Chapter 10 – Working with Tilemaps

This chapter dives into the depths of the CCTMXTileMap class and how to create, iterate and modify tilemaps in code, including isometric and hexagonal tilemaps. Of course there will be an introduction to the Tiled Map Editor as its the primary tool to create TMX tilemaps that cocos2d supports.

The chapter 11 will then use this newfound information and I’ll walk you through making a scrolling tilemap game, since simply loading, modifying and displaying a tilemap would just be half the story.

Summary of working on Chapter 9 – Particle Effects

This chapter was fun. Particle effects are fun indeed. That is, unless you need to tweak them in code only. I did do that an did my best to describe what each CCParticleSystem property does to a visual effect, although some things you’ll have to see for yourself. You’ll find a lot of detailed information on how to setup or simply modify a particle system in code and a couple tips for designing good particle effects.

Of course with Particle Designer everything changes. Designing a cool particle effect suddenly goes from a treadmill to a mesmerizing activity that you can waste countless hours on. If you check Particle Designer’s Online Library you’ll find four of the Particle Effects that I designed and submitted, starting with the “Colorful Burst” effect. Have a look!

Obviously these cool effects needed to go somewhere, so I added them to the Shoot ’em Up game as you can see in the screenshot (the boss just exploded into purple smudge). Along the way you learn how to load the particle effects created by Particle Designer of course.
