This page explains serialisation using SCR_JsonSaveContext/SCR_JsonLoadContext and SCR_BinSaveContext/SCR_BinLoadContext.


JSON

Serialisation

SCR_JsonSaveContext saveContext = new SCR_JsonSaveContext(); string stringValue = "data"; int integerValue = 123; saveContext.WriteValue("key1", stringValue); saveContext.WriteValue("key2", integerValue); // process saved data (export, send, save...), in this case data are exported as json string string dataString = saveContext.ExportToString();

Deserialisation

SCR_JsonLoadContext loadContext = new SCR_JsonLoadContext(); loadContext.ImportFromString(dataString); string stringValue; int integerValue; // order does not matter for JSON as it uses key names loadContext.ReadValue("key2", integerValue); loadContext.ReadValue("key1", stringValue);


Binary

Serialisation

SCR_BinSaveContext saveContext = new SCR_BinSaveContext(); string stringValue = "data"; int integerValue = 123; saveContext.WriteValue("key1", stringValue); saveContext.WriteValue("key2", integerValue); // process saved data (export, send, save...), in this case data are saved to "file.bin" saveContext.SaveToFile("file.bin");

Deserialisation

SCR_BinLoadContext loadContext = new SCR_BinLoadContext(); loadContext.LoadFromFile("file.bin"); string stringValue; int integerValue; // order matters for Binary serialisation, as Binary ignores names loadContext.ReadValue("key1", stringValue); loadContext.ReadValue("key2", integerValue);


Object Serialisation

Simple

The following class set to serialise will serialise all its properties.

Data structures that shall be serialised are not allowed to have parameters in their constructor, otherwise they can not be read back.

class MyClass : Managed { protected int m_iVariable = 42; protected string m_sVariable; protected float m_fVariable = 33.3; }

NonSerialized

Adding the NonSerialized() decorator to a field will make the serialisation ignore it.

class MyClass : Managed { protected int m_iVariable = 42; protected string m_sVariable = "Hello there"; [NonSerialized()] protected float m_fVariable = 33.3; }

Advanced

The following methods allow to define a custom serialisation per class. This is useful to avoid saving lengthy yet useless information for loading as well as load values in a certain order.

The NonSerialized decorator is only useful with the simple object serialisation - SerializationSave/SerializationLoad will ignore it.

SerializationSave

If an object has the SerializationSave method defined, the SaveContext will use it and not process object's properties automatically at all.

class MyClass : Managed { protected int m_iVariable = 42; protected string m_sVariable = "Hello there"; protected float m_fVariable = 33.3; bool SerializationSave(BaseSerializationSaveContext context) { if (!context.IsValid()) return false; context.WriteValue("theString", m_sVariable); context.WriteValue("integer", m_iVariable); context.WriteValue("floatingpoint", m_fVariable); return true; } }

SerializationLoad

If an object has the SerializationLoad method defined, the SaveContext will use it and not process object's properties automatically at all.

class MyClass : Managed { protected int m_iVariable = 42; protected string m_sVariable = "Hello there"; protected float m_fVariable = 33.3; bool SerializationLoad(BaseSerializationLoadContext context) { if (!context.IsValid()) return false; context.ReadValue("theString", m_sVariable); context.ReadValue("integer", m_iVariable); context.ReadValue("floatingpoint", m_fVariable); return true; } }
