Fellow developers! I've been hard at work upgrading my demo to the latest version of Unity and would like to share a video showing the building destruction in progress.
https://youtu.be/cucPpZU62mw?si=QNFzQJkIunjrzYX1

Bent on Destruction is a projectile launching game with realistic structures made possible by Unity's Data-Oriented Technology Stack (DOTS). Feel free to message me with any thoughts or suggestions as I plan to continue developing new levels and features. There's a demo on Steam and itch.io if you're interested in playing.

Thank you

Unity - building destruction physics demo

In this video, I showcase using the Unity game engine to create destructible building models imported from Revit. The basic flexible building model is squashed with a large mass and then blasted with projectiles to highlight the destruction mechanics. My goal is to explore and push the boundaries of real-time building destruction in Unity, so if...

The biggest hurdle in this progress update is the floors/walls deformable mesh and fracturing at runtime. ECS does not natively support fracturing so in the past I used an invisible entity which was not deformable, just a cube mesh collider attached at corner points, and the deformable mesh game object (Defkit) followed the entity by convert and inject game object. That is no longer supported so perhaps can use a Companion Object or skinned mesh renderer.

ideally the floors would be connected at the four corners and then deform to keep the corners connected to the nodes, until impulse in joint is too large, then the joint breaks and triggers fracture of the floor object (Dinofracture).

New video shows the background art and 3 buildings out of the planned 32:

Proceeding to fix entities scripts updated from 2020 to 2022 and looking forward to a playable build!

Unity physics building collapse simulation (Bent on Destruction)

Here's a sneak peek of three new levels crafted in Autodesk Revit and converted to Unity, demonstrating the structures designed to bend and break spectacularly! Working on upcoming improvements to building destruction PC demo to add more background environments, structures and features including sandbox mode for experimentation, and a battle mod...

Bent on Destruction will release for PC on Steam with SteamVR support on October 16, 2025. Implemented deformable mesh for floors with an array of squares connected by spring joints, and the fracturing is handled inside ECS (no burst) to create the explosion effect. In the intro level the player knocks the treasure chest off the structure, and as soon as it collides with ground triggers the fracture explosion. Each following level has a meanie that's perched in the structure and collides only with floors and player bullet.

Bent on Destruction - objective fracture test

This is the intro level where player will be tasked with knocking a treasure chest off of the structure to claim one of the magic items inside. Introduces the fracture logic.

Bent on Destruction - floor physics and meanies test

Latest gameplay testing places the meanies in the building. Adding high mass floor produces a pancake effect as the upper floor breaks and lands on the lower floor. The meanie is not amused!
