Working on other things,

 

what does it mean when you goto start a mission with a new module,

 

it loads ground objects, then gets to 50% on the next bar, and then re-loads the menu?

 

is it a LUA Problem or a edm issue?

 

edit: must be an EDM issue, swaping with another EDM bypasses the issue, back into 3ds Max i go......

 

edit edit, nevermind, it was because i had two Modules with the same code, lol... duh..

Alex, could you give an example of duplicating a default FC2 aircraft while calling a default cockpit that works as a sample aircraft? I've tried to remove all wunderluft references and duplicate the

How prevalent is this guide now? In relation to DCS 2.7 now that it is out? Is there a newer guide available?

is the formatting for the lights in the wunderluft profile correct?

 

I can seem to get them to work on my model or the wunderluft, but if I throw my model in as a sub to say the F-18C my lights work fine....

You'll have to change them accordingly (names and args) to the clickabledata.lua and your 3d shape in 3dsmax.

ok, I must be missing a line somewhere.

 

made 4 modules with the wunderluft template.

 

but i can only use one aircraft at a time, and I have to move the other 3 out of my Aircraft folder to use one, or DCS Crashes...

 

So... Is there an Aircraft unique ID Number??

How to create debug window for dll tests?

I was looking at c++ forums, but basicaly there is working example for console and form apps, not for dll.

 

I added

#include <windows.h>
#include <iostream>
using namespace std;

 

and

 

cout << "thrust = " << throttle * 5000;
cin.get();

in void ed_fm_simulate(double dt) function, but no any debug windows or forms appear.

Thx Smiley, good to know thats not my prob.

Did you tried to use some socket connection, or writefile function for debug?

I'm stuck on trying to work on the cockpit and hoping you guys can help.

 

I have a device set up, I have the code for it installed, I followed the procedures as shown in this thread to do a gear up/down switch.

 

But when I get in the cockpit, I don't see my cursor to actually click on the switch. Since it's initially in mouse view mode I hit LALT-C to change it but still no mouse cursor. Is there a setting in a aircraft LUA that makes it non-clickable that I missed?

Shouldn't be. There are some bugs in the latest version of World that involve a disappearing mouse. First step is to try moving your mouse around a lot and clicking middle mouse button (or all the mouse buttons!) The missing cursor is NOT an issue with your model or code. If you can get the cursor to show up, I can fix the rest of your problems!

Tried all the mouse button with no luck. If I load up the KA-50 (which I have a installed on my modding laptop) I can click everything fine. If I have then load up the wunderluft that's set up - nothing. Will keep messing with it.

 

 

UPDATE: So I noticed when I first get in the pit I do see the cursor. But if I got from mouse mode and back, I lose it and no clicking will get it back. So I've been setting it on forward view and using zoom to get to the switches I need. So far tests have been good.

 

In reading this thread I noticed that there are standards that DCS uses. Like iPlaneGearDown is 431. Is there a list of all the standards somehwere? I have the gear ones and flap ones thanks to this thread but would love to learn all the other things that are already built in.

Thanks for the plugin tutorial,

 

managed to make a little theme plugin for our squadron :)

I do not know if any updates just caused this issue but for some reason I have now lost all external animations with my Wunderluft aircraft.

If I kill the "test" line item out of the devices .lua the cockpit now disappears and the animations work.

I add that line item in and then the cockpit returns and the animations do not work.

The only external animation that still works is the canopy draw.

They all do still work in the modelveiwer however which is very strange.

I also just reloaded a fresh Wunderluft with no editing at all and the same issue now exists.

I know when using a fresh copy this issue did not exist before.

Any ideas?

I am updated to the 2.2.2 and it had worked in the past few weeks ago.

Not very happy here....

If someone interested, here is my way to create debug console window for your external flight model.

Just look at Code Block, russian is just explanation.

Some issues:

-Can be in the future add Brake and Tire temperature? (to degraded friction, fire and tire explosion)

-Can simulate runway condition with affect to the wheel friction over runway?

 

Brake temperatures condition is completely on your side of modeling , i.e. returned brake moment from your model should changes with temperature. , runway conditions , we have them in some way , so it our side

So I guess I can post this here now:

 

 

Can anyone provide any description or units for any of these items in the suspension? Many of them are understandable, but without seeing the equations behind the suspension code, understanding these inputs is almost impossible.

 

{

mass = 200,

pos = {0,0,1},

moment_of_inertia = {1000,1000,1000},

 

 

damage_element = 83,

damage_omega = 30.0,

state_angle_0 = 6.131341662,

state_angle_1 = -2.995164152,

mount_pivot_x = -0.274,

mount_pivot_y = -0.118,

mount_post_radius = 0.657,

mount_length = 0.604555117,

mount_angle_1 = -3.138548523,

post_length = 1.748,

wheel_axle_offset = 0.05,

self_attitude = false,

yaw_limit = math.rad(89.0),

damper_coeff = 30.0,

 

 

amortizer_min_length = 0.0,

amortizer_max_length = 0.397,

amortizer_basic_length = 0.397,

amortizer_spring_force_factor = 1.6e+13,

amortizer_spring_force_factor_rate = 20.0,

amortizer_static_force = 80000.0,

amortizer_reduce_length = 0.377,

amortizer_direct_damper_force_factor = 45000.0,

amortizer_back_damper_force_factor = 15000.0,

 

 

wheel_radius = 0.308,

wheel_static_friction_factor = 0.65 ,

wheel_side_friction_factor = 0.65 ,

wheel_roll_friction_factor = 0.025,

wheel_glide_friction_factor = 0.28 ,

wheel_damage_force_factor = 250.0,

wheel_damage_speed = 150.0,

 

 

arg_post = 5,

arg_amortizer = 6,

arg_wheel_rotation = 77,

arg_wheel_yaw = -1,

collision_shell_name = "WHEEL_R",

},

 

 

Here is what I understand so far:

 

{

mass = 200, -- (kg) Is this the mass of the wheel and strut?

pos = {0,0,1}, -- (m) Is this the location where the tire impacts the runway or the location of the strut mount point?

moment_of_inertia = {1000,1000,1000}, -- (kg-m^2) Is this the moment of inertia of the strut and wheel in the down position? Not sure what the coordinate system here is.
