[Scripting Question] How to increase your Pokemon IVs?

I want to create an item that increases a selected Pokemon IVs, similar to the golden caps in S/M.

Is this possible?

Thanks for the answers.

A gold bottle cap is just an item that you give to a guy to raise the IV's, if I'm not mistaken. If that's the case it would something like an event that tell you this

pbChoosePokemon(1,2,
proc {|poke|
!poke.egg? &&
!(poke.isShadow? rescue false)
})

Click to expand...

p=pbGetPokemon(1)
p.iv[0]=31 #HP
p.iv[1]=31 #Attack
p.iv[2]=31 #DF
p.iv[3]=31 #Speed
p.iv[4]=31 #S.Att
p.iv[5]=31 #S.Df
p.calcStats

If you want an item that, from your bag, increase the IV's, just copy the way the vitamins works with the ev's just changing it to the iv's
