Question

我正在正方形的所有侧面制作一个四人乒乓球，但在如何增加每个单独的桨叶之间的碰撞方面却一无所获，以免它们在拐角处彼此相撞

import pygame
pygame.init()
### Colors
WHITE = (255, 255, 255)
BLACK = (0,0,0)
win = pygame.display.set_mode((500, 500))
pygame.display.set_caption("GNOP")

x = 485
y = 75
x2 = 5
y2 = 75
x3 = 250
y3 = 5
y4 = 485
x4 = 250
width = 10
height = 90
vel = 5

run = True
while run:
    print(x4,y4)
    pygame.time.delay(10)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    key= pygame.key.get_pressed() 
    if key [pygame.K_UP] and y>0:
        y -= vel
    if key [pygame.K_DOWN]and y<420:
        y += vel
    if key [pygame.K_w] and y2>0:
        y2 -= vel
    if key [pygame.K_s]and y2<420:
        y2 += vel
    if key [pygame.K_c] and x3>0:
        x3 -= vel
    if key [pygame.K_v] and x3<420:
        print(1)
        x3 += vel
    if key [pygame.K_n] and x4>0:
        x4 -= vel
    if key [pygame.K_m] and x4<420:
        x4 += vel

def ball (self):
    # Create the image of the ball
    self.image = pygame.Surface([10, 10]) 
    # Color the ball
    self.image.fill(BLACK)

    # Get a rectangle object that shows where our image is
    self.rect = self.image.get_rect()

    # Get attributes for the height/width of the screen
    self.screenheight = pygame.display.get_surface().get_height()
    self.screenwidth = pygame.display.get_surface().get_width()

    # Speed in pixels per cycle
    self.speed = 0

    # Floating point representation of where the ball is
    self.x = 0
    self.y = 0

    # Direction of ball in degrees
    self.direction = 0

    # Height and width of the ball
    self.width = 10
    self.height = 10

    # Set the initial ball speed and position
    self.reset()

win.fill((230,230,230))
pygame.draw.rect(win,(0, 0, 0), (x, y, width, height))
pygame.draw.rect(win,(255,50,0), (x2, y2, width, height))
pygame.draw.rect(win,(150,15,200), (x3, y3, height, width))
pygame.draw.rect(win,(0,100,255), (x4, y4, height, width))
pygame.display.update()
pygame.quit()
ball()

我需要球拍互相检测并碰撞，而不是彼此相撞，但是我已经看过几个代码，但是我还没有学习如何针对每个单独地做到这一点，这很关键，因为我无法拿到球没有它就可以工作

Answer 1

如果要检测碰撞：

def touched(tar_x,tar_y,tarimage,tar_x1,tar_y1,tarimage2):
    for i in range(tar_x1,tar_x1 + tarimage2.get_width()):
        for j in range(tar_y1,tar_y1 + tarimage2.get_height()):
            if tar_x < i < tar_x + tarimage.get_width() and tar_y < j < tar_y + tarimage.get_height():
                return True
    return False

tar_x，tar_y是第一个对象的位置 tar_x1，tar_y1是第二个对象的位置 tarimage，tarimage2是加载到pygame中的图像

我不知道如何为更改后的乒乓代码向桨叶添加碰撞
