Summary

Extracts touch data for a specific touch ID from a multi-touch input.

Description

The Touch Data For ID component filters a multi-touch input and outputs the data related only to the configured ID. This allows applications to reliably track a single finger or touch point across frames, even when multiple touches are present.

Typical use cases include gesture recognition, tracking a primary finger for dragging, or assigning specific functions to different touch IDs.
