Banjo-Kazooie uses a voxel based system for handling objects and object collisions. This page outline the known object ids used to distinguish each object.

In Banjo's Backpack, these are simply listed as “Objects”. These objects are 20 bytes of attributes. These objects include:

• Actors: Objects that are given scripts to follow, typically involving multiple states. These will have a 2-byte Object Id and a 2-byte Script Id.
• Timed: Objects that perform follow a script, but are limited on how long their use is. These will have a 2-byte Object Id and a 2-byte Script Id.
• Radius: Objects that trigger when Banjo-Kazooie enter their radius. These will have a 1-byte Object Id and a 2-byte Associated Id (used for flag ids, warp ids, etc)
• Uncertain: Unsure if these items fit into a category above or require a new category.

In Banjo's Backpack, these are simply listed as “Structs”. These objects are 12 bytes of attributes. These objects include:

• Sprites: 2D Objects that will face the camera at all times (aka Billboarding).
• Static: Objects that do not change unless given accompanied by a script object.
