Hello, when trying to spawn my entity into the world with;

ModLoader.addSpawn(EntityHorse.class, 4, 1, 3, EnumCreatureType.creature);

in my load method

 

I get this error;

I believe it's because the World is not getting passed through the constructor of EntityHorse, why would this be? here is EntityHorse.class;

You have to make a constructor with only the World parameter, like this:

 

public EntityHorse(World par1World)
{
    super(par1World);

    // YOUR CODE
}
