# Kart on Trolley Stand (Go Kart Track and Pit Lane)

A hire kart sitting on its trolley, wheels clear of the floor, the way a paddock stores and moves one. Trolley castors and kart wheels are all pivoted nodes, so the roll clip turns every wheel on the assembly at once.

## About

A hire kart sitting on its trolley, wheels clear of the floor, the way a paddock stores and moves one. Trolley castors and kart wheels are all pivoted nodes, so the roll clip turns every wheel on the assembly at once. Overall 1.270 x 1.240 x 2.080 m (X x Y x Z), metre units, +Y up, +Z forward, resting on y=0. Named nodes on their own pivots: the four kart wheels and the four trolley castors. Go Kart Track and Pit Lane / karting-lp-v1: faceted grey tarmac and concrete, brushed steel, charcoal rubber, pea gravel and three painted accents in red, blue and yellow, with embedded procedural concrete maps and no custom shaders. Liveries, numbers, boards and signage are invented for this pack and copy no real series, circuit or manufacturer. Rigid node-transform clips: roll. No skinning. No collision or navigation data.

## Use with three.js

```js
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'
import { AnimationMixer } from 'three'

let mixer

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/34331/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
  mixer = new AnimationMixer(gltf.scene)
  mixer.clipAction(gltf.animations[0]).play()
})

// Call from your render loop; deltaSeconds is time since the previous frame.
function updateAssetAnimation(deltaSeconds) {
  mixer?.update(deltaSeconds)
}
```

## React Three Fiber

```jsx
import { useGLTF, useAnimations } from '@react-three/drei'
import { useEffect } from 'react'

export function KartOnTrolleyStandGoKartTrackAndPitLane(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/34331/v1/model.glb')
  const { actions, names } = useAnimations(animations, scene)
  useEffect(() => {
    const action = actions[names[0]]
    action?.reset().play()
    return () => { action?.stop() }
  }, [actions, names])
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/34331/v1/model.glb')
```

```

## Blender

```python
# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.
import bpy
bpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/34331/v1/model.glb
# Metres and +Y up are converted to Blender's Z-up scene automatically.
# Clips arrive as actions; play them from the Dope Sheet > Action Editor.
```

## Godot

```gdscript
# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.
var packed := load("res://models/model.glb") as PackedScene
var model := packed.instantiate()
add_child(model)
var player := model.find_child("AnimationPlayer", true, false) as AnimationPlayer
player.play(player.get_animation_list()[0])
```

## Unity

```csharp
// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,
// or load it at runtime straight from the CDN:
using GLTFast;
var gltf = new GltfImport();
if (await gltf.Load("https://cdn.3dassets.dev/assets/34331/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
