# Flappy Bird
---
## 遊戲介紹
- **遊戲名稱**: Flappy Bird
- **遊戲目標**: 控制小鳥飛行，避免撞擊水管
- **開發工具**: Python, Pygame 庫
---
## 程式碼結構概述
- **主要模組**
```markdown
- `random` 和 `sys`: 內建模組，用於生成隨機數和系統操作
- `pygame`: 遊戲開發主要模組
---
## 初始化設定
- **視窗設定**
```python
window_width = 600
window_height = 499
window = pygame.display.set_mode((window_width, window_height))
```
- **圖像載入**
```python
pipeimage = 'Flappy Bird Images/pipe.png'
background_image = 'Flappy Bird Images/background.jpg'
birdplayer_image = 'Flappy Bird Images/bird.png'
sealevel_image = 'Flappy Bird Images/base.jfif'
```
---
## 主遊戲循環
- **初始化變量**
```python
your_score = 0
horizontal = int(window_width/5)
vertical = int(window_width/2)
```
- **事件處理**
```python
for event in pygame.event.get():
if event.type == QUIT or (event.type == KEYDOWN and event.key == K_ESCAPE):
pygame.quit()
sys.exit()
if event.type == KEYDOWN and (event.key == K_SPACE or event.key == K_UP):
if vertical > 0:
bird_velocity_y = bird_flap_velocity
bird_flapped = True
```
---
## 遊戲功能實現
- **碰撞測試**
```python
def isGameOver(horizontal, vertical, up_pipes, down_pipes):
if vertical > elevation - 25 or vertical < 0:
return True
...
```
- **水管生成**
```python
def createPipe():
offset = window_height/3
pipeHeight = game_images['pipeimage'][0].get_height()
...
return pipe
```
---
## 遊戲邏輯
- **小鳥的運動**
```python
if bird_velocity_y < bird_Max_Vel_Y and not bird_flapped:
bird_velocity_y += birdAccY
if bird_flapped:
bird_flapped = False
playerHeight = game_images['flappybird'].get_height()
vertical = vertical + min(bird_velocity_y, elevation - vertical - playerHeight)
```
- **水管的運動**
```python
for upperPipe, lowerPipe in zip(up_pipes, down_pipes):
upperPipe['x'] += pipeVelX
lowerPipe['x'] += pipeVelX
```
---
## 分數計算
- **分數顯示**
```python
numbers = [int(x) for x in list(str(your_score))]
...
for num in numbers:
window.blit(game_images['scoreimages'][num], (Xoffset, window_width*0.02))
Xoffset += game_images['scoreimages'][num].get_width()
```
