Serialize FP

erre · December 2016

Hi,

I have a question about serialization of FP fields.

I have tried and Unity perfectly serialize object kind:


public class MyClass : MonoBehaviour
{
[SerializeField]
private FP m_A = 0;
}

But if I have somthing like this:


public class MyClass : MonoBehaviour
{
[Serializeable]
private class InternalObj
{
[SerializeField]
private FP m_A = 0;
}

[SerializeField]
private InternalObj m_A = null;
}

it doesnt' t work and I have an exception on serialization.

How can I handle this situation? Can i Serialize a float and convert to a FP when MonoBehaviour is started?

Thank you,
Andrea.

P.S. The entire exception is:

ArgumentException: Field m_A defined on type SerializerTest+InternalObj is not a field on the target object which is of type SerializerTest.

Hello @erre, you could use the "float" approach for now, probably the next release of TrueSync will include a fix for the exception you got. Thanks for the feedback.

Hi,

Thank you. For now, I have fixed in this way:



public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
{
EditorGUI.BeginProperty(position, label, property);
EditorGUI.BeginChangeCheck();

SerializedProperty serializedValueProperty = property.FindPropertyRelative("_serializedValue");
string value = serializedValueProperty.stringValue;

// Extract number.

long l = long.Parse(value);
FP fpValue = FP.FromRaw(l);

// Editor.

fpValue = EditorGUI.FloatField(position, label, (float)fpValue);

// Serialize.

if (EditorGUI.EndChangeCheck())
{
string serializedValue = fpValue.RawValue.ToString();
serializedValueProperty.stringValue = serializedValue;
}

EditorGUI.EndProperty();
}

and it works perfectly.

Anyway, thanks for support.
