# kTweenSequenceElement

An atom that specifies an entry in a tween sequence.

## Overview

Overview Its parent is the tween QT atom container (which you specify with the constant kParentAtomIsContainer). The ID of a kTweenSequenceElement atom must be unique among the kTweenSequenceElement atoms in the same QT atom container. The index of a kTweenSequenceElement atom specifies its order in the sequence; the first entry in the sequence has the index 1, the second 2, and so on. This atom is a leaf atom. The data type of its data is TweenSequenceEntryRecord, a data structure that contains the following fields:
