                       ▶  Events  block  controls  how the  blocks  in a  script  will start  to  run, if a  particular  action  is
                         done.

                       ▶  Local variables can only be accessed or modified from the sprite where they were created.

                       ▶  Sensing blocks are colour-coded light-blue, and are used to control the movement of the sprite in a
                         better manner.
