Eng:Scratch 1.0

Scratch 1.0, released on January 8, 2007, was the first version of Scratch released to the public.

Features
As this was the first public version of Scratch, there were no previous versions to compare it to. It can be compared to Scratch 1.4, however. One notable difference is the lack of cap blocks. All cap blocks in Scratch 1.4 were stack blocks in 1.0.

Some features include:

Blocks
A total of 95 blocks in 5 shapes were in Scratch 1.0. Blocks could be activated by double-clicking. Comments did not exist in this release.
 * Motion: 16 (13 stack, 3 reporter)
 * Looks: 16 (15 stack, 1 reporter)
 * Sound: 6 (all stack)
 * Pen: 11 (all stack)
 * Control: 15 (4 hat, 6 stack, 5 C)
 * Sensing: 14 (1 stack, 6 reporter, 7 boolean)
 * Numbers: 14 (8 reporter, 6 boolean)
 * Variables: 3 for each variable (2 stack, 1 reporter)

Experimental Blocks
Scratch 1.0 through 1.2 had some experimental blocks that could be accessed by shift-clicking the "extras" menu (the 1.0 equivalent of Shift-Click-R) and choosing "show experimental blocks".

The Sound palette had some blocks to work with the ScratchMoviePlayerMorph. These were: start movie, stop movie; change seconds by (1), set seconds to (0); change zoom by (10), set zoom to (100)%; change horiz. pan by (10), set horiz. pan to (0), change vert. pan by (10), set vert. pan to (0); change fade by (-10), set fade to (100)%, set fade color to []

The Sensing palette included some camera interaction blocks. All the reporters simply showed "a ScratchSpriteMorph". Camera support has been added in Scratch 2.0. They were: camera motion, camera direction, camera relative x, camera relative y, camera absolute x, camera absolute y, track motion, track color, auto calibrate red

UI
The Scratch 1.0 user interface looked remarkably similar to the 1.4 interface; however, it did have some differences
 * There was only one menu. Some features were shown as buttons, while others were lumped into the "extras" menu. There was also an icon for the project notes on the right. The extras menu contained:
 * about
 * set blocks language
 * start single stepping
 * import sprite
 * import project
 * compress sounds
 * compress images
 * The Green Flag and Stop Sign are much larger.
 * There is a button to create a new Scratch Cat (the default sprite) with the other methods of creating a new sprite
 * Sprite thumbnails (including the Stage's) show the thumbnail, name, amount of costumes, and amount of scripts. The Stage's background count only shows with two or more backgrounds.
 * No Draggable Sprite Feature
 * Costume/sound delete button is a button instead of an "x" icon.

Variants
There are two known variants of Scratch 1.0: 1.0.1 and 1.0.2.

1.0.1 was never released; only internal builds are available. A build from January 24, 2007 can be downloaded here. Net Scratch was based on this version.

1.0.2 was also not officially released. A build from sometime in 2007, most likely February–March is available here.
