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.
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. |
