I want to optimize my code

[Mariusmssj]

Hello guys if you remember few days ago i was going crazy with trying to make my game work. Well the game works and it's all good, but i am really unimpressed with how the code looks and is managed.

i got 6 classes in total in order to make the code better but my main still looks like a mess. I went over it few times, changed few bits and added comments.

Could anyone see where it would be improved?

thank you very much

	std::vector<Zombie> zombies(zomb);
	std::vector<Hole> holes(hol);
	
	//randomly sets the postion of the man
	a_man.set_position();
