Hi guys, I know that some of you here are native german speakers. In the recent Brazilian GP of Formula 1 Sebastian Vettel let himself shout some words in German on the radio after his collision with Leclerc. Here's the video: I used google to translate the words but I need to be sure...

So guys, as some of you may have noticed I suddenly disappeared from the forum in the last weeks. Well there's a nice and curious reason. I'll make it very short and easy: I have a long time passion for Formula 1, always followed, Ferrari fan of course since the Schumacher time. With the...

Hi guys, I'm just moving the post here in a new thread since I believe that it is worth to have a bit of highlight. As anticipated I compiled a custom D3D9 with a simple function to flatten a circular area around a defined coordinate at a given altitude. A big help came from Face for both...

To be honest I think that in general if users "support" (in the sense of like more) a almost 10 year old version of a software/game instead of the latest version it is something to be concerned about. Orbiter2010P1 was surely far ahead of his time being superstable, userfriendly to approach and...

Hi guys, I'm facing a tricky task coming to the end of the VesselBuilder project. I am currently working on a Log class which which allows to log all the relevant information. I think it is absolutely a must to have as much information as possible in a log file and the experience with MS2015...

Hi guys, I think I found a bug in the function GetExhaustSpec(UINT idx, EXHAUSTSPEC* spec) and it seems to me that is present also in the other version of GetExhaustSpec. Apparently the idx the function is reading is the exhaust counter and not the ID of the exhaust: when I delete an exhaust...

Hi all, I get a compiler error LNK2019 when I use the oapiVCPosition function. Orbiter2016 official release, I have not tried in Beta. Error happens both in Debug and Release mode. Everything works, debugs and compiles fine without the use of this function so I guess there is something missing...

Hi guys, I decided to open a new thread about my current project which is the in-sim Vessel Builder for Orbiter. It all started with the ISS AtoZ unique vessel project but then I found out that it could become more complete so from a "station builder" it soon became a Vessel Builder. It is...

Hi guys, I'm facing a difficult issue that I can't find a way to solve. In the Orbiter APIs there are some defined function pointers as clbks that can be used. The first one I'm using is the LoadMeshClbkFunc used by oapiLoadMeshGlobal which is defined like this in OrbiterAPI.h typedef void...

Hi guys, you can see i'm developing in this days from the questions I keep asking here :lol: Correct me if I'm wrong: you can not change the material index of a group in a mesh at runtime, right? WHAT I AM TRYING TO DO: highlight a meshgroup, pretty much similar to what the D3D9 debug mesh...

Is there any API that I don't know about that can be called let's say "oapiReadLine(FILEHANDLE fh,char* line)" ? there is oapiWriteLine, and the APIs to read float, strings, vectors etc... but what if I want to read a general line and scan it for any value? of course I could use ifstream etc...

Hi all, I just noticed that if I need to call functions in my vessel class destructors they just don't get called... I tried also to simply log something with oapiWriteLog but nothing appears in the log... Does anyone have an idea of why? I thought that from the destructor I could call any...

Hi guys, as anticipated HERE I am currently working in a big merge of all the vessels of the fantastic ISS A to Z by Donamy and Thorston. It took me a while to make this work but now I am very close to have the possibility to have everything in just one (or a few) mesh and one (or a few)...

Hi all, Just to tell that I spotted an error in OribterApi.h. It came out because my matrix4 - vector4 multiplication was not right and I was getting crazy, so i tracked down this: from OrbiterApi.h inline VECTOR4 mul (const MATRIX4 &A, const VECTOR4 &b) { return _V ( A.m11*b.x + A.m12*b.y...

Hi guys, I'll make it very brief. I would like to build a mesh file from an existing one, but, since the original is animated, I would like to build it at the moment in which I am looking at the sim, so the animation is at a certain point. Now, I got familiar with various oapiMeshGroup...

Hi all, it is probably a silly question, but I can't find any clear explanation nor in the various topics in the forum neither in the DG... Is the nose wheel steering in orbiter applied just by differential braking? Is there any actual steering key that I can't find? In the API there is the...

All right, so I am facing a very weird situation and I need some help to understand. I need to get the force vectors of a series of vessels in the sim at each time step and to compute some additional forces to add to them. What I think I have discovered is about the use of GetForceVector 1)...

Curiously i couldn't find any thread about the movie. If there is already one, please admin forgive me and move my post into that thread! I recently watched and I loved it... I don't want to give spoilers even though we all know the story. The movie it's quite accurate even though with some...

Hi all, this is a question probably mostly for Martin but a lot of people here sure can give their point on this. I know from here: https://www.orbiter-forum.com/showthread.php?t=38762 how Orbiter computes the PMI for a superstructure made of multiple docked vessels. I think I understand the...

Hi guys, very simple. I just noticed that during flight (so no ground contact) if I sum the 4 force vectors (thrust, weight, lift and drag) and I compare it to the force I have from GetForceVector I get a difference along Z of around 50kN constant. This happens only if I apply thrust to my...
