Is there any way to find out if an object belongs to a class in c++?

Question

OOP

I have (not yet but before I get started I need to sort things out) an array of game objects. These are different classes that inherit from one (Object, for example). That is, they are all Object.
But how do I understand that an element of this array is not only an Object in general, but also, for example, a player or an enemy or a wall or something else?
In js I would write:
if (objects[i] instanceof Wall) { ... }
But how to do this with C++? And without crutches.
Or maybe I do not understand correctly how such things are done in C ++? If yes, how is it organized?

Answer 1

Why do you need this? There is polymorphism, and castes are bad style almost always.
You can use a lot of things, including tags. In the base class, you create an enum, where each element is the type of the descendant + 1 element per type of the base class. In the base class, you define a virtual method like type() and implement it for all descendants.
But before you do this, think carefully about whether you need it. Read about SOLID, especially about the letter L.

Answer 2

Read this for example:
https://stackoverflow.com/questions/1986418/typeid...
especially the answer.
Somewhere I saw another implementation through templates.
But 90% something is wrong with the architecture if this is necessary. And if you really need to and inherit from the base class, then make a method in the base class that will return the type by enum.
