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

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

this is crashing the game when i throw the entity:

"

private int xTile;

private int yTile;

private int zTile;

"

 

"

public void onUpdate()

    {

    super.onUpdate();

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

"

 

"

    protected void onImpact(RayTraceResult result)

if (!this.worldObj.isRemote)

        {

            this.setDead();

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

{

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

}

well I went this way with it too.

 

private int xTile;

private int yTile;

private int zTile;

private BlockPos blockpos;

 

 

 

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.

hmmm....

 

still crashes.

 

This craps too complicated. I'm going to play some league.

 

public EntityFireOrb(World worldIn, EntityLivingBase throwerIn)
    {
        super(worldIn, throwerIn);
        this.fuse = 140;
        this.xTile = chunkCoordX;
        this.yTile = chunkCoordY;
        this.zTile = chunkCoordZ;
    }

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.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

private BlockPos blockpos;

...

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

 

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.

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.

But magic doesn't shot from a dispenser.

 

private BlockPos blockpos; //class field
...
BlockPos blockpos = new BlockPos(this.xTile, this.yTile, this.zTile); //local variable

 

Google "local scope"
