Custom particle crash on server only

[bltpyro]

I am trying to get my mod working on a server, and seems to be crashing because of my particles. Single player works fine. I get these errors:

 

cpw.mods.fml.common.LoaderException: java.lang.NoClassDefFoundError: bltpyro/mod/truesurvival/particles/EntityMagicStealFX

and further on

Caused by: java.lang.NoClassDefFoundError: net/minecraft/client/particle/EntityFX

 

 

 

which from what I understand has to do with the server trying to use client code. This seems to make sense since net.minecraft.client.particle.EntityFX has @SideOnly(Side.CLIENT), but then I'm trying to register it using

EntityRegistry.registerModEntity(EntityMagicStealFX.class, "MagicStealParticleFX", 30, this, 50, 5, true);

in my main mod file. Is the registering causing a problem on the server because of the @SideOnly(Side.CLIENT)? Is there something I'm doing wrong in how I register the particle? I can't seem to get past this issue. Thanks

Wow I feel stupid now. Guess I shouldn't believe everything I read on the internet. Not sure why I saw that in so many tutorials for particles then. Thanks

feels weird to bump an old topic, but im having the error of "Attempted to load class net/minecraft/client/multiplayer/WorldClient for invalid side SERVER" and "java.lang.ClassNotFoundException: net.minecraft.client.multiplayer.WorldClient" when i put the effect on one of my entities! and no i didn't declare it like he did! this is my main particle class:

 

 

package moreores.particles;

public class MoreOresParticleEffects
{
private static Minecraft mc = Minecraft.getMinecraft();
private static World theWorld = mc.theWorld;

public static EntityFX spawnParticle(String particleName, double par2, double par4, double par6, double par8, double par10, double par12)
{
if (mc != null && mc.renderViewEntity != null && mc.effectRenderer != null)
{
int var14 = mc.gameSettings.particleSetting;

if (var14 == 1 && theWorld.rand.nextInt(3) == 0)
{
var14 = 2;
}

double var15 = mc.renderViewEntity.posX - par2;
double var17 = mc.renderViewEntity.posY - par4;
double var19 = mc.renderViewEntity.posZ - par6;
EntityFX var21 = null;
double var22 = 16.0D;

if (var15 * var15 + var17 * var17 + var19 * var19 > var22 * var22)
{
return null;
}
else if (var14 > 1)
{
return null;
}
else
{
if (particleName.equals("blueSlime"))
{
				var21 = new EntityBreakingFX(theWorld, par2, par4, par6, MoreOres.blueJelly);
			}


mc.effectRenderer.addEffect((EntityFX)var21);
return (EntityFX)var21;
}
}
return null;
}
}

 

 

 

and this is how i put it in my entity class:

 

 

                MoreOresParticleEffects.spawnParticle("blueSlime", this.posX + (double)f2, this.boundingBox.minY, this.posZ + (double)f3, 0.0D, 0.0D, 0.0D); //i dont think the params matter much for this case

 

 

 

any ideas what i could do to make it not crash the server?

not call particle spawning on server side

[sorash67]

So which part should i make client-side only? The part in entity class?

 

-sorash67 || Skorpio

[hydroflame]

you dont call particle spawning from server side.

[sorash67]

Great help by just repeating what you said. Gee thanks mate.

[hydroflame]

great listener by continuing to try to make stupid things by calling particle spawning serverside WHICH YOU SHOULD NEVER DO

 

literally what part of "dont call particle spawning server side" do you not understand? you dont do it. its not a question of @Sideonly its a question of not writing the code 

[sorash67]

Where the hell am i declaring on the server side mr knowitall? -.-

 

-sorash67 || Skorpio

[hydroflame]

declaring what ? particle ? NOWHERE !!

 

how is it so hard to freacking check which side your on and not call something if youre server side

[sorash67]

Calling, declaring, whatever the hell you wanna frikin call it. If you say dont call it for server, tell me wherr im friking "calling" it.

[hydroflame]

declaring and calling mean 2 completelly different thing in coding. its not a question what i WANT to call it its a question of using the right word

since theres only 2 side i would have tought that if its not server side it would be client side

 

you have 2 pot, the cookie is not in the first one, where is it???

 

btw dont answer im not trying anymore

[GotoLink]

Well this:

Minecraft.getMinecraft();

Means your on the client side. Always.

 

It is a field in your object or called in its constructor ? Your object is client side.

Thus do not build your object nor call one of its methods on server side.

How to check which side you are on is left as an exercise.
