ComfyUI Node: 📈 Smooth Event Curve

Smooth Event Curve [Dream]:

The Smooth Event Curve [Dream] node is designed to create a smooth transition effect over a specified period within an animation. This node is particularly useful for generating smooth, non-linear changes in values, which can be applied to various animation parameters to achieve more natural and visually appealing results. By defining a center point and a width for the transition, the node calculates a smooth curve that gradually increases to a peak and then decreases, ensuring a seamless and aesthetically pleasing effect. This is especially beneficial for animations that require gradual changes rather than abrupt shifts, enhancing the overall fluidity and realism of the motion.

Smooth Event Curve [Dream] Input Parameters:

max_value

This parameter defines the maximum value that the curve will reach at its peak. It determines the highest point of the smooth transition. The default value is 1.0, and it accepts floating-point numbers.

min_value

This parameter sets the minimum value of the curve, which is the starting and ending point of the transition. It ensures that the curve smoothly returns to this value after reaching the peak. The default value is 0.0, and it accepts floating-point numbers.

width_seconds

This parameter specifies the duration of the transition in seconds. It defines the total width of the curve, from the start to the end of the smooth transition. The default value is 1.0 seconds, with a minimum value of 0.1 seconds.

center_seconds

This parameter indicates the center point of the transition in seconds. It is the time at which the curve reaches its peak value. The default value is 10.0 seconds, with a minimum value of 0.0 seconds.

Smooth Event Curve [Dream] Output Parameters:

FLOAT

This output represents the calculated value of the smooth curve at the current time. It is a floating-point number that varies smoothly between the min_value and max_value based on the defined parameters.

INT

This output is the integer representation of the FLOAT output. It provides a rounded integer value of the smooth curve at the current time, which can be useful for applications requiring discrete values.

Smooth Event Curve [Dream] Usage Tips:

• To create a smooth fade-in and fade-out effect, set the center_seconds to the midpoint of your desired transition period and adjust the width_seconds to cover the entire duration of the transition.
• Experiment with different max_value and min_value settings to achieve the desired intensity and range of the smooth transition.

Smooth Event Curve [Dream] Common Errors and Solutions:

"Invalid value for width_seconds"

• Explanation: The value provided for width_seconds is below the minimum allowed value of 0.1 seconds.
• Solution: Ensure that the width_seconds parameter is set to a value of 0.1 seconds or higher.

"Invalid value for center_seconds"

• Explanation: The value provided for center_seconds is below the minimum allowed value of 0.0 seconds.
• Solution: Ensure that the center_seconds parameter is set to a value of 0.0 seconds or higher.

"File not found for wav_path"

• Explanation: The specified file path for the WAV file does not exist.
• Solution: Verify that the file path is correct and that the file exists at the specified location.
