你如何让一个物体在一个区域内随机移动？

如何解决你如何让一个物体在一个区域内随机移动？

我在 pygame 中将 4 个僵尸传送到屏幕上。僵尸需要在他们被 blit 的地方周围的特定区域（让我们说 10 x 10 区域）徘徊。显然，让玩家进入该区域后，让僵尸追击玩家，太难了。

import pygame,random,os
from pygame.locals import *

pygame.init()

scr_width = 1020
scr_height = 510
screen = pygame.display.set_mode((scr_width,scr_height))

clock = pygame.time.Clock()

images = {}
path = 'Desktop/Files/Dungeon Minigame/'
filenames = [f for f in os.listdir(path) if f.endswith('.png')]
for name in filenames:
    imagename = os.path.splitext(name)[0]
    images[imagename] = pygame.image.load(os.path.join(path,name))

pygame.display.set_caption('Dungeon Minigame')

font = pygame.font.SysFont('Times_New_Roman',27)

white = [240,240,240]

fps = 60
lives = 3
score = 0

playerX = 510
playerY = 220
playerxchange = 0
playerychange = 0

def player(x,y):
    screen.blit(images['r_knight'],(playerX,playerY))

class Enemy:
    def __init__(self):
        self.x = random.randint(8,800)
        self.y = random.randint(8,440)
        self.moveX = 0
        self.moveY = 0

    def move(self):
        self.speed = 3
    def draw(self):
        screen.blit(images['r_zombie'],(self.x,self.y))

def enemy(x,y):
    screen.blit(images['r_zombie'],(x,y))

enemy_list = []
for i in range(4):
    new_enemy = Enemy()
    enemy_list.append(new_enemy)

while True:

    for enemy in enemy_list:
        enemy.move()
        enemy.draw()

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

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

解决方法

这是一些让敌人跟随玩家的代码

class Enemy:
def __init__(self,x,y,images,name):
    self.x = x
    self.y = y
    self.images = images
    self.animation_count = 0
    self.offset_x = random.randrange(-600,600)
    self.offset_y = random.randrange(-600,600)
    self.reset_offset = 0
    self.bullet_cooldown = 0
    self.health = 50

def main(self,display,player_pos_x,player_pos_y):


        if self.reset_offset == 0:
            self.offset_x = random.randrange(-400,400)
            self.offset_y = random.randrange(-400,400)
            self.reset_offset = random.randrange(75,100)
        else:
            self.reset_offset -= 1

        if player_pos_x + self.offset_x > self.x]:
            self.x += random.randrange(1,3)   
        elif player_pos_x + self.offset_x < self.x:
            self.x -= random.randrange(1,3)   
        if player_pos_y + self.offset_y > self.y:
            self.y += random.randrange(1,3)  
        elif player_pos_y + self.offset_y < self.y:
            self.y -= random.randrange(1,3)   

        display.blit(image,(self.x,self.y))
