ComfyUI Node: Vec2UnaryCondition

Vec2UnaryCondition:

The CM_Vec2UnaryCondition node is designed to evaluate a specific condition on a 2-dimensional vector (Vec2) and return a boolean result. This node is particularly useful for AI artists who need to apply mathematical conditions to vectors in their creative workflows. By leveraging predefined unary conditions, this node simplifies the process of checking properties or states of vectors, enabling more dynamic and responsive art generation. The primary function of this node is to take a vector and an operation type as inputs, apply the specified unary condition, and output a boolean value indicating whether the condition is met.

Vec2UnaryCondition Input Parameters:

op

This parameter specifies the unary condition to be applied to the vector. It is a string that must match one of the keys in the predefined VEC_UNARY_CONDITIONS dictionary. The available options for this parameter are determined by the keys in this dictionary, which represent different unary conditions that can be checked on the vector. The choice of operation directly impacts the result of the node, as it defines the condition that will be evaluated. There are no minimum or maximum values for this parameter, but it must be one of the valid keys in the VEC_UNARY_CONDITIONS.

a

This parameter represents the 2-dimensional vector (Vec2) on which the unary condition will be applied. The vector should be provided in a format that the node can interpret, typically as a list or array of two numerical values. The values in the vector can vary widely, but they should be within the range that makes sense for the specific condition being evaluated. The default value for this parameter is DEFAULT_VEC2, which is a predefined vector that the node can use if no other vector is provided.

Vec2UnaryCondition Output Parameters:

BOOL

The output of this node is a boolean value (BOOL). This value indicates whether the specified unary condition is met for the given vector. If the condition is true, the output will be True; otherwise, it will be False. This boolean result can be used in subsequent nodes or logic to control the flow of operations, making it a crucial part of dynamic and conditional workflows in AI art generation.

Vec2UnaryCondition Usage Tips:

• Ensure that the vector provided as input (a) is in the correct format and within the expected range for the condition being evaluated.
• Familiarize yourself with the available unary conditions in the VEC_UNARY_CONDITIONS dictionary to effectively utilize this node for various checks and validations in your workflows.

Vec2UnaryCondition Common Errors and Solutions:

Invalid operation type

• Explanation: The op parameter does not match any of the keys in the VEC_UNARY_CONDITIONS dictionary.
• Solution: Verify that the op parameter is set to one of the valid keys in the VEC_UNARY_CONDITIONS dictionary.

Incorrect vector format

• Explanation: The input vector a is not in the correct format or does not contain exactly two numerical values.
• Solution: Ensure that the vector a is provided as a list or array of two numerical values.

Condition evaluation error

• Explanation: An error occurred while evaluating the unary condition on the vector.
• Solution: Check the values in the vector and the selected condition to ensure they are compatible and within the expected range for the operation.
