ComfyUI Node: 🔄 Auto Switch

🔄 Auto Switch:

The SDVN AutoSwitch node is designed to streamline decision-making processes within your creative workflows by automatically selecting the first available input from a set of optional inputs. This node is particularly useful when you have multiple potential data sources or options and want to ensure that the workflow continues smoothly without manual intervention. By evaluating each input in sequence, the AutoSwitch node identifies and returns the first non-null input, thereby optimizing the flow and reducing the need for complex conditional logic. This capability is beneficial in scenarios where you want to prioritize inputs or handle fallback options seamlessly, enhancing the efficiency and reliability of your creative projects.

🔄 Auto Switch Input Parameters:

input1

This parameter represents the first optional input that the AutoSwitch node will evaluate. It can accept any data type, and if it is not null, it will be selected as the output. There are no specific minimum, maximum, or default values for this parameter, as it is entirely dependent on the data you provide.

input2

Similar to input1, this parameter is the second optional input. If input1 is null, the node will evaluate input2 next. It also accepts any data type and does not have predefined limits or default values.

input3

This is the third optional input parameter. The node will check this input if both input1 and input2 are null. It functions in the same way as the previous inputs, with no specific constraints.

input4

The fourth optional input parameter, input4, is evaluated if the preceding inputs are null. It accepts any data type and follows the same rules as the other inputs.

input5

This parameter is the fifth in the sequence of optional inputs. It will be considered if all previous inputs are null, maintaining the same flexibility in data type and value constraints.

input6

The final optional input parameter, input6, is evaluated last. If all other inputs are null, this input will be checked. Like the others, it accepts any data type and has no specific limitations.

🔄 Auto Switch Output Parameters:

output

The output parameter of the AutoSwitch node is the first non-null input from the provided optional inputs. If all inputs are null, the output will be null as well. This output is crucial as it determines the data that will be passed on to subsequent nodes in your workflow, ensuring that the process continues with the most relevant available data.

🔄 Auto Switch Usage Tips:

• Use the AutoSwitch node when you have multiple potential data sources and want to ensure that your workflow continues with the first available data without manual checks.
• Arrange your inputs in order of priority, placing the most preferred data source first to ensure it is selected if available.
• Consider using the AutoSwitch node in conjunction with other nodes that may produce optional outputs, allowing for a more dynamic and adaptable workflow.

🔄 Auto Switch Common Errors and Solutions:

All inputs are null

• Explanation: This error occurs when all provided inputs to the AutoSwitch node are null, resulting in a null output.
• Solution: Ensure that at least one of the inputs is populated with valid data. Check upstream nodes to verify that they are producing the expected outputs.

Unexpected data type

• Explanation: The node may encounter issues if the inputs are not of a compatible data type for subsequent nodes.
• Solution: Verify that the data types of the inputs are consistent with the requirements of downstream nodes. Use type conversion nodes if necessary to ensure compatibility.
