Value Schedule 📅🅕🅝

Documentation

• Class name: ValueSchedule
• Category: FizzNodes 📅🅕🅝/ScheduleNodes
• Output node: False

The ValueSchedule node is designed to animate values over a sequence of frames based on keyframes defined in a text input. It modulates the current frame within the maximum frame range and computes interpolated values to provide dynamic, frame-specific outputs.

Input types

Required

• text
  • A multiline string containing keyframes for animation, serving as the blueprint for generating interpolated values across frames.
  • Comfy dtype: STRING
  • Python dtype: str
• max_frames
  • The maximum number of frames for the animation, setting an upper limit for frame modulation and interpolation.
  • Comfy dtype: INT
  • Python dtype: int
• current_frame
  • The current frame number, used to determine the specific value to be output based on the animation's progression.
  • Comfy dtype: INT
  • Python dtype: int
• print_output
  • A boolean flag that, when true, prints the current frame and its corresponding value for debugging purposes.
  • Comfy dtype: BOOLEAN
  • Python dtype: bool

Output types

• float
  • Comfy dtype: FLOAT
  • The interpolated value for the current frame as a floating-point number.
  • Python dtype: float
• int
  • Comfy dtype: INT
  • The interpolated value for the current frame, cast to an integer.
  • Python dtype: int

Usage tips

• Infra type: CPU
• Common nodes: unknown
