Entity Ticking error :X

Posted October 16, 20168 yr

Hello @ all ,

after using my skill for example:

public class IceBall extends EntityThrowable
{
  public IceBall(World par1World)
  {
    super(par1World);
  }
  
  public IceBall(World par1World, EntityPlayer par3EntityPlayer)
  {
    super(par1World, par3EntityPlayer);
  }
  
  public IceBall(World par1World, double par2, double par4, double par6)
  {
    super(par1World, par2, par4, par6);
  }
  
  public int ticks = 20;
  
  public void onEntityUpdate()
  {
    if (this.ticks <= 0)
    {
      this.ticks = 20;
      setDead();
    }
    else
    {
      this.ticks -= 1;
    }
  }

when an "Entity" gets into the blocks ... the game crashes and the error log says "Entity Ticking" ... any idea?

On which line does the error occur? Please paste the content of that line of code.

Providing a detailed error log would be nice too.

I still haven't published a mod because I can never get that in-dev version just right to warrant a public release. And yes, after two years of mod development I am still learning to speak Java.

Whats Line 39? Im sure there are imports so we cant really see.

Without knowing the content of the code on line 39, my best bet would be that one of these elements you are accessing are null: location or IceBlock1.

I still haven't published a mod because I can never get that in-dev version just right to warrant a public release. And yes, after two years of mod development I am still learning to speak Java.

imports are

import java.util.ArrayList;
import java.util.List;

import ArturFarid.BlockUpdate.init.BlocksUpdate;
import net.minecraft.block.Block;
import net.minecraft.block.state.IBlockState;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.init.Blocks;

import net.minecraft.potion.PotionEffect;
import net.minecraft.util.BlockPos;
import net.minecraft.util.DamageSource;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;

line 39 is:

		for (int x = location.getX() - radius; x <= location.getX() + radius; x++) {

location is null.

This is passing null:

changeToIce(par1MovingObjectPosition.getBlockPos(), 5);

par1MovingObjectPosition.getBlockPos()

is not guaranteed to not be null.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

I understand what you're asking for, but I don't know how to do that. The settings have moved around a bit in the admin panel and I can no longer see a way of customising the editor. If you know how to customise the editor in Invision Community 5, let me know and I'll try applying it.

Yeah I saw, he just mentioned Fabric so I was wondering when it would be out.
@FoxyWoxy
When you are near (1-12ish blocks) the stab shot when it hits, the player gets launched around 50-100 blocks in the air

Thanks for your feedback and suggestions. The new forums run Invision Community 5 - some things are more customisable, other things a lot less. I'm happy to adjust the settings as desired but not sure where they'd be or if they're still available in the new version, so if you could let me know I'll give it a go.
