Question

如何为矩形的所有4个边创建碰撞？示例：如果玩家进入左侧，则无法再向右移动。如果它落在矩形的顶部，它会停止下降等。

我会看看PyGame Rects。具体来说，请查看pygame.Rect.colliderect。

Bellow我已经将代码粘贴到一个非常简单的骨头游戏中，我相信这些游戏概述了你正在寻找的东西。

import pygame

pygame.init()

screen = pygame.display.set_mode((700, 400))
clock = pygame.time.Clock()

BLACK, WHITE, GREY = (0, 0, 0), (255, 255, 255), (100, 100, 100)

block_x, block_y = 25, 175
speed_x, speed_y = 0, 0


run = 1
while run:
    for e in pygame.event.get():
        if e.type == pygame.QUIT:
            run = 0
        if e.type == pygame.KEYDOWN:
            if e.key == pygame.K_LEFT:
                speed_x = -5
                speed_y = 0
            if e.key == pygame.K_RIGHT:
                speed_x = 5
                speed_y = 0
            if e.key == pygame.K_UP:
                speed_x = 0
                speed_y = -5
            if e.key == pygame.K_DOWN:
                speed_x = 0
                speed_y = 5

    screen.fill(BLACK)

    block_x += speed_x
    block_y += speed_y

    blockOne_rect = pygame.Rect(block_x, block_y, 50, 50)
    blockTwo_rect = pygame.Rect(600, 175, 50, 50)

    pygame.draw.rect(screen, WHITE, blockOne_rect)
    pygame.draw.rect(screen, GREY, blockTwo_rect)

    if blockOne_rect.colliderect(blockTwo_rect):
        speed_x = 0
        speed_y = 0


    clock.tick(60)
    pygame.display.update()

pygame.quit()
quit()
