# 贪吃蛇游戏
|
|
|
|
这是一个用 Oraset B-5 编写的控制台贪吃蛇游戏！
|
|
|
|
## 游戏说明
|
|
|
|
使用方向键控制蛇的移动方向，吃食物得分。
|
|
|
|
## 运行方法
|
|
|
|
```bash
|
|
oraset examples/snake.ora
|
|
```
|
|
|
|
## 代码
|
|
|
|
```oraset
|
|
// snake.ora - 贪吃蛇游戏
|
|
// 使用 w/a/s/d 或方向键控制
|
|
// Oraset B-5 版本 - 使用数组存储蛇的位置

|
|
```
|
|
|
|
## 注意事项
|
|
|
|
这个版本使用了 Oraset B-5 的数组功能，代码更加简洁高效。
|
|
蛇的身体现在存储在数组中，可以无限增长。 |
