Leveling up

The next code we will add enables the player to level-up between waves. Because of the work we have already done that makes, this is straightforward to achieve.

Add the highlighted code in the LEVELING_UP state where we handle player input:

// Handle the LEVELING up state 
if (state == State::LEVELING_UP) 
{ 
   // Handle the player LEVELING up 
   if (event.key.code == Keyboard::Num1) 
   { 
     // Increase fire rate
     fireRate++; 
     state = State::PLAYING; 
   } 
 
   if (event.key.code == Keyboard::Num2) 
   { 
     // Increase clip size
     clipSize += clipSize; 
     state = State::PLAYING; 
   } 
 
   if (event.key.code == Keyboard::Num3) 
   { 
     // Increase health
     player.upgradeHealth(); 
     state = State::PLAYING; 
   } 
 
   if (event.key.code == Keyboard::Num4) 
   { 
 // Increase speed player.upgradeSpeed(); ...
