Python 乒乓球游戏代码：简单易懂的实现

下面是一个用Python编写的乒乓球游戏的示例代码：\n\npython\nimport turtle\n\nwin = turtle.Screen()\nwin.title("乒乓球游戏")\nwin.bgcolor("black")\nwin.setup(width=800, height=600)\nwin.tracer(0)\n\n# 乒乓球\nball = turtle.Turtle()\nball.speed(0)\nball.shape("square")\nball.color("white")\nball.penup()\nball.goto(0, 0)\nball.dx = 0.2\nball.dy = -0.2\n\n# 球拍 A\npaddle_a = turtle.Turtle()\npaddle_a.speed(0)\npaddle_a.shape("square")\npaddle_a.color("white")\npaddle_a.shapesize(stretch_wid=1, stretch_len=5)\npaddle_a.penup()\npaddle_a.goto(0, -250)\n\n# 球拍 B\npaddle_b = turtle.Turtle()\npaddle_b.speed(0)\npaddle_b.shape("square")\npaddle_b.color("white")\npaddle_b.shapesize(stretch_wid=1, stretch_len=5)\npaddle_b.penup()\npaddle_b.goto(0, 250)\n\n# 移动球拍 A\ndef paddle_a_left():\n x = paddle_a.xcor()\n if x > -380:\n x -= 20\n paddle_a.setx(x)\n\ndef paddle_a_right():\n x = paddle_a.xcor()\n if x < 380:\n x += 20\n paddle_a.setx(x)\n\n# 移动球拍 B\ndef paddle_b_left():\n x = paddle_b.xcor()\n if x > -380:\n x -= 20\n paddle_b.setx(x)\n\ndef paddle_b_right():\n x = paddle_b.xcor()\n if x < 380:\n x += 20\n paddle_b.setx(x)\n\n# 键盘监听\nwin.listen()\nwin.onkeypress(paddle_a_left, "a")\nwin.onkeypress(paddle_a_right, "d")\nwin.onkeypress(paddle_b_left, "Left")\nwin.onkeypress(paddle_b_right, "Right")\n\n# 游戏循环\nwhile True:\n win.update()\n\n # 移动乒乓球\n ball.setx(ball.xcor() + ball.dx)\n ball.sety(ball.ycor() + ball.dy)\n\n # 碰撞检测\n if ball.ycor() > 290:\n ball.sety(290)\n ball.dy *= -1\n\n if ball.ycor() < -290:\n ball.sety(-290)\n ball.dy *= -1\n\n if ball.xcor() > 390:\n ball.goto(0, 0)\n ball.dx *= -1\n\n if ball.xcor() < -390:\n ball.goto(0, 0)\n ball.dx *= -1\n\n if (ball.ycor() > 240 and ball.ycor() < 250) and (ball.xcor() > paddle_b.xcor() - 50 and ball.xcor() < paddle_b.xcor() + 50):\n ball.sety(240)\n ball.dy *= -1\n\n if (ball.ycor() < -240 and ball.ycor() > -250) and (ball.xcor() > paddle_a.xcor() - 50 and ball.xcor() < paddle_a.xcor() + 50):\n ball.sety(-240)\n ball.dy *= -1\n\n\n该代码使用了Python的turtle模块来创建游戏窗口和游戏元素。游戏窗口大小为800x600，乒乓球和球拍的移动通过控制球拍的x坐标来实现。玩家可以使用键盘上的a和d键来控制球拍A的移动，使用左右方向键来控制球拍B的移动。乒乓球会在碰到边界或球拍时反弹。\n\n你可以复制上述代码并运行它来体验乒乓球游戏。
