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]

umm isnt the API in a root/DCS World/ folder?

[SkateZilla]

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.... But maybe it's for our own benefit.

[Krebs20]

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?

if a frogfoot crashes in the middle of abandoned North East Georgia... does it make a Sound?..

 

 

That seems to be the common response "if/when you get 3rd party developer status"

[Tango]

Sorry guys but we are under NDA. I'm guessing you don't honor those?

 

SE did the work on this, and I put the skeleton code together. This is what I know about the AFM, but can't say:

 

 

I think I made my point clear enough?

No idea. I didn't even know it was left in the public release.

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.

We do, we are in the process of obtaining 3rd Party Dev License... Emails exhanged, package being prepared for ED etc.

 

Hopefully ED see's us worthy, and we are able to continue working on items with better help/assistance.

[SkateZilla]

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?

I am currently under no NDA so have no clue what I can/can't ask. The AFM API, as it is in 1.2.1 is available to everyone and I am asking questions about the features within that code, which I believe would fall under the umbrella of "modding".

 

Unless you tell me what I can and can't ask, I'll continue to try to find out how to do things.

 

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!

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.

[SkateZilla]

understandable...

[SkateZilla]

Cant Get a License without a Working Proof Of Concept,

But we cant get a 100% Working Proof of Concept with out answers...

 

 

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]

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.

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.

[SilentEagle]

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.

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.

I know a sh*** about these things, though I like to read trough it. So much talented people around here, amaze me every time.

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;
}

some issues tha i forgot to mention :

configuring initial state of rigid body parameters

 

local cockpit_path  = current_mod_path..'/Cockpit/Scripts/'
local FM = 
{
[1] = self_ID,
[2] = "FM_dll_name",
center_of_mass     = { 1.0 , 0.1 , 0.0},   -- center of mass position relative to object 3d model center for empty aircraft
moment_of_inertia  = {1000, 3000, 3000},   -- moment of inertia of empty aircraft
}

make_flyable('My Aircraft ID',
		  cockpit_path ,
		  FM ,
		  current_mod_path..'/comm.lua')

[Alex Okean]

SFM unfortunatelly don't know about inertia in most of cases

Not pretentious - just don't want to go busting any NDAs. Second, I didn't know it was supposed to be public - I did make that point quite clear where I said "no idea". I only have the dev build installed.

while we got alex, gear states... for afm.. so we arent belly sliding with gear down.

[SkateZilla]

half the Falcon demo is Landing taking off, touch and go, then the normal minimum radius turn, hi speed pass, vertical.. etc etc.

"Viper West" on Youtube, there's plenty of tach demo's in HD now.
