## Description

Checks if an NPC ID is valid and the NPC exists.

## Returns

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

        new bool:isValid = NPC_IsValid(npcid);

        SendClientMessage(playerid, 0x00FF00FF, "NPC %d is valid: %s", npcid, isValid ? "Yes" : "No");
        return 1;
    }
    return 0;

## Notes

tip

-   Always check if an NPC is valid before performing operations on it. This prevents runtime errors and crashes.
-   Use this in loops when iterating through potential NPC IDs.

note

An NPC becomes invalid when it is destroyed.
