SDL_Rect draw bug (bullet.cpp)

#include "Bullet.h"

Bullet::Bullet(int x, int y, int xvel, int yvel) : Entity((SDL_Rect) {x, y, 5, 5}) {
    setXVel(xvel);
    setYVel(yvel);
}

void Bullet::render(SDL_Surface* surface) {
    SDL_Rect bounds = getBounds();
    SDL_FillRect(surface, &bounds, SDL_MapRGB(surface->format, 255, 0, 0));
}
