DCS A10 Support? solved with post #24909

[sirnoname]

You mean I should use double instead of floats?

[laurivs]

Oh, and I don't understand is how can we do the multiplication in plugin afterwards? Adding zeroes to the end of our result doesn't increase accuracy. The "multiplication" in export string is more than just adding zeroes to the end.

I think we need to have the multipliers in the export.lua
Why?

Example1 ( no multiplication in export.lua)
Yaw data reads 5.35 *57,3 = 306,555
Yaw data reads 5.36 *57,3 = 307,128
Yaw data reads 5.37 *57,3 = 307,701

Example2 ( multiplication done in export.lua (... pitch, bank, yaw*100, accel.x, angle, .....))
Yaw data reads 534.70 * 57,3 = 30638,310
Yaw data reads 534.71 * 57,3 = 30638,883
Yaw data reads 534.72 * 57,3 = 30639,456
Yaw data reads 534.73
Yaw data reads 534.74
Yaw data reads 534.75
....
...many possible values are now available until we even get to 535.00. Compare this to the example1 and you'll notice the difference.

As to float or double? I don't know anything about that in terms of computer science, I'm no programmer!
I just know what kind of accuracy we need and a simple cave man's way to get it. What do you think?

Working with floats means using dot number with a easy precision. For this case about ten numbers behind the dor it would be no calculation error. Doubles do get more precision.
The plugin work with floats but I will double check your ideas.

Great,

Now we're getting good progress! By the way, you don't need the yaw*100 but then you have to export more decimals, like this way:

if c then
socket.try(c:send(string.format("%.3f %.2f %.2f %.2f %.2f %.4f %.2f %.0f %.2f %.2f %.2f %.2f %.2f %.2f %.2f %.2f %.2f \n", t, altRad, altBar, pitch, bank, yaw, accel.x, angle, accel.y, accel.z, accel.x, accel.y-1, accel.z, user4, user5, user6, 7)))
end

Notice %.4f for yaw. This completely gets rid of the .57 problem! Now we have .01 increments and good resolution. This works perfectly, and we still have 360 degrees. Problem solved. Let's move on!

If we want more accuracy, we can do it by allowing more decimals to be shown in the plugin or by multiplying the value in export.lua.

Would you like to try the bank speed value now? I believe we're ready for it. Are there any more problems before that? I don't think so.

I just tested even with 7 decimals. It works and is very accurate! Check the following image to see for yourself.

[sirnoname]

I have done a new algorithm for the speed and changed to DCS plugin.
So please copy the plugin to the X-Sim directory and check if the DCS plugin is correctly loaded if you select the plugin in the extractor.
Then check the values. They must stop at pause and the spike must be gone. We must change the LUA script to the order that all values do fit like in the original lua. We must finish all values and perhaps add some user values with real used values.
Then we must change the auto installer script that all is installed correctly, I do only have DCS World with steam and do not know where the executables are normally and how is the name of them.

[laurivs]

Omg, now installing and testing!

Ok, so I can manually open the DCSImport.exe and it looks great! But, I was unable to have the extractor find the plugin. In other words, I can't select DCS plugin from the list of plugins.

I copied DCSImport.exe & DCSPlugin.dll here:
C:\Program Files (x86)\X-Sim\Plugin\

Extractor -> Motion Driver-> Telemetry plugin -> ? DCS can't be found here. Do I need to do something else for the program to find DCS plugin? Shouldn't it find it automatically during startup of extractor?

I managed to cheat by naming the DCS plugin as the old lockon plug and it received data, no more bank speed spike problem! Missing user1,2,3 lateral values and a lot of other values too. And of course all the proper names are still the old ones in extractor and converter. So the names of the values don't match.But I'm sure once we get the DCS plugin with DCS specific dll loaded properly in the extractor, these problems will go away.

But anyway, excellent work Sirnoname, thank you so much! We're almost there

And this is how the non-steam DCS folder structures look:
