# 用 python 做遊戲!

使用 pygame 模組製作，它專門用來製作遊戲。可以非常簡單的生成界面，以及載入圖像、聲音，並控制其輸出。


### 生成介面
特別提醒 : 如果沒有loop迴圈的話 介面會馬上關閉喔~

 pygame.display.set_mode((window_width, window_height)

### 載入圖片

 pygame.image.load('picture.png')

### 將圖片繪製出來

 pygame.display.set_mode((window_width, window_height)
    .blit(pygame.image.load('picture.png'),(x,y))

### 聲音

 pygame.mixer.music.load("music.mp3")
 # 撥放音樂
 pygame.mixer.music.play()
 # 暫停音樂
 pygame.mixer.music.pause()

### 偵測鍵盤

pygame.KEYDOWN

用以上功能加上一些邏輯就能做出遊戲來啦

### 實作 接冰激淋

#### 遊戲方法
讓小豬避開維尼把冰激淋都接起來!接到會加分，沒接到會扣分喔
#### 設計邏輯
#### 成果展示

#### 程式碼
