## **part_system_clear**
**清除粒子系统的设置还原为默认状态。**
#### **语法:**
part_system_clear(ind);
| 参数 | 描述 |
| :--- | :--- |
| ind | 要清除设置的粒子系统ID |
**返回:** N/A
#### **描述**
通过这个函数,您可以将索引系统清除到它的默认状态,删除所有发射器并重新设置深度和位置(如果更改的话)。使用此函数时要小心,因为如果使用与此系统关联的发射器,除非您使用part_emitter_exists函数优先检查判断,否则您可能会出现报错情况。在使用此函数后也不需要调用part_emitter_destroy函数来摧毁相关的发射器,因为它会被自动摧毁。
注意:这个函数会清除房间里可见的粒子,但它不清除粒子的属性,也不把它们从内存中移除。为此,应该使用part_type_clear和part_type_destroy函数。
#### **举例:**
```js
part_system_clear(global.Sname);
```
上面的代码将清除在全局变量“Sname”中索引的粒子系统到它的默认状态。
