## **asset_get_index**
#### **语法:**
asset_get_index(name);
| 参数 | 描述 |
| --- | --- |
| name | 获取索引的游戏资产的名称。(字符串) |
**返回:**
实数
#### **描述**
您可以使用此功能从名称获取游戏资产的唯一标识索引。 如果到该资产,将返回被检查资产的唯一索引ID,否则该函数将返回值-1。 这个id可以在其他函数中使用,就像常规的索引值一样,比如sprite_index或者path_index。 请注意,尽管这个函数可以用来从字符串引用资源(参见下面的例子),但在使用资源之前,应该始终确保资产确实存在,否则可能会导致游戏崩溃。
注意:HTML5目标平台无法解析脚本的解析,因为会出现代码混淆而出现问题,使用该功能时应该考虑到这些问题。
#### **举例:**
~~~
var obj = asset_get_index("obj_Enemy_" + string(global.Level));
if obj > -1
{
instance_create_layer(random(room_width), random(room_height), obj, "Enemy_Layer");
}
~~~
上面的代码将从一个字符串中获得一个对象索引,如果该索引存在,则在游戏中创建对象的一个实例。
