Streetline Run

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a browser-based 3D third-person action game titled “Streetline Run.” Use Three.js-style rendering with a dark navy night-city presentation: full-screen canvas, dark blue background and fog, soft shadows, cool blue ambient fill plus warm directional sunlight and a subtle blue city accent. Build a simple low-poly city arena on a large dark ground plane. Add a wide north-south road and a wide east-west crossing road as slightly raised dark asphalt strips. Place eight rectangular block buildings around the roads as obstacles, in alternating muted slate-blue and dark blue-gray materials, with varied dimensions and heights.

The player is a bright cyan-blue stylized humanoid made from a capsule-like body and sphere head, carrying a short dark metallic box-shaped gun in the right/front side. Start the player at approximately (0, 1.1, 12). Use a third-person camera following the player from behind at about 7.5 units away, with mouse-directed view. Support WASD or arrow keys for movement and Shift for running, plus jumping/gravity if provided by the third-person controller. The player can aim with the camera and shoot with left mouse click. Each shot has a short fire cooldown (about 180 ms), creates a very brief thin glowing cyan laser line from the weapon toward the camera’s forward direction, and raycasts up to about 55 units. Red enemies are simple floating/standing rectangular cuboids, each with one health point; spawn five at roughly (-16,1,-10), (18,1,-12), (-20,1,17), (22,1,20), and (0,1,-26). They continuously move toward the current player target on the horizontal plane, stopping within about 2.2 units. Hitting one shrinks it briefly and removes it when health reaches zero, increasing the score.

Include one blue boxy car near the starting area, around (12, .75, 11). Model it from a large blue rectangular body, a smaller dark blue window/cabin block on top, and four dark metallic cylindrical wheels. Put a translucent yellow circular interaction ring on the ground around it. When the player is within about 5.4 units and presses E, enter the car: hide the humanoid, attach/control the player position to the car, and switch to driving mode. While driving, W/S or Up/Down move forward/backward, A/D or Left/Right steer, with vehicle speed around 13 and turning around 1.7; use a simple third-person follow camera positioned above and behind the car so the car remains visible. Press E again to exit, placing the player beside the car. Enemies should chase the car while occupied and the player while on foot. There is no collision/damage/lives system in the shown mechanics; the only objective feedback is eliminating enemies and increasing score.

Overlay a non-interactive HUD in Indonesian over the canvas. In the upper-left, show a translucent dark rounded panel with a cyan uppercase title “STREETLINE RUN,” then the controls text: “WASD bergerak • Shift berlari • Mouse mengarahkan pandangan • Klik kiri menembak • E masuk/keluar mobil”. Below it show status text initially “Mode: berjalan”, then dynamically show “Mode: mengemudi mobil” or “Mode: berjalan,” remaining enemy count, and score. Put a white centered crosshair made of thin vertical and horizontal lines with a subtle cyan glow. In the lower-right, show a translucent dark rounded hint panel: on foot, “Dekati mobil kotak biru, lalu tekan E.”; in the car, “W/S maju-mundur • A/D berbelok • Tekan E untuk keluar”. Keep the visual style minimalist, low-poly, atmospheric, and clean, with muted city geometry contrasted by cyan player/laser, red enemies, and bright blue car.
