[Solved]Mod Not Working On Server - LoaderException

Posted August 17, 201213 yr

I get this weird error which I can't seem to remove.

I looked into the class not found error and learnt that class arp is ModelBase. I also looked into line 60 of DayZ_Base which is

DayZ_ClientProxy.loadDayzSounds();

DayZ_ClientProxy

package net.minecraft.src;


import java.io.File;
import net.minecraft.client.Minecraft;
import net.minecraftforge.client.MinecraftForgeClient;
import cpw.mods.fml.client.registry.RenderingRegistry;

public class DayZ_ClientProxy extends DayZ_CommonProxy
{
    public static void registerRenderInformation()
    {
        RenderingRegistry.instance().registerEntityRenderingHandler(DayZ_EntityZombie.class, new RenderBiped(new ModelZombie(), 0.5F));
        RenderingRegistry.instance().registerEntityRenderingHandler(DayZ_EntityCrawler.class, new DayZ_RenderCrawler(new DayZ_ModelCrawler(), 0.5F));
        RenderingRegistry.instance().registerEntityRenderingHandler(DayZ_EntityBandit.class, new RenderBiped(new ModelBiped(), 0.5F));
        RenderingRegistry.instance().registerEntityRenderingHandler(DayZ_EntityBullet.class, new DayZ_RenderBullet());
    }


    public static void loadDayzSounds()
    {
        Minecraft mc = ModLoader.getMinecraftInstance();
        mc.installResource("newsound/DayZ/reload.ogg", new File(mc.mcDataDir, "resources/newsound/DayZ/reload.ogg"));
        mc.installResource("newsound/DayZ/ak74u.ogg", new File(mc.mcDataDir, "resources/newsound/DayZ/ak74u.ogg"));
        mc.installResource("newsound/DayZ/makarov.ogg", new File(mc.mcDataDir, "resources/newsound/DayZ/makarov.ogg"));
        mc.installResource("newsound/DayZ/remington.ogg", new File(mc.mcDataDir, "resources/newsound/DayZ/remington.ogg"));
    }
}

Any help would be appreciated.

Interesting, somewhere you have a reference to ModelBase, find it, and move it to client only code.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Whoops I meant arp refers to ModelBiped. The only part I refer to ModelBiped is in DayZ_ClientProxy which is initialised (or whatever) in the main mod file under the load section as

DayZ_ClientProxy.registerRenderInformation();

I'd need to see full code, to see exactly how you're hardcoding a reference.

}

This is really bugging me as the error makes no cents. I did a search of the common source folder and the only file with ModelBiped in it is DayZ_ClientProxy. I haven't touched anywhere else.

You have hard references to client proxy.

Thats bad, take a look at SideProxy

So to fix this I would put

@SidedProxy(clientSide = "net.minecraft.src.DayZ_ClientProxy", serverSide = "net.minecraft.src.DayZ_CommonProxy")

in the DayZ_Base file?

To my understanding, SideProxy is just client/server/bukkit. No choosing files. It will run the exact same code, but not run anything with @SideProxy(ClientSide) on the server.

You annotate a field with it, when the class is loaded that field will be populated with a instance of the class for the specific side you're running.

Is that to hard to get?

I had a look at how IronChest does it and made some changes. The server starts now but nothing in the client proxy is rendered in either the client or the server. I also noticed that in RenderingRegistry.instance().registerEntityRenderingHandler the .instance() comes out as deprecated.

Why the fuck are you int he minecraft package?

Mmk so I rage quit from this for a few days and ended up figuring it out. Turns out I may be slightly retarded since I didn't read correctly how to do the @SidedProxy. I did find though that I had to put

@SidedProxy(clientSide = "net.minecraft.src.DayZ_ClientProxy", serverSide = "net.minecraft.src.DayZ_CommonProxy")

when I worked out of MCP. When I reobfuscated I changed it to

@SidedProxy(clientSide = "DayZ_ClientProxy", serverSide = "DayZ_CommonProxy")

so all good now thanks for the help.

That will still not always work because you are in the net.minecraft.src package.

DO NOT BE IN THE 'net.minecraft.src' PACKAGE!

How Do I Commission A Mod

There typically isnt a place to commission mods. Mods are made by hobbyist programmers in their spair time. You could try some general minecraft modding discords, but I dont have any to recommend.

jarJar not working

minecraftLibrary is required for dev time for it to load.
jarJar should be enough for runtime.
be sure you're running the latest forge. And make sure you post your debug log.
