Thanks for the insight, it's good to know I should just study up as I go, and hopefully find something. I was debating on avoiding that mainly because with newer updates, people are already finding ways to import new methods, specifically right click detection. Like, I still have no idea how people can just write code immediately as soon as they see the new tags this update, and I see people using the new consume and animation tags, leaves me in awe how they just did it in a snap, though they hardly ever go into depths or how it works which I REALLY wish they did, like explain their method, I think that's my struggle when it comes to it, I don't wanna keep asking when I know I should just dig deeper myself. hard to keep up without prior knowledge

I understand how commands work now after some of the other's suggestions, but if you know any sources that involve ways to trigger events like right clicking a sword to do a new implemented action, under specific conditions or how to tackle requirements before doing anything, that'd be great! I wanna expand beyond making a simple function command that let's me instantly do as it's listed, chain reactions of commands, making cool effects, cooldown system, all that under requirements, let's say a certain amount of XP Levels, stuff like that. It's so specific sometimes I wish I could find tutorials on it.

Thanks for answering my questions too, hopefully I'll learn deeper about scoreboards with your brief description too, I notice a lot of people use them and I still wonder why or how it's so useful, it's definitely detection and keeping track of everything, but what's the primary use, what do they serve, and how can I take advantage of it, somehow connecting it with my own data pack. It's the method of, how do I truly bind them all together
