Building the LevelManager class
It will take several phases of coding to make our level designs work.
The first thing we will do is code the LevelManager header file. This will allow us to look at and discuss the member variables and functions that will be in the LevelManager class.
Next, we will code the LevelManager.cpp file, which will have all the function definitions in it. Since this is a long file, we will break it up into several sections to code and discuss them.
Once the LevelManager class is complete, we will add an instance of it to the game engine (Engine class). We will also add a new function to the Engine class, loadLevel, which we can call from the update function whenever a new level is required. The loadLevel function will not only use the LevelManager instance to load the appropriate level – it will also take care of aspects such as spawning the player characters and preparing the clock.
Now, let's get an overview of LevelManager by coding...
