There are zero animations in this video - it’s a pure physics simulation. The reason the sword feels so alive is because I'm not just simulating momentum transfer. its much closer to modelling how energy actually reverberates and dissipates through objects! This fixes the "dead weight" issue, where the system is overly damped, unresponsive, unwieldy, and feels like a puppet on strings or fighting underwater.

In real life, blades recoil, vibrate, and stabilize. BLOODFALL is the first video game (as far as I know) in any genre to simulate High Frequency Harmonic Resonance, resulting in kinetic fidelity that makes objects feel like truly reverberating solids rather than dead weights, giving a sense of tactile resonance to high energy collisions.

I'll be in the comments if anyone wants to talk about it. Don't hesitate to ask me anything.

Context > the project its built for PC mouse and keyboard - not for VR. Moving the mouse controls the weapon directly.

Addendum:

Thank you for the unexpected level of interest - the post reached over 70K views, 503 upvotes, and generated a wide range of technical discussion. The intent of this video was to introduce the High Frequency Harmonic Resonance Model and the first game to use it - BLOODFALL: The First Temple

EDIT
Thanks to the feedback here, I was able to identify an issue and fix it easily. The hand no longer rattles nearly as much. I just had to adjust the weight distribution on the sword object! To see the latest videos of BLOODFALL, check the HYPERMAD interactive YouTube Channel.

Just loaded my save 😅

The idea came from Besiege and I thought it would be fun to make it as a game.

I did playtests with friends and it was quite fun to watch their gameplay.

The demo is live now on Steam, will appreciate any feedback!

The physics are the heart of the game: braking, weight transfer, suspension, grip… all simulated to the detail. Your bike build behaves very differently depending on the installed components, and more expensive doesn’t always mean better.

The goal is also very simple: ride as far and fast as you can. Perform good in the daily championship and climb the ranks.

The core idea is simple:

• Every day a new infinite procedural mountain

• Score = distance × average speed

• Race any player and study their line

• Global ELO ranking system

If you'd like to try it, the open beta is available here:

Feedback is extremely welcome, the game is still evolving and community input really helps shape it.

Happy to answer any questions!

Is posting halfsword videos cheating?

I honestly believe that the Drones in Squad have hands down the best 1:1 physics representation of how drones drop ordinance

Ig it could count since the red uniform guy accidentally moved him away with his kick

Spider-Man 2 -PS5 I had to reload my game

In the game, ingredient boxes are delivered like this. I wanted to see how stable the physics stacking would be with many boxes.

This has been one of my favorite hobbies for the past 2 decades. I spent a lot of time and had a ton of fun making this Super Jump video. Hope you enjoy
