Motion Blocks
The blocks that are used to control the movement of a Sprite are known as Motion Blocks.
They are blue in colour. For example, the motion block is used to move a sprite.
Here, 10 is the number of steps that the sprite will move forward. You can change the
number of steps. To make the sprite move backward, give a minus (–) sign before the
number as shown below . This will move the sprite 30 steps back on the stage.
Looks Blocks
The blocks that are used to add speech and thought bubbles to the sprite are called Looks
Blocks. They are purple in colour.
For example, you want to add a speech bubble to the sprite for 2 seconds with a message
‘Hello!’ as shown .
You can change the message by clicking on the message text box and typing your own message.
You can also change the time by clicking on the time text box .
Events Blocks
This is the topmost block. It helps to run the script on the stage as it
controls the starting of scripts. It gives you the control of all the blocks
as without an event block no program will run.
To run the script, you have to click on the Go button before the other blocks.
