I am trying to make my first entity ( 1.8 )  but when I run the client I get this message:

 

"java.lang.IllegalArgumentException: Can not set static com.kingarthur.elementalswords.ClientProxy field com.kingarthur.elementalswords.ClientProxy.modInstance to com.kingarthur.elementalswords.Main"

 

This is the relevant code in my client proxy:

 

public class ClientProxy extends CommonProxy {

 

@Instance(Main.MODID)

public static ClientProxy modInstance;

 

@Override

public void preInit(FMLPreInitializationEvent e) {

super.preInit(e);

}

 

@Override

public void init(FMLInitializationEvent e) {

super.init(e);

ModEntities.mainRegistry();

ItemRenderRegister.registerItemRenderer();

}

 

And this is the code in my ModEntities file:

 

public class ModEntities {

 

public static void mainRegistry() {

registerEntity();

}

 

public static void registerEntity() {

 

                createEntity(EntityFireGuardian.class, "Guardian of Fire", 0xF20505, 0xD8DE31);

}

 

public static void createEntity(Class entityClass, String entityName, int solidColor, int spotColor) {

 

                int randomId = EntityRegistry.findGlobalUniqueEntityId();

 

EntityRegistry.registerGlobalEntityID(entityClass, entityName, randomId);

 

EntityRegistry.registerModEntity(entityClass, entityName, randomId,

                ClientProxy.modInstance, 80, 3, true);

 

createEgg(randomId, solidColor, spotColor);

}

 

private static void createEgg(int randomId, int solidColor, int spotColor) {

 

                EntityList.entityEggs.put(Integer.valueOf(randomId), new EntityList.EntityEggInfo(

                randomId, solidColor, spotColor));

}

}

The field with the

@Instance

annotation needs to be the same type as your main mod class (the one with the

@Mod

annotation), since it holds the instance of that class.

 

Why are you doing this in

ClientProxy

? Entities need to be registered on both sides.

 

There's no reason to use global entity IDs (

EntityRegistry.registerGlobalEntityID

) or manually add spawn eggs in 1.8, if you need a spawn egg just call the

EntityRegistry.registerModEntity

overload with the two extra

int

parameters (the background and foreground colours of the egg).
