为什么我的 rects(bases) 发生碰撞，但它们不在 pygame 窗口中？

如何解决为什么我的 rects(bases) 发生碰撞，但它们不在 pygame 窗口中？

我使用 pygame.rect.collidedirect 来确保没有任何矩形发生碰撞。当我运行它时，它在终端中显示是，这意味着 rects 正在发生冲突，但我无法弄清楚它们在哪里发生冲突，但是在 pyagme 窗口中，一切都是完美的。

import pygame
from random import randint
pygame.init()

screen = pygame.display.set_mode((350,675))
pygame.display.set_caption("First Game")

x_poss = randint(0,350)
y_poss = randint(0,675)
width = 20
height = 20
vel = 8

bases = []

red = (255,0)

image_1 = pygame.image.load('bird.png').convert_alpha()
image_2 = pygame.image.load('base.png').convert_alpha()
image_3 = pygame.image.load('base2.png').convert_alpha()
image_4 = pygame.image.load('enemy.png').convert_alpha()

isJump = False
jumpCount = 10
run = True

def draw_rect(color,x,y,width,height):
    pygame.draw.rect(screen,color,(x,height))

for i in range(5):
    bases.append(pygame.draw.rect(screen,(255,255,255),(randint(0,330),randint(0,675),height)))
    bases.append(pygame.draw.rect(screen,height)))


while run:
    pygame.time.delay(50)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    key = pygame.key.get_pressed()

    if key[pygame.K_LEFT] and x_poss > vel - width:
        x_poss -= vel

    if key[pygame.K_RIGHT] and x_poss < 350 - vel - width:
        x_poss += vel

    if not(isJump):
        if key[pygame.K_UP] and y_poss > vel:
            y_poss -= vel

        if key[pygame.K_DOWN] and y_poss < 670 - height - vel:
            y_poss += vel

        if key[pygame.K_SPACE]:
            isJump = True
    else:
        if jumpCount >= -10:
            y_poss -= (jumpCount * abs(jumpCount)) * 0.5
            jumpCount -= 1
        else:
            jumpCount = 10
            isJump = False

    screen.fill((255,255))


    for base_1 in bases[:5]:
        screen.blit(image_2,base_1)
    for base_2 in bases[5:]:
        screen.blit(image_3,base_2)
    #Here is the problem......
    for base_2 in bases:
        for base_1 in bases:
            if base_1.colliderect(base_2):
                print('yes')
    #till here i think so....
    

    draw_rect((0,0),300,440,10,10)
    draw_rect((255,x_poss,y_poss,height)

    screen.blit(image_4,pygame.draw.rect(screen,(0,(300,10)))
    screen.blit(image_1,(x_poss,height)))
    pygame.display.update()

pygame.quit()

解决方法

矩形与自身发生碰撞。您必须确保 import json import pprint pp = pprint.PrettyPrinter(indent=4) mydata = [] lines = log.split("\n") for line in lines: if line.startswith("DEBUG: {"): json_string = line.split("DEBUG: ")[1] mydata.append(json.loads(json_string)) pp.pprint(mydata) :

base_1 != base_2

碰撞测试可以进一步优化：

for base_2 in bases:
    for base_1 in bases:
        if base_1 != base_2 and if base_1.colliderect(base_2):
            print('yes')

并通过使用 collidelist() 进行简化：

for i,base_2 in enumerate(bases):
    for base_1 in bases[i+1:]:
        if base_1.colliderect(base_2):
            print('yes')
