I'm looking to make it to where if a projectile comes into contact with netherrack it will set a tiny 1 block fire if possible.

Ifnit is a custom projectile there is an onImpact method, otherwise use the ThrowableImpactEvent

EntityOrb is a rewritten form of EntityThrowable

EntityFireOrb Extends EntityOrb

Like Snowball extends EntityThrowable.

Both EntityOrb And EntityThrowable extends entity and implements Iprojectile

You are literally passing null into a method, so of course you are getting an NPE.

well I went this way with it too.

BlockPos blockpos = new BlockPos(this.xTile, this.yTile, this.zTile);

if (worldObj.getBlockState(blockpos) == Blocks.COAL_BLOCK.getDefaultState())

{

this.worldObj.setBlockState( blockpos, Blocks.FIRE.getDefaultState());

}

and i still come up with the same crash report.

It should be able to go like this:

if (result.blockHit = Blocks.COAL_BLOCK)

{

this.setBlock(posX, posY, posZ);

setBlock = FIRE

}

or something like that...

forge is too friggin complicated.

like alright... I'd like to set a block on fire with a projectile.

Lemme research that for the next 5 days and possibly fail or succeed at doing it.

(nope, time to play some league)

Chunk coords are completely different that what you are looking for you can grab the position from the MovingObjectPosition.

These two objects are not the same. You should come back when you understand Java because it is clear that you do not know wtf you are doing.

Bad pathfinding for big mobs (1.21.1)

hey
do u want someone to make this for you

By dark phonis · 5 hours ago5 hr
(((SOLVED))) Loading into certain worlds stuck on "Reading world data" then stops responding.

So, I tried this, and the world did load, but ALL of the modded items and things I had completely disappeared, as well as many unmodded things like my chests and items I was carrying. Any solutions?

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
