Different functions in the same blueprint giving different variables?

So I guess my plan from here is to drop the project and come back to it later after I have a bit more understanding. Though, these replies have raised a few more questions!

Keep going. Was not talking about your stuff…

When should I use functions over events? These are functions because they’re called in different blueprints that all give different variables. I just assumed functions could be called in separate blueprints while events couldn’t. Although to be fair exactly what allows blueprints to communicate with each other is still a bit of a mystery.

Basically, if you have to do something - event. If you need to compute something and get a value back - function. Functions are used to DEATH on utube, where they are doing the job of a custom event. You can reach functions remotely just like custom events, it’s not really anything to do with that.

Also, if the function makes changes and gives a value back, technically it needs an execution path ( in and out connectors ), and if it just figures something out, it can be ‘pure’

which means you can use it like this

Checking the inventory: GREAT example of when to use a function. You give it the name, and it gives you back a bool
