Schedule Random Values

Documentation

Class name: SaltScheduleRandomValues
Category: SALT/Scheduling
Output node: False

This node is designed to generate a list of random values within a specified range, optionally forcing the values to be integers. It's useful for creating randomized schedules or sequences where variability is desired.

Input types

Required

count
- Specifies the number of random values to generate, dictating the length of the output list.
- Comfy dtype: INT
- Python dtype: int
min_value
- Defines the minimum value that can be generated, setting the lower bound of the random range.
- Comfy dtype: FLOAT
- Python dtype: float
max_value
- Sets the upper limit for the random values, establishing the maximum possible value in the range.
- Comfy dtype: FLOAT
- Python dtype: float

Optional

force_integer
- Determines whether the generated random values should be integers, adding a layer of control over the output data type.
- Comfy dtype: BOOLEAN
- Python dtype: bool

Output types

schedule_list
- Comfy dtype: LIST
- The list of generated random values, adhering to the specified constraints and data type.
- Python dtype: List[float] or List[int]
