我正在創建一個簡單的 python 游戲，在其中，一個角色四處移動以收集物品。我創建了四處移動的角色，當他們經過一個項目（圖像）時，會彈出文本詢問他們是否要拿起該項目以及說“是”和“否”的按鈕。如果他們點擊是，該項目應該消失，然后他們返回游戲。如果他們單擊否，該項目將保留在那里，他們應該返回游戲。為了擺脫這個項目，我試圖在沒有他們收集的項目的情況下重新繪制屏幕。但是，我不知道點擊是或否后如何返回游戲。如果按鈕功能將它們返回到，game_loop()則該redrawGameWindow()功能將激活，將角色移回其起始位置并返回項目。有誰知道如何解決這個問題/在我的按鈕中放置什么功能？謝謝！

我會這樣做的方法是為一個對象創建一個類，然后創建對象并將它們放在一個列表中，當你繪制窗口時，循環遍歷列表并繪制每個對象，如果你想“擺脫”一個對象，將其從列表中刪除，如果要添加對象，將其添加到列表中
這是一個例子
class Object:
def __init__(self, x, y, image):
self.x = x
self.y = y
self.image = image
self.rect = image.get_rect()
self.rect.topleft = (self.x, self.y)
objs = []
objs.append(Object(100, 100, swordIMG))
objs.append(Object(300, 400, staffIMG))
objs.append(Object(200, 340, chestIMG))
def redrawGameWindow():
for obj in objs:
win.blit(obj.image, obj.rect)
def game_loop():
while run:
for obj in reversed(objs): #if delete obj in list while looping through it, the loop will still try to get the deleted obj, so reverse to fix this
if obj.rect.collidpoint((x + vel, y + vel)):
collect_item(obj) #give the object so we know which one to delete
def button(msg,x,y,w,h,ic,ac, action=None, arg = None):
mouse = pygame.mouse.get_pos()
click = pygame.mouse.get_pressed()
pygame.draw.rect(win, ic, (x,y,w,h))
#print(mouse)
if x + w > mouse[0] > x and y+h > mouse[1] > y:
pygame.draw.rect(win, ac, (x,y,w,h))
if click[0] == 1 and action != None:
if arg:
action(arg)
else:
action()
else:
pygame.draw.rect(win, ic, (x,y,w,h))
smallText = pygame.font.Font("Gameplay.ttf", 20)
textSurf, textRect = text_objects(msg, smallText)
textRect.center = ((x+(w/2), y+(h/2)))
win.blit(textSurf, textRect)
def collect_items(obj):
button("YES",150,450,100,50,green, bright_green, remove_image,obj)
button("NO",550,450,100, 50, red, bright_red)
message_display('Do you want to pick up item?')
def remove_image(obj):
del objs[objs.index(obj)]
按鈕功能看起來不錯，我最近嘗試在這里為 pygame 制作一個可自定義但簡單的按鈕，如果你想要一些靈感的話

這段代碼有效，我發現你在文本顯示中有 time.sleep 所以 fps 下降到每秒半幀，但是一旦它出來并且我移動了繪圖的順序，一切似乎都有效，我沒有圖像你有所以我把它們改成了正方形，它們在頂部，不要復制粘貼它們
