Problem Spacecraft3 payload jettison while landed

[Michael_Chr]

While writing an SC3 ini file for a lunar lander I have come across a problem/feature with the SC3 module. I'm creating a lunar lander that carries its acsent vehicle as a payload according to the SC3 documentation. Whilst on the surface after landing and jettison of the acsent vehicle payload now the new vessel is not spawned at the position where the payload mesh were but in the centrepos of the vessel it was spawned from.
I have tried jettisoning it in orbit and there the vessels spawn at the correct position - so in that respect it works....
Anyone else come across this problem???
Any ideas to fix it...???
UCD is an option...but if for no other reasons I would prefer to refrain from that since it creates havoc with the CG vs. RCS use (You can gather that my payloads are a bit offcentered
I guess most of the times that new vessels are spawned from landers they sit on top of the landing vehicle - hence the spawningt point is not an issue...my payload however sits in front. of the lander.

You could maybe reverse engineer what the FOI team did with their Poderosa II, and the HLV lander from Jekka and Momo. AFAIR both of them have landers that do what you are wanting to do.

When you jettison a payload, it should just fall to the ground.

 

[PhantomCruiser]

Yeah. I was thinking if the touchdown points were modified; that when jettisoned it would appear to be in the same spot, just no longer be part of the "mother" craft.

 

[Michael_Chr]

In both cases their landers were designed to be spawned in the same position as their mothership i.e. on top of them. (the Height can be adjusted via the landing points). I tried with HLV module to offset the payload (mesh statement) but when jettison occurs on ground the spawned vessel shows up where the centre of mesh of the mother ship is. I even tried to "nudge" a spawned vessel by adding some speed but it is recognized that the ship from the start is on the surface - hence all speed additions are ignored.
As a crude way of fixing this I was thinking about offsetting the entire mesh to accomodate for this - but I guess that wont work since I cant offset thrusters and CG.
So I guess I'm back to using UCD for it to work.

 

[Donamy]

I'm confused. You don't want the landing points, to be on the ground ?

 

[Michael_Chr]

I'm confused. You don't want the landing points, to be on the ground ?

What I'm after is that the "payload" vessel spawns where its mesh was previously defined as a payload on the "mothership".

Pictures explains it better than words
This is the situation where the payload has not been "jettisoned".

The cabin part to left of the entire vehicle is the payload.
This is what happens when I jettison that payload.

As you can see the new vessel is spawned at the (0,0,0) position relative to the mothership on the ground and not at the offset position where I had placed the payloadmesh.
The interesting part is that when in orbit the vessel is spawned at the position of the original mesh.
But is there a solution to spawn a vessel at an offset position ?
It seems that Vinka did not include the payload "offset" check when a SC3 vessel is landed. All other SC3 addons I have checked exhibits same behavior but its not a problem for them since their payloads shall spawn in the (0,0,0) pos of the mother ship (Altair, Apollo LM, HLV, Poderosa etc.)

Hope this explains it better - every bit of advice would be deeply appreciated

ps. I want spawned vessel to be in a landed state i.e. the landing points on the ground. I have adjusted the Y value of the landing points to cater for this.

 

[BrianJ]

Hi,
I suspect the "spawn-payload-at-mothership-origin(0,0,0)-if-landed" is spacecraft3.dll bug.
Tried it with Rosetta/Philae while landed and exactly same bug happens.

Only workarounds I can think of are:
1) Have payload already present in scenario, attached or docked to mothership.
2) Add docking ports to payload and mothership so that when payload is spawned it immediately docks to mothership - but you must spawn payload BEFORE landing.

Cheers,
Brian

I think it will crash, if you have 2 vessels docked at landing (Orbiter bug).

I think it's a configuation from launch to landing. Ttry changing the configuration in the scenario.

One thing I remember what I did for the Jason lander, was to add a dummy mesh, that the Jason was attached to for tail sitting, while landed which had the touchdown points turned 90 deg. After launch it was unattached for the Jason to be able to land on it's wheels.

You're right Don. Forgot about that. Cheers.

Thanks for your inputs Brian and Don...its really appreciated

I have thought about this but can you activate a dummymesh within the confines of SC3?

Maybe an animation of some kind?

I could also offset either(mothership or payload) of the meshes - but that would create problems with thrusters cg etc...???

I would suspect I would need to code the vessel as a module then which I'm not capable of. On the other hand I'm seriously considering writing out in this forum for help with coding this and making it a real dll instead of making it as an SC3 vessel.

Basically, I created an invisible Jason as a tail sitter, with all the correct thrusters, and attached the regular Jason to it.

where you please get this spaceship from: Hydra?

where you please get this spaceship from : Hydra
Thank you.

greeting

 

[PhantomCruiser]

I think it's something that he is making on his own. Looks pretty awesome so far.

 

[Michael_Chr]

Hydra...Its a creation I'm working on these days. A Lunar Lander ... a little like an Altair on steriods. What you see is only ½ of it. A habitation module goes inside all that framing. It holds a LER on the aft end for drop off after Descent. In the front is the ascent stage. It has dimensions to fit inside an 8.5 meter diameter fairing for Launching - So an SLS or Quasar can launch it (but most likely only that ).
Some of the meshes and textures are more or less borrowed from other authors so I have to get their permision first before I can go public with it...but first I need a finished product

 

[funkheld]

hello, thanks.

greeting.
