DRAWING SHAPES


                 We have learned how to control sprites in the previous chapter. In this chapter, we will learn
                 about creating shapes. Thus, we can repeat the actions of a stack of blocks by making use
                 of the various blocks in the Control block category.



                 PEN BLOCK
                 Pen blocks provide a trail for the sprite and give instructions to change the colour, size
                 and shade of the trail. These blocks are colour-coded as dark green and used to draw

                 shapes in Scratch. We can add pen blocks by clicking on the Add Extension button, then
                 clicking on Pen extension to add it. Let us read pen blocks and their functions.



                                   Blocks                                            Functions




                         pen down                               It places the pen in the down position.



                         pen up                                 It disables  drawing operations  by  lifting  the
                                                                pen.


                         set pen color to                       It specifies the colour to be used while drawing.

                                                                It modifies the thickness of the pen. You can
                                                                also change the thickness  by writing the
                         Change pen by  1
                                                                desired number in the number box, number 1
                                                                being the least thick.


                         stamp                                  It draws or stamps the image of a sprite onto
                                                                the stage.


                         erase all                              It erases the pen marks from the stage.



                 Drawing A Line
