目标：了解何时使用鼠标点击/激活精灵
使用：Python 3.2 64bit，Pygame 1.92 64bit，windows 7 64bit
我花了6个小时无济于事......我已经尝试过了：
s.rect.collidepoint(pygame.mouse.get_pos())
s.collidepoint(pygame.mouse.get_pos())
s.sprite.spritecollide(pygame.mouse.get_pos())
s.spritecollide(pygame.mouse.get_pos())
s.sprite.collide_rect(pygame.mouse.get_pos())
s.collide_rect(pygame.mouse.get_pos())
我也尝试将鼠标位置转换为精灵，我真的不想这样做，就像其他帖子中提到的其他人一样，进入一个精灵，然后碰撞出相同的结果;（< / p>
我能够成功地与图像发生碰撞，但是一旦我将图像转换为精灵类，它就变成了一场噩梦......精灵课有什么问题？或者我是否在浪费时间尝试使用精灵来获得漂亮的碰撞功能，而只是使用直接碰撞的图像？
继续获取AttributeError：＆＃39; Sheldon＆＃39;对象没有属性＆＃39; Rect＆＃39; （s.Rect.collidepoint） 或AttributeError：＆＃39;元组＆＃39;对象没有属性＆＃39; collidepoint＆＃39; （s.collidepoint） 或者属性错误：＆＃39; Rake＆＃39;对象没有属性＆＃39; sprite＆＃39; （s.sprite.collidepoint）
由于我是python / pygame的新手，我应该将这个检测放在sprite类本身的Update / Render方法中，还是我使用错误的事件轮询???
我还没有想过要重新编码mousedown / up / dragging，因为我甚至无法让鼠标移动工作
希望这次帖子得到一个有效的回应...其他人没有;（
感谢您的帮助。

您的代码有很多事情要发生。编码起初可能很难，但要坚持下去！只要你继续努力并且不放弃，你就会变得更好！您的错误正在发生，因为在循环之上，您正在设置各种精灵＆＃39;将变量转换为元组而不是rects 。 Rect不是元组，它们有一堆变量，元组不具备，而collide_rect需要其中的一些变量。我在下面的代码中对您的其他问题提出了一些意见。
import pygame
from pygame import *
from pygame.locals import *
from pygame.sprite import *
class Sheldon(Sprite):
def __init__(self):
Sprite.__init__(self)
self.image = transform.scale(image.load('sheldon.jpg').convert(),(230,310))
self.rect = self.image.get_rect()
class Rake(Sprite):
def __init__(self):
Sprite.__init__(self)
self.image = transform.scale(image.load('rake.jpg').convert(),(230,310))
self.rect = self.image.get_rect()
class Sprite_Mouse_Location(Sprite):
def __init__(self,x,y):
Sprite.__init__(self)
self.rect = pygame.Rect(x,y,1,1)
print(self.rect)
pygame.init()
window = display.set_mode( (800,600) )
sheldon = Sheldon()
sheldon.rect = (10,10) # (10,10) is not a rect!
# pygame.Rect(0,0,10,10) is a rect!
all_sprites = Group(sheldon)
rake = Rake()
rake.rect = (400,250) # Same as above comment.
all_sprites.add(rake)
x,y = pygame.mouse.get_pos() # If you are going to make the mouse
mouse_sprite = Sprite_Mouse_Location(x,y) # a sprite, then update your mouse position in the loop.
running = True
while running == True:
for event in pygame.event.get():
if event.type == QUIT or event.type == KEYUP and event.key == K_ESCAPE :
pygame.quit()
elif event.type == MOUSEMOTION :
# You could have this instead.
# mouse_sprite.rect.x, mouse_sprite.rect.y = pygame.mouse.get_pos()
# Then move the for loop below to be out of the event loop.
for s in all_sprites :
if pygame.sprite.collide_rect(s,mouse_sprite):
print("hit")
window.fill( (0,0,0) )
all_sprites.update()
all_sprites.draw(window)
display.update()
我还建议您浏览pygame tutorial以及查看其他人的pygame代码并尝试逐行理解。这些提示都帮助了我。祝你好运。

感谢alanxoc3和新的一天，代码正常运行 发布在这里，因为我确定另一个新手想要做这种类型的鼠标点击
# to create a group of sprites and use the mouse over them individually
import pygame

self.rect = self.image.get_rect()

您不需要Sprite_Mouse_Location。
BTW：设置你需要的位置
rake.rect.topleft = (400, 250)
# or
rake.rect.x = 400
rake.rect.y = 250
不是
rake.rect = (400, 250)
因为它将pygame.Rect()替换为tuple
示例代码：
我使用Surface代替image.load()，因此每个人都可以在没有图片的情况下运行它。
import pygame
# --- constants --- (UPPER_CASE names)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
# --- classes --- (CamelCase names)
class Sheldon(pygame.sprite.Sprite):
def __init__(self, x, y):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.Surface((230, 310))
self.image.fill(RED)
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
def check_click(self, mouse):
if self.rect.collidepoint(mouse):
print("hit RED")
class Rake(pygame.sprite.Sprite):
def __init__(self, x, y):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.Surface((230, 310))
self.image.fill(GREEN)
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
def check_click(self, mouse):
if self.rect.collidepoint(mouse):
print("hit GREEN")
# --- main --- (lower_case names)
# - init -
pygame.init()
window = pygame.display.set_mode((800,600))
# - objects -
sheldon = Sheldon(10, 10)
#sheldon.rect.topleft = (10, 10)
rake = Rake(400, 250)
#rake.rect.topleft = (400, 250)
all_sprites = pygame.sprite.Group()
all_sprites.add(sheldon, rake)
# - mainloop -
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT or \
(event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE):
running = False
elif event.type == pygame.MOUSEBUTTONDOWN:
for s in all_sprites:
s.check_click(event.pos)
window.fill(BLACK)
all_sprites.update()
all_sprites.draw(window)
pygame.display.update()
# - end -
pygame.quit()
