Confused. Looking at actual images of the DM facing towards the shuttle. It appears the dock rotates? See on the view of the shuttle in sts 74 fin #3 is aligned with the keel support. But in sts 79 the docking ring is offset?
@DaveS any ideas?

 

[GLS]

The STS-74 image obviously shows the Mir-side of the DM.

Thanks. That solves that. Now to figure out the issue with the moving dock

 

[gattispilot]

The dock alignment is correct. But the moving dock with the docking Module with a 30 degree offset causes issues. I tried docking with DarkEnergy and the same issue. Not if there is a fix.

 

[gattispilot]

I am not sure why the spin. All it is doing is undock and dock

//move ods dock void Atlantis::DoIDARing() { if (TUNNELODS == 1) { VECTOR3 new_dock_pos = _V(-0.042, 2.2250, 8.2264);; new_dock_pos.y += (soft_capture_ring_proc * 0.4);//0.45 OBJHANDLE v = GetHandle(); int idx = 0; // dock index OBJHANDLE docked_ship = GetDockStatus(GetDockHandle(0)); // object handle of docked vessel if (docked_ship != NULL) // make sure handle is valid, if it is... { VESSEL* docked = oapiGetVesselInterface(docked_ship); // get VESSEL interface for docked vessel int dcount = docked->DockCount(); // get number of docking ports for (int i = 0; i < dcount; i++) // Cycle through ports { if (docked->GetDockStatus(docked->GetDockHandle(i)) == GetHandle()) { idx = i; docked->Undock(idx, 0); //SetDockParams(hDockODS2, new_dock_pos, _V(0, 1, 0) , _V(0, 0, -1)); //sprintf(oapiDebugString(), "SHUTTLE_DOCKDIR.x %lf SHUTTLE_DOCKDIR.y %lf SHUTTLE_DOCKDIR.z %lf SHUTTLE_DOCKROT.x %lf SHUTTLE_DOCKROT.y %lf SHUTTLE_DOCKROT.z %lf", SHUTTLE_DOCKDIR.x, SHUTTLE_DOCKDIR.y, SHUTTLE_DOCKDIR.z, SHUTTLE_DOCKROT.x, SHUTTLE_DOCKROT.y, SHUTTLE_DOCKROT.z); docked->Dock(v, idx, 0, 0); } } //} } } }

 

[diogom]

Have you tried using Dock(v, idx, 0, mode) with mode 1 or 2?

 

[gattispilot]

Yes. Same result. It seems the dm docking values?
CreateDock(_V(-0.042, 0, 2.136), _V(0, 0, 1), _V(0, -1, 0)); MIR CreateDock(_V(-0.006, 0.000, - 2.125), _V(0, 0, -1), _V(0.500011, -0.866019, 0)); Shuttle

If I dock with MIR docking port no issues.



void Atlantis::DoIDARing() { //sprintf(oapiDebugString(), "new_dock_pos.y %lf soft_capture_ring_proc %lf ", new_dock_pos.y, soft_capture_ring_proc); if (TUNNELODS == 1) { VECTOR3 new_dock_pos = _V(-0.042, 2.2250, 8.2264);; new_dock_pos.y += (soft_capture_ring_proc * 0.4);//0.45 OBJHANDLE v = GetHandle(); int idx = 0; // dock index OBJHANDLE docked_ship = GetDockStatus(GetDockHandle(0)); // object handle of docked vessel if (docked_ship != NULL) // make sure handle is valid, if it is... { VESSEL* docked = oapiGetVesselInterface(docked_ship); // get VESSEL interface for docked vessel int dcount = docked->DockCount(); // get number of docking ports for (int i = 0; i < dcount; i++) // Cycle through ports { if (docked->GetDockStatus(docked->GetDockHandle(i)) == GetHandle()) { idx = i; docked->Undock(idx, 0); SetDockParams(hDockODS2, new_dock_pos, _V(0, 1, 0), _V(0, 0, -1)); docked->Dock(v, idx, 0, 0); } } } else { SetDockParams(hDockODS2, new_dock_pos, _V(0, 1, 0), _V(0, 0, -1)); } } }


When the scn starts I can kill the angular rotation of the shuttle but then it starts back up

 

[diogom]

So the thing is, as the ring retraction plays out and it undocks and docks, it induces angular rotation on the shuttle+DM? I had somehow understood it was the docking module's docked angle which was changing.

Yes. Because the docking module alignment is 30 degrees off center. It causes the angular rotation

 

[diogom]

I don't recall if I had trouble with angular motion, but I did have an issue where each time it docked, the orbit would change, over the whole sequence it added up to quite a bit. The "teleportation" probably disturbs a few things. Try using GetAngularVel before undocking and SetAngularVel after redocking with the same vector. For the orbit thing, I had to do similar with Get and SetElements.

