Sequential Number Generator

The Sequential Number Generator is a utility node that generates sequential integer numbers within a defined range. It's designed to work with ComfyUI's seed system, allowing for controlled sequential number generation that can be used in various workflows.

Parameters

Required Parameters

1. start (INT)

   • The starting value of the sequence range
   • Default value: 0
   • Minimum value: -2147483648
   • Maximum value: 2147483647

2. end (INT)

   • The ending value of the sequence range
   • Default value: 1
   • Minimum value: -2147483648
   • Maximum value: 2147483647

3. seed (INT)

   • The seed value that determines the current position in the sequence
   • Default value: 0
   • Minimum value: 0
   • Maximum value: 18446744073709551615 (0xffffffffffffffff)

Outputs

The node returns two values:

1. value: The current number in the sequence
2. next: The next number that will be generated in the sequence

Usage

1. Set the desired range using the start and end parameters
2. Provide a seed value to determine the current position in the sequence
3. The node will output both the current value and the next value in the sequence

Examples

Basic Counter

• start: 0
• end: 9
• seed: 0

Result:

• value: 0
• next: 1

Custom Range

• start: 100
• end: 105
• seed: 2

Result:

• value: 102
• next: 103

Notes

• The sequence wraps around when it reaches the end value
  • For example, with range 1-3:
    • If current value is 3, next value will be 1
• The start value must be less than or equal to the end value
• The seed value maps to a position within the specified range
• The sequence is deterministic based on the seed value
• Useful for:
  • Creating numbered sequences
  • Implementing counters
  • Generating sequential batch numbers
  • Cycling through a range of values
