# \[Old Versions] How to switch between items

## Item Switch Manager

This script controls the item switching system of the characters. It is possible to switch items by scrolling the mouse, sequentially with numbers on the alphanumeric keyboard, and by pressing the next/previous button.

## How to use Sequential Item Switching

The item switching sequence is set in the **Sequence Slot** in the Inventory Component. You can drag and drop items into each slot and it will work normally.

Or you can use Slots in the UI to set items in sequence:

{% hint style="info" %}
It is important to note that unlike **Sequential Item Switching**, the item switching order is in the order of position in the Hierarchy(inside player bone hand) by default.

## Switching by code

To switching an item for a code is simple, the below example code checks when you press the G key and switch items to the next one.

{% code lineNumbers="true" %}

```csharp
using UnityEngine;
public class SwitchOnPressGKeyExample : MonoBehaviour
{
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.G)) 
        {
            ItemSwitchManager.NextPlayerItem();
        }
    }
}
```

{% endcode %}

Some static methods you can use in code for item switching:
