General / Re: Write a text when an object/or shape is clicked

« on: November 23, 2020, 02:22:28 am »

I suppose writing the text so it is shown on the screen. Here's what I try to do, when I click on the shape, I wasn't able to write anything:
Typing.h

    void draw(sf::RenderTarget &window, sf::RenderStates state) const;

};

    test.setPosition(bounds.left+20,bounds.top+30);

    background.setFillColor(sf::Color::White);
}

General / Write a text when an object/or shape is clicked

« on: November 22, 2020, 10:00:32 pm »

Hello, can anyone help me with this problem. I'm trying to set up something like when I click on an object(or a shape), I would be able to write something inside of that object/shape. Thank you!

Anyway, I've fixed it by changing the setPosition in Box::setPosition to left and top instead of width and height.

To be more precise, Box test(1,1) (regardless whether which instances are declared first) is the only instance where the sprite is drawn, all the other instances of box just draw the rectangle shape and not the sprite.

Well, as I said, the first intance of the class, the image is loaded properly, however for the subsequent instances, only the rectangle shape is drawn and not the sprite. Specifically, in the main.cpp file, "Box test(1,1)" is drawn properly with both the rectangleshape and the sprite, but for the "Box test1(2,2)" only the rectangle shape is drawn and not the sprite.

Graphics / Sprite fail to load when creating multiple objects

« on: November 06, 2020, 02:09:44 am »

Hi guys, I've encountered a problem when trying to draw objects, and I think that it might have something to do with sf::Sprite or sf::Texture, I'm not sure. Basically, my object consist of a rectangle shape and a sprite, when I try to draw it for the first object everything is exactly how I pictured it. However, the problem arise when I try to different objects of the same class. Specifically, for the subsequent objects drawn, only the rectangle shape was showing and not the sprite. How can I fix this problem? Here's my code:

Graphics / Re: Help with drawing NQueens problem using 2D arrays of objects

« on: November 05, 2020, 10:05:46 pm »

The problem seems to in the following: Board::addQueen in Board.cpp; and when declare the Box at: "class Box:public sf::Drawable, sf::Transformable", I think.

Graphics / Help with drawing NQueens problem using 2D arrays of objects

« on: November 05, 2020, 02:14:40 am »

Hello everyone, I try to run a program to draw an empty chess board(each tile inside of the chess board is categorized as box) save for the queen piece at the position derived from the NQueens algorithm. My nqueens algorithm is correct, because I tested it, and It was able to give the correct position in the board(as in it was able to give me the correct rows, and columns of the queen). However, when I try to draw the whole thing, the window pop up in a white screen and close immediately without showing anything, while the terminal shows: "Process finished with exit code -1073741819 (0xC0000005)". Can you help me with this problem? Here's my code, and it is a bit lengthy as I manually implement a custom stack of queen using linked list( but I think you only needs to take a look at the nqueens, queen, box, board files, the others are irrelevant):
