The tree is rebuilt every frame. For scenes of this scale, quadtree construction is fast enough to rebuild from scratch each frame, though larger simulations may benefit from incremental updates. Each particle queries its neighborhood for potential collisions, typically checking only 5 to 15 candidates instead of all 40. Red highlights indicate colliding pairs.
The C64 version of Lights-Out is one of the first ones I wrote, and as a result it was a bit more ad-hoc about its display code. When moves are made, it goes and updates the cells that changed immediately; it wasn’t until I started making versions for game consoles that I made a sharper distinction between “model” and “view”, rendering the full board anew each frame from a central, more abstract representation of the puzzle state.
