用 Claude、Tripo 和 Godot 做 GTA 风格城市

Inspect the current Godot project and build a runnable GTA-style coastal city prototype. Use only native Godot nodes and primitive geometry such as BoxMesh, PlaneMesh, and CylinderMesh, together with road meshes, collision bodies, materials, lights, cameras, and GDScript. Create walkable roads, buildings, elevated roads, tunnels, a waterfront and water surface, placeholder palm trees and street lamps, and simple placeholder vehicles. First complete an explorable city blockout with basic collision, a day/night toggle, and first-person/third-person camera switching. Run the project and verify that the overall scene and interactions match the reference image. Create all nodes, scripts, and scenes inside the Godot project. Save the scene as res://scenes/neon_coast.tscn and keep the structure ready for Tripo-generated GLB assets to replace nodes or resources at matching names and paths. Do not rebuild unrelated systems and do not generate or import final 3D models at this stage.

Use Tripo CLI to prepare the assets for this Godot project. Generate hero_male from the provided character reference image, then complete its materials, rig, and these seven animations: idle, walk, run, sprint, jump_start, jump, and jump_land. Generate car_sedan, car_sports, car_convertible, hotel_facade, motel_sign, palm_tree, and street_lamp as separate assets. Save the task status, final model, and failure information for every item. Confirm that each final GLB exists, then organize the assets under matching directories in res://assets/tripo/. If a task fails, retry only that task instead of repeating the entire batch.

Complete the city in the neon_coast scene without connecting the character yet. Use CityStreetStylizedPack as the base environment. Add the waterfront and water surface, place palm_tree, street_lamp, hotel_facade, and motel_sign, and add signs for HOTEL DIXON, OCEAN DRIVE, JUICE CAFE, Vice Beach, BAR, and BURGER. Use car_sedan, car_sports, and car_convertible to create two-way looping traffic. Correct the vehicle scale, orientation, lane placement, collision, and headlights. Refine the existing T-controlled day/night environments: preserve road and building detail during the day, and emphasize neon, fog, headlights, and road reflections at night. Run the scene and check each part before connecting the character.

The city, roads, vehicles, and day/night environments are complete. Now connect res://assets/tripo/hero_male to the project. Add the character as a CharacterBody3D, calibrate the feet and capsule collision body, and connect the idle, walk, run, sprint, jump_start, jump, and jump_land animations. Use a third-person SpringArm3D that follows the character, and let V switch between first-person and third-person views. When the character is near a vehicle, pressing F should enter vehicle-driving mode. Add a circular minimap, a time display, health and armor bars, money, and a wanted-level HUD. Preserve the completed city, traffic, and day/night logic; do not rebuild the scene.
