Experimental blocks were blocks that did not work well and therefore did not appear in the Block Palette. They were available from Scratch 1.0 through 1.2. In 1.0, they were accessed by shift-clicking the Extras menu and choosing "show experimental blocks"; in 1.1 and 1.2, through Shift-Click-R. They are similar to the Motor Blocks, which are also not displayed by default; however, the Motor blocks are fully functional.

Sound Blocks

The 13 experimental Sound blocks.

There were 13 experimental Sound Blocks. All were Stack-shaped. They were:

  • Start movie
  • Stop movie
  • Change seconds by ()
  • Set seconds to ()
  • Change zoom by ()
  • Set zoom to ()%
  • Change horiz. pan by ()
  • Set horiz. pan to ()
  • Change vert. pan by ()
  • Set vert. pan to ()
  • Change fade by ()
  • Set fade to ()%
  • Set fade color to []

The fade blocks were later changed to say "trans." (short for "transparent")[problematic].

These blocks were likely for use with the Scratch MoviePlayerMorph.

Sensing Blocks

The 9 experimental Sensing blocks

There were 9 experimental Sensing Blocks. 6 were Reporter Blocks, and 3 were Stacks. They were:

  • Camera motion
  • Camera direction
  • Camera relative x
  • Camera relative y
  • Camera absolute x
  • Camera absolute y
The readouts of the reporter blocks, all showing "a ScratchSpriteMorph()".
  • Track motion
  • Track color
  • Auto calibrate red

These blocks appear to be intended for camera sensing, but in all version of Scratch include them, they do not work and their stage monitors simply display "a ScratchSpriteMorph()". True camera support was later added in Scratch 2.0.

Experimental Blocks in 2.0

Recently, experimental blocks available in Scratch 2.0 are left over but still can be used. These blocks include For Each () in (), While (), Incr Counter, Clear Counter, and Counter (currently called "noop").[1]
