我正在使用 pygame 创建一个 Brick Breaker 游戏。除了碰撞之外，我已经让其他一切都正常工作了。我尝试使用 collide_rect 但它不起作用，但它没有给我错误消息。我尝试使用 spritecollide，但它给了我错误消息 Ball object is not iterable。我的目标是检测方块，将其移除，并提高分数。抱歉，我的代码有点乱。 这是我的代码（碰撞检测位于底部附近）：

这是我的课程示例：
import pygame
class Block(pygame.sprite.Sprite):
def __init__(self, posx, posy, width, height):
pygame.sprite.Sprite.__init__(self)
super().__init__()
#self.rect = self.image.get_rect()
self.rect = pygame.Rect(posx, posy, width, height)
self.posx = posx
self.posy = posy
self.height = height
self.width = width
def draw (self, Display):
pygame.draw.rect(Display, [6,130,183], [self.posx, self.posy, self.width, self.height])
我正在使用 PyCharm 请让我知道该怎么做。 谢谢
问题在于条件
if (ballX >= mouseX or ballX <= mouseX) and (ballX + ballSize <= mouseX + PaddleW/2 and ballX + ballSize >= mouseX - PaddleW/2):
第一个条件 (
(ballX >= mouseX or ballX <= mouseX)True如果您的范围为
x1x1+w1x2x2+w2x1 <= x2+w and x2 <= x1+w1
所以碰撞测试必须是：
if ballY <= PaddleY + PaddleH and PaddleY <= ballY + ballSize:
if ballX <= mouseX + PaddleW/2 and mouseX - PaddleW/2 <= ballX + ballSize:
ballMoveY = -ballMoveY
score += 10
pygame.Rect.colliderect()ball_rect = pygame.Rect(ballX, ballY, ballSize, ballSize)
paddle_rect = pygame.Rect(mouseX-PaddleW/2, PaddleY, PaddleW, PaddleH)
if ball_rect.colliderect(paddle_rect):
ballMoveY = -ballMoveY
score += 10
Sprites.rectclass Ball(pygame.sprite.Sprite):
# [...]
def move(self, x, y):
self.rect.topleft = (x, y)
self.posx, self.posy = self.rect.topleft
class Paddle(pygame.sprite.Sprite):
# [...]
def move(self, x):
self.rect.centerx = x
self.posx = self.rect.left
现在您可以使用对象的
.rectif ball.rect.colliderect(player.rect):
ballMoveY = -ballMoveY
score += 10
pygame.sprite.collide_rect()if pygame.sprite.collide_rect(ball, player):
ballMoveY = -ballMoveY
score += 10
注意，
SpriteGroupGrouppygame.sprite.spritecollide()pygame.sprite.groupcollide()blocks = pygame.sprite.Group()
blocks.add(block.Block(10,block1Y,blockW, blockH, blockColor))
if pygame.sprite.spritecollide(ball, blocks, False):
ballMoveY = -ballMoveY
score += 10
for block in blocks:
