Python Pygame墙精灵碰撞

我正在做一个类似流氓的游戏，但在编码方面我是初学者。我已经有我的角色移动，我的墙和地板精灵，但我的代码中有一些错误，允许角色通过墙移动

screenWidth = 800
screenHeight = 600
mapHeight = 30
mapWidth = 30
cellWidth = 32
cellHeight = 32

screen = pygame.display.set_mode((screenWidth, screenHeight))
walkRight = [pygame.image.load('model/r1.png'), pygame.image.load('model/r2.png'), pygame.image.load('model/r3.png'), pygame.image.load('model/r4.png'), pygame.image.load('model/r5.png'), pygame.image.load('model/r6.png')]
walkLeft = [pygame.image.load('model/l1.png'), pygame.image.load('model/l2.png'), pygame.image.load('model/l3.png'), pygame.image.load('model/l4.png'), pygame.image.load('model/l5.png'), pygame.image.load('model/l6.png')]
walkUp = [pygame.image.load('model/u1.png'), pygame.image.load('model/u2.png'), pygame.image.load('model/u3.png'), pygame.image.load('model/u4.png'), pygame.image.load('model/u5.png'), pygame.image.load('model/u6.png')]
Floor = pygame.image.load("map/floor.jpg")
wallRight = pygame.image.load("map/rightwall.png")

我使用

block_路径

在地板和墙砖之间进行选择，然后我尝试使用它来识别墙壁，但没有真正起作用

screenWidth = 800
screenHeight = 600
mapHeight = 30
mapWidth = 30
cellWidth = 32
cellHeight = 32

screen = pygame.display.set_mode((screenWidth, screenHeight))
walkRight = [pygame.image.load('model/r1.png'), pygame.image.load('model/r2.png'), pygame.image.load('model/r3.png'), pygame.image.load('model/r4.png'), pygame.image.load('model/r5.png'), pygame.image.load('model/r6.png')]
walkLeft = [pygame.image.load('model/l1.png'), pygame.image.load('model/l2.png'), pygame.image.load('model/l3.png'), pygame.image.load('model/l4.png'), pygame.image.load('model/l5.png'), pygame.image.load('model/l6.png')]

将

createmap（）

函数更改为类似的函数将在地图的钻孔器上创建一个5像素的缓冲区。我之所以将其设置为5像素，是因为角色移动就是这样

screenWidth = 800
screenHeight = 600
mapHeight = 30
mapWidth = 30
cellWidth = 32
cellHeight = 32

screen = pygame.display.set_mode((screenWidth, screenHeight))
walkRight = [pygame.image.load('model/r1.png'), pygame.image.load('model/r2.png'), pygame.image.load('model/r3.png'), pygame.image.load('model/r4.png'), pygame.image.load('model/r5.png'), pygame.image.load('model/r6.png')]
walkLeft = [pygame.image.load('model/l1.png'), pygame.image.load('model/l2.png'), pygame.image.load('model/l3.png'), pygame.image.load('model/l4.png'), pygame.image.load('model/l5.png'), pygame.image.load('model/l6.png')]

Floor = pygame.image.load("map/floor.jpg")
wallRight = pygame.image.load("map/rightwall.png")

我建议加入一些实际的角色碰撞来测试你是否超出了边界，不管速度如何

编辑：我已经包含了完整的代码，因为如果我显示它们，我所做的更改更容易理解

Floor = pygame.image.load("map/floor.jpg")
wallRight = pygame.image.load("map/rightwall.png")

我已将您的图像列表更改为dict of list，因为这样更容易调用。您要求的网格为30x30。由于您显示的单元格宽度为32x32，我将贴图更改为960 x 960

screenWidth = 800
screenHeight = 600
mapHeight = 30
mapWidth = 30
cellWidth = 32
cellHeight = 32

walkLeft = [pygame.image.load('model/l1.png'), pygame.image.load('model/l2.png'), pygame.image.load('model/l3.png'), pygame.image.load('model/l4.png'), pygame.image.load('model/l5.png'), pygame.image.load('model/l6.png')]
walkUp = [pygame.image.load('model/u1.png'), pygame.image.load('model/u2.png'), pygame.image.load('model/u3.png'), pygame.image.load('model/u4.png'), pygame.image.load('model/u5.png'), pygame.image.load('model/u6.png')]

wallRight = pygame.image.load("map/rightwall.png")

我扩展了你的移动方法来检查冲突，看看它是否能在移动之前移动。我还删除了你的

redraw（）

函数，因为它更容易向下移动你的redraw。如果你愿意，你可以将它添加回，但在本例中，我删除了它
