如何检测鼠标和精灵之间的碰撞/鼠标悬停？

Question

目标：知道什么时候一个精灵点击/主动用鼠标

使用：Python的3.2 64位，pygame的1.92 64位，64位Windows 7

我花了6个小时无果......我尝试：

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()) 

我也试着转动鼠标的位置，我真的不想做，就像是有人在这里提到的其他在另一个岗位，为雪碧和碰撞一样，具有相同的结果; （

我能够succ essfully鼠标与图像相撞，但只要我把图像变成一个精灵类，它就成了一场噩梦......精灵类有什么问题？或者我是在浪费时间试图使用精灵来制作漂亮的碰撞特征，而只是使用rect碰撞的图像呢？

保持于获取AttributeError的： '谢尔顿' 对象没有属性 '矩形'（s.Rect.collidepoint） 或AttributeError的： '元组' 对象没有属性 'collidepoint'（s.collidepoint） 或AttributeError的： 'Rake'对象没有属性'sprite'（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，或者我使用错误的事件轮询？

我没有打扰试图重新编码鼠标按下/上/拖动，因为我甚至无法获得鼠标悬停到

希望这一次的工作后得到一个工作响应......别人没“T;（

感谢您的帮助

Answer 1

你不需要Sprite_Mouse_Location。

BTW：设置位置，你需要

rake.rect.topleft = (400, 250) 

# or 

rake.rect.x = 400 
rake.rect.y = 250 

不

rake.rect = (400, 250) 

，因为它与tuple

示例代码替换pygame.Rect()：

我使用Surface而不是image.load()，因此每个人都可以在没有图像的情况下运行它。

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()

有很多的事情，与你的代码怎么回事编码可以在冷杉很难。吨，但要坚持！只要你不断尝试，不要放弃，你会更好！你的错误发生是因为循环上面，你正在设置你的各种精灵的矩形变量为元组而不是矩形。 Rects不是元组，它们有一些元组没有的变量，而collide_rect需要一些变量。我在下面的代码中提出了一些关于其他问题的评论。

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() 

我也建议通过pygame tutorial会以及看其他人的pygame的代码，并试图逐行理解。这些提示都帮助我。祝你好运。

感谢alanxoc3，新的一天，代码在这里工作 发帖，因为我敢肯定，另一个新手会想要做这种类型的点击鼠标
