Face Sensing
The Face Sensing extension detects a face in your webcam and reports where its features are, so a sprite can follow your nose, sit on your head, or react when you tilt. It is a remote extension, not bundled with the editor.
Load it from Add Extension and choose Face Sensing.
Loaded remotely, needs a camera
Face Sensing is not bundled with the editor. The first time you load it, RemixWarp downloads it from a remote URL, so you need an internet connection to load it (once loaded and saved, it reloads with the project). Like Video Sensing, it needs webcam permission to run.
Blocks
The extension provides blocks in a few groups:
- Face detection: a hat that runs when a face is detected, and a boolean a face is detected? so you can check for a face anywhere in your scripts.
- Face size: a face size reporter for how large the detected face is, plus a command to set the sprite's size to match the face.
- Face tilt: a face tilt reporter, a hat that runs when the face tilts left or right, and a command to point the sprite in the direction of the tilt.
- Feature positions: reporters for the position of face parts, including between the eyes, each eye, the nose, the mouth, each ear, and the top of the head, plus a go to command to move a sprite to any of those parts.
The exact block wording comes from the extension itself; open it in the editor to see the full list.
Tips
- Only one face is tracked at a time, so this works best with a single person facing the camera in reasonable light.
- Pair go to a face part with a sprite costume to make hats, glasses, or masks that follow your face.
- If detection fails to start, it is usually a camera-permission or lighting problem, not a project bug.
