AnchorSave

AnchorSave is a lightweight, JSON-based save system for Unity.

It is designed to be simple, explicit, and safe, without using deprecated APIs like BinaryFormatter, reflection-heavy magic, or opaque serialization pipelines.

If you want full control over what gets saved — and the ability to inspect and debug save files — AnchorSave is built for that.

How It Works

AnchorSave follows a simple rule:

Only objects that implement ISaveable are saved.

Each saveable object:

• Provides a stable UID
• Returns a plain serializable data structure
• Restores itself from JSON during load

The save system:

• Iterates over all active ISaveable components
• Stores their data as JSON, keyed by UID
• Restores state by matching UIDs on load

There is no automatic scene scanning, guessing, or hidden behavior.

Example

public class Player : MonoBehaviour, ISaveable
{
    public string UID => "Player";

    public object CaptureState()
    {
        return new PlayerSaveData
        {
            position = new float[]
            {
                transform.position.x,
                transform.position.y,
                transform.position.z
            }
        };
    }

    public void RestoreState(object state)
    {
        PlayerSaveData data =
            JsonUtility.FromJson<PlayerSaveData>((string)state);

        transform.position = new Vector3(
            data.position[0],
            data.position[1],
            data.position[2]
        );
    }
}
