The stage is 360 pixels tall and 480 pixels wide.
SPRITE’S DIRECTION
In Scratch, a sprite’s direction refers to the angle at which the sprite is facing on the stage. This
direction is measured in degrees, with 0 degrees pointing upwards, 90 degrees pointing to the
right, 180 degrees pointing downwards, and 270 degrees pointing to the left menu.
You can adjust the direction of a sprite using the Turn block found in the Motion blocks pallete.
The block allows you to rotate the sprite clockwise by a specified number of degrees.
Alternatively, you can use the block to rotate the sprite anticlockwise, depending
on your needs. The number of degrees specified in the Turn block can be customised to fit the
requirements of your project. For example, if you set the block to turn by 15 degrees, the sprite
will rotate 15 degrees in the chosen direction.

UNDERSTANDING BLOCKS
Blocks in Scratch resemble puzzle pieces and are used to give instructions to the computer.
When combined, these interconnected blocks form what is known as a script, which constitutes
the code in Scratch. Each script represents a sequence of commands that Scratch executes from
top to bottom when you double-click on it.
To use a block, simply select it from the Blocks Palette and drag it into the Scripts Pane where
you build your script. If you need to remove a block, drag it away from the Scripts Pane and it
will be discarded. This intuitive drag-and-drop interface makes it easy to create and modify your
code by visually arranging blocks to define how your sprite should behave and interact.
