Points or gains? Gains and points are different things, you’ll need to use points specifically if you want the outfit choice to have confirmation.
Similarly to what’s used in dara.amarie.ep’s tappable dressing game templates. If you’re not using MC points, you can add to your MC’s totals (by using @MC = outfit#ofpoints).
Then later you’d do…
if (MC =1) {
@LYDIA changes into partyoutfit1
} elif (MC =2) {
@LYDIA changes into partyoutfit2
} elif (MC =3) {
@LYDIA changes into partyoutfit3
} elif (MC =4) {
@LYDIA changes into partyoutfit4
}elif (MC =5) {
@LYDIA changes into partyoutfit5
}
If you’re using character points for your MC, I’d just make a new character just for outfit remembering
