You can also use the forever and repeat blocks with these blocks.

              Let us make a small script.

                Change  the sprite to  butterfly and change the backdrop to

              flowers.

              The butterfly changes colour and size when it touches the colours
              selected in the touch block.

              Similarly, you can create scripts with two sprites, and they change

              colour when they touch each other.



























                   LOOPS


              All the programs or projects developed till now ran only once. If you want to run a set of
              statements more than once, you can either run the code again or write the script again. In

              Scratch, we can save our time and effort by repeating the code without writing the program or
              script again. The automatic running of a set of instructions more than once is called looping.
              The blocks for looping are given in Control category.
                                                                                                           repeat  10
              The Repeat block is used to run a set of instructions for a specified number of

              times.
                                                                                                       repeat  until
              The Repeat until block is used to run a set of instructions till a condition is
              satisfied.

              The Forever block is used to run a set of instructions continuously until stopped.           forever

              The instructions inside this block will be executed in a loop until the Stop button
                   is clicked by the user.
