Trying to use Vectors with SFML - c++

Question

Everytime I run the code it says
Vector subscript OUT of range.
I've looked at other SFML vector Questions on "stackoverflow" and none of them have answer of my questions or worked. What I'm trying to do is:
vector<sf::Sprite> snake_part;
sf::Sprite sprite;
for (int i = 0; i <= 10; --i) {
snake_part.push_back(sprite);
cout << "Vector size : " << snake_part.size() << endl;
snake_part[i].setTexture(Snake_Part_Texture);
if (i > 0) {
x1[i] -= 10;
}
}
This is the Part of the code that doesn't work.
OUTPUT:
Vector size : 1
Vector size : 2
It's supposed to count to "10", but stops at "2" for some reason and Comes with the "Vector subscript out of range" error as well.
Full Code:
#include <SFML/Graphics.hpp>
#include <iostream>
#include <vector>
using namespace std;
int main() {
//=========================================================
// Coordinates
float y = 330; float x = 150;
float x1[10]; x1[0] = x;
float y1[10]; y1[0] = y;
// Texture
sf::Texture floorText;
if (!floorText.loadFromFile("Floor_Snake_SFML.png")) {
cout << "Floor_Snake_SFML.COULD_NOT_LOAD: [Error]" << endl;
}
sf::Texture Snake_Part_Texture;
if (!Snake_Part_Texture.loadFromFile("Snake_Part_Sprite.png")) {
cout << "Snake_Part_Texture.COULD_NOT_LOAD: [Error]" << endl;
}
// Sprite_floor
sf::Sprite floor;
floor.setTexture(floorText);
floor.setPosition(0, 320);
// vector <sprite> -- (snake)
vector<sf::Sprite> snake_part;
sf::Sprite sprite;
for (int i = 0; i <= 10; --i) {
snake_part.push_back(sprite);
cout << "Vector size : " << snake_part.size() << endl;
snake_part[i].setTexture(Snake_Part_Texture);
if (i > 0) {
x1[i] -= 10;
}
}
//=========================================================
sf::RenderWindow window(sf::VideoMode(640, 480), "<snake>");
while (window.isOpen()) {
sf::Event event;
while (window.pollEvent(event)) {
switch (event.type) {
// Close Window
case sf::Event::Closed:
window.close();
break;
// Do [x] if KeyPressed-
case sf::Event::KeyPressed:
switch (event.key.code) {
// [A] -pressed-
case sf::Keyboard::A:
for (int j = 1; j <= 10; j++) {
x1[j] = x1[j - 1]; y1[j] = y1[j - 1];
}
x1[0] -= 10;
for (int k = 1; k <= 10; k++) {
snake_part[k].setPosition(x1[k], y1[k]);
}
break;
// [D] -pressed-
case sf::Keyboard::D:
break;
// [Space] -pressed-
case sf::Keyboard::Space:
break;
}
break;
}
}
window.clear(); // ===============================
window.draw(floor);
window.draw(snake_part[0]);
window.display(); // ===============================
}
return 0;
}
If you want a more detailed Error and synopsis of the Program, just comment, Also thanks in Advance, and if anyone know a better way instead of Vector to create 10 Sprites without having to do this 10 times:
sf::Sprite sprite;
sprite.setTexture(texture);
sprite.setTextureRect(sf::IntRect(0, 0, 10, 10));
float x = 320, y = 240;
sprite.setPosition(x, y);
then I would be REALLY grateful.
-Thanks in advance.

Answer 1

The error more than likely comes from this line:
for (int i = 0; i <= 10; --i)
I don't know what you meant to do with that line, but more than likely it was supposed to be ++i instead of --i.
