General / How can I make a background repeat infinitely?

« on: January 18, 2023, 08:58:40 pm »

Hi!

I'm currently working on a game and I am trying to make the background repeat infinitely (Tiling) as the character moves towards +X or -X position. Reading the documentation and some older posts in this forum I found the SetRepeated(); function, however, it does not work as I wish it to as it will only work if the texture is smaller than a defined rectangle type, but as this is a background texture I could not make the rectangle infinitely large.

What I'm currently looking for is a way in which I could repeat the texture to the X axis infinitely as the game is supposedly infinite.

The current code that I have for the texture and the background is the following:

//BG
    sf::Texture bgText;
    sf::Sprite bg;
    sf::Vector2u TextureSize;
    sf::Vector2u WindowSize;

 if (!bgText.loadFromFile("Media/Background.jpg"))
    {
        return -1;
    }
    else
    {
        TextureSize = bgText.getSize();
        WindowSize = window.getSize();

        float ScaleX = (float)WindowSize.x / TextureSize.x;
        float ScaleY = (float)WindowSize.y / TextureSize.y;

        bg.setTexture(bgText);
        bg.setScale(ScaleX, ScaleY);
    }
 

I would appreciate any suggestions on how I could do this, many thanks

P.S: I'm doing everything in the main function without making use of any other functions.
