# OnNPCDeath

warning

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

## Description

This callback is called when an NPC dies.

| Name | Description |
| --- | --- |
| npcid | The ID of the NPC that died |
| killerid | The ID of the player/NPC that killed the NPC (or INVALID\_PLAYER\_ID if none) |
| WEAPON:reason | The reason for death (weapon ID or death cause) |

## Examples

```c
public OnNPCDeath(npcid, killerid, WEAPON:reason)
{
    printf("[NPC] NPC %d died (killer: %d, weapon: %d)", npcid, killerid, _:reason);

    // Notify players tracking this NPC
    for (new playerid = 0; playerid < MAX_PLAYERS; playerid++)
    {
        if (!IsPlayerConnected(playerid))
            continue;

        if (PlayerNPC[playerid] == npcid)
        {
            if (killerid == INVALID_PLAYER_ID)
            {
                SendClientMessage(playerid, 0xFF0000FF, "Your tracked NPC %d died (weapon: %d)", npcid, _:reason);
            }
            else
            {
                SendClientMessage(playerid, 0xFF0000FF, "Your tracked NPC %d was killed by player %d (weapon: %d)", npcid, killerid, _:reason);
            }
        }
    }
    return 1;
}
```

## Notes

-   The `killerid` parameter will be `INVALID_PLAYER_ID` if the NPC death was not player inflicted
-   The `reason` parameter contains the weapon ID that caused the death (255 for unknown/other causes)
