<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:
```
[Library( "clothing" ), AutoGenerate]
public partial class Clothing : Asset
{
[Property]⤶
public string Title { get; set; }⤶
⤶
[Property, ResourceType( "vmdl" )]⤶
⤶
public string Title { get; set; }⤶
⤶
[ResourceType( "vmdl" )]⤶
public string Model { get; set; }
⤶
[Hammer.Skip]⤶
public int Amount { get; set; }⤶
// ...
}
```
* `[Library( "clothing" )]` specifies the file extension our assets use will be .clothing
* Because we specified `[AutoGenerate]` on our asset class a .asset file will automatically generate for us.
* Properties that should be editable via the inspector in your asset should be marked with `[Property]`⤶
* Properties that should not be editable via the inspector in your asset should be marked with `[Hammer.Skip]`⤶
<note>If your Property type isn't automatically converted to a valid FGD type, use `[FGDType( "insert_type_here" )]` until it is supported.</note>
## Using the inspector
Now that you have everything set up, you can use the inspector tool to edit your first weapon.
1. Click the "Inspector" icon in the asset browser.

3. Set up your weapon however you want.

4. Save your asset into your addon's config directory - call it "MyWeapon.weapon"
## 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 `Resource.FromPath<T>`.
```
// Property allows for hot-loading
public Clothing Clothing { get; set; }
// ...
// Load the weapon data from a path
Clothing = Resource.FromPath<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 : Asset
{
// 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 );
}
}
```
