Relic Castle

I'm probably not the first one to ask here, but I was wondering if there's a way to create an event that tells you the exact EVs and/or IVs of one selected Pokemon.

I was looking through scripts and found a Hyper Training script, and in the screenshots it had an NPC that said a selected Pokémon's IVs. The event wasn't publically provided, though.

And no, I'm not asking for a way to display a Pokémon's EVs and IVs in the summary menu.
