python - python - 惩罚游戏如何加速元素

问题描述

我创建了简单的点球游戏，一切正常，但我想改进一下。目标在双方本身移动，我想做的是在得分时加快速度。我知道当 dx 为负时，它必须为 += 1，如果 dx 为正，它必须相反，所以 += -1。我考虑了范围内 dx 的 for 循环（-270, 0, -270） 和第二个用于积极变量的循环。我是 python 和编程本身的初学者，所以我很感激任何建议。我想加快 SL、SP 和 P。这些对象创造了目标。

解决方案

使用这样的程序，您尝试实时移动的对象越少越好。你的目标是三个必须一致移动的部分。下面的主要修复是将目标定义为海龟形状，因此目标只是需要操纵的一块。下面的第二个修复是while True:用定时事件替换 ，它在事件驱动的世界中没有位置：

from turtle import Screen, Turtle

sd = 1.0

FONT = ("Courier", 24, "normal")

def right():
    ball.forward(20)

def left():
    ball.backward(20)

def shoot():
    ball.direction = "up"

def shoot2():
    ball.direction = "stop"

def shoot1():
    if ball.direction == "up":
        ball.sety(ball.ycor() + sd * 2)

wn = Screen()
wn.bgcolor("black")
wn.title("karne")
wn.setup(width=800, height=600)
wn.tracer(False)

wn.register_shape("goal", ((-90, 30), (90, 30), (90, -30), (70, -30), (70, 10), (-70, 10), (-70, -30), (-90, -30)))

# pilka

ball = Turtle("circle")
ball.color("green")
ball.speed('fastest')
ball.penup()
ball.sety(-275)
ball.direction = "stop"

# scoring

pen = Turtle(visible=False)
pen.speed('fastest')
pen.color("white")
pen.penup()

# poprzeczka

p = Turtle("goal")
p.color("white")
p.speed('fastest')
p.seth(90)
p.penup()
p.sety(270)
p.dx = sd

score = 0
miss = 0

# binds
wn.onkeypress(right, "d")
wn.onkeypress(left, "a")
wn.onkeypress(shoot, "space")
wn.listen()

def move():
    global score, miss

    # goal moving
    p.setx(p.xcor() + p.dx)

    # goal borders check

    if p.xcor() > 330:
        p.setx(330)
        p.dx *= -1
    elif p.xcor() < -330:
        p.setx(-330)
        p.dx *= -1

    # ball and goal check
    if 270 < ball.ycor() < 280 and ball.distance(p) < 50:
        score += 1
        pen.clear()
        pen.write("Score:{} Miss:{} ".format(score, miss), align="center", font=FONT)
        shoot2()
        ball.goto(0, -275)
    elif ball.ycor() > 295:
        miss += 1
        score = 0
        pen.clear()
        pen.write("Score:{} Miss:{} ".format(score, miss), align="center", font=FONT)
        shoot2()
        ball.goto(0, -275)

    shoot1()

    wn.update()
    wn.ontimer(move, 25)

move()

wn.tracer(True)
wn.mainloop()

加上许多其他小修复来简化代码。
