advice structuring code

[limber elbow]

i am building an inventory and a building system. it would be easier if i make the building system inside in the inventory script but the script gets super long and its hard to find my way in it.should i keep these systems in different scripts?

[tranquil cypress]

they should definitely be separate

i dont see how they are at all related

as long as you are using modulescripts, you can still have them reference each other
