No callbacks?

[ghost]

Without callbacks this is very limited in it's use.

Just noticed there was one in .walk but It would be nice if there was one on .navigate so I didnt have to create my own function.

There are events. You're authorised to read the example

Is there a way I could add an option where it'd be like flee(position to run from) or something like that?

[rom1504]

I don't think it really belong in that package. You can code it in your bot. Just pick a random position from that position using bot.blockAt and try go there

[ghost]

thats not very reliable though, also I think it belongs in this package because what if you need to flee from a creep/skeleton/angry mob?

[rom1504]

this package is about going from A to B. It does that well.

Fleeing from an entity is by definition not reliable, in some cases it might even be impossible.

You could make another mineflayer plugins for this, it could use mineflayer-navigate for movement.

The way I suggested is a simple way to implement it but of course you're free to do something better.

Could you help me come up with an idea? I want to take the player's position and the mobs position and go backwards away from it what do you think I could do?

[rom1504]

something like that :

function norm(v) {
  return Math.sqrt(v.x*v.x + v.y*v.y + v.z*v.z)
}
function fleePosition(botPosition, entityPosition, distanceToFlee = 20) {
  const fromBotToEntity = entityPosition.minus(botPosition)
  const directionVector = fromBotToEntity.scaled(-distanceToFlee/norm(fromBotToEntity))
  return botPosition.plus(directionVector)
}

const fleePosition = fleePosition(bot.entity.position, yourEntity.position)
bot.navigate.to(fleePosition)
bot.navigate.on('pathFound', function (path) {
  bot.chat("found path. I can get there in " + path.length + " moves.");
});
bot.navigate.on('cannotFind', function (closestPath) {
  bot.chat("unable to find path. getting as close as possible");
  bot.navigate.walk(closestPath);
});
bot.navigate.on('arrived', function () {
  bot.chat("I have arrived");
});
bot.navigate.on('interrupted', function() {
  bot.chat("stopping");
});

You should add that as an example if it works!

[rom1504]

It should work but you need to replace the "yourEntity" by the entity you want to flee from (you can use bot.entities to get it) I didn't test it at all though, you can test it ;)

[ghost]

It worked! 😄 However its important to note that the timeout needs to be pretty low.

[ghost]

Also It'd be nice if the bot would be able to move on a chunk by chunk basis so if a coordinate is out of the bot's range of view it will slowly make its way there using its available chunks

I found a callback in the navigateTo function: bot.navigate.to(position, {onArrived () { // Your callback }})
