Question

希望你能帮助我，过去几天我一直在努力解决这个问题。我想做一个坚实的＆＃34;阻止我正在进行的我的2d平台游戏，但是当我进入那个＆＃34;固体＆＃34;阻止我传送到另一侧或块的底部，我不知道为什么，希望你知道为什么所以这是我的代码：

class Block(pygame.sprite.Sprite):

    def __init__(self, color = blue,widht = 64, height = 64):

        super(Block, self).__init__()

        self.image = pygame.Surface((widht, height))
        self.image.fill(color)
        self.rect = self.image.get_rect()

        self.sound = pygame.mixer.Sound("2dSounds/Walk.wav")

        self.hspeed = 0
        self.vspeed = 0
    def update(self, collidable):
        self.rect.x += self.hspeed

        collision_list = pygame.sprite.spritecollide(self, collidable, False)
        for collided_object in collision_list:
            if (self.hspeed > 0):
                # right direction
                self.rect.right = collided_object.rect.left

            elif (self.hspeed < 0):
                # left direction
                self.rect.left = collided_object.rect.right

        self.rect.y += self.vspeed

        collision_list = pygame.sprite.spritecollide(self, collidable, False)   
        for collided_object in collision_list:
            if (self.vspeed > 0):
             # down direction
                self.rect.bottom = collided_object.rect.top

            elif (self.vspeed < 0):
                # up direction
                self.rect.top = collided_object.rect.bottom
    def change_speed(self, hspeed, vspeed):
        self.hspeed += hspeed
        self.vspeed += vspeed
    def set_position(self, x, y):
        self.rect.x = x 
        self.rect.y = y

非常感谢！：）

很抱歉，我的代码并非基于您的代码，我在过去的5分钟里只是把它放在一起，所以它不是很漂亮，但这里是：< / p>

from pygame.locals import *

import pygame
import sys

GRAVITY = 1.2

class Player:
    def __init__(self, x, y):
        self.rect = pygame.Rect(x, y, 25, 25)
        self.yvel = 0

    def tick(self):
        self.yvel += GRAVITY

        self.rect.y += int(self.yvel)

        if self.rect.y >= 475:
            self.rect.y = 475
            self.yvel = 0

    def set(self, y):
        if y:
            self.yvel = y

class Block:
    def __init__(self, x, y, w, h):
        self.rect = pygame.Rect(x, y, w, h)

class Game:
    def __init__(self):
        pygame.init()
        self.screen = pygame.display.set_mode((500, 500))
        self.player = Player(0, 0)
        self.block = Block(225, 400, 50, 50)

    def main(self):
        right = left = False
        while True:
            self.screen.fill((230, 230, 230))
            pygame.draw.rect(self.screen, (40, 40, 40), self.block.rect)
            pygame.draw.rect(self.screen, (100, 200, 100), self.player.rect)

            pygame.display.flip()
            for event in pygame.event.get():
                if event.type == QUIT:
                    pygame.quit()
                    sys.exit(0)
                elif event.type == KEYDOWN:
                    if event.key == K_SPACE:
                        self.player.set(-20)
                    elif event.key == K_RIGHT:
                        right = True
                    elif event.key == K_LEFT:
                        left = True
                elif event.type == KEYUP:
                    if event.key == K_RIGHT:
                        right = False
                    elif event.key == K_LEFT:
                        left = False

            if right:
                self.player.rect.x += 5
                while self.player.rect.colliderect(self.block.rect):
                    self.player.rect.x -= 1
            if left:
                self.player.rect.x -= 5
                while self.player.rect.colliderect(self.block.rect):
                    self.player.rect.x += 1
            self.player.tick()
            if self.player.yvel > 0:
                while self.player.rect.colliderect(self.block.rect):
                    self.player.rect.y -= 1
                    self.player.yvel = 0
            elif self.player.yvel < 0:
                while self.player.rect.colliderect(self.block.rect):
                    self.player.rect.y += 1
                    self.player.yvel = 0

game = Game()
game.main()

播放器速度非常快，但可以在以下行改变：

self.player.rect.x -= 5

和

self.player.rect.x += 5

靠近底部。

它的工作方式是每当你移动时，它会移动玩家，然后查看是否与该块相撞。如果是这样，则玩家向相反方向移动，直到确信它不再发生碰撞为止。跳跃是使用速度完成的，因此Player.yvel和GRAVITY。可以更改GRAVITY但如果更高，则跳转会更短，反之亦然。

玩弄代码并尝试阻止位置（self.block = Block(225, 400, 50, 50)）和玩家的凝视位置（self.player = Player(0, 0)）之类的东西

如果您在代码中发现任何错误，请告诉我，我会尝试修复它们。

试图做一个坚实的＆＃34;阻止pygame但它不起作用
