ComfyUI Node: Script Node

Script Node:

The 0246.ScriptNode is a versatile and powerful node designed to execute custom scripts within the ComfyUI framework. This node allows you to define and run specific functions or operations, making it highly adaptable for various tasks in your AI art projects. By leveraging the capabilities of the ScriptNode, you can automate complex workflows, manipulate data, and integrate custom logic seamlessly into your node-based environment. The primary goal of the ScriptNode is to provide a flexible and efficient way to extend the functionality of your AI art projects, enabling you to achieve more sophisticated and tailored results.

Script Node Input Parameters:

script

The script parameter is the core input for the ScriptNode, representing the custom script or function you wish to execute. This parameter is crucial as it defines the specific operations or logic that the node will perform. The script can include various functions and methods tailored to your needs, allowing for extensive customization and control over the node's behavior. There are no predefined minimum or maximum values for this parameter, as it entirely depends on the complexity and requirements of your custom script.

exec_mode

The exec_mode parameter determines the execution mode of the script. It can take values such as "act" or other modes that define how the script should be processed. This parameter impacts the flow and handling of the script execution, ensuring that the node operates in the desired manner. The default value is typically "act," but it can be adjusted based on specific needs.

pin

The pin parameter is used to pass additional data or context to the script. It acts as a dictionary containing key-value pairs that the script can utilize during execution. This parameter is essential for providing dynamic inputs and ensuring that the script has access to all necessary information. There are no strict constraints on the values, as they depend on the script's requirements.

inst

The inst parameter represents the instance data for the script execution. It includes information such as the node ID, prompt, and workflow, which are necessary for the script to function correctly. This parameter ensures that the script has the context it needs to operate within the node-based environment. The values are typically generated and managed by the framework.

Script Node Output Parameters:

result

The result parameter is the primary output of the ScriptNode, representing the outcome of the script execution. This parameter can contain various types of data, depending on the script's operations and logic. It is essential for capturing the results and ensuring that subsequent nodes or processes can utilize the output effectively. The interpretation of the result value depends on the specific script and its intended purpose.

res

The res parameter is an auxiliary output that extends the primary result. It is used to store additional data or intermediate results generated during the script execution. This parameter is crucial for complex scripts that produce multiple outputs or require further processing. The values in res are typically structured as lists or dictionaries, depending on the script's design.

Script Node Usage Tips:

• Ensure that your custom script is thoroughly tested and debugged before integrating it into the ScriptNode to avoid runtime errors.
• Utilize the pin parameter to pass dynamic inputs and context-specific data to your script, enhancing its flexibility and adaptability.
• Leverage the exec_mode parameter to control the execution flow and optimize the performance of your script for specific tasks.
• Use the res parameter to capture and manage intermediate results, enabling more complex and multi-step operations within your script.

Script Node Common Errors and Solutions:

Node class does not have any required input.

• Explanation: This error occurs when the node class specified in the script does not define any required input parameters.
• Solution: Ensure that the node class includes at least one required input parameter. Review the class definition and add the necessary inputs.

Node class does not have any output.

• Explanation: This error indicates that the node class specified in the script does not define any output parameters.
• Solution: Verify that the node class includes at least one output parameter. Update the class definition to include the required outputs.

pin_direct is not supported yet.

• Explanation: This error occurs when the pin_direct mode is selected, which is not currently supported by the ScriptNode.
• Solution: Choose a different pin mode, such as pin_highway or pin_junction, to ensure compatibility with the ScriptNode.

Script rule loop mode is not supported yet.

• Explanation: This error indicates that the specified script rule loop mode is not recognized or supported by the ScriptNode.
• Solution: Use a supported loop mode, such as "cycle" or "slice," to ensure proper script execution. Review the available loop modes and select an appropriate one.
