In Detail

Playing video games is fun, however, it's even more fun to make your own! Scratch 2.0 makes that challenge a lot easier. Instead of diving into abstract and confusing code, you can build games using easy to understand logic blocks. Within minutes you can have your first game up and running.

Readers can look forward to an easily accessible and fun introduction to programming and interactive media design. Within minutes of starting the program, you will be able to see the first results of your hard work. Visual feedback comes early and often, making high-level, abstract concepts a lot easier to understand.

This book offers readers access to completely interactive projects based on well-known video game genres. You will then learn how to use standard programming principles such as operators, variables, and functions.

From a broader perspective, you will also learn how to plan and develop a game from a general idea to the finished product, creating a fun and user-friendly game. Scratch 2.0 includes many new and exciting features, which makes it possible to create more advanced games. The final results will be close to production level games. This book will not only introduce you to the Scratch 2.0 software, but also teach you about interactive media design.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

computer if you're looking for an image on your own. 2. Start a new Scratch project and remove the cat sprite. 3. Click on the folder icon underneath the Stage thumbnail. This will open the file browser of your computer. 4. Navigate to the folder where you saved your map image. 5. Click on the image and select Open. This image will now be loaded as a backdrop. The image will be shown in the Backdrops editor in its actual size or as big as possible if it's bigger than the stage area. Your

the lessons learned here and apply them to create games with tool sets other than Scratch. We hope you enjoy working on the projects in this book. May they inspire you to create even better games! What this book covers Project 1, Blowing Things Up!, builds a simple game involving a cannon and some targets. You will learn about placing sprites, building scripts, and setting the game in motion. Project 2, Beating Back the Horde, teaches you how to create multiple enemies and how to move them along

screen. From there, we will use the cloning method to generate waves of starfish moving left towards the player character by following these steps: 1. Start with a when clicked block. 2. Let's click on hide to make the sprite invisible when not needed. 3. Also, enter the value 30 in the set size to ()% block to make it smaller. It should be about the same size as the diver. 4. Add a forever loop to hold the clone generation script. We will make the sprite jump to a random

Then, we set the scrolling speed to -2 in the set to () block. We use a negative value because we want the background (and all other objects still to come) to scroll left. The following screenshot shows the final script: That was all we needed to add to make the script work. Let's test it again. We'll see that the background sliding towards the left until it is out of view. Then it comes sliding in from the right again. 151 Shoot 'Em Up The only thing left to do is copy the

upgraded spear on the boss. 4. Then we use broadcast to start the boss phase immediately. 176 Project 6 The final script will look like the following screenshot: This is all that is absolutely necessary for this script. As you can see, the timer is still running and will eventually reach 90. This would cause the boss message to be called again. We don't want that as it could cause strange results. So, we will take a few precautions to prevent the timer from ever reaching 90. Stopping
