【问题描述】:
您好,我是一个 python 菜鸟,我正在尝试自己用 pygame 制作一个刽子手游戏,同时尽可能避免从 YouTube 教程中获得帮助。
我的问题是:
-
当我将鼠标悬停在按钮上时,按钮会改变颜色(这很好),但即使我仍然将鼠标悬停在按钮上,它也会变回来。此外,当鼠标悬停在多个按钮上时,按钮的响应性非常差。
-
当我单击一个按钮时,程序认为我多次单击该按钮。因为它多次执行
print('clicked!')行。 -
最后,当我单击一个按钮来对精灵进行 blit 时,它只会在短时间内对 sprite 进行 blit,然后它会自动取消 blit。
这是我的代码:
import pygame
pygame.init()
# DISPLAY
WIDTH, HEIGHT = 800, 500
window = pygame.display.set_mode((WIDTH, HEIGHT))
# TITLE BAR
TITLE = "Hangman"
pygame.display.set_caption(TITLE)
# HANGMAN SPRITES
man = [pygame.image.load(f"hangman{frame}.png") for frame in range(0, 7)]
class Button:
def __init__(self, color, x, y, radius, text=""):
self.radius = radius
self.color = color
self.x = x
self.y = y
self.width = 2
self.text = text
self.visible = True
def draw(self, window, outline=None):
if self.visible:
if outline:
# draws a bigger circle behind
pygame.draw.circle(window, outline, (self.x, self.y), self.radius + 2, 0)
pygame.draw.circle(window, self.color, (self.x, self.y), self.radius, 0)
if self.text != "":
if self.visible:
font = pygame.font.SysFont("courier", 30)
text = font.render(self.text, 1, (0, 0, 0))
window.blit(text, (self.x - text.get_width() / 2, self.y - text.get_height() / 2))
def hover(self, pos):
if self.y + self.radius > pos[1] > self.y - self.radius:
if self.x + self.radius > pos[0] > self.x - self.radius:
return True
return False
def main():
run = True
FPS = 60
clock = pygame.time.Clock()
large_font = pygame.font.SysFont("courier", 50)
letters = []
error = 0
def redraw_window():
window.fill((255, 255, 255))
window.blit(man[0], (20, 100))
# DRAWS LETTER BUTTONS
for letter in letters:
letter.draw(window, (0, 0, 0))
pygame.display.update()
while run:
redraw_window()
clock.tick(FPS)
alphabet = list("ABCDEFGHIJKLMNOPQRSTUVWXYZ")
letter_x1, letter_y1 = 40, 375
letter_x2, letter_y2 = 40, 435
for i in range(13):
letter_1 = Button((255, 255, 255), letter_x1, letter_y1, 25, alphabet[i])
letters.append(letter_1)
letter_x1 += 60
for i in range(13, 26):
letter_2 = Button((255, 255, 255), letter_x2, letter_y2, 25, alphabet[i])
letters.append(letter_2)
letter_x2 += 60
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
elif event.type == pygame.MOUSEMOTION:
for letter in letters[:]:
if letter.hover(pygame.mouse.get_pos()):
letter.color = (0, 255, 0)
else:
letter.color = (255, 255, 255)
elif event.type == pygame.MOUSEBUTTONDOWN:
for letter in letters:
if letter.hover(pygame.mouse.get_pos()):
print("clicked!")
window.blit(man[1], (20, 100))
pygame.display.update()
quit()
main()
另外,我从 YouTube 上的 Tim Hangman 技术教程中获得了精灵(我只是在没有看他编写游戏代码的情况下获得了精灵,因为我想尝试自己做,以便了解更多信息)。我还从 Tech With Tim 的视频中获得了按钮类的代码。
