# NPC\_GetNodePointCount

注意

这个函数是在omp v1.5.8.3079中添加的，在以前的版本中不起作用！

## 描述

获取 NPC 节点中点的数量。

| 参数 | 说明 |
| --- | --- |
| nodeid | 节点的 ID |

## 返回值

返回节点中点的数量，若节点无效则返回 0。

## 示例

```c
public OnPlayerCommandText(playerid, cmdtext[])
{
    if (!strcmp(cmdtext, "/checknodepointcount ", true, 21))
    {
        new nodeid = strval(cmdtext[21]);

        if (nodeid < 0 || nodeid > 63)
            return SendClientMessage(playerid, 0xFF0000FF, "无效的节点 ID。必须在 0 到 63 之间。");

        new count = NPC_GetNodePointCount(nodeid);

        SendClientMessage(playerid, 0x00FF00FF, "节点 %d 有 %d 个点", nodeid, count);
        return 1;
    }
    return 0;
}
```

## 注意事项

-   若节点无效或未打开则返回 0
-   点的数量表示节点内的导航路径点
