Why sprite not showing up after i use sf::setOrigin

[guuest]

why

here code:

#pragma once

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

namespace p_1{

    class Player{
        public:
            Player(sf::Texture &b, sf::Texture &p_t2_, sf::Vector2u img_count,
            float switch_time, float speed) : animation(&p_t2_, img_count, switch_time){
                sprite.setTexture(p_t2_);
                sprite.setScale(sf::Vector2f(2.f, 2.f));
                sprite.setPosition(640/2, 480/2);
                this->speed = speed;
                this->face_r = true;
                const sf::Vector2f spriteSize(sprite.getGlobalBounds().width/2.f, sprite.getGlobalBounds().height/2.f);
                sf::Vector2u size = b.getSize();
                //sprite.setOrigin(size.x / 2, size.y / 2);
               
            }
            virtual ~Player() = default;
        private:
            sf::Sprite sprite;
            unsigned int row;
            int speed=0.0f;
            bool face_r=false;
            Animation animation;
        public:
            void draw(sf::RenderWindow& window);
            void update(float dt);
            sf::Vector2f getPosition(){
                return sprite.getPosition();
            }
    };
}

You are setting the origin to half of the background texture size instead of half of the sprite texture size.
That would make the sprite appear half a screen to the left and above where you wanted it.

[guuest]

How do i get sprite size? like this:

sf::Vector2f s_size = sprite.getSize();

or how do i get the sprite texture size?

[guuest]

I already did as you said it still don't work:

sf::Vector2u size = p_t2_.getSize();
                sprite.setOrigin(size.x / 2, size.y / 2); //p_t2_ sprite texture

The sprite also scaled i don't know what is has to do with origin i just went through some post,

[Hapax]

To set the origin to the centre of the sprite:

sf::Vector2f spriteSize{ sprite.getLocalBounds().width, sprite.getLocalBounds().height };
sprite.setOrigin(sprite.getSize() / 2.f);

This means that when you set the sprite's position, its centre will be placed at that position (instead of the default top-left corner).
