Common Types

Types that are commonly seen in Retro Studios file formats.

Note: Avoid linking directly to this page from articles. There's a template defined for each of the types on this page; use that instead.

Asset ID

Asset IDs are used to uniquely identify assets. They are assigned in the PAK table of contents and are used by resources to reference each other. The size of an asset ID depends on which game you're looking at:

• 32-bit IDs are used in Metroid Prime and Metroid Prime 2: Echoes.
• 64-bit IDs are used in Metroid Prime 3: Corruption and Donkey Kong Country Returns.
• 128-bit IDs are used in Donkey Kong Country: Tropical Freeze. The reason for the seemingly-unnecessary length increase is because it internally uses a new GUID system that's used commonly in a lot of different places throughout the game.

Vector3f

A Vector3f is a vector made up of three floats. Commonly used to represent a point in 3D space or a direction.

Offset	Type	Name
0x0	float	X Coordinate
0x4	float	Y Coordinate
0x8	float	Z Coordinate
0xC	End of Vector3f

AABox

An AABox is an axis-aligned bounding box formed by the minimum and maximum XYZ coordinates. Because the box is axis-aligned, all other vertices forming the box can be derived from the min/max.

Offset	Type	Name
0x0	Vector3f	Minimum Coordinate
0xC	Vector3f	Maximum Coordinate
0x18	End of AABox
