## Validators

### Asset Validators

```csharp
public sealed class AssetValidatorMaterialTexture : IAssetValidator<Material>
{
    public void Validate(Material obj, List<ValidatorResult> results)
    {
        if (obj.shader == null)
            return;

        var count = obj.shader.GetPropertyCount();

        for (var i = 0; i < count; i++)
        {
            var propertyType = obj.shader.GetPropertyType(i);
            
            if (propertyType != ShaderPropertyType.Texture)
                continue;
            
            var propertyName = obj.shader.GetPropertyName(i);
            var propertyValue = obj.GetTexture(propertyName);
            
            if (propertyValue == null)
                results.Add(ValidatorResult.Create(EValidatorSeverity.Warning, $"Texture property '{propertyName}' is Null"));
        }
    }
}
```

### Game Object Validators

```csharp
public sealed class GameObjectValidatorBrokenPrefab : IGameObjectValidator
{
    public void Validate(GameObject gameObject, List<ValidatorResult> results)
    {
        if (PrefabUtility.IsPrefabAssetMissing(gameObject))
            results.Add(ValidatorResult.Create(EValidatorSeverity.Error, "GameObject is missing prefab asset"));
    }
}
```

### Component Validators

```csharp
public sealed class ComponentValidatorMeshCollider : IComponentValidator<MeshCollider>
{
    public void Validate(MeshCollider component, List<ValidatorResult> results)
    {
        if (component.sharedMesh == null)
            results.Add(ValidatorResult.Create(EValidatorSeverity.Error, "Missing mesh"));
    }
}
```

### Attribute Validators

The field attribute:
```csharp
[AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true)]
public sealed class RequiredAttribute : Attribute
{
    private readonly EValidatorSeverity _severity;

    public RequiredAttribute()
    {
        _severity = EValidatorSeverity.Error;
    }
    
    public RequiredAttribute(EValidatorSeverity severity)
    {
        _severity = severity;
    }
}
```

The validator implements `IAttributeValidator<T>`, where `T` is the attribute and will automatically be found by the validator.

```csharp
public sealed class Validator : IAttributeValidator<RequiredAttribute>
{
    public ValidatorResult Validate(RequiredAttribute attribute, object value)
    {
        var isValid = value is UnityEngine.Object obj ? obj != null : value != null;
        return isValid ? ValidatorResult.Valid : ValidatorResult.Create(attribute._severity, "Value is Null");
    }
}
```
