Park another car

Goal

The hangout kit's street has a third car anyone can get into with E and drive, the same as the two it ships with. The cars are declared by where they are parked, so a new car is one more spot.

Files you will edit

• src/street.ts

Steps

1. Add a parking spot. CAR_SPOTS lists where each car stands on the floor plan, [x, z] in metres; every car is parked facing west. The street runs along X between the doors, and STREET_BOUNDS keeps a driven car inside x in -10..10 and z in -3..3, so park the new one there, clear of the others (a car is 3.8 m long).

   /** Where the cars are parked: on the street, facing west (yaw PI/2). */
   export const CAR_SPOTS: readonly (readonly [number, number])[] = [
     [-4, 0],
     [4, 0],
     [0, 2.2],
   ];

   Nothing else changes. src/game.ts spawns one Sedan per spot, and src/props.ts sizes the car lanes (pose, speed, driver) from the same list when it finds the cars in init.

2. Rebuild the guest, because Play Solo's authority runs it:

   npm run build:guest

Verify

npm test

passes as before. Then npm run dev, open http://localhost:5196, walk to the middle of the street: a third red car stands there, and next to it your HUD says E: drive. Press E and W: it drives off west.
