ComfyUI Node: #️⃣ Logic Switch

#️⃣ Logic Switch:

The SDVN Logic node is designed to facilitate decision-making processes within your AI art projects by evaluating logical conditions between two inputs. This node allows you to compare two values using a variety of logical operators, such as equality, inequality, and membership, among others. By doing so, it enables you to dynamically control the flow of your creative pipeline based on specific conditions. The primary benefit of this node is its ability to automate decision-making, which can significantly enhance the efficiency and flexibility of your workflow. Whether you are comparing numerical values, checking for the presence of an item in a list, or evaluating complex conditions, the SDVN Logic node provides a robust solution for integrating logic-based operations into your artistic endeavors.

#️⃣ Logic Switch Input Parameters:

input_true

This parameter represents the output value that will be returned if the specified logical condition evaluates to true. It can be any data type, allowing you to customize the output based on your specific needs. The flexibility of this parameter ensures that you can tailor the node's behavior to suit a wide range of scenarios.

input_false

This parameter is the counterpart to input_true and represents the output value that will be returned if the logical condition evaluates to false. Like input_true, it can be any data type, providing you with the ability to define alternative outcomes when the condition is not met.

a

This parameter is one of the two values to be compared in the logical operation. It can be of any data type, allowing for versatile comparisons. The value of a plays a crucial role in determining the outcome of the logical evaluation.

b

Similar to a, this parameter is the second value involved in the logical comparison. It can also be of any data type, and its value is essential for the logical operation to be performed accurately.

logic

This parameter specifies the logical operation to be performed between a and b. It offers a range of options, including "a = b", "a != b", "a > b", "a < b", "a >= b", "a <= b", "a in b", and "a not in b". Each option represents a different type of comparison, allowing you to choose the most appropriate logic for your specific use case.

#️⃣ Logic Switch Output Parameters:

output

The output parameter is the result of the logical evaluation. It returns either the input_true or input_false value based on whether the specified logical condition is met. This output is crucial for directing the flow of your project, enabling you to implement conditional logic effectively.

#️⃣ Logic Switch Usage Tips:

• Use the SDVN Logic node to automate decision-making processes in your creative projects, allowing for dynamic adjustments based on specific conditions.
• Experiment with different logical operations to find the most suitable comparison for your needs, ensuring that the node's behavior aligns with your artistic goals.
• Consider using the node in conjunction with other nodes to create complex logic chains that enhance the interactivity and responsiveness of your workflow.

#️⃣ Logic Switch Common Errors and Solutions:

Invalid Logic Operation

• Explanation: This error occurs when an unsupported logical operation is specified in the logic parameter.
• Solution: Ensure that the logic parameter is set to one of the supported operations: "a = b", "a != b", "a > b", "a < b", "a >= b", "a <= b", "a in b", or "a not in b".

Type Mismatch

• Explanation: This error arises when the values of a and b are of incompatible types for the specified logical operation.
• Solution: Verify that the data types of a and b are compatible with the chosen logical operation. For example, ensure that numerical comparisons are performed on numerical values.

Missing Input Values

• Explanation: This error occurs when one or more required input parameters are not provided.
• Solution: Check that all necessary input parameters (input_true, input_false, a, b, and logic) are correctly specified and not left empty.
