# IsPlayerObjectMaterialSlotUsed

注意

这个函数是在omp v1.1.0.2612中添加的，在以前的版本中不起作用！

## 描述

检测指定玩家物体的材质槽位使用状态

| 参数 | 说明 |
| --- | --- |
| playerid | 目标玩家 ID |
| objectid | 玩家物体 ID |
| materialIndex | 材质槽位索引值（有效范围 0-15） |

## 返回值

返回材质槽位使用类型：

`0` - 未使用

`1` - 材质贴图

`2` - 文本贴图

## 示例代码

```c
new playerobjectid = CreatePlayerObject(playerid, 19371, 978.71143, -925.25708, 42.63720, 0.0, 0.0, 2.0);
SetPlayerObjectMaterial(playerid, playerobjectid, 0, 19341, "egg_texts", "easter_egg01", 0xFFFFFFFF);

new type = IsPlayerObjectMaterialSlotUsed(playerid, playerobjectid, 0);
// type值为1
```

另一示例：

```c
new playerobjectid = CreatePlayerObject(playerid, 19174, 986.42767, -983.14850, 40.95220, 0.0, 0.0, 186.0);
SetPlayerObjectMaterialText(playerid, playerobjectid, "OPEN.MP", 0,
    OBJECT_MATERIAL_SIZE_256x128, "Arial", 38, true, 0xFF0000FF, 0x00000000,
    OBJECT_MATERIAL_TEXT_ALIGN_LEFT);

new type = IsPlayerObjectMaterialSlotUsed(playerid, playerobjectid, 0);
// type值为2
```
