## **effect\_create\_below**
**在所有实例下创建一个简单的粒子特效**
#### **语法:**
effect\_create\_below\(kind, x, y, size, colour\);
| 参数 | 描述 |
| :--- | :--- |
| kind | 特效种类 \(使用一个系统自带的效果种类 见ef\_all\). |
| x | 对应特效的X坐标 |
| y | 对应特效的Y坐标 |
| size | 特效的大小 |
| colour | 特效的颜色 |
**返回:** N/A
#### **描述**
使用此功能,您可以在房间的所有实例下创建一个简单的效果(实际上创建的深度为100000)。 如果效果是除了ef\_rain和ef\_snow之外的话,那么您可以定义一个x / y位置来创建效果,大小则可以是0,1或2的值,其中0较小,1普通,2较大。
值得注意的是,这些特效的绘制可以在设置其绘制条件的,使用函数part_system_automatic_draw和part_system_automatic_update为粒子系统提供适当的值即可控制其绘制(索引0代表控制effect_create_below函数,索引1代表effect_create_above函数)。
#### **举例:**
```js
if speed > 0
{
effect_create_below(ef_smoke, x, y, 0, c_gray);
}
```
上面的代码代表当前实例速度大于0的每一步中在x,y坐标处创建创建一小撮烟。
