# speed

> Maximum movement speed when following a path.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine.AI](/engine/6000.5/script-reference/unityengine/ai.md)
* **Assembly:** UnityEngine.AIModule

```csharp
public float speed { get; set; }
```

### Remarks

An agent will typically need to speed up and slow down as it follows a path (eg, it will slow down to make a tight turn). The speed is often limited by the length of a path segment and the time taken to accelerate and brake, but the speed will not exceed the value set by this property even on a long, straight path.
