Hi,

So I have a bunch of mods, but would like to tweak them a bit.

What I did I created a simple mod with dependencies on the mods I want to tweak.

Example: one mod adds higher tiers of modules. I want to tweak their effects, for example, make bonuses the same as vanilla, but make penalties a bit smaller, to justify the cost.

I already know how to refer to base files: for example.

However, how do I refer to the modules being added by one of the dependent mods? The mod adds for example "productivity-module-4".

If i try to refer to it as above then upon loading I get an error, that this line return "nil", eg. this entity does not exist.

Any tips?

Thanks in advance.

The obvious one is to check that its name really is productivity-module-4.

The next thing I'd check is the part of the data lifecycle it's being defined in the depended-on mod - is it at the data, data-updates or data-final-fixes stage? If your depended-on mod is doing it in data-updates then you can't modify it any earlier than data-updates yourself because it won't exist yet, ditto data-final-fixes.

That's it.

The referenced mod added the entity in data-updates stage.

For future reference: solution is to set the dependent mod to load files in same or later stage as well.

Thank you!
