1) please use insert code when you do that (it do it easyer to read)

2) what i can see is that it can't find a class, if you look at the start

Exception in server tick loopjava.lang.NoClassDefFoundError: net/minecraft/client/renderer/entity/Renderat

if your are using 1 class like my for tick handling for server and client you do remember to but the @SideOnly(Side.CLIENT)?

As a modder you should never use @SideOnly. It screws things up badly.

 

@Op: Post your crash report properly. Also do NOT post the Minecraft crash report but the ForgeModLoader log file.

You are probably trying to register your renderers on the server, too, which won't work. You need a proper proxy system (before you ask: go to the wiki, there are tutorials.)

you do now that @SideOnly only so the code it's over will be that you set it to only

ex with armor do the server not need the textures the @SideOnly tuch one code and leave the rest do client and server

    @Override
    @SideOnly(Side.CLIENT)
    public String getArmorTextureFile(ItemStack itemstack) {
        if (itemstack.itemID == ModArmor.StoneHelmet.itemID || itemstack.itemID == ModArmor.StoneChestPlate.itemID || itemstack.itemID == ModArmor.StoneBoots.itemID){
            return "/assets/itempack/textures/armor/stone_1.png";
        } else if (itemstack.itemID == ModArmor.StoneLegs.itemID){
            return "/assets/itempack/textures/armor/stone_2.png";
        } else
        return null;
    }

and sometimes you will need to else will minecraft crash and i have tryed that

And again a little bit of my code:

 

package Optical.Items; //Package directory

 

/*

* Basic importing

*/

 

 

 

import java.io.File;

 

import net.minecraft.block.Block;

import net.minecraft.block.BlockFurnace;

import net.minecraft.creativetab.CreativeTabs;

import net.minecraft.entity.EnumCreatureType;

import net.minecraft.item.EnumToolMaterial;

import cpw.mods.fml.common.event.FMLPreInitializationEvent;

import cpw.mods.fml.common.network.NetworkMod;

 

/*

* Basic needed forge stuff

*/

@Mod(modid="OpticalItems",name="Optical Items",version="1.0",acceptedMinecraftVersions="1.5.2")

@NetworkMod(clientSideRequired=true,serverSideRequired= false)

 

So what do i need to change? I dont understand what i need to do with the @SideOnly right now

Because everyone says something else. So if i under stand i have the code:

 

/*

* Basic needed forge stuff

*/

@Mod(modid="OpticalItems",name="Optical Items",version="1.0",acceptedMinecraftVersions="1.5.2")

@NetworkMod(clientSideRequired=true,serverSideRequired= false)

 

I have to add

@Override

and

@SideOnly(Side.CLIENT)

 

So like this?

 

/*

* Basic needed forge stuff

*/

@Mod(modid="OpticalItems",name="Optical Items",version="1.0",acceptedMinecraftVersions="1.5.2")

@NetworkMod(clientSideRequired=true,serverSideRequired= false)

@Override

@SideOnly(Side.CLIENT)

But i dont understand this code:

  @Override

    @SideOnly(Side.CLIENT)

    public String getArmorTextureFile(ItemStack itemstack) {

        if (itemstack.itemID == ModArmor.StoneHelmet.itemID || itemstack.itemID == ModArmor.StoneChestPlate.itemID || itemstack.itemID == ModArmor.StoneBoots.itemID){

            return "/assets/itempack/textures/armor/stone_1.png";

        } else if (itemstack.itemID == ModArmor.StoneLegs.itemID){

            return "/assets/itempack/textures/armor/stone_2.png";

        } else

        return null;

    }

 

What do i have to edit?

Because i have one mob in the mod so probably is that the problem.

My mod works only in single player.

So what do i have to edit in that code for my mob entity?

diesieben07 is correct @SideOnly should only be used if the original method has it, everything else needs to go through your proxy.

 

 

poonkje112 on your mod files that are not client only look at your imports, delete any that start "net.minecraft.client" anything that errors needs to go through your proxy.

 

This should help

Yes but i have 2 classes that need that import.... Like:

 

My Model for my Mob

package Optical.Items;

 

[glow=red,2,300]import net.minecraft.client.model.ModelBase;

import net.minecraft.client.model.ModelRenderer;[/glow]

import net.minecraft.entity.Entity;

 

public class ModelSalamander extends ModelBase

{

  //fields

    ModelRenderer Body;

    ModelRenderer FootLeftB;

    ModelRenderer FootLeftF;

    ModelRenderer FootRightF;

    ModelRenderer FootRightB;

    ModelRenderer Head;

    ModelRenderer Shape1;

 

  public ModelSalamander()

And the render for my mob

 

package Optical.Items;

 

[glow=red,2,300]import net.minecraft.client.model.ModelBase;

import net.minecraft.client.renderer.entity.RenderLiving;[/glow]

import net.minecraft.entity.EntityLiving;

 

public class RenderSalamander extends RenderLiving{

protected ModelSalamander model;

 

And i allready set up the proxy.

models and rendering is client only  ;)

those classes are fine with net.minecraft.client imports because a server will not load them.

 

the model is called from the renderer and the renderer is called by the renderhandler and thats only called on the client.

So there is nothing i have to change everything runs through my proxy.

So now i dont understand what the problem is. Do i have to add

@SidedProxy(clientSide = "Optical.Items.ClientProxy", serverSide = "Optical.Items.CommonProxy")

public static CommonProxy proxy;

In all classes?

Because the server problem is still not fixed.
