Python 按X键随机移动玩家

我是一名业余程序员，对Pygame非常陌生。这是我用Pygame编写的程序，类似于Minecraft。在过去的一个小时里，我一直在尝试设置一个代码，使我的播放器在按X键时移动到一个随机平铺。我已经用尽了大部分，如果不是所有的网站和搜索引擎寻找。我已经设法完成了一半的任务；当按下X键时，化身移动到一个随机平铺，但它会移出窗口/显示器。请看一下我的代码，看看我能做些什么来改进它

import pygame, sys, random

LTBLUE = (125, 221, 255)
GREEN = (42, 106, 24)
YELLOW = (247, 243, 59)

WHITE = (255, 255, 255)
PINK = (251, 175, 224)


WATER = 0
SEAWEED = 1
SAND = 2
ROCKS = 3
PEARL = 4
CORAL = 5

PLAYER = pygame.image.load("mermaid.gif")
playerPos=[0,0]


#colors = {SAND: YELLOW, SEAWEED: GREEN, WATER: LTBLUE,  PEARL: WHITE, ROCKS: GREY, CORAL: PINK}

textures = { WATER: pygame.image.load("water.png"),
             SEAWEED: pygame.image.load("seaweed.png"),
             SAND: pygame.image.load("sand.png"),

        myrow=[]

            else:
                randomindex = random.randint(0,5)
                myrow.append(randomindex);

DISPLAYSURF = pygame.display.set_mode((MAPWIDTH*TILESIZE, MAPHEIGHT*TILESIZE))
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        if event.type == KEYDOWN:
                #rmove = random.randint(0,15)
                if event.key == K_RIGHT:
                        playerPos[0]+=1
                elif event.key == K_LEFT:
                        playerPos[0]-=1
                elif event.key == K_UP:
                        playerPos[1]-=1
                elif event.key == K_DOWN:
                        playerPos[1]+=1
                elif event.key == K_x:
                        if(movex<14 and movey<14):
                                playerPos[0]-=movex
                                playerPos[0]+=movex
                                playerPos[1]-=movey
                                playerPos[1]+=movey




    for row in range(MAPHEIGHT):
        for column in range(MAPWIDTH):
           DISPLAYSURF.blit(textures[tilemap[row][column]],(column*TILESIZE, row*TILESIZE))
           DISPLAYSURF.blit(PLAYER, (playerPos[0]*TILESIZE, playerPos[1]*TILESIZE))`

  pygame.display.update()

我认为您在x事件后遗漏了一小部分代码，比如：

movex = random.randint(0,14)
movey = random.randint(0,14)

无论如何，就我理解你的问题而言，假设movex和movey是0到14之间的随机数，问题应该在这里：

if(movex<14 and movey<14):
    playerPos[0]-=movex
    playerPos[0]+=movex
    playerPos[1]-=movey
    playerPos[1]+=movey

你应该能把其余的分类放在一起

附言

为了更清楚，您需要指定一个从0到14的数字，而不是对当前位置进行减法/加法。

在移动玩家之前，使用if检查新位置。

if event.key == K_RIGHT:
    if playerPos[14] == 14:
        playerPos[0]= playerPos[0]
    else:
        playerPos[0]+=1

if event.key == K_LEFT:
    if playerPos[0] == 0:
        playerPos[0]= playerPos[0]
    else:
        playerPos[0]-=1
