Bot click on NPC?

[peter81745]

So i have written a bot that connects to a server, on the server there are npc's, to get to the Server. I Already managed to get the bot to the right npc but the problem is how can i make the bot do a rightclick on the npc?

[wvffle]

You can try bot.activateEntity(npcEntity)

[peter81745]

yeah but how do i get the npcEntity? I searched for a nearestEntity function and found this:

function nearestEntity(type) {
  var id, entity, dist;
  var best = null;
  var bestDistance = null;
  for(id in bot.entities) {
    entity = bot.entities[id];
    if(type && entity.type !== type) continue;
    if(entity === bot.entity) continue;
    dist = bot.entity.position.distanceTo(entity.position);
    if(!best || dist < bestDistance) {
      best = entity;
      bestDistance = dist;
    }
  }
  return best;
}

bot.on('login', function() {
  sleep(10000).then(() => {
    var entity=nearestEntity(bot.entities)
    bot.activateEntity(entity)
  })

but it doesnt work. i get the error.

[peter81745]

ok i solved the error but the bot still doesn't click on the npc

can somebody help me now?

What's the error ?

[plexigras]

the trader example might be worth a look at

We need one version of the code with the corresponding error.

[rom1504]

ok so the issue is you're trying to use openVillager on an entity which is not a villager. why is that ?

[peter81745]

I am trying to click on an NPC that looks like a normal player, when you rightclick on it you get teleported to another server. I also tried bot.mount or bot.useOn but the bot doesn't get send to the Server... and nothing happens

[wvffle]

Have you tried to activateEntity in front of the NPC?

[peter81745]

yes also didn't work...

[cyborgcodede]

Hi, did you find a way to click the NPC?

[wvffle]

@CyborgCodeDEV and @peter12908, you can use mcpd to check what packets does the client send to the NPC, then just give us the screenshot ;)

[cyborgcodede]

@wvffle ok I started mcpd and entered the IP in the settings but there are no packages listed. I also tried it with a localhost server but it didn't work either.

[wvffle]

You have to connect to the proxy server, which by default runs on the localhost:25566 and then record the packets

[cyborgcodede]

I connected through the proxy but now I get 'undefined' in MC. When I connect to my localhost I get this error in the console:

[11:20:47] [User Authenticator #1/ERROR]: Username 'zvq' tried to join with an invalid session
[11:20:47] [Server thread/INFO]: /127.0.0.1:54540 lost connection: Failed to verify username!

[cyborgcodede]

I set my localhost server to online-mode=false and now it works. When I click a npc on my localhost (Citizens NPC) it sends the use_entity packet twice:

first one looks like this:

Packet:

{
  "target": 3597,
  "mouse": 2,
  "x": -0.2303556501865387,
  "y": 1.304377555847168,
  "z": -0.4000000059604645
}

Meta:

{
  "size": 16,
  "name": "use_entity",
  "state": "play"
}

and second one looks like this:

Packet:

{
  "target": 3597,
  "mouse": 0,
  "x": null,
  "y": null,
  "z": null
}

Meta:

{
  "size": 4,
  "name": "use_entity",
  "state": "play"
}

But when I add a command to the NPC it gets executed perfectly fine on bot.useOn(entity) When I use exactly the same code on the server I want it to click the NPC, nothing happens

This is the entity data of the NPC I want to click:

Entity {

  _eventsCount: 0,
  _maxListeners: undefined,

Have IT works if yes can you Sand me the Code because I search for a log time and I didnt find a answer

Kannst du wenn es geklappt hat mit bitte den Code schicken ich verzweifele dran und bekomme es nicht hin auf Bausucht.net auf den npc zu drücken
