Three.jsで作るマルチプレイ対応の帆船航海ワールド

Build a multiplayer sailing game as a Three.js web app. The player steers a wooden pirate ship with striped sails across a large low-poly ocean with rolling dark-blue waves, foam trails behind the hull and a bright sky with chunky white floating rocks. Scatter islands, named regions and other players' ships, each with a floating name label. Use a chase camera that can also swing close to the deck, a compass in a corner, and a small HUD showing speed, region, camera mode and crew count. Change the sky and water tint by region, including a dark starry area. Add a server using WebSockets so several players see each other's ships move in real time. Keep the art simple: flat-shaded geometry, soft fog and a limited palette. Done when two browser tabs can sail the same sea, the ship rides the waves, and the HUD and compass update as you travel.
