ComfyUI Node: 1 Bool from List

1 Bool from List:

The BooleanListInterpreter1 node is designed to decode a single Boolean value from a list of Boolean values. This node is particularly useful when you need to extract specific Boolean values from a list based on a starting index. It simplifies the process of handling Boolean lists by allowing you to specify an index from which to start the extraction. If the specified starting index exceeds the length of the Boolean list, the node will automatically restart from the beginning of the list, ensuring that a valid Boolean value is always returned. This functionality is essential for scenarios where Boolean values need to be dynamically accessed and utilized in various logical operations or conditions.

1 Bool from List Input Parameters:

bool_list

The bool_list parameter is a list of Boolean values from which the node will extract a single Boolean value. This list serves as the source of Boolean values that the node will process. The bool_list parameter is essential for the node's operation, as it provides the data that will be interpreted based on the specified starting index.

Start_At_Index

The Start_At_Index parameter specifies the index in the bool_list from which the node will begin extracting the Boolean value. If the Start_At_Index is greater than the length of the bool_list, the node will restart from index 0. This parameter ensures flexibility in accessing different parts of the Boolean list. The default value is 0, the minimum value is 0, and the step value is 1.

1 Bool from List Output Parameters:

bool

The bool output parameter is the single Boolean value extracted from the bool_list based on the specified Start_At_Index. This output represents the interpreted Boolean value that can be used in subsequent logical operations or conditions. The node ensures that a valid Boolean value is always returned, even if the starting index exceeds the length of the list.

1 Bool from List Usage Tips:

• To effectively use the BooleanListInterpreter1 node, ensure that the bool_list parameter is populated with the Boolean values you need to interpret.
• Adjust the Start_At_Index parameter to target specific Boolean values within the list, especially if you need to cycle through the list dynamically.

1 Bool from List Common Errors and Solutions:

"IndexError: list index out of range"

• Explanation: This error occurs if the Start_At_Index is greater than the length of the bool_list and the node fails to handle the restart logic.
• Solution: Ensure that the Start_At_Index is within the valid range of the bool_list length or verify that the node's logic correctly handles the restart from index 0.

"TypeError: 'NoneType' object is not subscriptable"

• Explanation: This error occurs if the bool_list is not properly initialized or is set to None.
• Solution: Ensure that the bool_list parameter is correctly populated with a valid list of Boolean values before executing the node.
