Scratch 2.0 was a completely Flash-based program, in which both the project editor and project page viewer used the same player, the Flash player. The Flash player was first introduced during the Scratch 1.x website as an alternative to the Java Player.
History
- On Tuesday, February 22, 2011, an announcement was made about the new player.[1] It asked for feedback and bug reports. Within an hour, there were more than 20 replies, many of them giving much praise to the new player.
- On Thursday, October 18, 2012, an announcement was made about the Flash player becoming the default, even for non-registered users.[2]
- On Saturday, May 9, 2013, the Flash player exited its beta stage with the final release of Scratch 2.0, and became the official, only player available on the Scratch website.
- On Wednesday, January 2, 2019, the Flash player was entirely replaced with the release of Scratch 3.0 which runs with HTML5 and JavaScript.
- Support for Adobe Flash Player ended on December 31, 2020.[3] The Scratch 2.0 offline editor, which uses Adobe AIR, may still be downloaded and used, however.
Changes
There were several noticeable changes from the Java player. Some of these included:
- Scratch 2.0 styling
- An enlarged screen mode that adjusted to one's web browser's size
- Text in variables and lists were vector text
- Variables and lists were displayed differently
- The "ask" box showed a cursor
- A new Flash loading bar
- Shift-clicking the Green Flag would switch the project to Turbo Mode; shift-clicking the flag again will put the project back into regular mode. Turbo mode can be helpful for performing complicated computations rapidly
- Supported some blocks that would appear in Scratch 2.0[4]
- Scratch projects could be opened from local files by shift-clicking the version number
Full Screen
- This article is about the version in Scratch 2.0. For the feature in Scratch 1.4, see Presentation Mode.
There was a full screen option in the Flash Player. If the browser is put into full screen mode, then Scratch is put into full screen. Full screen is very similar to presentation mode, except presentation mode doubled the stage's vertical and horizontal resolution, and full screen mode scales and fits to one's browser's displaying size.
When the 
button is clicked, it goes into full screen, which almost fits the computer's resolution, through displaying tools; and when the 
button is clicked, the resolution adjusts back to normal size.
Bitmap graphics may look pixelated in full screen mode.
Crashing
If the Flash Player runs something which causes too much lag, the Adobe Flash Player will crash. The user can reload the Flash Player by reloading the page. On certain browsers, there's an option to send a crash report. However, this isn't necessary.
In Internet Explorer, when the Flash Player crashes, it leads to a white screen with a circle containing an exclamation mark. On Firefox, it shows a sad plugin, as seen on the image on the right. On Google Chrome, it crashes to a black screen with a dead puzzle piece.
