GET THE VALUE BY INDEX

Retrieves a single scalar value (X or Y) from a curve at a specified integer index position. Use this worker when you need to extract a point value from a curve by its positional index rather than by an X-axis lookup.

When to use

Classification: process.

Tagged: curve, extract, get_value, index, lookup, scalar.

Inputs

Label ID Type Default Required Description
Curve To Be Looked Up curvetobelookedup vector   The input curve (X/Y vector) from which a value will be retrieved by index.
Index Number index_number scalar 0.0   Zero-based integer index of the point to retrieve from the curve; defaults to 0 (the first point).
Return Type return_type scalar y   Axis component to return at the specified index: ‘x’ for the X-coordinate or ‘y’ for the Y-coordinate; defaults to ‘y’.
Not Found Value not_found_value scalar 0.0   Fallback scalar value returned when the specified index does not exist in the curve; defaults to 0.0.

Outputs

Label ID Type Description
curve_get_value_by_index_output_1 curve_get_value_by_index_output_1 scalar Scalar X or Y value extracted from the curve at the specified index, or the not_found_value if the index is out of range.
