Nanr_Free()

void Nanr_Free

(

NanrFile *

nanr

)

Deallocates all resources held inside a NanrFile structure.

Parameters

nanr	Pointer to structure to clear.

Nanr_GetResolvedCellId()

int Nanr_GetResolvedCellId	(	const NanrFile *	nanr,
		int	animation_index,
		int	frame_index,
		NanrFrame *	out_frame
	)

Retrieves information for a specific keyframe in a timeline sequence.

Parameters

nanr	Pointer to parsed .NANR resource structure.
animation_index	Target animation sequence index.
frame_index	Frame index inside animation sequence.
out_frame	Destination NanrFrame container to write results.

Returns

0 on success; negative value on out-of-bounds index requests.

	)

Resolves keyframe attributes at a specific tick timing step.

Parameters

nanr	Pointer to parsed .NANR resource structure.
animation_index	Target animation sequence index.
tick	Timing offset tick inside the timeline loop.
out_frame	Destination NanrFrame container to write results.

Returns

0 on success; negative value on out-of-bounds animation index.

Nanr_Parse()

int Nanr_Parse	(	const u8 *	data,
		size_t	size,
		NanrFile *	out_nanr
	)

Parses an unpacked .NANR resource block from raw bytes.

Parameters

data	Pointer to binary file data buffer.
size	Buffer size in bytes.
out_nanr	Destination NanrFile structure.

Returns

0 on success; negative value on invalid magic/formatting errors.