 

[gattispilot]

I wonder if I have the dock on the mesh correct. I have it matched to the drawing/ images. It looks to align with the shuttle the docking module needs to be 30 degrees offset.
Any thoughts? @DaveS @Max-Q

 

[gattispilot]

Rethinking the docking module.

Here is STS 76. As you can see fin 3 of the DM is along the z axis. Maybe the dock is 0,0,-1 but the mesh is rotated 30 degrees?

 

[gattispilot]

The docking Module mesh is correct. To dock with the shuttle. the docking Module has to be rotated 30 degrees

Here the DM mesh is rotated 30 degrees

 

[gattispilot]

Trying to get the new moving dock code to work. But have another issue. I can't seem to find what is happening.

For the dock ring animation I have this:
if (TUNNELODS == 1) {//ODS is present if (APAS_status >= DOCK_RAISING) { double da = simdt * .1; if (APAS_status == DOCK_RAISING) { if (soft_capture_ring_proc > 0.0) soft_capture_ring_proc = max(0.0, soft_capture_ring_proc - da); else APAS_status = DOCK_UP; } else { if (soft_capture_ring_proc < 1.0) soft_capture_ring_proc = min(1.0, soft_capture_ring_proc + da); else APAS_status = DOCK_DOWN; } SetAnimation(anim_DOCKRING, soft_capture_ring_proc); //SetAnimation(anim_rods, soft_capture_ring_proc); CalculateRodAnimation(); //DoIDARing(); } }
enum APAS_status { DOCK_UP, DOCK_DOWN, DOCK_RAISING, DOCK_LOWERING }APAS_status;

void Atlantis::RevertDockingRing(void) { APAS_status = ((APAS_status == DOCK_UP || APAS_status == DOCK_RAISING) ? DOCK_LOWERING : DOCK_RAISING); }
APAS_status = DOCK_UP;
where is where it is saved:
sprintf(cbuf, "%d %0.4f", &APAS_status, &soft_capture_ring_proc); oapiWriteScenario_string(scn, "DOCKAPAS", cbuf); and read:
else if (!_strnicmp(line, "DOCKAPAS", 8)) { sscanf(line + 8, "%d%lf", &APAS_status, &soft_capture_ring_proc); }

The scenario starts out:DOCKAPAS 0 0.0000
and run the scenario and not pressing any keys
I get this:
DOCKAPAS 385911332 0.0000

 

[diogom]

I think when you pass &APAS_status to sprintf, you're actually saving the address, not the value, hence the weird number. Same would go for the proc, curious that it's saving 0 anyway, though I think it might be expecting a float (%0.4f) when proc is I'm assuming a double (lf), dunno if that trips it up.

Thanks

But all these work
else if (!_strnicmp(line, "PETD", 4)) { sscanf(line + 4, "%d%lf", &PETD_status, &PETD_proc); }
works
sprintf(cbuf, "%d %0.4f", EXT_status, EXT_proc); oapiWriteScenario_string(scn, "HATCH", cbuf);
enum APAS_status { DOCK_UP, DOCK_DOWN, DOCK_RAISING, DOCK_LOWERING }APAS_status; should be a single digit 0=dock up,.....

It seems to be good until it saves it.

So I added breaks to see where it was changed.

and at is good by the end of this when I exit;
void Atlantis::clbkSaveState(FILEHANDLE scn) {
Not sure what function is next to put a break?

 

[gattispilot]

Fixed the save state of the docking ring.
UGH
sprintf(cbuf, "%d %0.4f", APAS_status, soft_capture_ring_proc); oapiWriteScenario_string(scn, "DOCKAPAS", cbuf);

I need to better align the dock. But the moving dock works. I get a CTD when I undock though

 

[gattispilot]

Thanks to @Max-Q and @diogom I got the moving dock to capture the Docking Module and lower to the shuttle. The scn starts and you grab the DM and move into position,

 

[gattispilot]

Because there are 2 docks position. I just show which mesh and set the dock position. But. I need to see if I can use the same mesh so that the animation remains the same. And then have. ODSmesh show up at x,y,z position. And just change the XYZ position.

On the dock alignment. As I understand. The ODS mesh fits on top of the external airlock. So mesh alignment. then adjust the dock so that the docking target aligns with the crosshairs, right

It is said that the shuttle's payload bay is designed to be that long so that they could carry KH-9 (Hexagon) spy satellites into polar orbits from VAFB. From the article, The HEXAGON and the Space Shuttle
