利用Pygame制作躲避僵尸游戲

更新時(shí)間：2022年05月30日 08:14:39 作者：我的天才女友

本文參考了神廟逃亡，利用Pygame實(shí)現(xiàn)一個(gè)人躲避僵尸的小游戲，主要的是精靈、精靈組之間相撞、相交的處理，感興趣的可以了解一下

游戲玩法

根據(jù)神廟逃亡，實(shí)現(xiàn)一個(gè)人躲避僵尸的小游戲，主要的是精靈、精靈組之間相撞、相交的處理。

游戲開始隨機(jī)出現(xiàn)一定的僵尸，隨機(jī)移動(dòng)，玩家在一位置上，如果僵尸靠近玩家一定距離，則玩家持續(xù)掉血。玩家通過上下左右移動(dòng)躲避僵尸，屏幕會(huì)隨機(jī)刷新一個(gè)加血包，玩家吃了就會(huì)加一定的血，并在此刷新血包。

property()

這個(gè)函數(shù)在類中返回新的屬性

property(get,set,del,doc)

參數(shù)如上所示，get、set、del分別是獲取設(shè)值刪除調(diào)用的，doc是描述的。

精靈類

在原來的精靈類中添加方向和屬性即可。

class MySprite(pygame.sprite.Sprite):
    def __init__(self, target):
        pygame.sprite.Sprite.__init__(self)
        self.master_image = None
        self.frame = 0
        self.old_frame = -1
        self.frame_width = 1
        self.frame_height = 1
        self.first_frame = 0
        self.last_frame = 0
        self.columns = 1
        self.last_time = 0
        self.direction = 0
        self.classification = "玩家"

    def load(self, filename, width, height, columns, direction, classification="玩家"):
        # 精靈的屬性
        self.classification = classification
        # 方向
        self.direction = direction
        # 載入圖片
        # 780 * 300
        self.master_image = pygame.image.load(filename).convert_alpha() # 載入圖片
        self.frame_width = width 
        self.frame_height = height 
        self.rect = Rect(0, 0, width, height)
        self.columns = columns 
        rect = self.master_image.get_rect() 
        self.last_frame = (rect.width // width) * (rect.height // height) - 1 

    def update(self, current_time, rate=30): # current_time 更新頻率 為30
        if current_time > self.last_time + rate: # 如果當(dāng)前事件 大于 最后的時(shí)間 + 當(dāng)前的節(jié)奏
            self.frame += 1 # 當(dāng)前的幀數(shù)加一
            if self.frame > self.last_frame: # 當(dāng)前最后一幀 則從第一幀開始
                self.frame = self.first_frame  # 從0開始
            self.last_time = current_time # 將最后幀值為30

        # build current frame only if it changed
        if self.frame != self.old_frame: # 當(dāng)前幀數(shù)不等于老的一幀
            frame_x = (self.frame % self.columns) * self.frame_width
            frame_y = (self.frame // self.columns) * self.frame_height
            rect = (frame_x, frame_y, self.frame_width, self.frame_height) # 更新對(duì)應(yīng)的位置
            self.image = self.master_image.subsurface(rect) # 循環(huán)箱已有的方向
            self.old_frame = self.frame

    def __str__(self):
        return str(self.frame) + "," + str(self.first_frame) + \
               "," + str(self.last_frame) + "," + str(self.frame_width) + \
               "," + str(self.frame_height) + "," + str(self.columns)

初始畫面

和原來一樣，先建立簡單的畫面。

import mySprite1
import pygame, sys, random
from pygame.locals import *


def print_text(font, x, y, text, color=(255, 255, 255)):
    imgText = font.render(text, True, color)
    screen.blit(imgText, (x, y))


# 設(shè)置窗口
pygame.init()
screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("勇闖后半夜")
font = pygame.font.Font(None, 30)
timer = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()
    key = pygame.key.get_pressed()
    if key[K_ESCAPE]:
        sys.exit()

    screen.fill((50, 50, 100))

    pygame.display.update()

精靈移動(dòng)函數(shù)

