OBJS - Serialized script objects
By Tiger
The data is divided into four sections
Contents |
Data sections
Header (28 bytes)
DWORD version? - currently 0x00000500
DWORD magic value - ("OBJS")
DWORD count1 - Count of defined object types
DWORD count2 - Count of number of saved instances
DWORD - Offset from the start of the header of the type definitions
DWORD - Offset from the start of the header to the instance pointer table
DWORD - Offset from the start of the header to a TGI index
Instances
count2 (above) entries:
BYTE - Data type
{Data}
See below for the types of data and the format of the data. Most common here are 0x10 and 0x11, but boxed value types can appear here as well, for example when a number or enum is added to a System.List<System.Object> collection.
Instance index
count2 repeats of DWORD - Pointer to the start of the serialized instance data This index is 1 based, with the first entry referenced as entry 1. 0 is reserved to indicate null references
Type definitions
Very loosely structured data, with lots of flags and optional values including count1 entries
Each entry consists of
TYPE_SIGNATURE {TYPE_METHODS | INTERFACE}
TYPE_SIGNATURE =
[TYPE_MODIFIERS] [GENERIC_DEFINITION] NAMESTRING
TYPE_MODIFIERS =
[DUPLICATE_DEFINITION] [GENERIC_PARAMETERS] NULLBYTE
DUPLICATE_DEFINITION = 0x02
GENERIC_PARAMETERS = 0x2x where x is gemeric parameter count - 1
GENERIC_DEFINITION = x+1 (If x was specified) repeats of
TYPE_SIGNATURE
NAME =
CHAR_COUNT BYTE(With CHARCOUNT repeats)
CHAR_COUNT =
BYTE [BYTE] (7 bit MSB order bytes, with the high bit indicating continuation)
TYPE_METHODS =
METHOD_COUNT [(1..N)METHOD_DEFINITION]
METHODCOUNT =
BYTE [BYTE] (7 bit MSB order bytes, with the high bit indicating continuation and the first byte having a 7 bit value no higher than 0x3f)
METHOD_DEFINITION =
NAME PRIMITIVE_TYPE
PRIMITIVE_TYPE =
BYTE (See section below)
INTERFACE =
0x7F
Generic parameter definitions can be nested in the data structure, as would be required by System.Dictionary<System.UInt32,System.List<Sims3.CAS.SimDescription>>
Some types do not list any fields even though they have them. In general, types listed with fields are any generic type serialized using reflection. Some types have special serialization handlers, in which case the format is hard coded rather than described. An example of hard coded types is delegates, or the root type ScriptCore.
TGI
DWORD count5 - count of TGI entries TGI entries, in standard order
Primitive Types
Defined in ScriptCore.PersistedTypeCode
| Byte | Type of data | Data format | Notes | |
|---|---|---|---|---|
| 0x00 | Null | |||
| 0x01 | Reference | DWORD of instance ID | ||
| 0x02 | Boolean | BYTE | 0 for false, 1 for true | |
| 0x03 | Byte | BYTE | ||
| 0x04 | Char | Unknown | ||
| 0x05 | DateTime | QWORD | System.DateTime FromBinary() and ToBinary() format | |
| 0x06 | Decimal | Unknown | ||
| 0x07 | Double | QWORD | ||
| 0x08 | Short | WORD | ||
| 0x09 | Int | DWORD | ||
| 0x0A | Long | QWORD | ||
| 0x0B | SByte | BYTE | Signed byte | |
| 0x0C | Single | DWORD | Single precision floating point number | |
| 0x0D | Ushort | WORD | Unsigned | |
| 0x0E | Uint | DWORD | Unsigned | |
| 0x0F | Ulong | QWORD | Unsigned | |
| 0x10 | Object | DWORD type Various data |
Type references a defined structure, with the fields for that object immediately following
Usually appears as the type of an instance, but it can appear in the middle of formatted data to represent a non-system defined value type (IE a struct) | |
| 0x10 | Object | DWORD type Count * DWORD instance reference |
When in the context of an array (Type 0x11) | |
| 0x11 | Array | DWORD Length BYTE Primitive type |
Referenced by most single member collection classes as well (List, ArrayList, Queue, Stack, etc) | |
| 0x12 | Type Zero based | Unknown | Assume this is like the one based, but the values are 1 lower. Not seen in the wild. | |
| 0x13 | Broken Protected Object | Unknown | ||
| 0x14 | External Object | Unknown | ||
| 0x15 | Broken Enum | Unknown | ||
| 0x16 | Protected Object | BYTE length DWORD type |
Stores "protected" objects in an opaque manner. Currently only seen referring to DriverHandleWrapper class. | |
| 0x17 | Enum | BYTE+ Type of enum (BYTES) optional additional as needed for the size of the type ID |
The length is encoded as 7 bits, with the high bit indicating the value continues to further bytes. The value is in MSB order (Opposite normal byte order) | |
| 0x18 | Method | DWORD DWORD DWORD DWORD |
Used to encode MethodInfo from a delegate | |
| 0x19 | ResKey | DWORD | Index into the TGI table. | Corresponds to Sims3.SimIFace.ResourceKey |
| 0x1A | Type One Based | BYTE+ (BYTE)s as needed for the type ID |
Corresponds to System.Type, and references the type by ID Same format used for Enum definition where it encodes the type of the enum |
