ComfyUI Node: Queue Trigger (Countdown)

Queue Trigger (Countdown):

The ImpactQueueTriggerCountdown node is designed to manage and control the execution flow within a node-based system by implementing a countdown mechanism. This node is particularly useful for scenarios where you need to trigger actions after a specific number of iterations or events. It helps in synchronizing processes and ensuring that certain tasks are executed only after a predefined count is reached. The node operates by incrementing a counter each time it is executed and triggers an action when the counter reaches a specified total. This functionality is essential for creating complex workflows that require precise control over the sequence of operations.

Queue Trigger (Countdown) Input Parameters:

count

The count parameter represents the current count value. It is an integer that starts from a default value of 0 and increments with each execution of the node. The minimum value for this parameter is 0, and the maximum value is 0xffffffffffffffff. This parameter is crucial for tracking the number of times the node has been executed.

total

The total parameter specifies the total count value at which the node will trigger an action. It is an integer with a default value of 10, a minimum value of 1, and a maximum value of 0xffffffffffffffff. This parameter determines the threshold for triggering the action, making it essential for controlling the timing of the node's execution.

mode

The mode parameter is a boolean that controls whether the node should trigger an action or not. It has a default value of True, with the options labeled as "Trigger" for True and "Don't trigger" for False. This parameter allows you to enable or disable the triggering mechanism, providing flexibility in managing the node's behavior.

signal (optional)

The signal parameter is an optional input that can be of any type. It is used to pass additional data or signals through the node. This parameter is useful for integrating the node into more complex workflows where additional information needs to be propagated.

unique_id (hidden)

The unique_id parameter is a hidden input that uniquely identifies the node instance. It is used internally to manage the node's state and interactions with other nodes. This parameter ensures that each node instance operates independently and maintains its own state.

Queue Trigger (Countdown) Output Parameters:

signal_opt

The signal_opt output parameter returns the value of the signal input parameter. This allows the node to pass through any additional data or signals that were provided as input, ensuring that the workflow can continue with the necessary information.

count

The count output parameter returns the current count value after the node has been executed. This allows you to track the progress of the countdown and use the count value in subsequent nodes or operations.

total

The total output parameter returns the total count value specified in the input. This provides context for the countdown mechanism and allows you to reference the threshold value in other parts of the workflow.

Queue Trigger (Countdown) Usage Tips:

• Use the total parameter to set the desired number of iterations or events before triggering an action. This is useful for creating delays or synchronizing tasks in your workflow.
• Enable or disable the triggering mechanism using the mode parameter. This allows you to control whether the node should trigger an action based on specific conditions or states in your workflow.

Queue Trigger (Countdown) Common Errors and Solutions:

"Invalid count value"

• Explanation: The count parameter has an invalid value, possibly outside the allowed range.
• Solution: Ensure that the count value is within the range of 0 to 0xffffffffffffffff.

"Invalid total value"

• Explanation: The total parameter has an invalid value, possibly outside the allowed range.
• Solution: Ensure that the total value is within the range of 1 to 0xffffffffffffffff.

"Mode parameter not set"

• Explanation: The mode parameter is not set correctly.
• Solution: Ensure that the mode parameter is set to either True (Trigger) or False (Don't trigger).

"Signal parameter missing"

• Explanation: The optional signal parameter is missing when it is required for the workflow.
• Solution: Provide a valid signal input if your workflow depends on additional data or signals being passed through the node.
