Bool Description

Manage boolean values for logical operations in AI art workflows efficiently.


The Bool-🔬 node is designed to handle boolean values within your AI art workflows. This node is essential for logical operations, allowing you to manage and manipulate boolean data effectively. By providing a straightforward mechanism to work with boolean values, it simplifies the process of integrating logical conditions and decisions into your creative projects. Whether you need to set a flag, toggle a state, or control the flow of your logic, the Bool-🔬 node offers a reliable and easy-to-use solution.

Bool Input Parameters:


The value parameter is a boolean input that determines the state of the Bool-🔬 node. It accepts a boolean value (True or False), with the default being False. This parameter is crucial as it directly influences the output of the node, allowing you to set or change the boolean state as needed in your workflow.

Bool Output Parameters:


The BOOLEAN output parameter returns the boolean value that was input into the node. This output is essential for passing the boolean state to subsequent nodes in your workflow, enabling further logical operations or decisions based on the boolean value.

Bool Usage Tips:

  • Use the Bool-🔬 node to set initial conditions or flags in your workflow, which can then be used to control the flow of logic.
  • Combine the Bool-🔬 node with other logical nodes, such as Compare-🔬 or If ANY return A else B-🔬, to create complex decision-making processes.
  • Utilize the default value feature to ensure that your workflow has a predictable starting state.

Bool Common Errors and Solutions:

Invalid boolean value

  • Explanation: The input provided is not a valid boolean value.
  • Solution: Ensure that the input is either True or False.

Missing input value

  • Explanation: The value parameter is required but not provided.
  • Solution: Provide a boolean value (True or False) for the value parameter to ensure the node functions correctly.
