# Item Switch System

## Item Switch Input Configuration

The Item Switch system is controlled by the JU Character Controller and JU Inventory, they use the **Player Character Inputs** Asset file to call the item switch functions.

Here you can configure how you want your game's item exchange functions to be called:

## How to use Slot/Sequential Item Switching

Sequential Item switching is seen in many shooting games where you have a primary, secondary, tertiary weapon... it is possible to have this mechanic using the Sequential Item Switch system.

&#x20;The item switching sequence is set in the **Sequence Slot** in the **JU Inventory** script.&#x20;

You can drag and drop items into each slot to set the default sequence.

## How to use UI Slot to set Sequential Switch order

You can use UI Inventory Slots to set primary, secondary, tertiary weapons...

You can also configure the **Inventory Slot UI** to only accept certain tag types, for example only accept large weapons as primary weapons and small weapons as secondary weapons.

## Item Switching by code

To swtich items with a code is simple, the example code below switches items with a timer.

{% code title="SwitchItemByScriptSample.cs" lineNumbers="true" %}

```csharp
using UnityEngine;
using JUTPS; // <-- Use JUTPS Lib
public class SwitchItemByScriptSample : MonoBehaviour
{
    public float SecondsToSwitchItem = 2;
    public JUCharacterController JUCharacter;
    void Start()
    {
        // >>> Call the function at the given time repeatedly 
        InvokeRepeating(nameof(SwitchToNextItem), SecondsToSwitchItem, SecondsToSwitchItem);
    }
    private void SwitchToNextItem()
    {
        // >>> Call Next Item Switch function by JUCharacterController
        JUCharacter.SwitchToNextItem();
    }
}
```

{% endcode %}

### Switching Methods:

<pre class="language-csharp" data-full-width="false"><code class="lang-csharp">
<strong>// >>> Call next item
</strong>JUCharacter.SwitchToNextItem();

// >>> Call previous item
JUCharacter.SwitchToPreviousItem();

// >>> Switch to specific item in right hand
JUCharacter.SwitchToItem(id: 2, RightHand: true);

// >>> Switch to sequential slot item
JUCharacter.SwitchToItemInSequentialSlot(JUTPS.InventorySystem.JUInventory.SequentialSlotsEnum.third);

</code></pre>
