# isBuildingPlayer

> Is a player currently being built?

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.0/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public static bool isBuildingPlayer { get; }
```

### Remarks

This returns true during Player builds and AssetBundle builds.

It can be used to check the context inside script code that could be triggered during a build, for example when [ExecuteAlways](/engine/6000.0/script-reference/unityengine/executealways.md) is being used on a [MonoBehaviour](/engine/6000.0/script-reference/unityengine/monobehaviour.md).
