# useSideFriction

> Should friction be used on the platform sides?

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.Physics2DModule

```csharp
public bool useSideFriction { get; set; }
```

### Remarks

When false, a contact on the side uses no friction.  When true, any existing friction is used.  This is useful to stop friction slowing a [Collider2D](/engine/6000.6/script-reference/unityengine/collider2d.md) when in contact with a vertical surface when a force is being applied to keep the [Collider2D](/engine/6000.6/script-reference/unityengine/collider2d.md) in contact with the surface.  The "sides" are defined as the edges perpendicular to the "top" surface(s) in local-space.
