This chapter presents a new challenge for us because we're starting with somebody else's work. This means we'll have to spend some time figuring out what the existing code does before we can make our customizations and build a new game.
In this chapter, we will:
Analyze and customize an existing Scratch project to create something new
Define and interpret variables to evaluate dynamic data
Control the actions of the sprites based on conditional information
Let's create our version of the classic arcade game Pong.
Troll pong
Let's flash back to 1972 and create a clone of the popular Atari video game Pong. Instead of starting this program from scratch, we're going to start with a sample project that we can use as a basis for our creativity.
