ComfyUI Node: Set Widget Value

Set Widget Value:

The ImpactSetWidgetValue node is designed to dynamically update the values of widgets within a node-based workflow. This node is particularly useful for AI artists who need to automate the adjustment of widget parameters based on specific conditions or inputs. By leveraging this node, you can ensure that your workflow remains flexible and responsive to changes, thereby enhancing the efficiency and effectiveness of your creative process. The primary function of this node is to send updated widget values to the PromptServer, which then synchronizes these changes across the workflow. This capability allows for real-time updates and adjustments, making it easier to experiment with different settings and achieve the desired artistic outcomes.

Set Widget Value Input Parameters:

signal

The signal parameter is used to trigger the execution of the node. It acts as an initiator for the process of updating widget values. This parameter does not have a specific value range or default value, as it is typically a boolean or event-based trigger.

node_id

The node_id parameter specifies the unique identifier of the node whose widget values are to be updated. This ID is crucial for targeting the correct node within the workflow. It is a string value that must match the ID of an existing node in the workflow.

widget_name

The widget_name parameter indicates the name of the widget within the specified node that needs to be updated. This is a string value that should correspond to the exact name of the widget as defined in the node's configuration.

boolean_value

The boolean_value parameter allows you to set a boolean value (True or False) for the specified widget. This parameter is optional and should be used when the widget expects a boolean input.

int_value

The int_value parameter allows you to set an integer value for the specified widget. This parameter is optional and should be used when the widget expects an integer input.

float_value

The float_value parameter allows you to set a floating-point value for the specified widget. This parameter is optional and should be used when the widget expects a float input.

string_value

The string_value parameter allows you to set a string value for the specified widget. This parameter is optional and should be used when the widget expects a string input.

Set Widget Value Output Parameters:

signal

The signal output parameter returns the same signal that was used to trigger the node. This allows for chaining multiple nodes together, ensuring that the workflow continues to execute smoothly after the widget values have been updated.

Set Widget Value Usage Tips:

• Ensure that the node_id and widget_name parameters are correctly specified to avoid updating the wrong widget.
• Use the appropriate value type (boolean, int, float, string) based on the expected input of the widget to prevent errors.
• Utilize the signal parameter to chain multiple nodes and create complex, dynamic workflows.

Set Widget Value Common Errors and Solutions:

Invalid node_id or widget_name

• Explanation: The specified node_id or widget_name does not match any existing node or widget in the workflow.
• Solution: Double-check the node_id and widget_name to ensure they are correctly specified and correspond to existing elements in the workflow.

Incorrect value type

• Explanation: The value provided does not match the expected type for the widget (e.g., providing a string value for a widget that expects an integer).
• Solution: Verify the expected input type for the widget and provide a value that matches this type.

Missing signal parameter

• Explanation: The signal parameter is not provided, preventing the node from being triggered.
• Solution: Ensure that the signal parameter is included and correctly configured to initiate the node's execution.
