Displaying Arrays

[Jalfor]

How would I go about displaying an array of shapes. I am trying to make a game of snake and I need to create a grid which can be individually color changeable for obvious reasons. Here is the code with all the irrelevant bits cut out.

 

Code: [Select]


#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>
#include <iostream>

int main()
{
int count = 0;
        int count1 = 0;
sf::Shape grid[10][10];

int x1 = 120;
int y1 = 100;
int x2 = 100;
int y2 = 80;

    sf::RenderWindow App(sf::VideoMode(800, 600), "Snake");

    while (App.IsOpened())
{
       
App.Clear();

for(int xdot = 0; xdot < 10; xdot++)
for(int ydot = 0; ydot < 10; ydot++)
{
grid[xdot][ydot] = sf::Shape::Rectangle(x1 + xdot * 22, y1 + ydot * 22, x2 + xdot * 22, y2 + 22, sf::Color::Red);
}

       
App.Draw(grid);    //That's really what I want to do though it's giving me a syntax error
App.Display();
    }

    return EXIT_SUCCESS;
}

You need to initialize the array only once, not every frame (i.e. before the main loop). Inside the loop, you can draw every shape:

Code: [Select]

for(int xdot = 0; xdot < 10; xdot++)
     for(int ydot = 0; ydot < 10; ydot++)
     {
        App.Draw(grid[xdot][ydot]);
     }
