---------- Previous post was at 12:36 ----------

I also suspect that AAPO's parachute and drogue code would be highly useful to you.

gattispilot · Jun 9, 2013

Thanks. I think we may just create the vessels in the scenario editor and attach. But how can I control them from the one mother ship.

In the airbag module. It looks like it gets

Code:

if (bagdoor_operate >= 2 && airbag_jettison == 0)

from the mothership.

Code:

#ifndef __POD_H
#define __POD_H

#include "orbitersdk.h"

#define DLLEXPORT __declspec(dllexport)
#define DLLIMPORT __declspec(dllimport)

//Leonov shared data
DLLIMPORT double bagdoor_proc;
DLLIMPORT int bagdoor_operate;
DLLIMPORT int airbag_jettison;

VESSELSTATUS2 vs;

class Airbag: public VESSEL {
public:
Airbag (OBJHANDLE hObj, int fmodel);
~Airbag ();
