ComfyUI Node: FL Random Number

FL Random Number:

The FL_RandomNumber node is designed to generate random numbers within a specified range, providing both integer and floating-point values. This node is particularly useful for AI artists who need to introduce randomness into their workflows, such as generating random parameters for procedural art or simulations. By allowing you to specify a range and an optional seed, the node ensures that the generated random numbers can be both controlled and reproducible. This flexibility makes it an essential tool for creating varied and dynamic outputs while maintaining the option for consistency when needed.

FL Random Number Input Parameters:

min_value

The min_value parameter sets the lower bound of the range within which the random numbers will be generated. This value can be any floating-point number between -1000000.0 and 1000000.0, with a default of 0.0. Adjusting this parameter allows you to control the minimum possible value of the generated random numbers, which is useful for ensuring that the output stays within a desired range.

max_value

The max_value parameter sets the upper bound of the range for the random number generation. Similar to min_value, this can be any floating-point number between -1000000.0 and 1000000.0, with a default of 1.0. This parameter is crucial for defining the maximum possible value of the generated random numbers, allowing you to tailor the output to specific needs.

seed

The seed parameter is an integer that initializes the random number generator to ensure reproducibility. It can range from 0 to 1000000, with a default value of 0. When set to 0, a random seed is generated automatically. Using a specific seed value allows you to produce the same sequence of random numbers across different runs, which is useful for debugging or when consistent results are required.

FL Random Number Output Parameters:

INT

The INT output is a randomly generated integer within the specified range defined by min_value and max_value. This output is useful for scenarios where whole numbers are needed, such as selecting random indices or generating discrete values for procedural content.

FLOAT

The FLOAT output is a randomly generated floating-point number within the specified range defined by min_value and max_value. This output is ideal for applications requiring continuous values, such as randomizing parameters in a smooth gradient or generating noise values for textures.

FL Random Number Usage Tips:

• To ensure reproducibility in your projects, set a specific seed value. This will allow you to generate the same random numbers each time you run the node.
• Use a wide range for min_value and max_value to introduce more variability in your outputs, which can be particularly useful for creating diverse procedural art.
• If you need both integer and floating-point random values, this node provides both in a single execution, saving you the need to use multiple nodes.

FL Random Number Common Errors and Solutions:

ValueError: min_value should be less than or equal to max_value

• Explanation: This error occurs when the min_value parameter is set higher than the max_value parameter.
• Solution: Ensure that the min_value is less than or equal to the max_value to avoid this error.

ValueError: Directory path is not provided.

• Explanation: This error is not directly related to the FL_RandomNumber node but may appear if the node is used in conjunction with other nodes requiring a directory path.
• Solution: Ensure that all required parameters for other nodes in your workflow are correctly set, particularly those requiring a directory path.
