std::vector with SFML 2.0 Sprite.

[Tweezy]

Hi all, I am using vectors to loop the amount of sprites that are rendered to my game screen.

//load the invaders images
        sf::Texture invaderTexture;
        invaderTexture.loadFromFile("images/invaders.png");
        std::vector<sf::Sprite> invaderSprites(10, sf::Sprite(invaderTexture));

        while (App.isOpen())// Process events
        {
                for (int i = 0; i < 5; i++)
                {
                        invaderSprites[i].setPosition((60*i) + 50, 10);
                }
                for (int i = 0; i < 5; i++)
                {
                        App.draw(invaderSprites[i]);
                }
                App.draw(back);
                App.display();
               
        }

This works perfectly, and I also found out that I was stupidly rendering the invaders and then the screen in past "issues". Now, SFML 2.0 classes aren't working with this code if they are out of the for loop:

Error: class "std::vector<sf::sprite, std::allocator<sf::Sprite>>" has no member "setPosition"

Putting everything in my for loop will just, diminish certain working parts for my game. I've tried doing

sf::Sprite<SpriteNameHere> but that wont rectify my issue. Any ideas here? Will this be one of the issues where I have to change everything?

Show the code that does not work.

That always comes up if I use invaderSprites out of the for loop, which I do a hell of a lot of times, without showing all of my code I don't see how it helps.

invaderSprites.setPosition(10,10);

I know it has got something to do with having it inside a vector, as if I just used a normal sf::Sprite invaderSprite(invaderTexture); then the loop no longer works so I have to use this vector.

invaderSprites is a vector.
invaderSprites[i] is a sprite.

It's like food (sprites) inside a fridge (vector), and you're trying to eat the fridge.

std::vector<sf::Sprite>invaderSprites(10, sf::Sprite(invaderTexture));

I was thinking it may of been something to do with the vector, but sf::Sprite is still in there so I kind of went away from that sort of thinking

Do you know C++ or programming? Using an array or a vector is basic (and important), your lessons (or tons of resources on the internet) probably explain it better than I could.

invaderSprites.setPosition(10,10); calls setPosition on the vector, and vector doesn't have a setPosition method.
invaderSprites[i].setPosition(10,10); calls setPosition on the element which is at  the i index in your vector.

If you want to call setPosition on a particular sprite, you have to access it by its index.

In plain post text [ i ] turns into italics..
That's so funny in here..
Too bad you edited it out..

I'm learning c++ but I've only had one lecture on vectors. I guess my original assumption of needing to edit my layout is correct?

I know about arrays too.

What?

What?

.G made funny error that he removed before you seen it. Don't mind it.

Okay. Could you possibly help with this?

To do something with all elements of the vector you have to loop through it, there is no other way.

Thought so.

Thanks you all for making my mind up lol
