<title>Custom Asset Types</title>
Custom assets are things you can define yourself. They give you a nice inspector window and they're hotloaded in-game, which means you can whip things up pretty quickly if you're using them.
You can find plenty of examples of assets throughout s&box, here's a snippet from the clothing asset:
```
[GameResource("Clothing Definition", "clothing" )]
public partial class Clothing : GameResource
{
public string Title { get; set; }
[ResourceType( "vmdl" )]
public string Model { get; set; }
[HideInEditor]
public int Amount { get; set; }
// ...
}
```
* `[GameResource("Clothing Definition", "clothing" )]` specifies the file extension our assets use will be .clothing
* Properties that should not be editable via the inspector in your asset should be marked with `[HideInEditor]`
* You can mark properties with specific categories using `[Category("Example Category")]`

<note>If your Property type isn't automatically converted to a valid FGD type, use `[FGDType( "insert_type_here" )]` until it is supported.</note>⤶

### How to use [ResourceType]
ResourceType supports specifying the file extension of a resource you want to use, which will add a navigator to the inspector.
Examples:
* `[ResourceType( "png" )]`
* `[ResourceType( "vmdl" )]`.
In addition, it also supports asset files, including custom ones. e.g. `[ResourceType( "sound" )]` or `[ResourceType( "clothing" )]`.
## Using the inspector
Now that you have everything set up, you can use the inspector tool to edit your first weapon.
1. Go to the "Assets Browser" tab in the s&box editor.
2. Right click a folder in your addon and click "Add X Definition". Typically you'd want to put these in some sort of `data` folder.
<upload src="aa125/8da3ac2bed7fc93.png" size="26483" name="image.png" />
3. Enter a name for your asset
<upload src="aa125/8da3ac1fd392295.png" size="6257" name="image.png" />
4. Go to the "Inspector" tab and set your asset up how you want it.
5. Click the save button (looks like a floppy disk) to save your asset.
## Accessing assets
All assets are loaded when you first start the game, there are several ways you can access them:
### FromPath
When assets are loaded they are stored in a dictionary with their path, you can access these with `Asset.FromPath<T>`.
```
// Property allows for hot-loading
public Clothing Clothing { get; set; }
// ...
// Load the weapon data from a path
Clothing = ResourceLibrary.Get<Clothing>( "config/tshirt.clothing" );
```
### PostLoad
When assets are loaded they call their PostLoad method, you can use this to store a list of your assets for later use.
```csharp
public partial class Clothing : GameResource
{
// Access these statically with Clothing.All
public static IReadOnlyList<Clothing> All => _all;
internal static List<Clothing> _all = new();
protected override void PostLoad()
{
base.PostLoad();
if ( !_all.Contains( this ) )
_all.Add( this );
}
}
```
