我不知道如何添加碰撞到桨为我改变庞鳕鱼

Question

我在广场的四面八方做了一个4人的乒乓球，但是我不知道如何在每个划桨之间增加碰撞，这样他们就不会在角落里相撞了

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()

我需要桨来检测彼此和碰撞，而不是进入另一个阶段，但我看了几个代码，我还没有学会如何为每个人单独，这是至关重要的，因为我不能让球工作没有它

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

taru x，taru 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
