Data-driven parks: one heightAt(x,z) evaluated from element JSON drives the editor viewport, collision, test ride, and exported game levels. Ships with Paddo ported from bookquoy, a MODELBEAST panel (gen images, cut bg, image->3D, place farm GLBs as props), image decals + reference underlay tracing, a park design linter (docs/DESIGN_PRINCIPLES.md), THPS-style instant test ride, and a level.js codegen that drops straight into bookquoy.

# What makes a great skatepark
|
||
|
||
The design brief behind PARK CHECK (`js/parkcheck.js`). World units are metres;
|
||
bookquoy scale maps 1:1 (a 1.8 radius quarter = a 6ft quarter).
|
||
|
||
## Flow & line architecture
|
||
- **Collision-free traffic paths** — no intersecting lines; nothing drops in across
|
||
another feature's run.
|
||
- **Adequate flatland & run-outs** — 10–15ft (3–4.5m) of clear flat for setup and landing
|
||
recovery. Tight squeezes kill speed and create bottleneck bail zones.
|
||
- **Pumping geometry** — transition radii that feel natural: 6–8ft (1.8–2.4m) for
|
||
street-flow sections, 9–11ft+ (2.7–3.4m) for deep bowls.
|
||
|
||
## Obstacle variety & progression
|
||
- **Skill tiering** — 8–10in (0.2–0.25m) micro-ledges and mellow banks alongside the
|
||
14–18in (0.35–0.45m) standard ledges, handrails and hubbas, so beginners progress
|
||
without occupying main lines.
|
||
- **Terrain balance** — street (stairs, manual pads, flatbars, euro-gaps) paired with
|
||
transition (spines, hips, speed bumps, open bowls).
|
||
- **Coping mechanics** — consistent reveal (~3/8in proud above and in front of the lip)
|
||
for predictable grinds; pool coping and tile in advanced bowls. *(Game mapping: rails
|
||
hug the deck height — PARK CHECK flags buried or floating steel.)*
|
||
|
||
## Surface & build quality
|
||
- Smooth high-PSI steel-trowelled concrete; prefab metal/wood deteriorates and seams at
|
||
the transition base. *(Game mapping: one continuous heightfield — no seams by
|
||
construction.)*
|
||
- Expansion joints routed away from landings and slide paths.
|
||
|
||
## Drainage & sightlines
|
||
- Drains and micro-slopes strictly outside trick lines; no puddle pockets.
|
||
- Open sightlines across the footprint to spot traffic and clear landings.
|
||
|
||
## Amenities & community
|
||
- Lighting for evenings, shaded perimeter seating clear of run-ups, water, bins, transit
|
||
access. *(Game mapping: props/set dressing live outside the bounds slab.)*
