使基于 python 龟的游戏在点击时重置

如何解决使基于 python 龟的游戏在点击时重置

我正在尝试让我的游戏在用户点击屏幕后重新启动。我已经尝试将整个过程包装在一个 while 循环中，但这给了我关于未定义变量的错误。

我也试过将代码包装在一个函数中，但这也会给我带来变量错误。

这是代码。

    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'

我使用 pygame 只是为了将音乐添加到我的游戏中。

import turtle
import math
import random
import pygame

pygame.init()
pygame.mixer.init()

# MUSIC AND SOUND SETUP
pygame.mixer.music.load("Sounds/music.mp3")
pygame.mixer.music.play(loops=-1)

这是主循环，大部分代码都放在这里了。

bubblefiredsound = pygame.mixer.sound("Sounds/bubblefired.mp3")
enemyhitsound = pygame.mixer.sound("Sounds/enemyhit.mp3")

# SCREEN SETUP
screen = turtle.Screen()
screen.bgcolor("black")
screen.title("Space Invaders")
screen.bgpic("TurtleInvadersBackground.png")

turtle.register_shape("Enemy.gif")
turtle.register_shape("Turtle.gif")
turtle.register_shape("Bubble.gif")

# BORDERS
border_pen = turtle.Turtle()
border_pen.speed(0)
border_pen.color("white")
border_pen.penup()
border_pen.setposition(-300,-300)
border_pen.pendown()
border_pen.pensize(3)
for side in range(4):
    border_pen.fd(600)
    border_pen.lt(90)
border_pen.hideturtle()

# score
score = 0

score_pen = turtle.Turtle()
score_pen.speed(0)
score_pen.color("white")
score_pen.penup()
score_pen.setposition(-290,270)
scorestring = "score: %s" % score
score_pen.write(scorestring,False,align="left",font=("Bubble3D",20,"normal"))
score_pen.hideturtle()

# MAIN TURTLE
MajorTom = turtle.Turtle()
MajorTom.color("blue")
MajorTom.shape("Turtle.gif")
MajorTom.penup()
MajorTom.speed(0)
MajorTom.setposition(0,-250)
MajorTom.setheading(90)

# PLACEHOLDER FOR ENEMIES
enemies = []

# ADD ENEMIES TO THE PLACEHOLDER
for i in range(number_of_enemies):
    # CREATE ENEMIES
    enemies.append(turtle.Turtle())

for enemy in enemies:
    enemy.color("red")
    enemy.shape("Enemy.gif")
    enemy.penup()
    enemy.speed(0)
    x = random.randint(-200,200)
    y = random.randint(100,250)
    enemy.setposition(x,y)

# BUBBLE STATE,READY = READY TO FIRE,FIRE = FIRING
bubblestate = "ready"


# MOVEMENT (LEFT AND RIGHT)

        # MOVE BUBBLE TO MAJOR TOM
        x = MajorTom.xcor()
        y = MajorTom.ycor() + 10
        bubble.setposition(x,y)
        bubble.showturtle()

# KEYBINDINGS

解决方法

您正在寻找 turtle.onscreenclick 函数。
当点击屏幕时，使用鼠标当前的 x 和 y 坐标调用此函数。

def reset(x_pos,y_pos):
    # reset the game

turtle.onscreenclick(reset)
