SFML | Simple and Fast Multimedia Library | Game Engine library

I had a program working good (without prompting errors) using references, but I decided to use a pointer-to-pointer array allocated on virtual memory, because I can use a variable as the size of the array.

The error prompts when I break the while (m_Window.isOpen()) loop, in other words when I close the game window and the game is finished. I have noticed that the program breaks when I try to erase the virtual memory in the Engine::cleanVirtualMemory() function. I have noticed that it is there because I have put two flags (cout << "running1" << endl; and cout << "running2" << endl) and I can show just the first flag.

Then it prompts a window with the following message:

HEAP CORRUPTION DETECTED after normal block.. CRT detected that the application wrote to memory after end of heap buffer

main.cpp

I have a project which is using a few libraries where each one of the libraries define some sort of 3D vector, as an example I use SFML's 3D vector in some parts of the code, reactphysics3d's Vector3 on others, and yet another 3D vector from another library.

Now I need to code the cross product and the std::ostream &operator << for each one of the vectors:

I am currently working on moving a camera in 3d space. I want it to move ONLY in the x and z-axis (horizontal). So far it was moving correctly when the rotation of the camera is all zero, but when I change the value of it, the camera starts to act a little weird, moving in the wrong direction. I am using SFML, but I think it's the math that causes the problem. It is weird because the code I move the camera is identical to one of the projects I wrote earlier, but the project works fine.
Here's the code that constrains the rotation:

I want to use the new parallel facilities of C++17 but my computer don't.

This works :

In the code I wrote, the collision is detected correctly, but only 1 enemy changes players texture. What is the reason and how can I change players texture for every enemy? The problem is between lines 56 and 64 of the code.

Screenshots :

No collision

Collision but texture isn't change

Collision and players texture is changed

I'm trying to draw simple graphics in the .NET Interactive Notebook, using C#. Kind of like a C# version of Dr. Racket.

The simplest thing I've seen so far is using System.Drawing (SFML.NET, Raylib-cs work too, but they open up a window to show graphics instead of within the notebook).

I'd be willing to try another recommendation with #r "nuget:" too.

The problem seems to be related to the MIME type, but I'm not sure. I get the same results with both .dib and .ipynb

Is there a way to use something like .Display() and show the simple image within the notebook?

I have set up VS code as my development environment and used MSVC build tools (cl.exe compiler) instead of g++. I tried to set up SFML for my environment. I want to know how do I set the SFML include path and library path. And also, How do I perform static Linking with cl.exe. Note: I am using only VS code and NOT Visual Studio for programming. Below are some files I've used. Tasks.json,Launch.json, C_cpp_properties.json.

Hello im trying to build my own library in c++, and after many hours of searching and trying i learnt that a good way of doing one would be using nested classes, so i made some code in this form of tree: file tree

So i divided all the class files into different header files(i know this is harder and maybe not necessary but i wanted have it like that, if nothing more then just for training). And so to keep the nested class connected, but in different files, each header needs to include its child and or parent to function correctly. This didnt work, gave me errors of recursive include (duh) so i searched online and found #ifndef and #define and i used them in this way:

I tried to create a Button class and use it with SFML, unfortunately, it produces the error:

no matching function for call to 'sf::RenderWindow::draw()'|

and a few more.

This is the code:
