How do I get information about the level to the player object?

Question

I have a design problem with my Player and Level class in my game.

So below is a picture of the game. The problem is I don't want to move on the black space and only the white space. I know how to do this as all I need to do is get the check for the sf::Color::Black and I have methods to do this in the Level class. The problem is this piece of code

   void Game::input()
{
    player.input();
}

void Game::update()
{
    (*level).update();
    player.update();
}

void Game::render()
{
    (*level).render();
    player.render();
}

So as you there is a problem in that how do I get the map information from the Level class to the Player class.

Now I was thinking if I made the Player position static and pass it into the Level as parameter in update I could do it. The problem is interaction. I don't know what to do. I could maybe make player go into the Level class. However, what if I want multiple levels?

So I have big design problems that I'm trying to solve.

If I understood your problem correctly, your problem is, that your player has no position on the map, if you do this. And this causes your problem with interactions, right?

The players position should never be "static". Only its position on the screen. To achieve this you should set the View port position (= camera position) relative to your players position. So the background scrolls, while the player stays at the middle of the screen.

This way you have a position of your player, relative to the map. You also have positions of things you can interact with, also relative to the map. Thus, you can implement collision / proximity detection or whatever you like easily.

EDIT #1

As you changed your questions title, I assume another possible problem. If you want the player class to get access your map...

Let us have a look at your code here...

void Game::update()
{
    (*level).update();
   player.update();
}

In this case your player.update should have the parameter "level".

void Game::update()
{
    (*level).update();
   player.update(level);
}

That's it.... the player can then access the level data.
