Learn how to implement boat physics in Unity

Hi!

Welcome to the #6135 most starred GitHub account in the world (Source) and the #126 most followed account in Sweden (Source)!

The one who's running the show is me, Erik Nordeus. I'm an imagineer (creative engineer) who's interested in the intersection between art and engineering. I design mostly Unity and Blender projects. After finishing my mandatory military service, defending King and country, I got a master's degree in Mechanical Engineering from the Royal Institute of Technology (KTH) in Stockholm, Sweden, where I also live. The rest is history...

My goal with my open source projects is that the code should by as easy as possible for you to understand, so I love to comment it! I once wrote a book about a guy called Elon Musk, and I read somewhere that authors are the best at commenting code because they know how to explain complicated topics in a simple way. Thus I hope I will fulfill my promises!

FAQ

• Are you related to the company Nordeus? No, my surname Nordeus is a family name. If you googled Nordeus before the Nordeus company was founded you could only find people with that name in Sweden, so I'm not sure how they got the name. But they follow me on Twitter! Kinda funny that both of us are into Unity.

THANK YOU...

...everyone who has used and contributed to my open source projects!

If you use the code for something cool then you can @ me on twitter.com/eriknordeus and I promise to retweet!

Quick question about drag caused by slamming

Hey Erik,
Firstly, thanks for making this, it's much appreciated.

I'm making a boating game and i have used this code to make floating more dynamic.
I'm experiencing some issues trying to get realistic water drag because the slamming causes velocity to drop quickly, even with 0 drag.

Here's a video of my issue
https://vimeo.com/774041994
First 25 seconds is using total mass = 1000 and slamming cheat = 3.
Then i turn down slamming to 1, which lets my boat glide with low drag, but this makes the boat very unstable causing rolling.

Any tips would be greatly appreciated.
I already reduced all forces by 100x, allowing me to reduce the rigidbody mass to 1.
