ComfyUI Node: External Number Slider (ComfyUI Deploy)

External Number Slider (ComfyUI Deploy):

The ComfyUIDeployExternalNumberSlider node is designed to provide a flexible and user-friendly way to input numerical values within a specified range in the ComfyUI environment. This node is particularly useful for AI artists who need to fine-tune parameters with precision, as it allows for the adjustment of values using a slider interface. The primary goal of this node is to facilitate the input of floating-point numbers, ensuring that the values fall within a defined minimum and maximum range. This helps in maintaining consistency and preventing errors that may arise from out-of-bound values. By using this node, you can easily control and adjust numerical parameters, enhancing the overall workflow and efficiency in your AI art projects.

External Number Slider (ComfyUI Deploy) Input Parameters:

input_id

This parameter is a string that serves as the identifier for the input number slider. It is used to reference the specific slider instance within the ComfyUI environment. The default value for this parameter is "input_number_slider". This identifier is crucial for distinguishing between different sliders when multiple instances are used.

default_value

This optional parameter is a floating-point number that sets the initial value of the slider. It allows you to define a starting point for the slider, which can be adjusted later. The default value is 0.5, and it can be incremented or decremented in steps of 0.01. This parameter ensures that the slider starts at a meaningful value, providing a convenient baseline for adjustments.

min_value

This optional parameter defines the minimum value that the slider can take. It is a floating-point number with a default value of 0, and it can be adjusted in steps of 0.01. Setting a minimum value helps in constraining the range of the slider, ensuring that the input values do not fall below a certain threshold, which can be critical for certain applications.

max_value

This optional parameter sets the maximum value that the slider can reach. It is a floating-point number with a default value of 1, and it can be adjusted in steps of 0.01. By defining a maximum value, you can prevent the slider from exceeding a certain limit, which is useful for maintaining control over the input range and avoiding potential issues with excessively high values.

External Number Slider (ComfyUI Deploy) Output Parameters:

value

The output parameter of this node is a floating-point number that represents the current value of the slider. This value is determined based on the input provided and the constraints set by the minimum and maximum values. The output is crucial for downstream processes that rely on this numerical input, as it ensures that the value is within the specified range and accurately reflects the user's adjustments.

External Number Slider (ComfyUI Deploy) Usage Tips:

• To ensure smooth and precise adjustments, set the step value to a smaller increment, such as 0.01, which allows for finer control over the slider's value.
• Use the min_value and max_value parameters to define a meaningful range for your specific application, preventing out-of-bound values that could cause errors or unexpected behavior.
• When using multiple sliders, make sure to assign unique input_id values to each slider to avoid conflicts and ensure that each slider can be referenced independently.

External Number Slider (ComfyUI Deploy) Common Errors and Solutions:

Invalid input. Returning default value: <default_value>

• Explanation: This error occurs when the input provided to the slider is not a valid floating-point number.
• Solution: Ensure that the input value is a valid number. If the input is coming from a dynamic source, add validation checks to confirm that the value is numeric before passing it to the slider.

Number out of range. Returning default value: <default_value>

• Explanation: This error happens when the input value is outside the specified range defined by min_value and max_value.
• Solution: Adjust the input value to ensure it falls within the defined range. Review the min_value and max_value settings to confirm they are appropriate for your use case.
