OpenGL에서 3 개의 큰 상자와 1 개의 작은 상자가있는 게임을 작성하고 있습니다. 작은 상자는 큰 상자 중 하나에 숨겨져 있으며 사용자는 A, B 또는 C를 눌러 작은 상자의 위치를 표시해야합니다. 사용자가 얼마나 많은 추측을했는지, 진행 한 라운드 수를 추적하고 싶지만 OpenGL에서 증가 된 숫자를 출력하는 방법에 대해서는 잘 모릅니다. 숫자에 관련된 것이 생길 때마다 숫자를 증가시키고 싶지만, 알아낼 수는 없습니다. 누군가 올바른 방향으로 나를 가리킬 수 있습니까? 정말 고맙습니다!OpenGL에서 변수 번호를 출력하는 방법은 무엇입니까?
