ComfyUI Node: 📈 Triangle Event Curve

Triangle Event Curve [Dream]:

The Triangle Event Curve [Dream] node is designed to generate a triangular waveform that can be used to modulate various parameters over time in your animations. This node is particularly useful for creating smooth, cyclical transitions between two values, making it ideal for effects that require a gradual increase and decrease, such as pulsing lights or oscillating movements. By defining the peak and trough values, as well as the duration and center point of the waveform, you can precisely control the timing and amplitude of the curve, allowing for highly customizable and dynamic animations.

Triangle Event Curve [Dream] Input Parameters:

max_value

This parameter sets the maximum value of the triangle waveform. It determines the peak of the curve, which is the highest point the waveform will reach. The default value is 1.0, and it can be adjusted to any floating-point number to fit your specific needs.

min_value

This parameter sets the minimum value of the triangle waveform. It determines the trough of the curve, which is the lowest point the waveform will reach. The default value is 0.0, and it can be adjusted to any floating-point number to fit your specific needs.

width_seconds

This parameter defines the total duration of the triangle waveform in seconds. It controls how long it takes for the waveform to go from the minimum value to the maximum value and back to the minimum value. The default value is 1.0 seconds, with a minimum allowable value of 0.1 seconds.

center_seconds

This parameter specifies the center point of the triangle waveform in seconds. It determines the time at which the waveform reaches its peak value. The default value is 10.0 seconds, and it can be adjusted to any floating-point number to fit your specific timing requirements.

Triangle Event Curve [Dream] Output Parameters:

FLOAT

This output represents the current value of the triangle waveform at the given time. It is a floating-point number that varies between the specified min_value and max_value based on the current time and the defined waveform parameters.

INT

This output is the integer representation of the current value of the triangle waveform. It is derived by rounding the FLOAT output to the nearest integer, providing a discrete value that can be used in scenarios where integer values are required.

Triangle Event Curve [Dream] Usage Tips:

• To create a smooth pulsing effect, set the width_seconds to a value that matches the desired pulse duration and adjust the center_seconds to control the timing of the peak.
• Use the max_value and min_value parameters to define the amplitude of the waveform, ensuring that the values fit within the range required for your specific animation.

Triangle Event Curve [Dream] Common Errors and Solutions:

"Invalid width_seconds value"

• Explanation: The width_seconds parameter is set to a value less than the minimum allowed (0.1 seconds).
• Solution: Ensure that the width_seconds parameter is set to a value of 0.1 seconds or greater.

"Invalid center_seconds value"

• Explanation: The center_seconds parameter is set to a negative value.
• Solution: Ensure that the center_seconds parameter is set to a non-negative value.

"Invalid max_value or min_value"

• Explanation: The max_value or min_value parameters are set to non-numeric values.
• Solution: Ensure that both max_value and min_value parameters are set to valid floating-point numbers.
