Populating the sound emitters

Open the Engine.h file and add a new prototype for a populateEmitters function and a new STL vector of Vector2f objects:

   ... 
   ... 
   ... 
   // Run will call all the private functions 
   bool detectCollisions(PlayableCharacter& character); 
 
   // Make a vector of the best places to emit sounds from
   void populateEmitters(vector <Vector2f>& vSoundEmitters,
     int** arrayLevel);

   // A vector of Vector2f for the fire emitter locations
   vector <Vector2f> m_FireEmitters; 
    
public: 
   ... 
   ... 
   ... 

The populateEmitters function takes as a parameter a vector of Vector2f objects, as well as a pointer to int (a two-dimensional array). The vector will hold the location of each emitter in a level and the array is our two-dimensional array, which holds the layout of a level.

Coding the populateEmitters function

The job of the populateEmitters function is to scan through all the elements of arrayLevel and decide where...
