I am creating an Uno game and I am stuck trying to search through an a vector of objects by specific attributes. It crashes when the program reaches the Game::player_selection() method. Other than the , everything is working.
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
class Card {
public:
string get_colour();
string get_type();
};
class Player {
public:
vector<Card*> get_hand(); //Should this be a reference?
private:
vector<Card*>current_cards;
};
int main() {
srand(time(NULL)); //Makes shuffle more random (different every time)
Game my_game;
Player new_player("Hank", "human");
Player jack_player("Jack", "human");
my_game.add_player(new_player); //Must create players before doing other tasks
my_game.add_player(jack_player); //Must create players before doing other tasks
my_game.setup_game();
my_game.display_players();
cout << "enter colour" << endl;
cin >> colour;
cout << "enter type" << endl;
cin >> type;
my_game.play_card_to_pile(my_game.player_selection("Jack", colour, type));
my_game.display_players();
Game.cpp
Card* Game::player_selection(string p_name, string colour, string type){
vector<Player>::iterator p_iter;
vector<Card*>::iterator c_iter;
p_iter = find_if (game_players.begin(), game_players.end(), [&] (Player& p) -> bool{return p.get_name() == p_name;}); //Finds correct player
c_iter = find_if(p_iter->get_hand().begin(), p_iter->get_hand().end(), [&] (Card*& c) -> bool{return c->get_colour() == colour && c->get_type() == type;}); //Finds correct card
return (*c_iter);//Should return correct card
}
Error given
Edit
Just posting here for future reference regarding find_if checks and multiple copies of vectors. So the solution was:
Card* Game::player_selection(string p_name, string colour, string type){
vector<Player>::iterator p_iter;
vector<Card*>::iterator c_iter;
p_iter = find_if (game_players.begin(), game_players.end(), [&] (Player& p) -> bool{return p.get_name() == p_name;});
if (p_iter != game_players.end()){
vector<Card*> hand = p_iter->get_hand();//Otherwise have multiple copies of the vector stored in different places in memory
c_iter = find_if(hand.begin(), hand.end(), [&] (Card*& c) -> bool{return c->get_colour() == colour && c->get_type() == type;});
if (c_iter != hand.end()){
return (*c_iter); //If found return found Card
}
}
return (get_pile_card()); //Else return a default
}
