Glossary of basic Scratch 2.0 blocks
Scratch is a scripting, visual programming language. We use it to build scripts by putting together blocks representing commands, control instructions, expressions, etc. The version 2.0 set of blocks is divided into 10 categories (there were 8 categories in version 1.4), blocks in each category are distinguished by a different colour. This glossary is not a description of all the blocks, only the most important ones as well as those used in scenarios of classes designed for students in grades four to six of primary schools developed as part of the “Masters of Coding” project. Version 2.0 introduces a very important More blocks category which allows users to define their own blocks. It is not described in this document, because the first eight scenarios do not expect users to create their own blocks. This category will be described in future scenarios. Each sprite and stage may have their own scripts. The set of blocks from which you can build scripts for a stage is slightly different than that used for sprites, for example the category Motion for the stage is empty, because the stage cannot be moved or rotated. First, we will discuss various types of blocks for sprites, and then basic information about blocks available for the stage will be provided.
The category Motion groups sprite movement blocks, used for their movement, rotation and reading current data related to a sprite’s location. These are very often used basic blocks. Below is a description of all the blocks in this category.
Moves the sprite by a certain distance in accordance with the current direction and current pen settings (applied/raised, colour, thickness). The default value can be edited. If we want to move the sprite back, we must enter a negative value.
Example:
Rotates the sprite right (clockwise) by a specified degree. The default value can be edited.
Example:
