09. Playback and player widgets

The Trial object may also contain a Playback object, which can refer to one of the following player widgets:

• Autoplay (plays and optionally shows an animation)
• PlayButton (starts audio on click)
• ImagePlayer (a special case of PlayButton, can show an image aligned with the button_
• MultiPlayer (multiple PlayButtons)
• MatchingPairs (showing PlayButtons as cards, and perform special logic every time the user selects a "pair")

Initalizing a Playback object

An example of how a Playback object is initalized in the Python backend:

playback = PlayButton(
   [section]
)

The only required argument for Playback objects is an array of audio sections. For Autoplay, PlayButton and ImagePlay, the first (and only) section in the array is used automatically. For MultiPlayer and MatchingPairs, the participant can control which section is being played by interacting with buttons or cards.
