화면에 표시되는 개체의 양을 표시합니다.

Question

이 자습서는 다음과 같습니다. http://www.raywenderlich.com/24252/beginning-game-programming-for-teens-with-python#comments 그리고 나는 오소리가 그려지는 부분에서 화면에 그려지는 오소리의 양을 줄이려고합니다. random.randint(50,430)은 50과 430 사이의 수 많은 오소리를 그립니다. 그러나 더 작은 숫자는 5-9 명의 오소리가 화면에 그려지는 것을 원합니다. 나는 또한 오소리가있는 곳의 위치를보고 싶습니다. 그러면 화면의 상단에서오고 왼쪽으로 오지 않습니다. 어떻게해야합니까? 여기

Answer 1

y는 임의의 위치가 위치 (640, Y)와

badguys.append([640, random.randint(50,430)]) 

은 하나의 나쁜 사람을 추가한다이 줄, 50에서 430 사이입니다. 640은 코드에서 "왼쪽"이라고하고 y는 코드에서 "위쪽"이라고합니다. 당신이 그 (것)들을 상단에 표시 할 경우 당신은 또한 당신은 나쁜 사람을해야합니다

badguys.append([random.randint(50,610), 0]) 

을 시도 오른쪽으로 대신 아래로 이동 수도 있지만, 당신은 아마도

badguys.append([random.randint(50,610), 480]) 

를 원한다. 당신은 당신이 적은 나쁜 놈들을 원하는 경우에,

badguy[1] -= 7 

이 줄

badguy[0]-=7 

을 변경 큰를 badtimer하게, 또는 좀 더 천천히 감소합니다.
