### Additions
- Automatically opts-out `Item/Mobile/Guild/Accounts` from dirty checking with a new property `UseDirtyChecking`
- Codegen now enables `UseDirtyChecking` via getter. This requires that the property is `virtual` for derived types.
### Fixes
- Fixes `EncodedInt` being broken
- Fixes issues with new custom serializable types that are not derived from Item/Mobile/etc.
- Removes double dirty checking.
### Example of a brand new serializable type that isn't an Item/Mobile/etc.
User created code:
```cs
using System;
namespace Server.Items
{
[Serializable(0)]
public partial class NewTestEntityObject : ISerializable
{
[EncodedInt]
[SerializableField(0)]
private int _someProperty;
public NewTestEntityObject()
{
SetTypeRef(GetType());
// Add to serial tracking like World.Item
/*
Serial = World.NewEntity;
World.AddEntity(this);
*/
}
[AfterDeserialization]
private void AfterDeserialization()
{
Console.WriteLine("This ran!");
}
public int TypeRef { get; }
public Serial Serial { get; }
public void Delete()
{
}
public bool Deleted { get; set; }
public void SetTypeRef(Type type)
{
// Type tracking for persistence goes here
/*
TypeRef = World.NewEntityTypes.IndexOf(type);
if (TypeRef == -1)
{
World.NewEntityTypes.Add(type);
TypeRef = World.NewEntityTypes.Count - 1;
}
*/
}
}
}
```
Generated code:
```cs
namespace Server.Items
{
public partial class NewTestEntityObject
{
#pragma warning disable 0414
private const int _version = 0;
#pragma warning restore 0414
public int SomeProperty
{
get => _someProperty;
set
{
if (value != _someProperty)
{
_someProperty = value;
((ISerializable)this).MarkDirty();
}
}
}
long ISerializable.SavePosition { get; set; } = -1;
BufferWriter ISerializable.SaveBuffer { get; set; }
bool ISerializable.UseDirtyChecking => true;
public NewTestEntityObject(Serial serial)
{
Serial = serial;
SetTypeRef(typeof(NewTestEntityObject));
}
public void Serialize(IGenericWriter writer)
{
writer.WriteEncodedInt(_version);
writer.WriteEncodedInt(SomeProperty);
}
public void Deserialize(IGenericReader reader)
{
var version = reader.ReadEncodedInt();
SomeProperty = reader.ReadEncodedInt();
Timer.DelayCall(AfterDeserialization);
}
}
