Methods

AnimationLength()

Calculates the keyframe length of the animation based on the maximum number of position, rotation, and scaling keyframes among all bones.

Declaration
public int AnimationLength()
Returns
Type Description
int

The maximum number of keyframes (positions, rotations, or scalings) among all bones; if no bones are present, returns -1.
Remarks

This method iterates through all bones to determine the maximum keyframe length.

FindBone(string)

Finds a bone with the specified name.

Declaration
public Bone FindBone(string name)
Parameters
Type Name Description
string name
Returns
Type Description
Bone

GetKeyFrameIndex(float)

Gets the keyframe index at a specific animation time based on the first bone.

Declaration
public int GetKeyFrameIndex(float animationTime)
Parameters
Type Name Description
float animationTime

The time within the animation to find the keyframe index for.
Returns
Type Description
int

The highest keyframe index (position, rotation, or scale) at the specified animation time.
Remarks

This method assumes that all keyframe lists (positions, rotations, scales) are synchronized and have the same number of keyframes. It calculates the keyframe index for the first bone in the list.
