# Selection Manager

## Introduction

{% hint style="info" %}
Part of the [Selection System](https://kb.heathen.group/old-kb/toolkit-for-ui-and-ux/unity/learning/core-concepts/selection-system) of the UX Complete asset
{% endhint %}

This component simply exposes the selection changed event to the Unity Inspector and a selection of the common selection funcitons.

{% hint style="success" %}
Selection Manager is a .NET IColleciton of SelectableObjects ... this means you can iterate over it to iterate over the selected objects

```csharp
foreach(var selected in selectionManager)
{
    Debug.Log(selected.name + " is selected");
}
```

{% endhint %}

### Funcitons

{% hint style="warning" %}
This simply operates the [API.Selection](https://kb.heathen.group/old-kb/toolkit-for-ui-and-ux/unity/api/selection) interface. The interface its self has far more useful funcitons such as searching of selected objects and more.

You are strongly encuraged to use [API.Selection](https://kb.heathen.group/old-kb/toolkit-for-ui-and-ux/unity/api/selection) directly.
