General discussions / SFML media demo - Linking error on windows 10

« on: April 28, 2018, 05:41:17 pm »

 I tried with the sfml media demo code (https://www.sfml-dev.org/documentation/2.4.2/). I can build and run with CLion on mac os x. However, I am having the following linking error on windows 10 with CLion. I wonder whether I need extra setup on windows 10. By the way, I don't have any D: drive. I installed SFML to C:\SFML.

I wonder whether it is possible to set the top,left,right, and bottom outline with the different colors.

General / Re: how to create a grid?

« on: April 25, 2018, 09:56:06 pm »

I am trying to do the similar task by creating the Grid class. Basically, I am trying to create 2D sf::RectangleShape arrays. The following is the snippet of the code.  However, when I try to draw by looping through each element in Rects[][], it doesn't show any. Can anyone advise the mistake(s) that I made?

Thanks!!


#include <SFML/Graphics.hpp>

class Grid {
private:
    sf::RectangleShape** Rects;
    sf::RenderWindow *gridWindow;
    int row;
    int col;
public:
    Grid() {
    }
    Grid(int r, int c, sf::RenderWindow *window): row(r), col(c), gridWindow(window) {
        int w = gridWindow->getSize().x * 1.0 / row;
        int h = gridWindow->getSize().y * 1.0 / col;

        Rects = new sf::RectangleShape*[r];
        for (int i = 0; i < row; i++)
            Rects = new sf::RectangleShape[col];

        // need to create an actual cell
        int baseX = 100;
        int baseY = 100;

        for (int i = 0; i < row; i++) {
            for (int j = 0; j < col; j++) {
                Rects[j] = sf::RectangleShape();
                Rects[j].setPosition(baseX, baseY);
                Rects[j].setFillColor(sf::Color::Yellow);
                Rects[j].setOutlineColor(sf::Color::White);
                Rects[j].setOutlineThickness(10);
                baseX += w;
            }
            baseX = 10;
            baseY += h;
        }
    }

General / help : SFML_2_4_2_osx_clang build error on macOS High Sierra

« on: April 19, 2018, 04:33:29 pm »

I downloaded the SFML_2_4_2_osx_clang from https://www.sfml-dev.org/download/sfml/2.4.2/.

Inside the project source directory, I created build subdirectory.

cd build
cmake ../.       (attachment: cake-log.txt)
make              (attachment: make-log.txt)

The following is the snippet of the make error. It appears that I need to properly set CMakeLIsts.txt for OpenGL library ?? Any help will be appreciated.

I am trying to build SFML from the SFML_2_4_2_osx_clang project source and I am having a build error on macOS High Sierra 10.13.4.

(1) First, I created a directory 'build'
(2) cd build
(3) cmake ..
(4) make

I am attaching 2 log files for your info - one is for cmake and the other is for make. Thank you for your help in advance.
