如何让船不会停止拍摄时?

问题描述 投票:-1回答:1

“q”是移动,所以当你按“Q”在你的鼠标的方向移动,当你按“Q”再次停止。当你点击你的鼠标船将拍摄子弹,但它会暂停一秒钟。有没有一种方法,使之不会暂停。也可以让你的三角形火箭的画面?或背景画面的空间。

编码:

from turtle import Screen, Turtle, Vec2D, Turtle
import turtle
import time

screen = turtle.Screen()
screen.title("Test")
screen.setup(width=1000, height=650)

ship = turtle.Turtle()
ship.shape("triangle")
ship.turtlesize(3)
ship.speed('fast')
ship.penup()

bullet = turtle.Turtle()
bullet.shape("circle")
bullet.speed('fast')
bullet.color("green")
bullet.penup()
bullet.hideturtle()
bullet.goto(-525, -350)
bullet.hideturtle()
bullet.turtlesize(0.5)

shot=0

coin=-1
def onmove(self, fun, add=None):
    if fun is None:
        self.cv.unbind('<Motion>')
    else:
        def eventfun(event):
            fun(Vec2D(self.cv.canvasx(event.x) / self.xscale, -self.cv.canvasy(event.y) / self.yscale))

        self.cv.bind('<Motion>', eventfun, add)

def goto_handler(position):
    global target
    onmove(screen, None)
    target = position
    onmove(screen, goto_handler)

def move():
    global shot
    if -350<bullet.ycor() and bullet.ycor()<350 and -525<bullet.xcor() and bullet.xcor()<525:
        bullet.forward(15)
    ship.setheading(ship.towards(target))
    if coin==1:
        ship.forward(5)
    if shot==1:
        bullet.hideturtle()
        bullet.goto(ship.xcor(), ship.ycor())
        bullet.setheading(ship.heading())
        bullet.forward(15)
        bullet.showturtle()
        shot=0

    if -275>ship.ycor() or ship.ycor()>275 or -450>ship.xcor() or ship.xcor()>450:
        ship.backward(5)
    screen.ontimer(move, 50)


def shoot(x, y):
    global shot
    if not(-350<bullet.ycor() and bullet.ycor()<350 and -525<bullet.xcor() and bullet.xcor()<525):
        shot=1
def forward():
    global coin
    coin=-coin

target = (0, 0)

onmove(screen, goto_handler)

move()

screen.onscreenclick(shoot)
screen.onkeypress(forward, "q")
screen.listen()
screen.mainloop()
python turtle-graphics

我试着下面一点优化你的代码,使子弹的反应更迅速发射时。我做空间方,而不是长方形,所以没有在某些方向上再烧制比别人面前较长的延迟。我还参数,所以你可以选择不同大小的空间,它应该调整。我消除了shot变量,并使用龟的可见性状态改为:

from turtle import Screen, Turtle, Vec2D

SPACE = 825

CURSOR_SIZE = 20
BULLET_SIZE = 10
BULLET_BOUNDS = SPACE/2 + BULLET_SIZE/2

SHIP_SIZE = 60
SHIP_BOUNDS = SPACE/2 - SHIP_SIZE/2

def onmove(self, fun, add=None):
    if fun is None:
        self.cv.unbind('<Motion>')
    else:
        def eventfun(event):
            fun(Vec2D(self.cv.canvasx(event.x) / self.xscale, -self.cv.canvasy(event.y) / self.yscale))

        self.cv.bind('<Motion>', eventfun, add)

def goto_handler(position):
    global target

    onmove(screen, None)
    target = position
    onmove(screen, goto_handler)

def move():
    x, y = bullet.position()

    if -BULLET_BOUNDS < x < BULLET_BOUNDS and -BULLET_BOUNDS < y < BULLET_BOUNDS:
        bullet.forward(15)
    else:
        bullet.hideturtle()

    ship.setheading(ship.towards(target))

    if coin:
        x, y = ship.position()

        if -SHIP_BOUNDS < x < SHIP_BOUNDS and -SHIP_BOUNDS < y < SHIP_BOUNDS:
            pass
        else:
            ship.setheading(ship.towards((0, 0)))

        ship.forward(5)

    screen.ontimer(move, 50)

def shoot(x, y):

    screen.onscreenclick(None)

    if not bullet.isvisible():
        bullet.goto(ship.position())
        bullet.setheading(ship.heading())
        bullet.showturtle()
        bullet.forward(30)

    screen.onscreenclick(shoot)

def forward():
    global coin

    coin = not coin

screen = Screen()
screen.setup(width=SPACE, height=SPACE)

ship = Turtle("triangle")
ship.turtlesize(SHIP_SIZE / CURSOR_SIZE)
ship.speed('fastest')
ship.penup()

bullet = Turtle("circle", visible=False)
bullet.turtlesize(BULLET_SIZE / CURSOR_SIZE)
bullet.speed('fastest')
bullet.color("green")
bullet.penup()

coin = False
target = (0, 0)

onmove(screen, goto_handler)

move()

screen.onscreenclick(shoot)
screen.onkeypress(forward, "q")
screen.listen()
screen.mainloop()

要设置的背景下,找到一个大小比你需要更大的GIF格式(但不是一个生气勃勃的)空间图像。编辑下来到大小,并使用screen.bgpic("space.gif")使它的背景。

要使用船形象是一个困难的问题。设置乌龟使用GIF图像是简单,但图像将不宜与甲鱼转。这需要更多的图像,更多的代码和更多的时间。我想与你的三角形光标移到基于图像的飞船坚持。

或者,您可以使用多个带颜色的多边形绘制龟飞船,并设置为你的光标 - 它应该正确使用光标转动。看到这个qazxsw POI。
