ComfyUI Node: Queue Trigger

Queue Trigger:

The ImpactQueueTrigger node is designed to manage and control the flow of signals within your AI art generation workflow. Its primary function is to trigger the addition of a signal to a queue based on a specified condition. This node is particularly useful for coordinating complex processes where certain actions need to be queued and executed in a specific order. By leveraging this node, you can ensure that your workflow remains organized and that tasks are executed in a controlled manner, enhancing the overall efficiency and reliability of your AI art generation process.

Queue Trigger Input Parameters:

signal

The signal parameter accepts any type of input signal. This signal is the primary data that will be processed and potentially queued by the node. The type of the signal can vary, allowing for flexibility in the kinds of data that can be managed by this node.

mode

The mode parameter is a boolean that determines whether the node should trigger the addition of the signal to the queue. When set to True, the node will trigger the queue addition; when set to False, it will not. The default value is True, with the label "Trigger" indicating the active state and "Don't trigger" indicating the inactive state. This parameter allows you to control the node's behavior dynamically based on the conditions of your workflow.

Queue Trigger Output Parameters:

signal_opt

The signal_opt output parameter returns the original input signal. This ensures that the signal continues to propagate through the workflow, allowing subsequent nodes to process it as needed. The output is essentially a pass-through of the input signal, maintaining the integrity and continuity of the data flow.

Queue Trigger Usage Tips:

• Use the mode parameter to dynamically control when the signal should be added to the queue. This can be particularly useful in conditional workflows where certain actions should only be triggered under specific circumstances.
• Combine the ImpactQueueTrigger node with other logic nodes to create complex, conditional workflows that can handle a variety of scenarios and ensure that tasks are executed in the desired order.

Queue Trigger Common Errors and Solutions:

"Failed to send sync message"

• Explanation: This error occurs when the node is unable to communicate with the PromptServer to send the "impact-add-queue" message.
• Solution: Ensure that the PromptServer is running and accessible. Check your network connection and verify that there are no firewall rules blocking the communication.

"Invalid signal type"

• Explanation: This error occurs when the input signal is of an unsupported type.
• Solution: Verify that the input signal is of a type that the node can process. Refer to the documentation for supported signal types and ensure that your input matches one of these types.
