```

### Parameters

**** (\[Ray]\(/engine/6000.0/script-reference/unityengine/ray)): 

### Returns

    Collider myCollider;

    void Start()
    {
        // Store a reference to the collider once at startup.
        myCollider = GetComponent<Collider>();
    }

    bool DetectHit(Ray ray)
    {
        return myCollider.bounds.IntersectRay(ray);
    }
}
```
