January 2024 update

Hi everyone,

To start the year off, I decided to keep working on motorcycle controls. Confident with how it feels, I have made them public on the Touristenfahrten world. They have:

- Ph...

Steering wheel and force feedback support

Hi everyone!

The first working prototype has been made.
I wrote a separate software that reads data from VRC to send the FFB signals to the wheel.
There is currently a bit too much lat...

Early December Update

Hi everyone,

Happy holidays if I don't post again this month!

The new rim models for select cars have been uploaded to the Touristenfahrten world.
My plan for the rest of December ...

Touristenfahrten November Update

Hi everyone,

I started picking up 3D modelling as mentioned in the October update. I have started by modelling the rims for the cars I want to model.

This was done by getting image re...

Touristenfahrten October update

Hi Everyone,

In October and early November, I worked on fixing issues related to the new Unity 2022 version and the custom car netcode.

Since my last post, I mentioned, "I will be doing...

Updates to Touristenfahrten

Hi everyone,

In September, I have done the following (don't worry, some of these will have their own posts with pictures or videos!):

• Removed the respawn button in favour of a ne...

Rumble strip and suspension sounds

Hi everyone,

The Touristenfahrten world now has the rumble strip and new suspension sounds. Previously, there were only suspension sounds that only played when the suspension goes past its li...

Custom interaction framework

Hi everyone,

I have created the base of an interaction framework for use with my systems.

How does it work?

I will call objects you can grab "interactables". Thes...

Tire temperature and wear

Hi all,

I have developed a one dimension tire condition system that encompasses temperature and wear which influences the already existing tire pressure system.

After much testing, it w...

Progress and outcome of FPS lag hunting

Hi everyone!

Let's start with the FPS hunting. So Unity UI was found to be a big factor in FPS, especially while driving. I will be disabling these out-of-car UI such as minimaps/spectator s...

Secondary culprit of poor VR FPS

Hello,

Other than the tire simulation being very expensive to do in Udon, I did a brief process of elimination on the Touristenfahrten world to see when VR FPS went back up while driving.

Touristenfahrten has poor VR FPS

Hello,

I have noticed that this world has gotten worse VR performance over time. This weekend, I will be working on alleviating some of the performance costs with the goal of increasing FPS ...

Motorcycle controls (arcade)

Before I post the car physics and game progress, this video shows the arcade steering for the motorcycle. It works, however, I am not satisfied after having tried a MotoGP physics simulator.

Motorcycle progress

I have attempted a few methods of controlling a bike so far and I want to continue persuing a physics-based method. This method is where it doesn't use any artificial forces to keep the bike uprigh...

Physics v4 progress

Hi Everyone,

I have been working on this newer version of the code for the past few months. This is not backwards compatible with my current worlds as it was rewritten from scratch with knowl...

Session lap time display

Hi everyone,

For the past week, I have added a lap time display to the Touristenfahrten world. This will only show players in the instance and you can filter the list by car.

Power source and storage for Udon game systems

Hi everyone,

I have come up with a way to power and balance vehicles that don't use combustion engines such as the hover tank.

What is it?

A reactor po...

Transport Game (name pending) Progress

Hi everyone!

A simplified version (more FPS) of vehicle physics is on the way for this game. Featuring wheels that take on curbs correctly.

For the purpose of testing the logic of the ...

Game Time

Hello,

Thank you for your support. At this stage, I think I have a decent grasp on vehicle/tire physics. Next is to make more interactive experiences by creating game worlds. Two projects ar...

Turbo sound update

Hello!

I have updated the turbo sound to conform to the forced induction system upgrades. Going forward, "forced induction" will refer to a turbo and supercharger.

For forced induction,...

Hand Based Steering Prototype

Hi everyone!

Before we start the new year, I have come up with a prototype that lets you steer with your hands in VR.

What's in the prototype?

• Lets you ste...

December Update & Supercharger Simulation

Hi everyone,

I wish you all a safe and enjoyable festive season, this may be the last update until January.

To keep up with the goals I have set since September, I have made a new colum...

Improved Turbo Simulation

Hi everyone,

I have improved the turbo simulation and it will be up on the Touristenfahrten map.
The calculations have been reworked to have the following:

• Exhaust manifold pre...

VRChat New Years 2023 Video Submission

Hi all,

Here is the video submission!

Many thanks.

VRChat New Years 2023 Video Concept

Hello there,

As said in my previous post I was passionate about submitting a video. There will be a submission, and it will promote VRChat Udon creation by showing some car footage - a very s...

Custom editor preview for v4

OK, so the previous post didn't want to embed the image and I have made this post just for that.

Cheers

Projected development roadmap

Hi there,

Small update on the development roadmap. Car physics is currently the number one focus for my Udon work. Unfortunately this has slowed down due to my real work and life. Much of the...

Cars roadmap

I have previously said that the next post will be an overall roadmap of development in Udon, however, the subject of car development was too big to be combined with my other Udon work.

Tire Physics Roadmap

Hi everyone,

I have come up with a roadmap that outlines the development goals and usages of tire physics that are used in my systems.

The current tire physics model is to be ground tru...

High speed test track

There is now a high speed test track which is a fan recreation of the Special Stage Route X track.
