# Spaceship 飞船
|
||
|
|
|
||
|
|
说明：飞船用以承载[机器人](Dev)一起移动
|
||
|
|
|
||
|
|
## 属性
|
||
|
|
|
||
|
|
### `x -> int`
|
||
|
|
|
||
|
|
**只读**，飞船的`x`坐标
|
||
|
|
|
||
|
|
### `y -> int`
|
||
|
|
|
||
|
|
**只读**，飞船的`y`坐标
|
||
|
|
|
||
|
|
## 方法
|
||
|
|
|
||
|
|
### `step(n) -> void`
|
||
|
|
|
||
|
|
飞船前进或后退指定步数，**本操作算作`n`步**
|
||
|
|
|
||
|
|
- `n`: 正整数，前进的步数
|
||
|
|
|
||
|
|
### `turnLeft() -> void`
|
||
|
|
|
||
|
|
飞船原地左转，机器人朝向不变，**本操作算作`1`步**
|
||
|
|
|
||
|
|
### `turnRight() -> void`
|
||
|
|
|
||
|
|
飞船原地右转，机器人朝向不变，**本操作算作`1`步**
|
||
|
|
|
||
|
|
## 示例用法
|
||
|
|
|
||
|
|
```python
|
||
|
|
# 获取飞船当前的x坐标
|
||
|
|
x = Spaceship.x
|
||
|
|
# 获取飞船当前的y坐标
|
||
|
|
y = Spaceship.y
|
||
|
|
|
||
|
|
# 飞船原地右转
|
||
|
|
Spaceship.turnRight()
|
||
|
|
# 飞船前进2步
|
||
|
|
Spaceship.step(2)
|
||
|
|
# 飞船原地左转
|
||
|
|
Spaceship.turnLeft()
|
||
|
|
# 飞船前进3步
|
||
|
|
Spaceship.step(3)
|
||
|
|
```
