Video Blocks

There are 3 blocks related to video sensing.

Turn Video ()

turn video [on v]

This block can be accessed only by the Stage, in the Looks palette. It can turn the video on, off, or on-flipped (flipped horizontally).

Set Video Transparency to ()%

set video transparency to (50)%

This block, like Turn Video (), can only be accessed by the Stage, in the Looks palette. It can set the transparency of the webcam output. Setting it to 0 makes it completely opaque, and setting it to 100 makes it completely transparent.

Video () on ()

(video [motion v] on [this sprite v])

This Reporter block can be accessed and used by any sprite, or the Stage. The first dropdown menu has options "motion" and "direction". The second contains a list of all the sprites.
