一、遊戲簡介

本遊戲是通過python編寫的小遊戲，給初學者熟悉python程式語言拋磚引玉，希望有所幫助。
成型的效果圖如下：

二、編寫步驟

1.引入庫

程式碼如下：

###### AUTHOR:破繭狂龍 ######
###### DATE:20201002 ######
###### DESCRIPTION:移動的木板 ######
import pygame
from pygame.locals import *
import sys
import time
import random

2.初始化

程式碼如下：

pygame.init()
BLACK = (0, 0, 0) # 黑色
WHITE = (255, 255, 255) # 白色
bg_color = (0,0,70)  # 背景顏色
red = (200, 0, 0)
green = (0, 200, 0)
bright_red = (255, 0, 0)
bright_green = (0, 255, 0)

smallText = pygame.font.SysFont('SimHei', 20) #comicsansms
midlText = pygame.font.SysFont('SimHei', 50)

barsize = [30, 10]
SCREEN_SIZE = [400, 500]  # 螢幕大小
BALL_SIZE = [15, 15]  # 球的尺寸
fontcolor = (255,255,255)  # 定義字型的顏色

myimg = r"img\b1.jpg"
background = pygame.image.load(myimg) # 圖片位置
background = pygame.transform.scale(background, SCREEN_SIZE)

# ball 初始位置
ball_pos_x = SCREEN_SIZE[0] // 2 - BALL_SIZE[0] / 2
ball_pos_y = 0

# ball 移動方向
ball_dir_y = 1  # 1:down
ball_pos = pygame.Rect(ball_pos_x, ball_pos_y, BALL_SIZE[0], BALL_SIZE[1])

clock = pygame.time.Clock()  # 定時器
screen = pygame.display.set_mode(SCREEN_SIZE)
# 設定標題
pygame.display.set_caption('python小遊戲-移動木板')
# 設定圖示
image = pygame.image.load(myimg)
pygame.display.set_icon(image)

3.相關自定義函式

程式碼如下：

###### 自定義函式 ######
def button(msg, x, y, w, h, ic, ac, action=None):
    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    if x + w > mouse[0] > x and y + h > mouse[1] > y:
        pygame.draw.rect(screen, ac, (x, y, w, h))
        if click[0] == 1 and action != None:
            action()
    else:
        pygame.draw.rect(screen, ic, (x, y, w, h))
    textSurf, textRect = text_objects(msg, smallText)
    textRect.center = ((x + (w / 2)), (y + (h / 2)))
    screen.blit(textSurf, textRect)

def text_objects(text, font):
    textSurface = font.render(text, True, fontcolor)
    return textSurface, textSurface.get_rect()

def quitgame():
    pygame.quit()
    quit()

def message_diaplay(text):
    largeText = pygame.font.SysFont('SimHei', 115)
    TextSurf, TextRect = text_objects(text, largeText)
    TextRect.center = ((screen[0] / 2), (screen[1] / 2))
    screen.blit(TextSurf, TextRect)
    pygame.display.update()
    time.sleep(2)
    game_loop()

---

4.相關自定義函式

程式碼如下：

def game_first_win():
    intro = True
    while intro:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()
        screen.fill(bg_color)
        ###遊戲名稱
        TextSurf, TextRect = text_objects('移動木板', midlText)
        TextRect.center = ((SCREEN_SIZE[0] / 2), (SCREEN_SIZE[1] / 2 - 70 ))
        screen.blit(TextSurf, TextRect)
        ###作者
        TextSurf_ZZ, TextRect_ZZ = text_objects('AUTHOR:破繭狂龍', smallText)
        TextRect_ZZ.center = ((SCREEN_SIZE[0] / 2), (SCREEN_SIZE[1] / 2 + 30))
        screen.blit(TextSurf_ZZ, TextRect_ZZ)
        button("開始", 60, 400, 100, 50, green, bright_green, game_loop)
        button("取消", 230, 400, 100, 50, red, bright_red, quitgame)
        pygame.display.update()
        clock.tick(15)

###### 移動的木板遊戲類 ######
def game_loop():
    pygame.mouse.set_visible(1)  # 移動滑鼠不可見
    ###變數###
    score = 0 #分數
    count_O = 0 #迴圈的次數變數1 用於統計等級
    count_N = 0 #迴圈的次數變數2 用於統計等級
    c_level = 1 #等級

    x_change = 0 #移動的變數
    x = SCREEN_SIZE[0] // 2 - barsize[0] // 2
    y = SCREEN_SIZE[1] - barsize[1]

    # ball 初始位置
    ball_pos_pz = ball_pos
    while True:
        bar_move_left = False
        bar_move_right = False
        ###當每次滿X分後，升級等級
        if count_O != count_N and score % 5 == 0:
            c_level += 1
        count_O = count_N
