public OnPlayerCommandText(playerid, cmdtext[])
{
    if (!strcmp(cmdtext, "/npcchangenode ", true, 15))
    {
        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[15]);

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

        new idx = 15;
        while (cmdtext[idx] != ' ' && cmdtext[idx] != '\0') idx++;
        while (cmdtext[idx] == ' ') idx++;

        if (cmdtext[idx] == '\0')
            return SendClientMessage(playerid, 0xFF0000FF, "Usage: /npcchangenode [nodeid] [linkid]");

        new linkid = strval(cmdtext[idx]);

        NPC_ChangeNode(npcid, nodeid, linkid);
        SendClientMessage(playerid, 0x00FF00FF, "NPC %d changed to node %d via link %d", npcid, nodeid, linkid);
        return 1;
    }
    return 0;
}

Notes​

  • The NPC must be currently playing a node before changing
  • The target node must be opened with NPC_OpenNode first
  • Link ID determines the transition path between nodes
  • Use this for creating complex navigation patterns
