我正在制作一个非常简单的游戏,其中鸟(玩家)必须躲避岩石,如果它被岩石击中,你就输了。我试图使用pygame.sprite.collide_rect()来判断它们是否触及,但我似乎无法确定如何正确使用它。
这是我的代码:
import pygame
import os, sys
import random
import time
img_path = os.path.join('C:\Python27', 'player.png')
img_path2 = os.path.join('C:\Python27', 'rock.png')
class Bird(object):
def __init__(self):
self.image_s = pygame.image.load(img_path)
self.image_b = self.image_s.get_rect()
self.x = 0
self.y = 0
def handle_keys(self):
key = pygame.key.get_pressed()
dist = 2
if key[pygame.K_DOWN]:
self.y += dist
elif key[pygame.K_UP]:
self.y -= dist
if key[pygame.K_RIGHT]:
self.x += dist
elif key[pygame.K_LEFT]:
self.x -= dist
def draw(self, surface):
surface.blit(self.image, (self.x, self.y))
def background(self, surface):
bg = os.path.join('C:\Python27', 'bg.png')
self.image2 = pygame.image.load(bg)
surface.blit(self.image2, (0,0))
class Rock(object):
def __init__(self, x=640, y=0,):
self.image_s = pygame.image.load(img_path2)
self.image_b = self.image_s.get_rect()
self.x = x
self.y = y
dist = 10
self.dist = dist
def rock(self):
dist = 10
self.x -=dist
def rock_draw(self, surface):
surface.blit(self.image, (self.x, self.y))
def checkCollision(sprite1, sprite2):
col = pygame.sprite.collide_rect(sprite1, sprite2)
if col == True:
sys.exit()
pygame.init()
screen = pygame.display.set_mode((640, 200))
bird = Bird()
rock = Rock()
clock = pygame.time.Clock()
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
running = False
if rock.x < 0:
y = random.randint(10, 190)
rock = Rock(640, y)
rock.checkCollision(bird.image_b, rock.image_b)
bird.handle_keys()
rock.rock()
screen.fill((255,255,255))
bird.background(screen)
bird.draw(screen)
rock.rock_draw(screen)
pygame.display.update()
clock.tick(40)
当我尝试运行它时,它告诉我它只需要2个参数,当我尝试修复时我给了3个,我得到了各种不同的错误信息。
答案 0 :(得分:6)
def checkCollision(sprite1, sprite2):
col = pygame.sprite.collide_rect(sprite1, sprite2)
if col == True:
sys.exit()
应该是
def checkCollision(self, sprite1, sprite2):
col = pygame.sprite.collide_rect(sprite1, sprite2)
if col == True:
sys.exit()
因为它是绑定到对象的方法。

你有这个:
col = pygame.sprite.collide_rect(sprite1, sprite2)
但更简单的方法是简单地使用colliderect,这是rect的一个功能。尝试这个可能更容易:
col=sprite1.rect.colliderect(sprite2.rect)

更改
def checkCollision(sprite1, sprite2):
要
def checkCollision(self, sprite1, sprite2):
并且您不必检查每个事件的碰撞,将rock.checkCollision(bird.image_b, rock.image_b)
的缩进减少1。
