[1.7.10] Server Crash With Custom Particles

Posted March 31, 201510 yr

So, I added EntityFX derived particles, and the dedicated server crashes on startup, because:

Attempted to load class net/minecraft/client/particle/EntityFX for invalid side SERVER

The issue is, I surrounded all creation of instances of the EntityFX derived classes with world.isRemote checks, and the error hasn't gone away, so I'm not sure what's wrong here.

You should not ever use client-only methods/class if it is neither in proxy nor with sideonly annotation,

even if you have something like if(worldObj.isRemote).

Although it would never be called, The code snippet will be loaded anyway.

I recommend you to move the EntityFX spawning code into the proxy class.

Yeah I was suspecting I needed to do that, but had to go to bed after posting that message

So, what should I be doing for the particles made inside onUpdate() in the entity an item fires? I need to give the particle constructor a world object, which I'm going to have to get by getting the player via their entity ID then getting the worldObj from that afaik, but I don't have access to the player to be able to get their ID in onUpdate, so what should I do about that?

Also, the particles made in clientProxy from the item right click don't show up in SMP, but they show up in SSP.

Nevermind, I was being a derp. But now this brings up a bigger issue, the release/firing of the beam from the light staff crashes the server in SMP, all particles crash SSP with

And everything besides the light staff firing (it has a charge period, which spawns particles, then release like a bow to fire) gives continual errors on SMP:

You're sending the packet to the server. Just do "sendTo" not "sendToAll".

Is the comment wrong then? It says sendToAll is client side, and if I cant use that, then should I use sendToAllAround to get the other players too? And how am I getting the player instance inside onUpdate in the entity classes?

Quote

April 1, 201510 yr

Because this is a client class, you can get the instance of Minecraft "Minecraft mc = Minecraft.getMinecraft" and use the "thePlayer". I believe when you do sendToAll, it thinks there is more than one player. Just try my idea and see if it works. If it doesn't, then your packet is returning null.

That gets rid of most of the crashes, but the particles still aren't showing up on SSP or SMP, the light beam entity crashes the server when spawned in SMP because I had no isRemote check around it which I go into later, it works fine in SSP, and none of the other entities are getting spawned at all. I then realized I had limited the entity spawning to the client side on everything except the light beam, which I forgot to put an isRemote around, which was the cause for the crash, and for the rest, of course was doing nothing because you dont spawn entities client side, but I can't change that to server side, or it'll crash because of the client sided stuff I'm now doing inside the entity class. What do?

Hm. You load the entity texture in your client proxy, correct?

The entity doesn't have a texture, I'm using its position to spawn particles, though giving the entity a texture sounds like it'd be useful to replace the core FXs, I didn't know you could do that.

I did a bit of experimenting, and discovered I have to use sendToAll when the packet sending is inside an entity, so now everything works on SSP, albeit the particles spawned within an item class are offset down at the player's feet, but in SMP, all 3 entities created by these staves crash the server on creation.

PS sendToAll works everywhere, so using that instead.

So, it didn't like this.setVelocity, which I didn't know was client sided until this prompted me to read the comments on that function, so changed it to this.motionX /= 10 etc and the entites spawn fine now. I changed it to check for client and then directly spawn particles in the entity classes, but the particles on the beam still aren't spawning on SMP, and don't spawn on SSP anymore.

			}
			mob.addPotionEffect(new PotionEffect(Potion.moveSlowdown.id, 300, 10));

	}

It was a leftover !world.isRemote check for spawning the entity. Strangely, the particles in onImpact still aren't spawning, do I need packets for those?

@Override
protected void onImpact(MovingObjectPosition mop)
{
	if(mop.entityHit != null)
	{
		if(mop.entityHit != this.getThrower() && this.getThrower() instanceof EntityPlayer && mop.entityHit instanceof EntityLiving)
		{
			EntityLiving mob = (EntityLiving)mop.entityHit;
			double x, y, z;
			Random rand = new Random();
			for(int i = 0; i < 20; i++)
			{
				x = mob.posX + (rand.nextInt(2) - 1 * rand.nextFloat());
				y = mob.posY;
				z = mob.posZ + (rand.nextInt(2) - 1 * rand.nextFloat());
				if(worldObj.isRemote)
				{
					ArcaneArtificing.proxy.doParticles(worldObj, Reference.LightBeamHitFX, x, y + 1, z, (x - mob.posX) * 0.01, 0, (z - mob.posZ) * 0.01, 10, 300);

			mob.addPotionEffect(new PotionEffect(Potion.moveSlowdown.id, 300, 10));
		}
		return;

Failed loading villager cartographer registered at cartographer - frozen tick

Allocated 10 Gb of ram. Could try again with more but I read using too much can slow things down as well. Going to try another big modpack and see if i can replicate the problem. It seems like this cartographer problem is kind of popular and doesn't have a solid solution yet, but i suspect its some generation mod since it's a crash that happens when specific chunks are being loaded. so i'll still try to lookout for what mod it could be as i add. i'll report back after testing as you suggested for a bit

I have no idea - is enough RAM allocated?
Do other pre-configured modpacks work? Maybe use such a modpack as working base and add new mods one by one
