ComfyUI Node: LogicUtil_Uniform Random Int

LogicUtil_Uniform Random Int:

The LogicUtil_UniformRandomInt node is designed to generate a random integer within a specified range, providing a simple yet powerful tool for introducing randomness into your AI art projects. This node ensures that a random integer is selected between the given minimum and maximum values, and it gracefully handles cases where the minimum value is greater than the maximum by defaulting to the minimum value. This functionality is particularly useful for creating varied and dynamic outputs in generative art, where controlled randomness can lead to more interesting and unique results. By using a seed value, you can also ensure reproducibility of the random values, which is essential for consistent results in iterative design processes.

LogicUtil_Uniform Random Int Input Parameters:

min_val

min_val specifies the lower bound of the range from which the random integer will be selected. If this value is greater than max_val, the node will default to this value. The minimum value for min_val is -999999999, the maximum is 999999999, and the default is 0. This parameter allows you to control the starting point of the random selection range.

max_val

max_val defines the upper bound of the range for the random integer selection. If min_val is greater than this value, the node will default to min_val. The minimum value for max_val is -999999999, the maximum is 999999999, and the default is 1. This parameter sets the endpoint of the random selection range.

seed

seed is used to initialize the random number generator, ensuring that the sequence of random numbers can be reproduced if needed. The minimum value for seed is 0, the maximum is 9999999999, and the default is 0. This parameter is crucial for achieving consistent results across different runs, which is particularly useful in iterative design processes.

LogicUtil_Uniform Random Int Output Parameters:

INT

The output parameter is an integer (INT) that represents the randomly selected value within the specified range. This value can be used directly in your AI art projects to introduce controlled randomness, enhancing the variability and uniqueness of the generated outputs.

LogicUtil_Uniform Random Int Usage Tips:

• To ensure reproducibility of random values, always set the seed parameter to a specific value. This is particularly useful when you need consistent results across different runs.
• Use a wide range between min_val and max_val to introduce more variability in your outputs, which can lead to more dynamic and interesting results in your generative art projects.
• If you want to avoid any unexpected behavior, ensure that min_val is less than or equal to max_val. However, the node will handle cases where min_val is greater by defaulting to min_val.

LogicUtil_Uniform Random Int Common Errors and Solutions:

ValueError: min_val must be less than or equal to max_val

• Explanation: This error occurs when the min_val parameter is greater than the max_val parameter.
• Solution: Ensure that the min_val is less than or equal to max_val. If this condition is not met, the node will default to min_val, but it is good practice to set the parameters correctly to avoid confusion.

TypeError: seed must be an integer

• Explanation: This error occurs when the seed parameter is not an integer.
• Solution: Make sure to provide an integer value for the seed parameter. This ensures that the random number generator is initialized correctly.

ValueError: min_val and max_val must be integers

• Explanation: This error occurs when either min_val or max_val is not an integer.
• Solution: Ensure that both min_val and max_val are set to integer values. This is necessary for the node to function correctly and generate a random integer within the specified range.