如果是僵尸遇到墻壁自動(dòng)反方向走，根據(jù)方向改變對(duì)應(yīng)的位置。

def reversal_direction(mySprite):
    direction = mySprite.direction
    if direction == 0:
        direction = 4
    elif direction == 2:
        direction = 6
    elif direction == 4:
        direction = 0
    elif direction == 6:
        direction = 2
    mySprite.direction = direction


def increment(mySprite, offset=1):
    # 上下左右
    direction = mySprite.direction
    rect = mySprite.rect
    if direction == 0:
        rect.y -= offset
    elif direction == 2:
        rect.x += offset
    elif direction == 4:
        rect.y += offset
    elif direction == 6:
        rect.x -= offset
    # 超出邊界的處理
    # 超出邊界flg
    boundary = False
    if rect.x < 0:
        rect.x = 0
        boundary = True
    if rect.x + mySprite.frame_width > 800:
        rect.x = 800 - mySprite.frame_width
        boundary = True
    if rect.y < 0:
        rect.y = 0
        boundary = True
    if rect.y + mySprite.frame_height > 600:
        rect.y = 600 - mySprite.frame_height
        boundary = True
    # 如果超出邊界而且是僵尸的話 則反轉(zhuǎn)方向
    if boundary and mySprite.classification == "僵尸":
        reversal_direction(mySprite)

加載玩家

這個(gè)是素材的圖，如上所示，奇數(shù)行便是對(duì)應(yīng)的方向移動(dòng)。文件大小是768 * 768，可以分為96 * 96的8張。

加載玩家

# 玩家
play_group = pygame.sprite.Group()

play = mySprite1()
play.load("farmer walk.png", 96, 96, 8)
play.direction = -1
play_group.rect.x = 96
play_group.rect.y = 96
play_group.add(play)

	play_group.update(ticks, 50)
    screen.fill((50, 50, 100))

    play_group.draw(screen)
    pygame.display.update()

通過改變幀數(shù)修改，根據(jù)游戲的結(jié)束或是否移動(dòng)，改變對(duì)應(yīng)的事件

    if not game_over:
        play.first_frame = play.direction * play.columns
        play.last_frame = play.first_frame + play.columns - 1
        if play.frame < play.first_frame:
            play.frame = play.first_frame

    if not play_moving:
        play.frame = play.first_frame = play.last_frame
    else:
        increment(play)

控制交互

    if key[K_ESCAPE]:
        sys.exit()
    elif key[K_UP]:
        play.direction = 0
        play_moving = True
    elif key[K_DOWN]:
        play.direction = 4
        play_moving = True
    elif key[K_LEFT]:
        play.direction = 6
        play_moving = True
    elif key[K_RIGHT]:
        play.direction = 2
        play_moving = True
    else:
        play_moving = False

添加僵尸

# 隨機(jī)生成20個(gè)僵尸
for n in range(0, 10):
    zombie = MySprite()
    random_direction = random.randint(0, 3) * 2
    zombie.load("zombie walk.png", 96, 96, 8, random_direction, "僵尸")
    zombie.rect.x = random.randint(0, 600)
    zombie.rect.y = random.randint(0, 500)
    print(zombie.rect)
    zombie_group.add(zombie)
       
         # 設(shè)置僵尸
        for z in zombie_group:
            z.first_frame = z.direction * z.columns
            z.last_frame = z.first_frame + z.columns - 1
            if z.frame < z.first_frame:
                z.frame = z.first_frame
            increment(z)

添加血包

血包就是單純的一個(gè)圖的展示。

health = MySprite()
health.load("health.png", 32, 32, 1)
health.rect.x = random.randint(0, 600)
health.rect.y = random.randint(0, 500)
health_group.add(health)

精靈相互碰撞事件

主要是僵尸和人、人和血包之間的相撞事件

    # 相撞事件
    attack = None
    attack = pygame.sprite.spritecollideany(play, zombie_group)
    if attack is not None:
        if pygame.sprite.collide_rect_ratio(0.5)(play, attack):
            play_health -= 10
            attack.rect.x = random.randint(0, 600)
            attack.rect.y = random.randint(0, 500)
        else:
            attack = None

    if pygame.sprite.collide_rect_ratio(0.5)(play, health):
        play_health += 30
        if play_health > 100:
            play_health = 100
        health.rect.x = random.randint(0, 600)
        health.rect.y = random.randint(0, 500)

    if play_health <= 0:
        game_over = True
    
    # 顯示血量
    pygame.draw.rect(screen, (100, 200, 100, 180), Rect(300, 575, 200, 25))
    pygame.draw.rect(screen, (50, 150, 150, 180), Rect(300, 575, play_health * 2, 25))
