My items only set default config values when registering. I think this is due to the fact that they are registered before the config is updated. This is true?

If so, how exactly do I need to rearrange the code so that everything works correctly?
Thanks in advance for your help!

That is correct, registration must not depend on config files so that servers work properly.

I need the characteristics of items to depend on the numbers in the config (damage, for example).  Is it possible?

Yes, that is possible, however you must store those in a config of type SERVER and read them on the fly when they are requested. Otherwise the server's config data will not influence the client and lead to buggy behavior.

What does "read them on the fly" mean?  If I register a config of the correct type and in the registration class of the item I take the number of damage from the config, will this not work?

No, it will not. You must always read the values from the config file as they are needed, you cannot store them anywhere else. This is because the player might connect to different servers which have the value configured differently and your code must still work. Registration of items however only happens once at startup and would not support this use-case.

can you show me the specific code i need for the item to have a value from the config when registering?
At the moment I'm taking the value like this, but it doesn't work.
 

public float getAttackDamage() {
				return ModConfig.ServerConfig.northernStarDamage.get().floatValue();
			}

Show your whole item class, where you register the Item as well as your config code.
