python实现小游戏——飞机大战_register_shape('enemy1.gif') 出现黄色告警

这里主要使用turtle来开发，pygame来添加音效

参考：跟麦叔学Python - 1小时开发太空侵略者游戏

游戏介绍_哔哩哔哩_bilibili

安装

安装turtle

pip install turtle

安装pygame

pip install pygame

程序的末尾

在末尾处写上这两句

turtle.done()
game.mainloop()

创建游戏背景

设置700*700大小的背景

import turtle
 
game = turtle.Screen()
game.setup(700.700)
game.title('飞机大战')
game.bgpic('bg.png')
 
turtle.done()

创建玩家

注意：这里的图片都要用gif格式的

# 创建玩家
turtle.register_shape('player2.gif')
player = turtle.Turtle()
player.ht()
player.speed(0)
player.up()
player.shape('player2.gif')
player.setpos(0,-230)
player.st()

玩家左右移动

# 设置步长
player_step = 20
# 玩家左移和右移函数
def go_left():
    x = player.xcor()
    x = x - player_step
    if x < -300:
        x = -300
    player.setx(x)
 
def go_right():
    x = player.xcor()
    x = x + player_step
    if x > 300:
        x = 300
    player.setx(x)
 
turtle.listen()
# 左移和右移
turtle.onkey(go_left,'Left')
turtle.onkey(go_right,'Right')

创建敌人

这里创建6个敌人，每个敌人的初始位置随机

# 添加敌人
num = 6
inv_list = []
turtle.register_shape('enemy.gif')
for i in range(0,6):
    inv = turtle.Turtle()
    inv_list.append(inv)
    inv.ht()
    inv.speed(0)
    inv.up()
    inv.shape('enemy.gif')
    x = random.randint(-200,200)
    y = random.randint(100,220)
    inv.setpos(x,y)
    inv.st()

让敌人动起来

这个while循环是死循环，要写在后面

# 敌人动起来
inv_step = 5
go_back = False
while True:
    for inv in inv_list:
        x = inv.xcor()
        x += inv_step
        inv.setx(x)
        if inv.xcor() > 300 or inv.xcor() < -300:
            go_back = True
 
        # 掉头
        if go_back:
            inv_step *= -1
            go_back = False
            for inv in inv_list:
                y = inv.ycor()
                y -= 40
                inv.sety(y)

创建子弹

# 添加子弹
bomb = turtle.Turtle()
bomb.ht()
bomb.speed(0)
bomb.up()
bomb.shape('triangle')
bomb.color('yellow')
bomb.shapesize(0.5,0.5)
bomb.seth(90)
bomb.setpos(-350,-350)

按空格发射子弹

发射子弹

# 发射子弹
is_fired = False
def fire():
    global is_fired
    if is_fired == False:
        bomb.setpos(player.xcor(), player.ycor() + 30)
        bomb.st()
        is_fired = True
 
turtle.onkey(fire,'space')

子弹射出：

# 敌人动起来
inv_step = 5
go_back = False
bomb_step = 50
while True:
    for inv in inv_list:
        x = inv.xcor()
        x += inv_step
        inv.setx(x)
        if inv.xcor() > 300 or inv.xcor() < -300:
            go_back = True
 
        # 掉头
        if go_back:
            inv_step *= -1
            go_back = False
            for inv in inv_list:
                y = inv.ycor()
                y -= 40
                inv.sety(y)
 
    # 子弹被发射
    if is_fired:
        y = bomb.ycor()
        y += bomb_step
        bomb.sety(y)
        if y > 250:
            is_fired = False
            bomb.setpos(-350, -350)
            bomb.ht()

击杀敌人

打中后的敌人再次随机生成位置

# 敌人动起来
inv_step = 5
go_back = False
bomb_step = 50
while True:
    for inv in inv_list:
        x = inv.xcor()
        x += inv_step
        inv.setx(x)
        if inv.xcor() > 300 or inv.xcor() < -300:
            go_back = True
 
        # 打中敌人，并重新生成敌人位置
        if inv.distance(bomb) < 30:
            x = random.randint(-200, 200)
            y = random.randint(-50, 220)
            inv.setpos(x,y)
            is_fired = False
            bomb.setpos(-350,-350)
            bomb.ht()
 
        # 掉头
        if go_back:
            inv_step *= -1
            go_back = False
            for inv in inv_list:
                y = inv.ycor()
                y -= 40
                inv.sety(y)
    # 子弹被发射
    if is_fired:
        y = bomb.ycor()
        y += bomb_step
        bomb.sety(y)
        if y > 250:
            is_fired = False
            bomb.setpos(-350,-350)
            bomb.ht()

添加分数

# 添加分数
score = 0
pen = turtle.Turtle()
pen.color('white')
pen.speed(0)
pen.up()
pen.ht()
pen.setpos(-340,265)
score_string = "分数：%s" %score
pen.write(score_string,align="left",font=('Arial',12,'normal'))

# 敌人动起来
inv_step = 5

bomb_step = 50
while True:
    for inv in inv_list:
        x = inv.xcor()
        x += inv_step
        inv.setx(x)
        if inv.xcor() > 300 or inv.xcor() < -300:
            go_back = True
 
        # 打中敌人，并重新生成敌人位置
        if inv.distance(bomb) < 30:
            x = random.randint(-200, 200)
            y = random.randint(-50, 220)
            inv.setpos(x,y)
            is_fired = False
            bomb.setpos(-350,-350)
            bomb.ht()
 
            score += 10
            score_string = "分数：%s" % score
            pen.clear()
            pen.write(score_string, align="left", font=('Arial', 12, 'normal'))

            is_fired = False
            bomb.setpos(-350,-350)
            bomb.ht()

判定游戏结束

添加分界线

# 画一条线,敌人越过这条线游戏结束
t = turtle.Turtle()
t.pencolor("white")
 
t.penup()
t.goto(-350, -200)
t.pendown()
 
for i in range(35):

    t.forward(10)
    t.pendown()

敌人越过分界线，游戏结束

while True:
    # 游戏结束
    if game_over:

            bomb.setpos(-350,-350)

添加音效

# 音乐
pygame.init()
laser = pygame.mixer.Sound('laser.wav')
explosion = pygame.mixer.Sound('exp.wav')
bg = pygame.mixer.Sound('bg.wav')

# 使用bg音乐
