Canyon's jumps, and the boxes by the road

2026-10-24, the pod-physics session.

The eight cars of the step-logged Gold race on Canyon (derived/physics/gold-canyon), seen from above. The player's car (red) was driven by the game's own AI from the start.

A second race

The race-loop session recorded a Gold race on Canyon, with damage switched on, from inside the game. Canyon has jumps: the player's car rose to 41 units and came down again. Beltane had none, so the code for a car in the air had never been checked.

Every one of the race's 18,600 car steps matches the game, word for word, the jumps included. The port also carried all eight cars through the whole race on its own, 2,325 steps and 60 contacts between cars, and matched the game at every step.

Damage was on, and the game made 274 damage calls; all match. Some came from a car hitting a wall with several points at once, a branch that had never run before.

The props

Canyon has twenty boxes stacked by the road. Props like these (cones, drums, boxes, signs) are on 25 of Gold's 33 tracks. Nobody hit one in the recorded race, so the boxes were moved inside Gold's own code, under the emulator, into the cars' path at eight points of the race, in the air and on the road. Then each step around those points ran again.

A box is a small rigid body with eight contact points. When a car hits it, the box is pushed by half the overlap and takes an impulse; the car is pushed back and takes its share, and its damage. The box then pushes any box it touches and moves on its own: gravity, the road under its points, friction, a spin that dies away, until it rests on three points or more and settles.

Every call matched: 77 hits, 77 box steps, 55 of them on the road, and 208 whole collision passes with cars, boxes and damage together. One thing could not match and does not need to. When a box finds no ground, the game copies a rest point it never set, whatever its stack held before. The game never uses that point without a face to go with it.

Next

Boxes against walls and against each other, and one falling out of the track, have not happened in any run yet. The damage record the race display shows waits for the display.
