探秘《Noita》的技术与设计

In this 2019 GDC session, Petri Purho of Nolla Games explains the technical side of Noita's physics engine, including scaling a falling-sand simulation to large continuous worlds and adding destructible rigid bodies. It also shows how the emergent physics drives the gameplay.

Why HN likes it: It is the go-to talk for anyone building falling-sand or pixel-physics simulations, and several commenters say they modeled their own engines on it.
