Adding Telemetry Data output for Motion simulators

[sci666-2023]

That would be 1000000000% immersive !!!! game with VR in a motion rig !!!

maybe this helps:
https://www.xsimulator.net/community/faq/devs-how-to-add-telemetry-output-into-a-game-unity-and-ue4-code.287/

just an example how this would look like:
https://www.youtube.com/watch?v=DQ_bFsmPpHQ&pp=ygUTbW90aW9uIHJpZyA2ZG9mIGRpeQ%3D%3D

and no, it should not be complicated, the game does NOT control the rig !!! it just provide the data for, surge, yaw, heave, exelaration, etc. in some format.

so the rig software can pull these data out of the memory and translate it to movement data...

what informations do you need a good source is the first link and there are also Devs for the tool that controls the motion rig which can help you how to implement the telemetry data output.

i made a small version that should give the telemetry for everything but gforces.
i have no way of testing it though so let me know if it works.

to install it you need olmod:

1. https://olmod.overloadmaps.com/

2. go to the olmod folder and replace its GameMod.dll with this file
   https://uploadnow.io/f/tv1GGxS , if that upload platform is sketchy i can share it over discord

If it worked you should see TELEMETRY in the top right corner of the main menu
it sends to 127.0.0.1:4123

Hi Lukas, wow sounds good.I will share this Information with my xsimulator forum friends. They have to grab the telemetry Data from the memory to make a plugin. I will let you know. Very best!

i put the informations into the xsimulator forum:
https://www.xsimulator.net/community/threads/help-plugin-for-overload-got-implementation-by-the-developers.18757/#post-248193
User Yobuddy will take care of it - i hope he has a bis spare time for this one :) . maybe you can get in touch with him directly or vice versa
Thanks you !

Hi Luponix, Yobuddy and i tested it and we followed your orders with olmod and stuff and the game shows "Telemetry" in the main menu but it seems that there is NO output because all Values stayed with value Zero. :(
For Testing Values are watched with a small Tool called "UDP Reciever" i will attach it here. please can you take a look again on the output ? Maybe you can use it to determine whats going wrong here ?
and theres an additional wish from our xsim Dev Yobuddy, can you change the delimiter to semicolon instead of Comma ? its more usable because of problems with decimal delimiters if you use commas.

ok. will check whats going on there this weekend. thx for including the program. that is going to be a huge help

[luponix]

turned out to be a simple fix. the object i attached the script to got destroyed when changing scenes.

there are a couple changes in this version:

• output is seperated with ';'
• gforces based on the acceleration work now
• it outputs some extra events

Format:
"{0};{1};{2};{3};{4};{5};{6};{7};{8};{9};{10};{11};{12};{13}"
0 = Roll (rotation.z), // angles in degrees (-180 to 180)
1 = Pitch (rotation.x), // angles in degrees (-180 to 180)
2 = Yaw (rotation.y), // angles in degrees (-180 to 180)
3 = angular velocity.z, // in (rad/sec)
4 = angular velocity.x, // in (rad/sec)
5 = angular velocity.y, // in (rad/sec)
6 = Gforce.x,
7 = G-force.y,
8 = Gforce.z
9 = EVENT: Is the player boosting ? : {0f, 1f}
10 = EVENT: Is the player firing the primary weapon ? : {0f, 1f}
11 = EVENT: Is the player firing missiles ? : {0f, 1f}
12 = EVENT: Did the player just pickup an item ? : {0f, 1f}
13 = EVENT: How much damage did the player receive since the last update (16.6666ms) ? : {0f, <...}

Hi. Wow. Thanks a lot. I will forward this to yobuddy. I will let you know what He say.

Any progress on this @sci666-2023?

[phunkaeg]

@luponix - we've created a plugin to get the telemetry working and passed on to Yaw3 via the Yaw GameEngine software.

https://github.com/phunkaeg/OverloadPlugin_GameEngine_YAWVR

I'm running into an issue at the moment where the telemetry seems to be world-based instead of player-orientation based.

For example, if I interpret the gForceX > Chair Pitch. It will pitch backwards if I accelerate in one particular direction. Lets say "East". However, if I accelerate West the chair will pitch forward. And if I accelerate North or South, the chair doesn't pitch at all.

Would it be possible to modify this on the telemetry output side?

[phunkaeg]

@luponix - I have no idea how to do coding. But I tried decompiling the GameMod.dll file and seeing if I could find how the telemetry data was being sent, to see if there was an easy way to change it to Local-space.

I didn't know how to do it, so I asked ChatGPT (don't hate me please!)
Which said that it could add some Local-space conversions to the code.

Not sure if this is total rubbish or not, but it might save a bit of time.

Heres how you convert a Vector from World to Local Space

public static Vector3 WorldtoLocal(Quaternion rotationQuaternion, Vector3 v_world)
{
    //normalize the quaternion
    var qN = Quaternion.Normalize(rotationQuaternion);

    // Convert world vector to local vector
    Quaternion l_world = Quaternion.Conjugate(qN) * new Quaternion(v_world, 0) * qN;

    //return it
    return new Vector3(l_world.X, l_world.Y, l_world.Z);
}

hello there, sorry for the laaaate reply ...i was the initiator of this :D i had some private issues and vacation and stuff so i do not have the time. as mentioned above the relation seems to be wrong implemented, world based and not "player" based ...

for example, i accelerate and then break the simulator moves back and forth ... but when i turn 90degree and accelerate and break the simulator moves left and right instead of back and forth ... you know what i mean

yobuddy from xsimulator forum tested it with same results for Simtools.

@luponix please take a look and the movement relations :)
