CptSmiley Posted October 30, 2012 Share Posted October 30, 2012 Hey guys, So I'm try to dynamically alter the mass and inertia of the aircraft using the ed_fm_change_mass() function, however it locks up the sim when I utilize this function (return true to say I changed the mass and/or inertia). If I return false it works fine but obviously doesn't change my mass/inertia. It even crashes still when I set all the delta's to 0 but still return true. Any ideas? "Witness mere F-14s taking off from adjacent flight decks, gracefully canting left and right, afterburners flaming, and there’s something that sweeps you away—or at least it does me. And no amount of knowledge of the potential abuses of carrier task forces can affect the depth of that feeling. It simply speaks to another part of me. It doesn’t want recriminations or politics. It just wants to fly.” ― Carl Sagan Link to comment Share on other sites More sharing options...
Tango Posted October 30, 2012 Share Posted October 30, 2012 You got me wondering how you got the AFM API. It's in the dev build of the sim, but not in any public release AFAIK. You are going to find it extremely hard to get support for this until you are a 3rd Party Developer. None of us can say anything as we are under NDA. Best regards, Tango.

SkateZilla Posted October 30, 2012 Share Posted October 30, 2012 umm isnt the API in a root/DCS World/ folder?

Why have a How To forum if no one can help?

SkateZilla Posted October 30, 2012 Share Posted October 30, 2012 I know I have the API in one of the Eagle Dynamics/DCS World/ folders... Maybe the version left in 1.2.1's folder is older or incomplete compared to the version the 3rd party devs have? But yeah, This trend of asking a question, Followed by crickets, Then losing a night's sleep experimenting and figuring it out for ourselves is getting a bit ....Tiring? I Guess....

Krebs20 Posted October 30, 2012 Share Posted October 30, 2012 (edited) Keep asking questions. The problem right now, people in the know may not be able to anserwer you. If you can get your 3rd party, as Tango said, you may or may not get some anserwers. Am I vauge enough?

But maybe it's for our own benefit. We were the first 3rd Party with a working AFM. Who helped us? ;) But I get your point. Remember, we are competitors as well as developers, so there are things we know that can't be shared for other reasons, talk of NDAs aside. Best regards, Tango.

It has nothing to do with "not honoring an NDA" but why have a HowTo forum when nothing can be talked about, should just make it private. That or tell me what I can or can't ask. Thanks!

SkateZilla Posted October 30, 2012 Share Posted October 30, 2012 I think he meant we shouldnt be discussing this or trying to get answers on the open forums and that if we sign a NDA and get a license and access to the 3rd party stuff they'll help us there?

The problem is not what you can ask, but what we can say (which isn't much). You are the only team outside of the 3rd Party Devs who are trying to build an AFM, AFAIK. I'm not even sure the AFM SDK should be publicly available. I'm in an interesting situation in that I work with TWO dev companies, so I have to be even more careful than I already had to be. I work with both the Virtual Patriots and VEAO Ltd. As I'm sure you can appreciate, that means I'm privvy to a lot more than if I just worked with one team. Best regards, Tango.

Understood, how would one even get approved to be a 3rd party dev if they haven't first proven coding competency to write an AFM in the first place? That was my reasoning behind why they might have made some form of the AFM API available publicly.

Maybe we're setting Proof of Concept Bar a bit high or over understanding it's definition, As we want it to be a pretty much Fully functional Module that needs just to be tweaked w/ assistance. and we wanted a 100% working AFM to submit as PoC for AFM Coding.

Tango Posted October 30, 2012 Share Posted October 30, 2012 All I can say is that the requirements to become a 3rd Party Dev are different from creating a product under the DCS brand. Do what you need to do to get 3rd Party Dev status. Best regards, Tango. Link to comment Share on other sites More sharing options...
CptSmiley Posted October 30, 2012 Author Share Posted October 30, 2012 As an aside to the weights/moments of inertia thing. Since weight force and moment of inertia are done automatically by DCS, and the fact that there are no inertia variables in the lua config. How does DCS determine the moment of inertia of the aircraft? Does it take the lua provided weight, the length, height, span, etc.. and calculate the inertias by distributing mass evenly? I'm just curious if it is estimating the moments of inertia for my F-16 correctly or closely.

aaron886 Posted October 31, 2012 Share Posted October 31, 2012 Sounding a bit pretentious, here, Tango. ;) The EFM (not AFM) "API" is publically available in 1.2.1, and a template file is included with the release client. Link to comment Share on other sites More sharing options...
SilentEagle Posted October 31, 2012 Share Posted October 31, 2012 (edited) Without bothering to read the whole thread, I can tell you third party status doesn't get you the answers to your questions. I have had the same three questions about the EFM (one of them involves fm mass) for three months now. I believe ED devs are much too busy with FC3 and such at the moment. Tango may be under NDA for his involvement with VEAO projects, but I am not, as we do not have a formal contract with our L-39. Considering the fact that ED released the flight model API with the latest public release, I can't see why there should be any secrets about it. This section of the forum already has members with way more API understanding than was conveyed to third parties at its release.

Cedaway Posted October 31, 2012 Share Posted October 31, 2012 I'm neither dev nor informatician but I consider it's amazing how the community CAN interact to develop and share the knowledge about the 'under the hood' of the sim. It's kind of 'positive emulsion' here around. OK, there is NDA things that is a serious thing but anyway, some member are f*** talented and CAN actually make this sim better. I find it amazing.

ED Team Alex Okean Posted October 31, 2012 ED Team Share Posted October 31, 2012 (edited) Hey guys, So I'm try to dynamically alter the mass and inertia of the aircraft using the ed_fm_change_mass() function, however it locks up the sim when I utilize this function (return true to say I changed the mass and/or inertia). If I return false it works fine but obviously doesn't change my mass/inertia. It even crashes still when I set all the delta's to 0 but still return true. Any ideas? if nothing change you need return false. once again according to template /* Mass handling will be called after ed_fm_simulate : you should collect mass changes in ed_fm_simulate double delta_mass = 0; double x = 0; double y = 0; double z = 0; double piece_of_mass_MOI_x = 0; double piece_of_mass_MOI_y = 0; double piece_of_mass_MOI_z = 0; // while (ed_fm_change_mass(delta_mass,x,y,z,piece_of_mass_MOI_x,piece_of_mass_MOI_y,piece_of_mass_MOI_z)) { //internal DCS calculations for changing mass, center of gravity, and moments of inertia } */ keyword for this is "WHILE" while you return true it will try to change mass why i use loop for it : mass changing can be in various places of aircraft and various reasons : for example geeting fuel pump move fuel from one tank to another . it is two actions : remove mass from one tank , add to another typical using of ed_fm_change_mass should be : in ed_fm_simulate you collect mass changes to stack like structure : std::list<mass_changes> *changes_; .. changes_.push_back(change_one); changes_.push_back(change_another); bool ed_fm_change_mass *(double & delta_mass, double & delta_mass_pos_x, double & delta_mass_pos_y, double & delta_mass_pos_z, double & delta_mass_moment_of_inertia_x, double & delta_mass_moment_of_inertia_y, double & delta_mass_moment_of_inertia_z ) { if (changes_.empty()) return false; mass_changes mass = changes_.front(); changes_.pop_front();// remove delta_mass = mass.mass; delta_mass_pos_x = mass.pos_x; delta_mass_pos_y = mass.pos_y; delta_mass_pos_z = mass.pos_z; delta_mass_moment_of_inertia_x = mass.moi_x; delta_mass_moment_of_inertia_y = mass.moi_y; delta_mass_moment_of_inertia_z = mass.moi_z; return true; } Edited October 31, 2012 by Alex O'kean 2 Link to comment Share on other sites More sharing options...
CptSmiley Posted October 31, 2012 Author Share Posted October 31, 2012 (edited) Thanks Alex, my basic process before was... if(inertia.x != f16inertiadata.x) { delta_mass_moment_of_inertia_x = f16inertiadata.x - inertia.x; return true; } else { return false; } where inertia.x is the one pulled from the get_mass state function and f16inertiadata.x is what I want it to be... that, I hoped, would force the inertias to match the data values I want instead of the internally calculated inertias, however that is done. Is there a way I completely overwrite the mass/inertias without sending it deltas? I'll try to format like your method above and see if I have any success. Thanks again Alex! EDIT: Oh and any tips on the gear state issue? Figured it woudln't hurt to ask!
