Motion Block
Blocks are the codes or commands used to create a program in Scratch. It looks like a puzzle
piece and each block connects with the other block to perform a task. The blocks that are
used to control the movement of a Sprite are known as Motion blocks. These are blue in
colour. Some of the commonly used motion blocks are:
move 10 steps block lets the Sprite move forward (in the direction it is facing) the number
of steps given in the text box in the block. When we write the value with a minus (–) sign, the
Sprite moves backward, e.g., move – 10 steps move -10 steps .
turn 15 degrees block lets the Sprite turn in clockwise direction by the given degrees and
turn 15 degrees block turns Sprite in anti-clockwise direction by the given degrees.
To make the Sprite jump to a new position on the stage, use go to x: 0 y: 0 block. This
block gives the x and y position of the Sprite on the stage.
Use go to mouse-pointer to tell the Sprite to follow one of the two given options: the
mouse-pointer or a random position.
