# Inputs
Managing player inputs can quickly become overwhelming. Essential Systems streamlines the process with Inputs, making changes and customization effortless.
To handle all inputs we use the `Input Manager` script. You can add this to any game object in the scene hierarchy (it will become `DontDestroyOnLoad` scene gets loaded.
{% hint style="warning" %}
There **must** always be exactly **one** `Input Manager` at any time.
{% endhint %}
To actually assign inputs and keybindings we create and use `Input` objects. You can create your own by right-clicking anywhere in the project and go to `Create/Essentials/Inputs//Input`. This will create a new `Input` object where you can define which keys/reference to Input Action Asset. One `Input` can contain multiple keys that all maps to the same action.
### Standard Input System
The `Input` object also comes with a `Scheme` property. This is where you can define where the input can be used.
### New Input System
Here, we do **not** provide a `Scheme` property. Instead, you **must** add **all** `EScheme` entries to the `Action Map` in the `Player Input` with the **exact** same name and casing.
An `EScheme` is a way for you to tell the `Input Manager` what scope it should listen to inputs in. For example; if you have a pause menu and you pause the game, you may only want to listen to UI inputs and ignore all player inputs. This can be done using `Scheme`.
To set the current `Scheme` in runtime, you can simply call:
```csharp
InputManager.Scheme = EScheme.UI; // UI can be changed to anything (PLAYER, etc.)
```
By default, only two pre-made schemes are available, `UI` and `DEFAULT`. You can add your own by opening the `Input Manager` script. At the top of the script, you will find an enum; `EScheme`. Here you can simply add your entry (if you are using the `New Input System` you must also add it to the `Action Map`).
