Module ssbh_data::skel_data

Types for working with Skel data in .nusktb files.

The data for each bone is collected into a BoneData struct with a single transformation matrix. The missing matrices are recalculated when converting to Skel based on the hierarchy of BoneData.

File Differences

Unmodified files are not guaranteed to be binary identical after saving. Calculated matrices may differ from the originals due to slightly different algorithms and floating point errors. These errors are very small in practice but may cause gameplay differences such as online desyncs.

Modules

• error

Structs

• BoneData
  Data associated with a SkelBoneEntry.
• SkelData
  The data associated with a Skel file. The supported version is 1.0.

Enums

• BillboardType
  Billboarding reorients a MeshObject parented to a bone based on the camera. This effect is commonly used for 2D sprites for particles and distant objects like trees.
• BoneTransformError
  Errors while calculating BoneData transformation matrices.

Functions

• calculate_relative_transform
  Calculates the transform of world_transform relative to parent_world_transform. If parent_world_transform is None, a copy of world_transform is returned. All matrices are assumed to be in column-major order.
