이 코드는 ASCII 문자를 사용하여 그래픽을 그릴 수 있습니다.

삼각형, 원 모델 들의 도형을 그릴 수 있는 함수도 있습니다.

Sprite 클래스는 이미지를 나타내는 데 사용됩니다. Draw, Fill, DrawString, DrawLine 등의 함수를 사용하여 콘솔에 그래픽을 그릴 수 있습니다.

 

게임 루프는 GameThread 함수에서 실행됩니다. 사용자가 정의한 OnUserCreate, OnUserUpdate, OnUserDestroy 함수가 호출되어 게임의 초기화, 갱신, 종료 작업을 수행합니다.

 

키보드 와 마우스 입력을 처리하고 콘솔 창의 타이틀을 업데이트하는 역할도 합니다.
