Spongebob Squarepants: Battle For Bikini Bottom works by using assets, which can be different formats such as models, textures, animations, object placement information, and many others. Assets are defined by AHDR sections in the HIP archives and uniquely identified by their Asset ID. It is not yet known what all different asset types do.

Classes of Assets

There are many different asset types, but they can be grouped into classes that have similar properties.

Renderware Streams

These are assets whose data is composed of a Renderware binary stream, with the tree structure commonly found in them. These assets can be opened in RW Analyze. They are: BSP, JSP, MODL, RWTX.

Object Assets

Object assets are a class which start with the following 8 byte header, and are able to send and recieve events.

Offset Type Variable Description
0x00 AssetID Asset ID Asset ID of entry. Should match the asset ID of the asset in the AHDR.
0x04 byte Object ID Unique to each object type. The asset table below shows the object ID for each type.
0x05 byte Number of Events
0x06 short Flags Common flags represented as a 16-bit bitfield although only the 5 lowest bits are ever used.
  • 1 - Enabled - Initial enabled/disabled state. 0 = disabled, 1 = enabled
  • 2 - Enabled on Scene Prepare - If this asset ever gets disabled, this flag ensures that it gets re-enabled during every scene prepare (player respawn, level reload, etc.)
  • 4 - unknown - Always 1
  • 8 - unknown
  • 16 - Receive Shadows - Used by some placeable asset types but not all. Asset types known to use this flag: BUTN, PLAT, SIMP

The data that follows this header differs depending on the asset type. Some object assets are placeable assets as well (defined below).

These objects have, at the end of their data, an array of events, with the amount of entries specified in this header. The only exception for this is the PLYR assets, which still has one field after the events.

Placeable Assets

Placeable assets are object assets which have a 3D placement in the world and the following common header (not all objects with a position follow this, though; for example, MRKR have a position but are not even object assets). They start with the 8 byte object asset header detailed above, then are followed by this:

Offset Type Variable Description
0x08 byte Visibility flags Flags stored in a bitfield, most likely related to visibility. Can be changed dynamically mid-game through events. (?) Always 1 for BOUL and PLYR.
0x09 byte Type flags Defines the subtype of the asset. Usually 0 except for the asset types listed below.
0x0A byte Unknown flags Always 0.
0x0B byte Solidity flags Flags stored in a bitfield, most likely related to collision. Can be changed dynamically mid-game through events. (?) Always 0 for BOUL, PLYR, and TRIG.
0x0C int Unknown Always null. Not present in some versions of placeable assets, mainly beta/unused assets and non-BFBB assets.
0x10 AssetID (SURF) Surface Surface for SIMP, PLAT, UI, EGEN, and possibly others.
0x14 Vector3 Rotation A (Y, X, Z) rotation vector (in radians).
0x20 Vector3 Position A (X, Y, Z) position vector.
0x2C Vector3 Scale A (X, Y, Z) scale vector.
0x38 Vector4 Color A (R, G, B, A) color vector (values range from 0 to 1). Usually (1.0, 1.0, 1.0, 1.0) in all types.
0x48 float Unknown Usually 255.0 in all types.
0x4C AssetID (MODL/MINF) Model Model for SIMP, VIL, PLAT, PKUP, TRIG, DSTR, BUTN, UI, BOUL, EGEN, PLYR, and possibly others.
0x50 AssetID (ALST/ANIM/SND) Animation/Sound Animation/animation list for SIMP, PLAT, DSTR, and possibly others. Sound for UI.
