I'm not* certain what you mean? But yeah, VX's conditionals do support checking items. I mean, they can't really check to see if you have ALL the items in the game? if that's what you mean, because if that's what you want, then I would say 'have fun' because you'll be using a shit ton of conditional branches checking each individual item in the inventory of a player. The only easy way I could think of (since im still assuming what you're asking) is to give the player one more item as like some sort of achievement for gathering every single item in their inventory or something, then you only have to make one conditional to check if that one item is in their inventory. I still don't really know what you're asking for, but i hope this helps a bit.
