Question

그래서 간단한 공간 게임을 만들기 위해 SFML과 C++을 사용하고 있습니다. 생명의 탄생을 위해서는 총알을 얻을 수 없습니다. 이것은 내 소스입니다 ... 난 그냥 게임에 새로운 스프라이트를 산란하는 방법에 대해 배우려고 노력하고 있습니다.

sf::Texture texture_fire; 
if (!texture_background.loadFromFile("fire_1.png")) 

는 texture_background 다시로드 texture_fire합니다. 다음과 같아야합니다.

if (!texture_fire.loadFromFile("fire_1.png"))
