온라인에서 찾은 파이게임 실행해 보고 있었는데 이해가 잘 안가는 코드가 있어서요.
중간중간 moveSpeed가 어떻게 숫자(?)처럼 쓰였는지 잘 이해가 가지 않습니다.
self.moveSpeed = moveSpeed 이런식으로 정의되지도 않았는데 말이죠.
예를 들면
def move(self, moveSpeed):
self.x -= moveSpeed
이런 부분이요.
class HurdleManager:
def __init__(self, scale, spawnRange):
self.img = transform.scale(image.load('homework.png'), (7 * scale, 15 * scale))
self.spawnRange = spawnRange
self.hurdleList = []
self.scale = scale
def update(self, doSpawn, moveSpeed):
if doSpawn:
self.spawn()
self.manage(moveSpeed)
def manage(self, moveSpeed):
hurdles2 = []
for hurdle in self.hurdleList:
hurdle.update(moveSpeed)
if hurdle.onScreen():
hurdles2.append(hurdle)
self.hurdleList = hurdles2
spawnTick = 0
def spawn(self):
if self.spawnTick >= self.spawnRange[1]:
newHurdle = HurdleClass(windowX, self.img, 7 * self.scale, 15 * self.scale)
self.hurdleList.append(newHurdle)
self.spawnTick = 0
elif self.spawnTick > self.spawnRange[0]:
if random.randint(0, self.spawnRange[1] - self.spawnRange[0]) == 0:
newHurdle = HurdleClass(windowX, self.img, 7 * self.scale, 15 * self.scale)
self.hurdleList.append(newHurdle)
self.spawnTick = 0
self.spawnTick += 1
hurdleManager = HurdleManager(3, (45, 90))
class HurdleClass:
def __init__(self, x, img, width, height):
self.x = x
self.img = img
self.width = width
self.height = height
self.y = ground - height
def update(self, moveSpeed):
self.move(moveSpeed)
self.show()
