Graphics / Re: Vector of structs which contains sprites

1. "U could, as another example, pushing into the vector after u set the sprite."
When I do that - all sprites are turning to white -> because ui.back().sprite cant find texture -> because ui.back().sprite thinking that texture is in uiElement btn; but when i draw ui.back().sprite  uiElement btn; is didnt exist already.

I tried to do that before, so next step was add to std::vector<uiElement> ui; btn only with texture, then assign that texture to sprite and ui.back().sprite would link texture not from uiElement btn; but from ui.back().texture.
Aaaand that didn't work((

2. " make ur vector of pointers (uiElement*)"
At first - I initialize all elements in my class constructor. And if i use pointers - will my alements exist in memory after my constructor?
At second - I dont learn yet how to work with memory(((

3. "rather than using back(), get the address of the last element in vector"

I tried and changed my for:

for (int i = 0;i < 4;i++){
                    uiElement btn;
                    btn.texture.loadFromFile("../res/textures/button.png");
                    ui.push_back(btn);
                    Texture* t_ptr = &ui.back().texture;
                    ui[ui.back()].sprite.setTexture(*t_ptr);
}

And result was the same(( Only last button has correct texture and sprite,  the other are white(

Graphics / Vector of structs which contains sprites

« on: February 08, 2020, 01:44:41 am »

Im trying to do a vector of struct elements to draw them in RenderWindow;

my struct for non-ui objects:

struct element{
    sf::Texture texture;
    sf::Sprite sprite;
    sf::IntRect rect;
    sf::Text text;
};

my struct for ui objects:

struct uiElement: element{
    sf::Text text;
    bool clickable;
};

Im adding elements like that:

std::vector<uiElement> ui;

uiElement el;

el.texture.loadFromFile("../res/textures/background.jpg");
ui.push_back(el);
ui.back().sprite.setTexture(ui.back().texture);

and it works!But, only if my "std::vector<uiElement> ui;" has one element;

when i try to add more with cycle:

for (int i = 0;i < 4;i++){
                    uiElement btn;
                    btn.texture.loadFromFile("../res/textures/button.png");
                    ui.push_back(btn);
                    ui.back().sprite.setTexture(ui.back().texture);
}

draws only last object in my "std::vector<uiElement> ui;" and the other are just white

my drawing part of code:

for (auto & element : ui){
        window.draw(element.sprite);
}

How can I fix it??

thanks in advance
