As we all know, it's possible to target special Entities in  Minecraft 1.8 using the

@e[type=Entity]

selector.

However, there is a problem with modded Entities. The name of those Entities is not compatible with the method because it contains a dot.

That's because Forge adds the Modid to the name. An Entity called MagicArrow, for instance, will get the Name weaponmod.MagicArrow.

This is caused by the registration method EntityRegistry.doModEntityRegistration:

 

private void doModEntityRegistration(Class<? extends Entity> entityClass, String entityName, int id, Object mod, int trackingRange, int updateFrequency, boolean sendsVelocityUpdates)
    {
        ModContainer mc = FMLCommonHandler.instance().findContainerFor(mod);
        EntityRegistration er = new EntityRegistration(mc, entityClass, entityName, id, trackingRange, updateFrequency, sendsVelocityUpdates);
        try
        {
            entityClassRegistrations.put(entityClass, er);
            entityNames.put(entityName, mc);
            if (!EntityList.classToStringMapping.containsKey(entityClass))
            {
                String entityModName = String.format("%s.%s", mc.getModId(), entityName); //HERE THE NAME IS ASSIGNED
                EntityList.classToStringMapping.put(entityClass, entityModName);
                EntityList.stringToClassMapping.put(entityModName, entityClass);
                FMLLog.finer("Automatically registered mod %s entity %s as %s", mc.getModId(), entityName, entityModName);
            }
            else
            {
                FMLLog.fine("Skipping automatic mod %s entity registration for already registered class %s", mc.getModId(), entityClass.getName());
            }
        }
        catch (IllegalArgumentException e)
        {
            FMLLog.log(Level.WARN, e, "The mod %s tried to register the entity (name,class) (%s,%s) one or both of which are already registered", mc.getModId(), entityName, entityClass.getName());
            return;
        }
        entityRegistrations.put(mc, er);
    }

 

 

The dot in the name is not accepted by the @e selector. "

@e[type=weaponmod.MagicArrow]

" replies with the Error Message "The Entity UUID provided is in an invalid Format".

 

My suggestion is very simple:

Just change the dot to either an underscore or to nothing.

weaponmod_MagicArrow would be accepted.

Why would this break other mods? It would just change a single symbol in the Entity names!

Dang..

Yes, you're right. I missed that.

In theory the names should be : seperatoed, but its simple enough to make this command allow for the .'s

Better then nuking everyones world....

Thanks a lot! Which Forge Version will include this?
