An object has type classifiers that are not compatible with a member function.

Question

My class Gamehas a member EntityManager entityManager_.

The class EntityManagerhas a private member Player player_and a public getter function Player &EntityManager::getPlayer()that returns player_.

A class Playerhas, for example, functions void startMoving()and sf::Vector2f getPosition() const.

Now I can call entityManager_.getPlayer().startMoving();from my class without any problems Game, but when I try, for example, the following code to get the player’s position:

sf::Vector2f playerPosition = entityManager_.getPlayer().getPosition();

I get the following error:

IntelliSense:

EntityManager Game::entityManager_

Error: the object has type qualifiers that are not compatible with the member function

object type is: const EntityManager

Conclusion:

game.cpp(261): error C2662: 'EntityManager::getPlayer' : cannot convert 'this' pointer from 'const EntityManager' to 'EntityManager &'
          Conversion loses qualifiers

I tried to remove the constplayer from the getPosition function, but nothing changed.

I know that this probably has something to do with const, but I can't figure out what to change! Can someone please help me?

Answer 1

:

game.cpp(261): error C2662: 'EntityManager::getPlayer' : 
               cannot convert 'this' pointer from 'const EntityManager' to 
                                                  'EntityManager &'
          Conversion loses qualifiers

, getPlayer, / const. non-const member const const const.

this, , -, const.
