block checks if the sprite touches the mouse-pointer, another sprite
                     or the edge. If the answer is true, then it executes the blocks given after it in the condition.

                     If false, then it executes other blocks as per the given condition.
                                     block checks if the sprite is touching the color chosen in the block. If true,
                     then it executes a set of blocks, else executes another set of blocks.

                                           The  block  checks  if  the  first  chosen  colour  is  touching  the  second
                     chosen  colour.  If  true,  then  it  executes  a  set  of  blocks,  else  executes  another  set  of
                     blocks.
                                         block checks if the chosen key is pressed by the user. If true, then it
                     executes a set of blocks, else executes another set of blocks.

                    Let us create a small script to understand the working of sensing blocks.

                  Sensing an Input
                  To add sensing blocks to the script, follow the given steps:











                    1  Click on the
                   Sensing  block
                   category     in
                                                                                              2  Insert a sprite,
                   Tabs.
                                                                                             Penguin2  on  the
                                                                                             stage. Delete the
                                                                                             cat sprite.



                                4  Now drag the ask block to the script area.

                                                                                     on the tick button or press
                                                                                     the Enter key.



                                                                                     3  Add a new backdrop to
                                                                                     the stage, Arctic.
