# MapSet (Multiple maps)

To localize a user on a specific mapSet, provide the MapSet Code where the user is located. Retrieve the mapSetID by logging into the Developer Portal or using our REST API

In the Map Localization Manager in Unity SDK, select Localization Type as "Mapset" and then past your mapSetID

### Add MapSet Mesh in Unity to visualize your Mesh

Download the combined Mesh from the developer portal and add it in Unity SDK to visualize your maps

### Update MapSet Code in Runtime

To dynamically change the mapOrMapsetCode at runtime in your existing script, you can create a UI input field or a method that updates the mapOrMapsetCode in the MapLocalizationManager. Below is an example script showcasing how to do this via a simple button press or direct method call.

```csharp
using MultiSet;
using UnityEngine;
using UnityEngine.UI;

public class MapSetCodeUpdater : MonoBehaviour
{
    // Reference to the Map Localization Manager
    private MapLocalizationManager mapLocalizationManager;

    // Input field to get the new Map ID from the user
    [SerializeField]
    private InputField mapCodeInputField;

    void Start()
    {
        // Find the Map Localization Manager component in the scene
        mapLocalizationManager = FindObjectOfType<MapLocalizationManager>();

        if (mapLocalizationManager == null)
        {
            Debug.LogError("MapLocalizationManager not found! Please ensure it is added to the scene.");
        }

        if (mapCodeInputField == null)
        {
            Debug.LogError("InputField reference is missing! Please assign it in the inspector.");
        }
        
        mapLocalizationManager.localizationType = LocalizationType.Mapset;
    }

    // Method to update the Map ID
    public void UpdateMapId()
    {
        if (mapLocalizationManager != null && mapCodeInputField != null)
        {
            string newMapCode = mapCodeInputField.text;

            if (!string.IsNullOrWhiteSpace(newMapCode))
            {
                mapLocalizationManager.mapOrMapsetCode = newMapCode;
                Debug.Log($"Map Code updated to: {newMapCode}");
            }
            else
            {
                Debug.LogWarning("Map Code cannot be empty! Please enter a valid Code.");
            }
        }
    }
}
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://multiset.gitbook.io/multiset/unity-sdk/on-cloud-localization/mapset-multiple-maps.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
