# Sandbox.BaseInventoryComponent.ManualPumping

```csharp
bool ManualPumping { get; set; }
```

By default the inventory pumps the active item's control every frame in its own update. Turn
this on to take over that timing yourself - the inventory will stop pumping and you call
[Sandbox.BaseInventoryComponent.Pump](/api/Sandbox.BaseInventoryComponent/Pump) from wherever you want (e.g. alongside your player's own input handling).

Declared in [Sandbox.BaseInventoryComponent](/api/Sandbox.BaseInventoryComponent).
Assembly: `Sandbox.Engine`.
