我試圖制作一個游戲，你可以砍掉一些樹并賣掉它，但在這樣做的過程中我設法發現了一個令人心碎的錯誤——第一棵樹會倒轉所有其他樹！我知道這沒有意義，但我的意思是我已經將樹分類到一個類中，并且我創建了一個名為的變量實例self.tree_property，它確定樹是否已被砍伐。當您砍倒第一棵樹時，所有其他樹都會重新tree_property設置True。當您砍倒任何其他樹時，第一棵樹tree_property會True再次設置為 任何人都可以告訴我如何修復它以及為什么會這樣嗎？代碼如下：import pygameimport timepygame.init()print('Loading game...')icon = pygame.image.load('C:\Program Files\Foraging Simulator\icon.png')market = pygame.image.load('C:\Program Files\Foraging Simulator\market.png')house = pygame.image.load('C:\Program Files\Foraging Simulator\house.png')pygame.display.set_icon(icon)market = pygame.transform.scale(market, (100, 100))house = pygame.transform.scale(house, (100, 100))root = pygame.display.set_mode((603, 573))pygame.display.set_caption("Foraging Simulator")window_is_open = Truewhite = (255, 255, 255)black = (0, 0, 0)width = 10leaves_width = 30height = 20leaves_height = 10x = 0tree_trunk_x = 10y = 0tree_trunk_y = 10vel = 5brown = (150, 75, 0)green = (58, 95, 11)grass = (124, 252, 0)score = 0chop_wood = 'C:\Program Files\Foraging Simulator\chopping.mp3'clock = pygame.time.Clock()time = 0happiness = 10def test(string): print(string)def reset_trees(): for tree in trees: tree.tree_property = Truedef open_house(): reset_trees() score = 0def open_market(): happiness = score / 2class Tree: # The class for the trees def __init__(self, tree_x, tree_y): self.tree_x = tree_x self.tree_y = tree_y self.tree_property = True # Creating instance tree_property self.trunk = None self.leaves = None def destroy(self): self.tree_property = False def create_tree(self): if self.tree_property: trunk_x = self.tree_x + 10 trunk_y = self.tree_y + 10 self.trunk = pygame.draw.rect(root, brown, (trunk_x, trunk_y, width, height)) self.leaves = pygame.draw.rect(root, green, (self.tree_x, self.tree_y, leaves_width, leaves_height))

對象沒有pygame.Surface位置。返回的矩形的位置get_rect()總是 (0, 0)。
請注意，當表面為 時，您指定一個位置blit：
root.blit(house, (400, 100))
當您檢索碰撞的矩形時，您必須設置相同的位置。您可以將關鍵字參數值傳遞給此函數，這些值設置為pygame.Rect對象：
house.get_rect(topleft = (400, 100))
例如：
while window_is_open:
# [...]
for event in pygame.event.get():
if event.type == pygame.QUIT:
window_is_open = False
if event.type == pygame.MOUSEBUTTONDOWN:
mouse_x, mouse_y = event.pos
dx = mouse_x - x
dy = mouse_y - y
if market.get_rect(topleft = (400, 300)).collidepoint(mouse_x, mouse_y):
if abs(dx) <= 50 and abs(dy) <= 50:
open_market()
if house.get_rect(topleft = (400, 100)).collidepoint(mouse_x, mouse_y):
if abs(dx) <= 50 and abs(dy) <= 50:
open_house()
for tree in trees:
if tree.trunk.collidepoint(mouse_x, mouse_y):
if abs(dx) <= 50 and abs(dy) <= 50:
countdown = 3
destroy_tree = tree
# [...]
此外，您必須在函數中使用global語句將其happiness視為全局命名空間中的變量open_market：
def open_market():
global happiness
happiness = score / 2
