# NPC\_PlayNode

warning

This function was added in omp v1.5.8.3079 and will not work in earlier versions!

## Description

Makes an NPC navigate through predefined navigation nodes using the game's built-in navigation system.

| Name | Description |
| --- | --- |
| npcid | The ID of the NPC |
| nodeId | The ID of the node to navigate |
| moveType | Movement type (default: NPC\_MOVE\_TYPE\_JOG) |
| Float:speed | Movement speed (default: NPC\_MOVE\_SPEED\_AUTO) |
| Float:radius | Radius around nodes to consider as reached (default: 0.0) |
| bool:setangle | Whether to update NPC's facing angle during navigation (default: true) |

## Returns

Returns `true` if the NPC started playing the node, `false` otherwise.

## Examples

```c
public OnPlayerCommandText(playerid, cmdtext[])
{
    if (!strcmp(cmdtext, "/npcplaynode ", true, 13))
    {
        new npcid = PlayerNPC[playerid];
        if (npcid == INVALID_NPC_ID)
            return SendClientMessage(playerid, 0xFF0000FF, "You are not debugging a NPC.");

        if (!NPC_IsValid(npcid))
            return SendClientMessage(playerid, 0xFF0000FF, "Invalid NPC.");

        new nodeid = strval(cmdtext[13]);

        if (nodeid < 0 || nodeid > 63)
            return SendClientMessage(playerid, 0xFF0000FF, "Invalid node ID. Must be between 0 and 63.");

        new bool:success = NPC_PlayNode(npcid, nodeid, NPC_MOVE_TYPE_JOG, NPC_MOVE_SPEED_AUTO, 0.0, true);

        SendClientMessage(playerid, 0x00FF00FF, "NPC %d play node %d: %s", npcid, nodeid, success ? "Success" : "Failed");
        return 1;
    }
    return 0;
}
```

## Notes

-   Nodes are predefined navigation points from the game's node files (IDs 0-63)
-   The node must be opened with `NPC_OpenNode` before it can be used
-   The NPC will automatically navigate between points within the specified node
-   Use `setAngle` parameter to control whether the NPC rotates to face movement direction
-   The `radius` parameter determines how close the NPC needs to get to each point
-   Node navigation can be paused, resumed, or stopped using related functions
