Entity Not Saving On World Unload

Recommended Posts

I have a new entity, but when I log out of the world, the entity despawns and isn't there when I come back in. I'm using the latest version of forge (I think) and MC 1.4.2.

 

EntityMech.java (without the pointless parts, only the important ones I think)

package nerdicus.fwc;

  Sorry about indentation issues :)

 

FutureWarCraft.java

package nerdicus.fwc; //Change this to your package

import net.minecraft.src.Block;
import net.minecraft.src.EnumCreatureType;
import net.minecraft.src.FurnaceRecipes;
import net.minecraft.src.Item;

import cpw.mods.fml.common.registry.EntityRegistry;
import cpw.mods.fml.common.registry.GameRegistry;
import cpw.mods.fml.common.registry.LanguageRegistry;

@NetworkMod(clientSideRequired=true, serverSideRequired=false)
@Mod(modid="FWC", name="Future Warcraft", version="Alpha v0.1")

public class FutureWarCraft
{
@Instance
public FutureWarCraft instance;

@Init
public void FWCInit(FMLInitializationEvent initEvent)
{
	EntityRegistry.registerModEntity(EntityMech.class, "FWCMech", EntityRegistry.findGlobalUniqueEntityId(), instance, 50, 50, true);
}

Again, sorry about any possible issues.

 

Any ideas? The entity spawns fine, but it just doesn't save itself. I just copied the boat code and modified it a little bit, but it's not working.

 

If you need any more of the code, I'd be glad to supply it. I've had this problem for about 1.5 months.
