첫 번째로 빠져 나가야 할 것이 있습니다. 미안하지만 (매우) 분명하지 않은 점이 있다면, 나는 아직도 이것에 대해 조금 새로운 것입니다.아주 이상한 조건에서 XNA 게임을 실행하지 마십시오
어쨌든, 나는 XNA에서 소행성 복제본을 작성해 왔으며 어떤 이유로 디버깅 시작 버튼을 누르면 때때로 시작되지 않습니다. 나는 AsteroidsManager 클래스에이 문제를 추적했다.이 클래스는 소행성과 입자에 대한 최소 및 최대 속도와 회전 속도, 그리고 두 개의 텍스처 목록을 생성하기 위해 초기 소행성의 정수를 사용했다. 이제 불확실성 :
temp = new AsteroidManager(1, 20, 50, 1, 2, asteroids, particles, true); //With this constructor, the game always starts fine...
하지만 초기 소행성의 수 크랭크 경우 :
temp = new AsteroidManager(10, 20, 50, 1, 2, asteroids, particles, true); //This seems to start about 1/3 times in the Visual Studio debugger, but if I launch it without debugging or from the bin folder, it works fine.
그리고 이상 ~ 20 소행성을 설정하면 마지막으로, 그것은 결코 디버거에서 시작하지를, 폴더에서 시작하려고하면 프로세스가 작업 관리자에 나타나지만 아무 일도 일어나지 않습니다. 아니면 시작과 동시에 충돌합니다. 솔직히이 원인이 무슨 생각이 없으며, 필요하다면 기꺼이 코드를 제공하지만 여기에 내가 관련되어 있다고 생각하는 내용은 다음과 같습니다
