[1.8] Entity move

Posted July 8, 20169 yr

Hi there,

I'm a newbie here.

I wanna build an entity that when I right click him, the entity moves to the certain position.

How can I make it?

Thx!

I tried to build an AI class, but it doesn't work :'(

package com.practise.ai;

import com.practise.NPC.EscortRequestNPC;

import net.minecraft.entity.EntityCreature;
import net.minecraft.entity.ai.EntityAIBase;
import net.minecraft.entity.ai.EntityAIMoveToBlock;
import net.minecraft.util.BlockPos;
import net.minecraft.world.World;

public class EscortRequestNPCai extends EntityAIBase{

private final EscortRequestNPC entity;

public EscortRequestNPCai(EscortRequestNPC entity){
	this.entity = entity;

}

@Override
public boolean shouldExecute() {
	if(entity.ifTrigger == true)
		return true;
	else
		return false;
}

@Override
public void startExecuting() {
	BlockPos NPCpos = entity.getPosition();
	int posX = NPCpos.getX();
	int posY = NPCpos.getY();
	int posZ = NPCpos.getZ();
	posX += 200;
	posY += 200;
	entity.getNavigator().tryMoveToXYZ(posX, posY, posZ, 2);
}

}

import net.minecraft.world.World;

public class EscortRequestNPC extends EntityVillager{


public EscortRequestNPC(World worldIn) {
	super(worldIn);	
	this.tasks.addTask(0, new EscortRequestNPCai(this));
}
public boolean ifTrigger = false;


@Override
public boolean interact(EntityPlayer player) {
	ifTrigger = true;
	return true;

Ok, the problem is, I can enter the method startExcuting, but it doesn't work.

I've changed my code to this:

package com.practise.ai;

import com.practise.NPC.EscortRequestNPC;

import net.minecraft.entity.EntityCreature;
import net.minecraft.entity.ai.EntityAIBase;
import net.minecraft.entity.ai.EntityAIMoveToBlock;
import net.minecraft.util.BlockPos;
import net.minecraft.world.World;

public class EscortRequestNPCai extends EntityAIBase{

private final EscortRequestNPC entity;
BlockPos NPCpos;
int posX;
int posY;
int posZ;

public EscortRequestNPCai(EscortRequestNPC entity){
	this.entity = entity;	
	NPCpos = entity.getPosition();
	posX = NPCpos.getX();
	posY = NPCpos.getY();
	posZ = NPCpos.getZ();
	posX += 200;
	posY += 200;
}



@Override
public boolean shouldExecute() {
	if(entity.ifTrigger == true)
		return true;
	else
		return false;
}

@Override
public void startExecuting() {
	for(int i=0;i !=10;i++)
		System.out.println("enter startExecuting!!!");
	entity.getNavigator().tryMoveToXYZ(posX, posY, posZ, 0.5);
}


}

When I right click the entity, the console gave me this:

[13:03:53] [server thread/INFO]: Player98 joined the game

[13:03:57] [server thread/INFO] [sTDOUT]: [com.practise.ai.EscortRequestNPCai:startExecuting:42]: enter startExecuting!!!

[13:03:58] [server thread/INFO]: Saving and pausing game...

So, it seems the "tryMoveToXYZ" method did not work.

	posX += 5;
	posY += 5;
}



@Override
public boolean shouldExecute() {
	if(entity.ifTrigger == true)
		return true;
	else
		return false;
}

@Override
public void startExecuting() {
	System.out.println(entity.getNavigator().tryMoveToXYZ((double)posX, (double)posY, (double)posZ, 2));
}
}

And the console gave me "false" result.

So I guess there must be something wrong with parameters? :'(

BTW, In class EscortRequestNPC, is interact being called when it should be? Do you ever clear ifTrigger to false? Does anything ever test for being at the XYZ so you can stop executing?

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

I believe so, with other classes I made, I used it a bunch of times, they work perfectly.

Do you ever clear ifTrigger to false?

Oh, I forgot about it, I'll definitely add this when the entity moves to certain position. But the problem is: it doesn't even move now.

Does anything ever test for being at the XYZ so you can stop executing?

The same answer with last one, it doesn't move now.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated

Bad pathfinding for big mobs (1.21.1)

I've struggled with this for way too long now, so I have decided to ask for some assistance here because there is almost no information about this online.

I made a hostile mob and I built it like this:
public static final Supplier<EntityType<Bunyip>> BUNYIP = ENTITY_TYPES.register("bunyip" , () -> EntityType.Builder. of(Bunyip::new, MobCategory.MONSTER).sized(3f, 2.5f).eyeHeight(1.75f).build("bunyip"));

However, I have discovered that a BoundingBox of 3 is too big for the vanilla pathfinding to work well. In fact, anything bigger than a block will not work well. This is especially noticeable when having it chase a player in a negative X and/or negative Z direction. The mob starts spinning, walking backwards, walking diagonally, etc.

I am using the Goal system:
protected void registerGoals() { super.registerGoals(); this.goalSelector.addGoal(1, new MeleeAttackGoal(this, 1.25, true)); this.targetSelector.addGoal(2, new NearestAttackableTargetGoal<>(this, Player.class, true, true)); }

This does not seem to be a me issue as the ravager, one of the biggest vanilla mobs, also struggles with proper pathfinding. I am a bit familiar with how Minecraft's pathfinding works, but not enough to make a pathfinding system from scratch (or at least not in a reasonable amount of time). Is there any way to fix this with some tweaks or will I have to make a custom pathfinding system?

New Forum Design/Update: Issues and Suggestions

Unfortunately, it seems that Invision has decided that everything is locked down and no longer customizable.
Their attitude to anyone who wants to edit anything is 'Just accept it we know best and screw you for even insinuating that you want to customize your own site'
So there isn't much we can do about the layout of actual features.
Best bet for the editor is that psudo markdown works, so typing ` around words make code blocks.
Only options is to start writing bespoke modifications to the forum's php code itself, which I really don't want to do.
I would of stayed on v4 but the version of PHP that it supports is going EOL and Invision has stated they have no intentions of upgrading it.
They also removed the central community for finding plugins/community addons.
Overall it is my feeling that they are intentionally trying to kill off self-hosting communities by removing features and locking things down, in an effort to force everyone into using their paid hosting services.

My HOPE is that someone in the overall forum community will write an exporter for Invision to something like SMF. Which is what we were originally on before old team members decided enterprise software is better.
