Digital Combat Simulator – DCS Plugin 2.0.0.0

Hello. Some time ago I had the same problem but the comunity of the forum helped me to solve! Thank you all!!!

Hey guys,, I'd like to share an issue I've been facing during the last days, just in case somebody else comes across it.

I started using the official Simtools DCS plugin for my DOFReality (3DOF) and initially I felt I was in a mechanical bull rather than in a flight sim :-( . SimTools was receiving data and it was configured properly (at least in the same way other games are and properly work). However, I realised (using SimTools Tunning Center) that the values (PItch, Roll, Yaw,etc.) were extremely high, I mean, i.e. `Max Pitch` caught something like 165343398, Yaw = 179665332 or -.650435 rather than expected range values around -180 - 180 or -90 to 90.

I tried to fix it in export.lua script by debugging and checking the values export.lua script was sending with no luck, I ended up by setting the pitch and roll angles to 180 -just to make sure my DOFReality was working, communicating and the axis were properly configured- by hardcoding values in the lua script: i.e. roll= 3.1415 but it only worked when I divided that hardcoded values by 10000 (and not in all axis) when I set back those variable from DCS API in lua -even by dividing it by 10000- it didn't work so I left the export.lua as it comes by default.

After spending several hours by looking at export.lua script I started looking at other *plugins.dll code samples in order to understand what this plugins exactly do -and how it calculate motions values- and I realised that some plugins do not take into account culture specific checks when performing motions calculations (pitch, roll, yaw, sway surge heave) regarding to decimal separators and, in my case, although all my software is in English, my regional settings are set to Spain, that's it, we use comma instead of point for decimal separators. After setting regional settings to English and re-starting SimTools everything got fixed and working. It also explain high values I was viewing in the tunning center; somehow `3.14 * 180` was calculated like `314 * 180`.

Thus, if somebody else come across with this weird high values issue which could be detected on Tunning Center, make sure your regional settings for number decimal separator use `point` not `comma`.

If somebody else has the code of the DCS plugin it could be also awesome to a add culture specific check on such operations.

Salud!

hey @yobuddy

Ok, I switched my regional settings back to Spain (that's it: my decimal separator is again a comma) and I modified the export.lua so that it checks format integrity in order to detect points as decimal separators. In such case they are replaced by commas. The snippet is:

Code:

    --gets DCS values
    local altRad = LoGetAltitudeAboveGroundLevel()
    local pitch, roll, yaw = LoGetADIPitchBankYaw()
    local accel = LoGetAccelerationUnits()

    -- values formatting to bundle   
    local bundle = string.format("%.4f; %.4f; %.4f; %.4f; %.4f; %.4f;\n", pitch, roll, yaw, accel.x, accel.y, accel.z)
   
   --does my system use commas for decimal separator? then uncomment next line
   bundle = bundle:gsub("%.", ",")

    my_send = socket.protect(function()
        if c then
            socket.try(c:send(bundle))
            end
    end)
    my_send()

And this fixes the issue. The 2 copies of the script as you pointed out above should work indeed as long as the user never changes his regional settings. A comment in the script will also be appreciated (IMHO).

Let me know if I can help you out here, thanks for replying.

Let me share a couple of screenshots about the issue for the records:

This is a screenshot of Tunning center when my system uses commas for decimal separator:


This one is when I apply the snippet shared above.

I see that the roll/pitch inversion still hasn't been sorted. I also get a violent YAW when passing through 000 degrees while turning, I'm assuming this is related?

Also, when starting in an aircraft that is not running on the tarmac, the whole rig shudders violently until I start the engines, or when the toe brakes are pressed at any time while on the ground. Any solutions for any of this yet?

I've sorted it out and now it's working fine using current plugin in DCS 1.5 (A10C and F15), could you share some screenshot like Tunning Center values or axis configuration? it could give us further details in order to help you out to sort it.

Does this help?

Tuning center

Hello,

Anyone tried the plugin with the new 2.5.0 beta?
https://www.digitalcombatsimulator.com/en/downloads/world/beta/

thx

just wondering

this myself, kind of hoping we dont have to wait

PS DCS 2.5 is a really good update

this is been ongoing for ages ! if done properly the effect is reversed when the side movement ( of the chair rocker/any ) reaches close to its limit

I dont use roll at all due to this, just sway to help make up for it

I've been flying with 2.5, same issues as 2.2/1.5. Works ok.

So this ridiculous teeth rattling shuddering when sitting on the ramp or whatever until the engine starts is just how it is?

I don’t get that Moe
Check your hardware / settings

I'm not sure what to check. I'm completely clueless with this stuff.

Here's a video of how bad it is. This is when I first enter the game if the aircraft is sitting on the tarmac not running. It behaves like this until I get the engine started.

Have you tried changing the heave value in the tuning centre from 1 and -1 to say 10 and -10. It probably won't make a difference based on how you explain the issue but worth a try.

Here's the view in tuning center, while sitting on the ramp cold. Noorbeast thank you for the links, I'm looking through that stuff right now.

The 1's for surge, sway and heave are too small. Try 10 instead…
