大家好！今天来用 python中的arcade库做小游戏。arcade库相对于pygame库知名度相对低一些，但我认为这个库做游戏也很不错。

1.整体代码

import arcade
import time
print("欢迎游玩反弹小球！  v1.0.2")
print("下面是一些操作提示,请认真阅读。")
print("1.左侧是玩家,用上键和下键进行移动;右侧是AI。")
print("2.打到球随机获得1-3个金币,没有打到球则自动退出游戏。")
print("5秒后进入游戏。")

time.sleep(5)

class MyWindow(arcade.Window):
    def __init__(self):
        super().__init__(600,700,"反弹小球")

    def setup(self):
        self.ball=arcade.Sprite("res/smallball.png",scale=1,center_x=400,center_y=200)
        self.block_1=arcade.Sprite("res/block_1.png",scale=1,center_x=15,center_y=350)
        self.block_2=arcade.Sprite("res/block_2.png",scale=1,center_x=585,center_y=350)
        self.line=arcade.Sprite("res/line.png",scale=1,center_x=300,center_y=350)

        self.speed=2
        self.ball.change_x=self.speed
        self.ball.change_y=self.speed
        self.ball.change_angle=1
        self.music=arcade.load_sound("res/get.mp3")
        self.music2=arcade.load_sound("res/end.mp3")
        self.coin=0
    
    def on_draw(self):
        arcade.start_render()
        self.ball.draw()
        self.block_1.draw()
        self.block_2.draw()
        self.line.draw()
        arcade.draw_text("玩家",140,50,(150,150,150),font_size=40,anchor_x="center",anchor_y="center",font_name="res/黑体.ttf")
        arcade.draw_text("AI",465,50,(150,150,150),font_size=40,anchor_x="center",anchor_y="center",font_name="res/黑体.ttf")

    def on_update(self, delta_time: float):
        
        if arcade.check_for_collision(self.block_1,self.ball)==True:
            self.ball.change_x=self.speed
            arcade.play_sound(self.music)
            self.coin+=1

        if arcade.check_for_collision(self.block_2,self.ball)==True:
            self.ball.change_x=-self.speed
            self.speed+=0.2
        if self.ball.top>=700:
            self.ball.change_y=-self.speed

        if self.ball.right>=600:
            self.ball.change_x=-self.speed

        if self.ball.bottom<=0:
            self.ball.change_y=self.speed            

        if self.ball.left<=0:
            arcade.play_sound(self.music2)
            time.sleep(2)
            print("恭喜您获得了",self.coin,"枚金币！")
            self.close()

        if self.block_1.change_y>0 and self.block_1.top>=700:
            self.block_1.top=700
            self.block_1.change_y=0

        if self.block_1.change_y<0 and self.block_1.bottom<=0:
            self.block_1.bottom=0
            self.block_1.change_y=0

        if self.block_2.change_y<0 and self.block_2.top<=0:
            self.block_2.top=700
            self.block_2.change_y=0

        if self.block_2.change_y<0 and self.block_2.bottom<=0:
            self.block_2.bottom=0
            self.block_2.change_y=0

        self.block_2.center_y=self.ball.center_y

        self.ball.update()
        self.block_1.update()
        self.block_2.update()

    def on_key_press(self, symbol: int, modifiers: int):
        if symbol==arcade.key.UP:

            if self.speed==5:
                self.speed=5

        if symbol==arcade.key.DOWN:

            self.speed+=0.2
            if self.speed==5:
                self.speed=3

    def on_key_release(self, symbol: int, modifiers: int):
        if symbol==arcade.key.UP or symbol==arcade.key.DOWN:
            self.block_1.change_y=0

win.setup()
arcade.run()
