HasActivePlayback(handle)

説明

The HasActivePlayback Lua function returns a boolean indicating if an object has a currently active playback, for instance, if a sequence has an active cue.

引数

• handle:
  The function takes a handle of the type "light_userdata" as an argument.
  It can be omitted when using the colon notation on an object.

  The Colon Notation is a way to omit the handle as the first argument when using the Object functions.

  This is the general syntax with the colon notation: object:function()

  This is the general syntax with standard handle notation: object.function(object)

戻り値

• boolean:
  The function returns a boolean indicating the playback status:
  • true: There is active playback.
  • false: There is no active playback.

例

To return the information if the selected sequence has an active playback, create a plugin with this code:

return function()
    -- Stores the handle of the selected sequence.
    local selectedSequence = SelectedSequence()

    -- The following 'if' gives different feedback based on the playback status.
    if selectedSequence:HasActivePlayback() then
        Printf("Sequence '" ..selectedSequence.name.. "' has active playback.")
    else
        Printf("Sequence '" ..selectedSequence.name.. "' has NO active playback.")
    end
end
