Navigate to a Specific Animation Frame

Navigate to a specific frame or time and either stop or play the animation.

Usage

lottie_goToAndStop(
  value,
  isFrame = TRUE,
  name = "all",
  session = shiny::getDefaultReactiveDomain()
)

lottie_goToAndPlay(
  value,
  isFrame = TRUE,
  name = "all",
  session = shiny::getDefaultReactiveDomain()
)

Arguments

value

A numeric value specifying the frame or time to go to.

isFrame

A logical value indicating whether value is a frame number (TRUE) or time (FALSE).

name

A character string specifying the name of the 'Lottie' animation to control. The default of "all" will control all animations within the 'shiny' application.

session

The 'shiny' session object. Defaults to the current reactive domain.

Value

These functions are called for a side effect, and so there is no return value.

Details

lottie_goToAndStop moves the animation to a specific frame or time, then stops it. Sends a custom session message "lottie_js_goToAndStop" containing the function arguments.

lottie_goToAndPlay moves the animation to a specific frame or time, then continues playback. Sends a custom session message "lottie_js_goToAndPlay" containing the function arguments.
