You must have a ready NPC(to make go to the link below)

1st:
You must add this above OnGameModeInit

Code:

new Text3D:Botinfo;//you can change "Botinfo" to whatever you want

2nd:

Add this line under OnGameModeInit

Quote:

Botinfo = Create3DTextLabel("Bot_name_here",Colour_here,0.0, 0.0,0.0,30.0,0);

3rd

Add this line under OnPlayerSpawn

Code:

if(IsPlayerNPC(playerid)) //Checks if the player that just spawned is an NPC.
  {
    new npcname[MAX_PLAYER_NAME];
    GetPlayerName(playerid, npcname, sizeof(npcname)); //Getting the NPC's name.
    if(!strcmp(npcname, "NPC_connect_name", true)) 
    {
      Attach3DTextLabelToPlayer(Botinfo, playerid, 0.0, 0.0, 0.0);
      return 1;
    }

If your NPC is in a vehicle it will look like this :

Code:

if(IsPlayerNPC(playerid)) //Checks if the player that just spawned is an NPC.
  {
    new npcname[MAX_PLAYER_NAME];
    GetPlayerName(playerid, npcname, sizeof(npcname)); //Getting the NPC's name.
    if(!strcmp(npcname, "NPC_connect_name", true)) 
    {
      Attach3DTextLabelToPlayer(Botinfo, playerid, 0.0, 0.0, 0.0);
	  PutPlayerInVehicle(playerid, NRG500, 0); //you must have created a vehicle for it!
      return 1;
    }

And thats it! Hope it helped!
