[Solved]Mod Not Working On Server - LoaderException

[HoBoS_TaCo]

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;
import cpw.mods.fml.common.Mod.Instance;


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.

[LexManos]

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

[HoBoS_TaCo]

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();

[LexManos]

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

[HoBoS_TaCo]

DayZ_Base - I removed all the references to the items, blocks, .addName etc.

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.

[LexManos]

    	//Load the sound(s) in ClientProxy.
        DayZ_ClientProxy.loadDayzSounds();
        //Load the renderer(s) in ClientProxy.
        DayZ_ClientProxy.registerRenderInformation();

You have hard references to client proxy.

Thats bad, take a look at SideProxy

[HoBoS_TaCo]

       //Load the sound(s) in ClientProxy.
        DayZ_ClientProxy.loadDayzSounds();
        //Load the renderer(s) in ClientProxy.
        DayZ_ClientProxy.registerRenderInformation();

You have hard references to client proxy.

Thats bad, take a look at SideProxy

 

 

D:

 

 

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?

 

 

 

 

 

 

[werl]

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.

[LexManos]

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?

[HoBoS_TaCo]

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.

[LexManos]

They arnt getting loaded because "DayZ_ClientProxy" != "net.minecraft.src.DayZ_ClientProxy"

Why the fuck are you int he minecraft package?

[HoBoS_TaCo]

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.

 

 

[OvermindDL1]

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

 

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