Title: (SOLVED) sf::Sprite.getTexture() Help?
Post by: TheGoldenFyre on January 02, 2016, 10:05:39 am

Can someone show me how you would be able to do something like this?

Code: [Select]

if (Sprite[i].getTexture() == Texture) {
                      //code
}
I just can't get it to work.
Thank you for any help!

AMD A6-6310 APU, Windows 10. SFML 2.3. Visual Studio 2015 community. Everything else works fine, i'm just wondering how .getTexture could be used in an if-statement, and searching for it doesn't help.

What doesn't work?

What are you attempting to do?
Comparing two textures to see if they contain the same data? You should be using sf::Image for this.
Comparing two textures to see if they are the same texture object? You can use pointers/addresses:
if (sprite.getTexture() == &texture)
sf::Sprite::getTexture() (http://www.sfml-dev.org/documentation/2.3.2/classsf_1_1Sprite.php#a2c4fbb983b29e14f9bb69a3a75feae46) returns a pointer to a texture, not a texture itself (not that you can compare two texture objects anyway).

The link that Nexus posted doesn't say "provide your computer details", it is a very important post that says that you should give enough information about the problem and what actually goes wrong/doesn't work.

I'm trying to see if two textures are the same. The base texture (the texture itself) and the texture that is assigned to the sprite. I don't know how I would do this, mainly because I don't understand what the .getTexture returns and how to use it for a comparison.

Again, I ask: the same data in each texture or both pointing to the same object?

Even though I answered your question (twice), I'm feeling generous.

(click to show/hide)

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

int main()
{
        sf::Texture texture1;
        sf::Texture texture2;
        if ((!texture1.loadFromFile("image.png")) ||
                (!texture2.loadFromFile("spritesheet.png")))
                return EXIT_FAILURE;

        sf::Sprite sprite(texture2); // this can be set to texture1 or texture2

        if (sprite.getTexture() == &texture1)
                std::cout << "Sprite is using texture 1." << std::endl;
        else if (sprite.getTexture() == &texture2)
                std::cout << "Sprite is using texture 2." << std::endl;
        else
                std::cout << "Sprite is not using texture 1 or texture 2." << std::endl;

        return EXIT_SUCCESS;
}

I'm so stupid. Thanks anyways for the help, hope this works wel XD.
