Serialization of GameObject
I found pretty much nothing from search results because I believe this never really happened to anyone. But the thing is I have precompiled dll that contains game data and therefore I cannot change the design of serialization. So, I have access to PlayerData that has all info, even ActiveBuilding (the problem), but on Serialization of PlayerData this list just doesn't produce anything...
The problem:
using (FileStream fs = new FileStream(SerializationPath, FileMode.Open))
{
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(fs, PlayerData.PDataRef);
}
Produces
"Buildings": [
{
"instanceID": 10784
}
The array that I need to be serialized (in PlayerData).
[SerializeField] public List<ActiveBuilding> Buildings = new List<ActiveBuilding>();
Active Buildings has the following structure.
public abstract class ActiveBuilding : MonoBehaviour, IUnlockable
{
[SerializeField]
private int _Free;
[SerializeField]
private int _Owned;
[SerializeField]
private double CostBase = 10;
[SerializeField]
[Tooltip("Set in editor! How much user needs to pay for building with scale.")]
private float CostScale = 1.1f;
}
Specifically referring to class inheriting ActiveBuilding solves the issue and produces...
{
"_Free": 1,
"_Owned": 1,
"CostBase": 10.0,
"CostScale": 1.100000023841858
}
I cannot refer to objects individually, because I only have 1 stream, but also because I have not access to PlayerData source. How to get around this?
For anyone who is still interested. The only proper way to address it would be to manually use reflection, collecting that data that is required. A fair and Object-Oriented way would be the method below. As there was no direct solution to this but serialization, an intermediate step needed to be done. A ShadowBuilding class was created that contains data of all relevant fields that needed to be serialized.
[Serializable]
public class BuildingShadow
{
public int Free;
public int Owned;
public double CostBase;
private float CostScale;
}
This class is constructed every time before serialization and deconstructed after deserialization.
