I am trying to use one class for handling all the available NBT instances of an item along with the models that will get generated by each NBT instance (dynamic items with dynamic models).

This is the code I have so far:

public final class DraftableReg {

private static HashMap<String, IDraftable> knowledgeBase = new HashMap<String, IDraftable>();

@SideOnly(Side.CLIENT) //this is line 24
private static HashMap<String, DraftableBakedModel> models = new HashMap<String, DraftableBakedModel>();

public static void RegisterDraftable(IDraftable draftable, World world){
	if(world.isRemote){
		LogHelper.info(draftable.GetName() + " registered by Player");
		models.put(draftable.GetName(), new DraftableBakedModel(draftable));
		;//send draft to server for registry
	}
	else
	{
		LogHelper.info("Registering Draftable :" + draftable.GetName());
		knowledgeBase.put(draftable.GetName(), draftable);
	}
}
}

 

This is fine when I am running in an Integrated server but it fails when I try to launch a dedicated server.

This is the chrash:

java.lang.NoSuchFieldError: models

is there a reasonable way for me to do this in one class or will I have to make a clientside only class that handles models?

http://www.minecraftforge.net/forum/index.php?topic=22764.0

So what I am getting out of that is that I need to make a separate class that will only get accessed by (logical) client side code.

If the field is marked by @SideOnly, it can only be referenced by @SideOnly method.

You can have Class with both SERVER and CLIENT methods/fields, but they cannot cross reference each other.

 

Then: If your method is SideOnly, it cannot be referenced by any other common method, thus - you always need to make all your calls by Proxy.

 

Design choice:

CommonClass {
     Map serverLogicalDraftable; // common map for server-logical registry
     register(IDraftable, World) {
        if (world.isRemote) proxy.registerClientDraftable(IDraftable)
        else serverLogicalDraftable.put(name, IDraftable);
    }
}

Proxy part:
CommonProxy {
    registerClientDraftable(IDraftable) {
        // Do nothing
    }
}

ClientProxy {
    Map clientOnlyDraftables;
    registerClientDraftable(IDraftable) {
        clientOnlyDraftables.put(name, IDraftable);
    }
}

 

Then you can do similar with getters.

Well this is going to be tiresome to switch up ... oh well, Thanks for the help!
