We already determine the size of the arena and the number of zombies by the value of the wave
variable. We must also reset the ammo, gun, wave
, and score
to zero at the start of each new game. Find the following code in the event handling section of the game loop and add the highlighted code:
// Start a new game while in GAME_OVER state
else if (event.key.code == Keyboard::Return &&
state == State::GAME_OVER)
{
state = State::LEVELING_UP;
wave = 0;
score = 0;
// Prepare the gun and ammo for next game
currentBullet = 0;
bulletsSpare = 24;
bulletsInClip = 6;
clipSize = 6;
fireRate = 1;
// Reset the player's stats
player.resetPlayerStats();
}
Now we can play the game, the player can get ever more powerful and the zombies will get ever more numerous within an arena of increasing size - until he dies then it all starts again.
