Scripts don't seem to work at all

Unity Engine
1

Edited: Solved by creating an empty game object and placing single script file into said game object, but how do I go about placing scripts that work with other scripts in subfolders into a game object?

All of my scripts are listed under ‘Assets’ in the folders that they were imported to. I’ve tried multiple scripts from the Asset Store such as

Pause Menu:

Inventory

They don’t work in the Unity Editor or the built project that I build and run. Pause menu is supposed to activate when I hit the ‘escape’ key but nothing displays, and Inventory is supposed to display a GUI when I hit ‘i’ but again nothing displays. I also followed a small RTS camera tutorial to the T and even though it worked for the tutor, it didn’t seem to work for me. Am I missing something? For example, here is the code for the pause menu so you don’t have to download it yourself:

Generally speaking, a script you create is an extension to monobehaviour. You’re writing components which are placed on game objects to run.

I’d suggests doing some tutorials and learning the fundamentals of unity.

Hi there, I’d recommend you have a look at this to answer some of your questions regarding scripts.
And highly recommend going through as much as you can here.
Scripts in your project view (where you imported some examples) will not do anything, they are technically not in your game yet. You have to attached them to a gameobject in your game/scene, whether its a health script attached to your player or an inventory system which is attached to an invisible gameobject anywhere in your scene.
Good luck!
