If

Documentation

• Class name: If ANY execute A else B
• Category: Logic
• Output node: False

This node conditionally executes one of two possible outputs based on a boolean input. It serves as a logical branch, allowing for dynamic flow control within a node-based execution environment.

Input types

Required

• ANY
  • A boolean input that determines which of the two possible outputs to execute. Its value dictates the flow of execution, enabling conditional logic within the node's operation.
  • Comfy dtype: *
  • Python dtype: bool
• IF_TRUE
  • The output to be executed if the ANY input is True. This parameter represents the action taken when the condition is met.
  • Comfy dtype: *
  • Python dtype: Any
• IF_FALSE
  • The output to be executed if the ANY input is False. This parameter represents the alternative action taken when the condition is not met.
  • Comfy dtype: *
  • Python dtype: Any

Output types

• ?
  • Comfy dtype: *
  • The result of executing either IF_TRUE or IF_FALSE, depending on the evaluation of ANY. The exact nature of this output is dynamic, reflecting the conditional execution logic of the node.
  • Python dtype: Any

Usage tips

• Infra type: CPU
• Common nodes: unknown
