Add "has nbt" requirement type

[BlitzOffline]

It was suggested in the HelpChat Discord server that we add a new requirement type that would allow menus to check if specific NBT tags are set, what value they have, etc.

We would have to first decide if this is a good idea or not and then what are all the features this will add and how they will look like.

With the CheckItem Expansion, id regard this feature as pretty redundant to implement and unnecessary workload.

This would be unrelated to items. Talking about NBT data for players.

I also just noticed the ScoreboardTags expansion on the ecloud, and this seems like it could be easy to implement.
I just tested the expansion, and it works; for those of you that want to implement it in your menus before it (possibly) gets implemented into deluxemenus

The initial idea was to add the requirement for items. I didn't even consider it might also be used for other stuff such as players.

I am still not sure if this is a good idea or not. We have been trying very hard to remove any unnecessary NBT usage from DeluxeMenus.

Work on a proper API is also going to begin soon (hopefully) so this issue might be irrelevant then.

Oh I see. The user in discord was wanting to check if a player had an NBT tag, not if the player had an item with an nbt tag with a specific value.

Either way, right now both of these things can be done with the CheckItem/ScoreboardTags expansions.
