CONDITIONAL BLOCKS

                   Scratch has two conditional blocks. They are:


                 1.    If..then block: In this block if the condition is true, the blocks inside conditional
                      block will run. If the condition is false, the blocks inside conditional block will not
                      run. Only the blocks outside the conditional block will run.

                 2.    If..then..else  block:  In  this  block  if  the

                      condition is true, the blocks inside then
                      condition will run. If the condition is false,
                      the blocks 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 butterfly and change
                      the backdrop to flowers.


                 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 block. Drag 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.

                 Now, follow the given script:
