Hi, I created a boss and want a way to spawn him. I have a block in my mod that allows players (and items) to walk through. So to spawn the boss, you throw 4 items into the block, the items and the block disappear and the boss spawns. For some reason this wont work. The lightning strikes but I get no sound or fire and I get the boss bar but I dont see him. To further test this, I made it place a diamond block when you throw the items. The block does appear but when you right click it, it goes back to the old block. Does anyone know why this is happening?

I think your sided stuff is slightly messed up.

 

First of all, you're spawning the entity on the client side, not on the server side.  The way you're getting the world is a client-side method and will crash when used on server.  If it does spawn on client, it will disappear almost immediately or at least cause other trouble.

 

So you need to grab the world from the entity parameter, and check !entity.worldObj.isRemote to ensure you are on server side before spawning.  And you need to use that worldObj as well for the spawn to avoid crash.

 

I'm actually not sure why it isn't already crashing for you (the Minecraft call should crash on server) so maybe that method is only being called on the client side.  If you are detecting the spawn condition on the client side you then need to pass the information to the server with a custom packet, and the server should spawn the boss based on receiving that packet.

 

You should also use @Override annotation as it is good practice to find any typographical or logical mistakes as it will warn you if the method declaration doesn't match the format of the method you think you're overriding.

Why not grab the world from the world parameter?

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

Ok this is the new code. Now it happens like you said it would. The boss spawns for a few seconds then disappears, although the diamond block and lightning work just fine.

 

 
public void onEntityCollidedWithBlock(World world1, int x,
		int y, int z, Entity entity) {


	if (!(entity instanceof EntityPlayer)) {
		entity.setDead();
	}

	System.out.println(entity);
	if (entity instanceof EntityItem) {
		if (entity.toString().contains("spideressence")) {
			spider = true;
		}

		if (entity.toString().contains("bonehelmet")) {
			skull = true;
		}
		if (entity.toString().contains("creeperessence")) {
			creeper = true;
		}

		if (entity.toString().contains("zombieeessence")) {
			zombie = true;
		}

		if(spider && skull && creeper && zombie){

			World world = entity.worldObj;

			if(!world.isRemote){

			shouldSpawn = true;

			EntitySoulBossMob boss = new EntitySoulBossMob(world);

			boss.posX = x + 2;
			boss.posY= y + 2;
			boss.posZ = z +2 ;

			world.spawnEntityInWorld(new EntityLightningBolt(world, x, y, z));
			world.setBlockToAir(x, y, z);
			world.setBlock(x, y, z, Blocks.diamond_block); // for testing purposes. 
			world.spawnEntityInWorld(boss);
			}

		}


	}

}

Not sure what the problem is.  You're now properly spawning on server, so any disappearance is for different reason.  I'm not sure it is even related to the spawn.

 

Is there other code in your boss that would either make it jump positions, render invisibly, or die unexpectedly?

 

I would put in a console statement in your boss entity that prints out the posX, posY, and posZ every tick.  Then you'll see if it has moved somewhere, and also will notice if it dies (since nothing will print).

I did the print line and the boss does spawn, then he just disappears (the coordinates print out about 5 times then he dies. Here is his code

Do the coordinates make sense?  Like are they where you expect them?

 

It is good to confirm the side that the instance is running on.  Furthermore, if the printouts stop after a few times, then the entity must be "dying" because the onUpdate() should fire.  You need to figure out why that is happening.  But to confirm that it is dying, maybe also print out the public isDead field.  So try this and post what the console says.

 

System.out.println("X: " + this.posX + ",Y:" + this.posY + ",Z:" + this.posZ+", client side? ="+worldObj.isRemote)+", isDead ="+this.isDead);

Ok, this is what I get from that

 

 

X: -393.0,Y:6.0,Z:-482.0, client side? =true, isDead =false
X: -393.0,Y:6.0,Z:-482.0, client side? =false, isDead =false
X: -393.0,Y:6.0,Z:-482.0, client side? =true, isDead =false
X: -393.0,Y:5.9231925,Z:-482.0, client side? =true, isDead =false
X: -393.0,Y:5.772594574068951,Z:-482.0, client side? =true, isDead =false
X: -393.0,Y:5.551128321694432,Z:-482.0, client side? =true, isDead =false
X: -393.0,Y:5.261600127278932,Z:-482.0, client side? =true, isDead =false
X: -393.0,Y:4.906705242455058,Z:-482.0, client side? =true, isDead =false

 

Those are the first couple lines. After the 3rd time it stays the same. I'm not sure why client side is true since im only spawning when world is not remote. Also why is it true at first, turns false then goes back to true.

Posted

It should alternate because both client and server run the onUpdate() method in the class.  But it is very weird that server stops  (then client does).

 

I still think it is dying, but maybe the isDead is being updated between updates or something.  Let's try to override the setDead() method directly to see if we can catch it actually happening.  In your class put the following:

    @Override
    public void setDead()
    {
        System.out.println("setDead() called");
        this.isDead = true;
    }

 

Capture the console output again and post it here.

It's the same code I have above. The only condition I have to kill it is if the difficulty is peaceful. The mob works fine if spawned through its spawn egg, but dissapears if I spawn it in any other way.

    • When I first heard about Bitcoin back in 2018, I was skeptical. The idea of a decentralized, digital currency seemed too good to be true. But I was intrigued as I learned more about the technology behind it and its potential. I started small, investing just a few hundred dollars, dipping my toes into the cryptocurrency waters. At first, it was exhilarating to watch the value of my investment grow exponentially. I felt like I was part of the future, an early adopter of this revolutionary new asset. But that euphoria was short-lived. One day, I logged into my digital wallet only to find it empty - my Bitcoin had vanished without a trace. It turned out that the online exchange I had trusted had been hacked, and my funds were stolen. I was devastated, both financially and emotionally. All the potential I had seen in Bitcoin was tainted by the harsh reality that with decentralization came a lack of regulation and oversight. My hard-earned money was gone, lost to the ether of the digital world. This experience taught me a painful lesson about the price of trust in the uncharted territory of cryptocurrency. While the technology holds incredible promise, the risks can be catastrophic if you don't approach it with extreme caution. My Bitcoin investment gamble had failed, and I was left to pick up the pieces, wiser but poorer for having placed my faith in the wrong hands. My sincere appreciation goes to MUYERN TRUST HACKER. You are my hero in recovering my lost funds. Send a direct m a i l ( muyerntrusted ( @ ) mail-me ( . )c o m ) or message on whats app : + 1 ( 4-4-0 ) ( 3 -3 -5 ) ( 0-2-0-5 )
    • You could try posting a log (if there is no log at all, it may be the launcher you are using, the FAQ may have info on how to enable the log) as described in the FAQ, however this will probably need to be reported to/remedied by the mod author.
    • So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
    • It is 1.12.2 - I have no idea if there is a 1.12 pack
