In an attempt to add a new value for EnumCreatureType, Minecraft crashed. The line adding the type is:

 

public static final EnumCreatureType ambientWater = EnumHelper.addCreatureType("ambientWaterFish", EntityWaterMob.class, 40, Material.water, false);

 

Here is a link to the Crash report: https://gist.github.com/Azaka7/9679277

 

I originally encountered this problem when modding for MC 1.6.4, and had hoped it was fixed for 1.7.2, but that's not the case. It's the same crash for both versions. I have been looking around the coding and I see no reason why this would cause a crash, but creating a custom armor material would not. It appears that Forge is feeding the constructor 2 unnecessary arguments.

 

My reason to create this creature type is to be able to populate the ocean with very basic fish without spawn rates limited to that of squid and lobster (lobster is a water-type creature I've created).

 

Does anyone know why this is happening? Do I need to do something different for custom creature types, or should I report this as a bug with Forge?

Actually, Forge is missing an argument (isAnimal).

Just use this:

private static final Class<?>[][] paramTypes = new Class[][] {{EnumCreatureType.class, Class.class, int.class, Material.class, boolean.class, boolean.class}};
public static final EnumCreatureType ambientWater = EnumHelper.addEnum(paramTypes, EnumCreatureType.class, "ambientWaterFish", EntityWaterMob.class, 40, Material.water, false, true);

instead of:

public static final EnumCreatureType ambientWater = EnumHelper.addCreatureType("ambientWaterFish", EntityWaterMob.class, 40, Material.water, false);

 

The last parameter, as previously suggested, means isAnimal. Set it to true/false accordingly

Oh, wow! Thank you very much. I guess I just didn't see that there were supposed to be two booleans.
