Page 89 - Learn To Program With Scratch

Proce Du r e S

This chapter explains how you can take a “divide

and conquer” approach to programming. Rather
than build your programs as one big piece, you’ll be
able to write separate procedures that you then put
together. Using procedures will make your programs

both easier to write and easier to test and debug. In
this chapter, you’ll learn how to:

• Use message broadcasting to coordinate the behavior of many sprites
• Use message broadcasting to implement procedures
• Use the “build your own block” feature of Scratch 2
• Use structured programming techniques
