I'm trying to make Asteroids using the olcPixelGameEngine. I have a simple triangle sprite for the ship. I want to know how I would "include" this sprite while building. The only way I have found to do this is to place it right next to the binary in the build folder, which I don't want to do because I have read is bad practice.
Can somebody help, please? I am using Xcode 11.4.1

I'm new to openCV and I'm using 3.4.1_5, C++ in Xcode on Mac. I used Homebrew to install opencv.
I'm following an openCV tutorial which is conducted in VS on Windows. Here's a link to the tutorial.
Basically, the tutorial shows how to create/resize a window, which is easy. So I have some code like this which is basically the same as in the tutorial:
#include "opencv2/opencv.hpp"
....
namedWindow("modi", CV_WINDOW_FREERATIO);
imshow("modi", modi);
resizeWindow("modi", modi.cols/2, modi.rows/2); //modi is a Mat
....
Supposedly, the image will be the same except it will be 1/4 of the original size and fit into the resized window. This is the case in the tutorial. However, it's not the case on my mac. My image stays the same size, and only the window shrinks to 1/4. If I drag the border of the window, the "covered" part of the image is revealed.
This actually poses a problem to my project later on, so I want to figure out why. I want to achieve what the tutorial achieves, and I've tried all window parameter, like AUTOSIZE, KEEPRATIO, OPENGL, etc. None of them worked. I'm thinking about if it's due to platform or version problem, but I have no way to test them.
Please help! Any hints would be greatly appreciated!
I am making a C++ project where I need to show the images with certain points in a GUI.
Till here its simple using highGUI but problem happens with my next requirements.
I need to use the points drawn in the GUI and drag it to some other point and get that point.
I know openCV doesn't support this much requirements in GUI, so what other options are left to me?
One option that I see is using QT, also is it possible for me to use Objective C window .xib and use it together with my c++ project?
PS : HighGUI does take mouse input, but what I want is to create a point and drag it to some other point in the GUI window and then get the coordinate.
I am extremely new on both c++ and qtcreator. At school I asked for draw a line between 2 crossed corner of an image. I am planning to use the Bresenhams Algorithm to calculate the line however I don`t know anything about the graphics library.
Can you tell me how to put a dot to a point which calculated by the algorithm?
Your question is too vague. qtcreator is just a GUI for QT development, there is graphic library in QT that should be used for your purposes, but anyway, you should gain some level in c++/qt (i.e. not to be an "extremely new") to successfully utilize it.
I have created Universal project in cocos2d Level Helper and create body of object in Sprite Helper but when I run the project in XCode simulator the physics simulation is not working.
I tried to check but the LHSprite.body is Null.
Help me to how I make Universal project in Level Helper.
You mentioned about Universal project, does your project currently work on ipad or iphone?
Make sure your physics objects are not all static. you can change it in spritehelper or levelhelper
Do remember setup Physic Boundaries and Game World Size in Levelhelper properly.
Actually, I think the most possible reason could be Physic Boundaries:-)
Im trying to make a simple 2D application, and our image processing professor has told us to use opengl. Im working with c++ and QT.
I want to open a simple window that holds a place where I can draw points of different colors. All by code, there is no user interaction. I cant use any other library, can anyone tell me how to do this?

2D Painting Example using QGLWidget.
OpenGL is a library to render. You need at least one or two more (at least to create a window).
Since that is a homework, take a look at this example on how to do your assignment.
Qt comes with numerous examples of using QGLWidget.
