# Entrance Barrier (Caravan Park and Campsite)

A 4.2 m site entrance barrier: a galvanised pedestal on a concrete base with a striped arm and a counterweight, and a drop leg under the far end. The arm is one node on the pedestal axis, so the clip tilts it up to let a tourer through and drops it again. The pedestal is fixed.

## About

A 4.2 m site entrance barrier: a galvanised pedestal on a concrete base with a striped arm and a counterweight, and a drop leg under the far end. The arm is one node on the pedestal axis, so the clip tilts it up to let a tourer through and drops it again. The pedestal is fixed. Overall 4.565 x 1.290 x 0.700 m (X x Y x Z), metre units, +Y up, +Z forward, resting on y=0. Named nodes on their own pivots: arm. Caravan Park and Campsite / holidaypark-lp-v1: mown grass, concrete hardstanding, cream caravan shell, sawn timber, galvanised steel and charcoal glazing, with the orange and blue of awnings, tents and site signage carrying the colour, embedded procedural timber and concrete maps and no custom shaders. Rigid node-transform clips: open and close. 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/35379/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 EntranceBarrierCaravanParkAndCampsite(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/35379/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/35379/v1/model.glb')
```

## <model-viewer>

## 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/35379/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/35379/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
