Type Stack
Introduced in 2.0

The Turn Video () block is a Sensing block and a stack block. It can turn the webcam on, off, or on flipped horizontally, depending on the argument. Early in the Scratch 2.0 alpha, it was categorized as a Looks block.

Caution (2).png Caution: This block can turn on the computer's webcam. If you are uncomfortable with using a webcam for safety, avoid usage of this block or click "Deny" on the Adobe Flash Player warning if one pops up.

Options

The block contains a drop-down list of three options.

  • On — Turns the webcam on for utilization of the motion-sensing features in Scratch 2.0.
  • Off — Turns the webcam off which will cause the constant film pasted onto the Stage to remove.
  • On-flipped — Turns the webcam on but displays the video footage in a horizontally flipped form. This option is not available in the stage but only in sprites.

Example Uses
