파이썬 기초 활용 :: 유성피하기 게임 만들기 #우주선에서 미사일발사 추가하기

모든 강의 자료 : www.codingnow.co.kr/

이전의 유성피하기 게임( cflab2017.tistory.com/85 )에서 좀더 업그레이드 하여 우주선에서 미사일을 발사하도록하는 기능을 추가해 봅니다.

유성을 그리는 코드를 대부분 재 사용하여 미사일 발사를 처리 하였습니다.

 

유성은 랜덤함수를 사용하여 무작위로 생성되지만

미사을은 키보드의 스페이스바 키를 누를때 생성되도록 하였습니다.

 

자세한 설명은 동영상을 참고해주세요.

 

이전코트에서 주요 추가코드는 다음과 같습니다.

1. 미사일 이미지를 리스트로 생성하기

#5. 미사일 생성
missile = [pygame.image.load('missile.png') for i in range(40)]
recMissile = [None for i in range(len(missile))]
for i in range(len(missile)):
    missile[i] = pygame.transform.scale(missile[i], (20, 20))
    recMissile[i] = missile[i].get_rect()
    recMissile[i].y = -1

2. 미사일을 생성하고 이동시키기

def CheckCollisionMissile():
    global score, isGameOver
    if isGameOver:
        return
    for rec in recStar:
        if rec.y == -1:
            continue
        for recM in recMissile:
            if recM.y == -1:
                continue
            if rec.top < recM.bottom \
                    and recM.top < rec.bottom \
                    and rec.left < recM.right \
                    and recM.left < rec.right:
                rec.y = -1
                recM.y = -1
                score += 10
                # print(rec, recM)
                break            

def makeMissile():
    if isGameOver:
        return
    for i in range(len(missile)):
        if recMissile[i].y == -1:
            recMissile[i].x = recPlayer.x
            recMissile[i].y = recPlayer.y
            break

def moveMissile():
    # makeMissile()
    for i in range(len(missile)):
        if recMissile[i].y == -1:
            continue
        if not isGameOver:
            recMissile[i].y -= 1
        if recMissile[i].y < 0:
            recMissile[i].y = -1
        SCREEN.blit(missile[i], recMissile[i])
