ComfyUI Node: LogicUtil_Random Shuffle String

LogicUtil_Random Shuffle String:

The LogicUtil_RandomShuffleString node is designed to take a list of strings, shuffle them randomly, and return the shuffled list. This node is particularly useful when you need to randomize the order of elements in a string list, which can be beneficial in various creative and procedural generation tasks. By providing a seed value, you can ensure reproducibility of the shuffle, making it possible to achieve consistent results across different runs. This node simplifies the process of randomizing string sequences, allowing you to focus on the creative aspects of your project without worrying about the underlying technical details.

LogicUtil_Random Shuffle String Input Parameters:

input_string

This parameter represents the string that contains the list of elements you want to shuffle. The elements within this string should be separated by a specific separator character. For example, if your input string is a$b$c, the elements a, b, and c will be considered for shuffling. The default value is a$b$c.

separator

The separator parameter defines the character used to split the input string into individual elements. This character should be present between each element in the input string. For instance, if your input string is a$b$c and the separator is $, the string will be split into a, b, and c. The default value is $.

seed

The seed parameter is an integer value used to initialize the random number generator. By setting a specific seed, you can ensure that the shuffle operation produces the same result each time it is run with the same input. This is useful for achieving reproducibility in your projects. The seed value can range from 0 to 9999999999, with a default value of 0.

LogicUtil_Random Shuffle String Output Parameters:

STRING

The output of this node is a shuffled list of strings. After processing the input string and shuffling its elements based on the provided separator and seed, the node returns the shuffled list. This output can be used in subsequent nodes or processes where a randomized order of elements is required.

LogicUtil_Random Shuffle String Usage Tips:

• To achieve consistent shuffling results across different runs, use the same seed value.
• Ensure that the separator character is correctly specified to match the one used in the input string.
• Use this node to randomize elements in creative projects, such as generating random sequences for procedural content.

LogicUtil_Random Shuffle String Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error occurs if the input string does not contain the specified separator, resulting in an empty list of elements.
• Solution: Verify that the input string contains the correct separator and that the separator parameter is set correctly.

ValueError: invalid literal for int() with base 10

• Explanation: This error may occur if the seed parameter is not an integer or is out of the specified range.
• Solution: Ensure that the seed parameter is an integer within the range of 0 to 9999999999.

TypeError: 'NoneType' object is not iterable

• Explanation: This error can happen if the input string is empty or not properly formatted.
• Solution: Check that the input string is not empty and is correctly formatted with the specified separator.
