                       then                                                  then
                            make the mango shake                              make the mango shake

                                                                              ma e cold coffee

                     n such situations   e use conditional  loc s.  cratch has t o conditional  loc s. They are
                  1.  If,then block:  n this  loc  i  the condition is true  the  loc s inside conditional  loc
                      ill run.    the condition is  alse  the  loc s inside conditional  loc   ill not run.  nly the
                     blocks outside the conditional block will run.

                  2.  If,then,..else block:  n this  loc  i  the condition is true  the  loc s inside then condition
                      ill run.    the condition is  alse  the  loc s inside else condition will run.

                    You can also use the forever and repeat blocks with these blocks.
                  Let us make a small script.
                  Change the sprite to fish and change the backdrop to Underwater 2.

                  Drag the Event block, when green flag clicked to the script area. Drag the control block,
                  forever to the script area and put it to the green flag  loc .  rag the move block and put it
                  inside the forever block. Now, drag the if on edge, bounce block and put it inside the forever
                  block.

                  Now, put  the  control  block  if,then inside  the forever  block and  snap  the  sensing block,
                  touching color  in the hexagon of the if loop.
