Digital Combat Simulator – DCS Plugin 2.0.0.0

Most of the simulations actually do not include the earth gravity. Most just move in 0-gravity space
One of the few that apply earth gravity is DCS.

Now you cannot just subtract 1 g from heave. Imagine flying a curve:

a portion of the earth’s gravity will be “pulling” on heave and the remaining portion on sway.
So the correct way to eliminate the earth gravity would be:

1. Convert the local accelerations (heave, sway, surge) to world accelerations.
2. Subtract the 1 g from heave in world coordinates.
3. Convert the world accelerations back to local accelerations

I have not implemented this in the DCS plugin.

Hello,
maybe I am complete idiot, but I spent half od day with this plugin and best results what I have is error in dcs.log
00209.696 ERROR Trigger: can't execute trigger, err:"[string "?"]:1: bad argument #1 to 'loadstring' (string expected, got function)"
Iwas trying original plugin and this plugin in thread.

Please, can someone help me?

I haven't had that error but I have been flying P3D recently so will go and check it out later today.....the 1.27 update may have broken something.

Thank you, I am awaing any news, right now I am trying to debug LUA, I think that data are not sending over socket

OK today I sniffed UPD packets and DCS is sending data, that is good.
Bad is that plugin in Simtools is not recieving UDP data even if try to send it manully.
Any chance to check, change plugin?

Ok I updated to the latest version of DCS and used my LUA script that I posted earlier and it worked fine with no errors. Use my export.lua, instead of the plugin version, and place in C:\Users\yourname\Saved Games\DCS\Scripts. Make a backup of your current export.lua first. Even though its meant to be used as Combined Helios/SimTools LUA it still works fine standalone. I have re-attached it here in case I had made changes to it last year when I last played. You may need to change some of your interface and axis settings in Simtools Game Engine. FYI mine are:

Interface 1 :Com 3
Interface 2 :Com 4

(the following lowered for smoother ride testing atm)
Speed 2045
Accel 98

Axis 1 Roll (rev) 75, Pitch 75, Surge 60, Sway 100, Heave 100

Axis 2 Roll 75, Pitch 75, Surge 60, Sway 100, Heave 100



Your mileage may vary depending on actuators and DOF etc

Apart from the above, as I am not getting any errors, I cant suggest anything else except a reinstall of DCS and start fresh....that way no corrupted LUA's anywhere.
Is it working with other games and plugins?

Thank you, but still not working
1. Other games like DIRT and Rfactor are working
2. Your Export.lua is same as is in plugin
2. When I use UDP packet sniffer I see that script is sending data, thats good, so I think that problem is in plugin DLL only

btw I a running on Windows 7 64bit Czech localisation.
In attachement you can see running DCS and dead Simtool

I solved this problem, by make plugin yourself.
Problem seems to be in decimal separator, becouse I am in CZ using comma.

I attached export.lua and dll with plugin(temeletry is working, installation isnt implemented.)

Problem is very simple, original plugin working! but only on systems where is decimal separator "."
we use "," so plugin doesnt work.

Best way how to definitly solve this issue is to rebuild plugin, that will respect local decimal separator

Does anyone know if the issues with this plugin are sorted yet or do we need a new one? I only see the original version in its history. Thanks.

Original one works OK, but you MUST have in decimal separator . (dot) in you national settings

It would be great if the DCS plugin could be made to function in the same way as IL-2 and Cliffs of Dover. These work beautifully with the servomotors in my 4 (shortly to be 5) dof pneumatic motion platform, but the Heave motion is still odd compared with the other flight sims. It is reversed and the centre position is not zero as the others are and comes out as Sway. I guess it is to do with Earth gravity being included, but it really mucks up the way the g forces feel. Sounds trivial, but I just cannot get it to feel right when flying around which is a shame as DCS is a lovely sim. And will be even more lovely when the WW2 version is released.

@value1 , Would you please post which DCS output values in the lua script are used with each dof in the DCS plugin? If some of us knew exactly what outputs we are dealing with, we may be able to sort out issues with the plugin.

Hi @hugso
Thank you for your feedback.
So I understand that heave and sway are interchanged? I can change that easily.
Heave (or sway currently) should be reduced by the earth gravity? To make this properly, it's some maths that I have to apply. Let me see…
Can you confirm that the other values are correct?

Appreciate your feedback!

Ehm… the same original plugin runs with 1.2.6 and 1.2.9. There is no issue with the functioning of the plugin (other than when you have some local country settings that screw up the ";" and "," and sway and heave mixed up and heave +1g too big [which I have explained already here] )
But please let me know, if there is something else wrong with it.

Still working fine for me too. But I am still on 1.10 software. Might take the plunge and upgrade to 1.2 but I am scared....if it aint broke dont fix it.....Damn I'm a pussy. Hey Value1 I forgot....if I upgrade do I have to redo all my games and settings in the manager and engines....that's why I'm scared....lazy might be the more appropriate word...lol

Never change a running system LOL
When 1.1 works fine for you, leave it.

Hi @value1, thanks for your reply. The Heave signal (coming through Sway) seems to be reversed. If I swap this with Axis Assignments I then have to move the arm on the servomotor shaft to get 1g in the centre of the servo's movement. The bit that really is strange is that when the aircraft is on the ground the position of the Heave servo arm is about 40 degrees different to where it is when flying straight and level. I really could not get Heave to feel right when flying, which it does in IL-2 and Cliffs of Dover. I must confess I have not tried things out since the start of this year. I am on Simtools v.0.1.2.0 Thank you for your work. If it is possible, I would love to have airspeed added as this is very helpful to me for firming up the control column stiffness amongst other things.
