## **part_system_position**
**设置粒子系统的位置。**
#### **语法:**
part_system_position(ind, x, y);
|参数| 描述|
|:---|:---|
|ind| 需要设置位置的粒子系统ID.|
|x| 坐标点X.|
|y| 坐标点Y.|
**返回:** N/A
#### **描述**
有了这个函数,你就可以修改粒子系统的基本位置(相对于房间(0,0)坐标),也就是说,与这个系统相关的所有其他粒子函数现在都将相对于这个新位置绘制出来。默认情况下,这个位置总是(0,0),但是在某些特殊情况下,您可能希望更改这个参数。
注意:这个函数将会改变粒子系统内的所有东西,所以如果你有一个发射器在位置(100,100),然后将粒子系统位置设置为(0,100),发射器现在将会绘制(100,200)。同样,如果您先设置基准位置,然后创建发射器,即使您在(100,100)创建它,它任然将被绘制(100,200)。
#### **举例:**
```js
if mouse_check_button_pressed(mb_left)
{
part_system_position(global.Sname, mouse_x, mouse_y);
}
```
上面的代码将检测按下鼠标左键时,在全局变量“Sname”中索引的粒子系统移动到鼠标的x、y位置
