Warning, might ask for firewall permission… I’m not actually sure if it will or not. But it might! Needs to use port ~50000 something something in order to access your device.

Hey all, I created a bridge between this game and my Funsr Pro on a whim. It was a massive pain in the ass which I will go into below:

Pain in the ass / how the mod works

I originally started modding the game because I saw it had lovense support and thought to myself “well, it should be easy to hook in and grab that data and send it along to my device.” WRONG.

First I tried to build a lovense emulator, and I did so successfully. My first version was a Lovense Solace “server” on port 20100 that managed to grab all the driving data and send it to my device. The problem, of course, that I didn’t know at the time was that lovense devices do not run off of positional data. Instead they oscillate at a set speed. Well, I want my device to match the action on the screen, I don’t want it to oscillate either slowly or quickly depending on the depth of the blowjob.

So, naturally, I de-compiled a huge chunk of the game using ILSpy (a great program for modders, check it out) and figured out that the developer seems to have planned to intergrate stroker device support at some point. There were all kinds of pointers and data-points that were totally unused by the program – including the positional data I needed in order to drive a t-code device. So I then tried to make the device run on that.

Problem? The data points were totally unused, so there was no way for me to scrape the data from the game without modifying/recompiling the entire game; and I’m an NOT doing that. So what does that leave us with?

BepInEx and tracking animators in the scenes through unity then sending that animator data along to a bridge that translates the positional data to something the T-code device can use. That’s what this program does, in a nutshell. In case you’re curious, the particular animator is called “Hump” and has a LastDistanceIn pointer that tells us how far into the throat we are. We translate that with math to a 0 to 100 range then bing bang boom we’ve got a mod.

How to use

  1. Take every file in the mod folder and drag it directly into the main game directory (where the .exe is located.)
  2. Run the game 1 time with the mod installed and then close the game.
  3. Go into the config file in the BepInExFolder (it’s mislabeled local.lovensesync ; if you care why read the pain in the ass section.) Things to change include:

    Min is the lowest range of motion; exactly the same as you’d set for funscripts. Same with Max. You should change Invert to false if you find that the motion is upside down OR press F3 during gameplay to flip it.
  4. Run both TCodeBridge.exe AND the game. The bridge will attempt to connect to your device on the COM channel of your device automatically. If this feature doesn’t work, please post below and instead of a compiled .exe I will include an easy to edit python script that you can compile yourself to get it to work. That’s the only solution I have right now without a massive amount of effort. This mod only works for USB Serial Devices for this reason (no handy devices, sorry, I don’t own one.)
  5. Profit?

Why is it on your payhip? Is this mod free?
This mod is 100% free. I put it on payhip because I can’t promise that I’ll re-up on places like go-file or pixeldrain in the future. Payhip won’t automatically take it down in 2 months. That’s the primary reason I am using it. Also it gives you an opprotunity to donate to me if you like what I do, sort of like itch.io.

Get the mod for free on payhip.

NOTE: I will bugfix this a little bit if it is immediately obvious that it doesn’t work on PC’s that aren’t mine. Beyond that, you’re on your own! :)

Will u add support for the Handy too? :folded_hands:

I don’t have a handy so I can’t test it in order to implement, unfortunately. If someone is interested in trying to mod it themselves let me know and I can send over what I made in a more editable format.

Edit: maybe I can look into it, idk. We will see.

You’re really outstanding. You’re not just creating finished works, but also pioneering new application fields for device linkage.
