调整大小时碰撞不起作用

Question

似乎当我调整碰撞对象的大小时，左，右，底部，顶部是错误的并被推或者什么的。但是绘制的对象距离＆＃34;边界框<＃34;

有点远

我已经研究了几天的碰撞和实施，我已经改进了，但仍然遇到了那些烦人的问题。

我怎样才能解决这个问题？

详细解释会对我有所帮助，如果可以，请告诉我它为什么会这样：

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

    public:

        Player(sf::Vector2f position, sf::Color color){
            rect.setPosition(position);
            rect.setFillColor(color);
        }

        void update(){
            bottom = rect.getPosition().y + rect.getSize().y;
            left = rect.getPosition().x;
            right = rect.getPosition().x + rect.getSize().x;
            top = rect.getPosition().y;    
        }

        bool collision(Player p){
            if(right < p.left || left > p.right || top > p.bottom || bottom < p.top)
