Passing arguments in classes - Error: no function to call

[JasonMcG]

I have a class called Rock and I'm passing in my player class.

Code: [Select]

Rock::Rock(Player& player){
    _rock.setTexture(_rockTexture);
    _rock.setOrigin(650,500);
    _rock.setPosition(X, Y); 

   _player = &player;
}

In my Game glass, which is the game engine, I get an error

Code: [Select]

Game::Game():
    _window(sf::VideoMode(WIDTH, HEIGHT), "ROCK"){

}

Error: no function to call Rock::Rock()

I assume this is because rock is taking a parameter.
But in Game:Game, how am I supposed to define something here to satisfy this error?
I tried making the Rock object in Game a pointer by that crashes the program.

If I had to pass any argument into the Rock constructor, how do I satisfy it in the Game class?

The same way you pass the arguments to the window constructor

Game::Game():
    _window(sf::VideoMode(WIDTH, HEIGHT), "ROCK"),
    _rock(player) // I assume that your Rock instance is named "_rock", and that you have a Player instance named "player"
{
}
