Hello, I'm trying to create an explosive arrow and I experienced one issue, using this 

onUpdate

(Yeah copied the EntityArrow code) and using my bow (which is simply extends ItemBow) the arrow one it lands keep dying and respawn causing a horrible sound without creating any explosion.

public class EntityExplosiveArrow extends EntityArrow {

You are already extending EntityArrow. Why did you copy its code again?

If you want to create an explosion after hitting something, and you have already extended EntityArrow, you should override the onHit() method and add some code to make it explode.

Work! Thanks. Now I have to know why when I use the arrow I see it fall after I shoot the arrow. I mean, it works but I shoot the arrow and it "fell" on the ground but it teleports me where it lands.

How is when I shoot the arrow:

Show your updated code.

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.

You might have set the player's position to the arrow's pos somewhere in onHit().

@Override
	protected void onHit(RayTraceResult raytraceResultIn) {
		BlockPos blockpos = raytraceResultIn.getBlockPos();
		if (this.shootingEntity instanceof EntityPlayer) {
			EntityPlayer player = (EntityPlayer) this.shootingEntity;
			System.out.println(blockpos);

			int y = blockpos.getY();
			int z = blockpos.getZ();
			world.createExplosion(player, x, y, z, 4, true);
			this.setDead();

The system.out.println prints where the arrow lands (and where it create the explosion)

Sorry, I didn't see your question so I asked.

 

I only added 

onHit

The class:

public class EntityTeleportArrow extends EntityArrow {

	public EntityTeleportArrow(World worldIn) {
		super(worldIn);
	}

	public EntityTeleportArrow(World worldIn, double x, double y, double z) {
		super(worldIn, x, y, z);
	}

	public EntityTeleportArrow(World worldIn, EntityLivingBase shooter) {
		super(worldIn, shooter);
	}

	@Override
	protected ItemStack getArrowStack() {
		return null;
	}

	@Override
	protected void onHit(RayTraceResult raytraceResultIn) {
		BlockPos blockpos = raytraceResultIn.getBlockPos();
		if (this.shootingEntity instanceof EntityPlayer) {

So what are you asking is why the arrow falls directly into the ground when it shoots.

I'm not sure but I think you will need to override and rewrite some methods in your bow class.

Try changing false to true when you register it. You should also be using the Registry event for entities.

Expand  

Umm no. The 64 in the registering is the tracking distance; it has nothing to do with the teleport distance.

You can edit your bow to shoot the arrow with more velocity.

Teleport or create the explosion... It was the same. I had the same problem.

Oh, okay then I didn't get teleported because low render distance (was 4)

The tracking distance determines whether the entity should be rendered at a certain distance. It does not affect aspects like teleportation and explosion.
