Chapter 14. Building Playable Levels and Collision Detection

This chapter will probably be one of the most satisfying of this project. The reason for this is that by the end of it, we will have a playable game. Although there will still be features to implement (sound, particle effects, HUD, and shader effects), Bob and Thomas will be able to run, jump, and explore the world. Furthermore, you will be able to create your very own level designs of almost any size or complexity by simply making platforms and obstacles in a text file.

We will achieve all this by covering following topics in this chapter:

• Exploring how to design levels in a text file
• Building a LevelManager class that will load levels from a text file, convert them into data our game can use, and keep track of the level details, such as spawn position, current level, and allowed time limit
• Updating the game engine to use LevelManager
• Coding a polymorphic function to handle the collision detection for both Bob and Thomas...
