            while (cmdtext[idx] == ' ') idx++;

            // Parse leftright if exists

            {
                leftright = strval(cmdtext[idx]);
            }
        }

        NPC_SetKeys(npcid, updown, leftright, keys);
        SendClientMessage(playerid, 0x00FF00FF, "NPC %d keys: keys=%d, ud=%d, lr=%d", npcid, keys, updown, leftright);

        return 1;
    }
    return 0;
}

Notes​

  • Keys affect NPC behavior in vehicles and on foot
  • Use NPC_GetKeys to check current key states
  • Key states persist until changed or NPC state resets

No specific callbacks are triggered by this function.
