Control Blocks

                                         They are colour-coded gold and are used to control the scripts. This
                                         is a very important category because it controls how many times
                                         an event happens, how long an event happens, or when an event
                                         happens.

                                             To remove a block from a script, just drag it to the left, away from
                                             the Scripts pane.





                 Sound Blocks

                 They are  colour-coded  pink and are  used to control sound.

                 These blocks control the playback and volume of the sound files
                 selected by you. Drag the “start sound meow” block and drop in
                 the Scripts pane.

                     block.
