# Transition sequence A React block (a whole screen) in [Beamline](https://beamline.io/)'s [CMS & media](https://beamline.io/components/apps/cms-media) app. Live demo: https://beamline.io/components/transition-sequence An event's sequence of states for one object, as an inspector. The states play in order; each step between two states has its own duration and easing, while the whole sequence's delay, plays (once, a count, or until stopped, a mode of its own, never a big number) and what each repeat does (start over or go back) sit in a separate group that never changes a step. States move earlier or later by buttons, are added from the object's other states, and removed with the neighbours joined and said. A duration outside 0–30 s is said. One line totals the run, and a timeline draws the delay and each step to scale. Above it a stage draws the object in each state (lifted, glowing, pressed as they look) with each step's easing curve and duration between them; pressing a step chooses it; Play once runs a preview card through the sequence and stops (optional picture prop for the card). ## Use it for - Setting how an object moves between its states on an event (hover, press, load) in a design or animation tool. - Any ordered set of timed steps whose own timing must stay apart from the whole run's. ## Not for - Keyframes on a time ruler (a [timeline](https://beamline.io/components/timeline) editor). - Binding properties to data ([data-binding](https://beamline.io/components/data-binding)). ## Anatomy - header: the product's mark, object and event, the run's total in words - timeline: the delay and each step to scale - states in order: where it starts, each step with its timing; earlier, later, remove; add a state - step: duration and easing, this step only - whole sequence: delay, plays, each repeat ## States - one step - several steps - step chosen (outlined) - sequence plays a count, or until stopped - a removed state joins its neighbours (said) - duration missing or out of range (said, hatched) - every state used - phone: one column - right to left: the page mirrors ## Keyboard - Tab to each step and its earlier, later and remove buttons; Enter chooses a step - Duration and delay fields take arrows; plays and repeats are segmented choices ## Motion The timeline's bars ease to their new widths when a timing changes; nothing moves at rest. ## Props | Prop | Type | Default | Description | | --- | --- | --- | --- | | `object` (required) | `string` | — | | | `event` (required) | `string` | — | | | `states` (required) | `ObjectState[]` | — | Every state the object has. | | `defaultOrder` (required) | `string[]` | — | State ids in the order the sequence plays them; the first is where it starts. | | `defaultTiming` (required) | `Record` | — | The step arriving at each state, keyed by that state's id. | | `defaultSequence` (required) | `SequenceTiming` | — | | | `defaultSelected` | `string` | — | | | `onChange` | `((order: string[], timing: Record, sequence: SequenceTiming) => void)` | — | | | `product` | `string` | — | Your product's name, shown as its mark. | | `className` | `string` | — | Classes on the documented visual root; no override by default. | | `ref` | `Ref` | — | Receives the documented native target or imperative handle; omitted by default. | | `picture` | `string` | — | A picture for the object's preview (its cover image), so the states read as the real card. | ## Built from - [Avatar](https://beamline.io/components/avatar.md) - [Button](https://beamline.io/components/button.md) - [Label](https://beamline.io/components/label.md) - [Number field](https://beamline.io/components/number-field.md) - [Segmented control](https://beamline.io/components/segmented-control.md) - [Select](https://beamline.io/components/select.md) - [Spinner](https://beamline.io/components/spinner.md) - [Text morph](https://beamline.io/components/text-morph.md) - [Tooltip](https://beamline.io/components/tooltip.md) ## Import ```tsx import { TransitionSequence } from "@beamline/transition-sequence"; ``` ## Get it Transition sequence is part of Beamline UI.
