Hello i want to know if its possible to know who redeem the coupon code
if a player redeemed already that code he will get a message "u already redeemed this code"
and if he didnt but someone else already redeem it they the player will get "someone else already redeemed that code"
also another question can i make a player to unclaim that redeem code to let other players redeem it ?
(im trying to make card game with qr codes , that are coupons codes printed as qr codes.
so when a player redeem a code he will get an item and he can trade this item, with the coupon code.
as if the trade the coupon code itself with another user.
lets say i have a card item "sword" i want the player to scan it redeem the sword.
later on upgrade that sword ,and each time the user wants to use that item he must scan it
if he already scanned this code and the sword is in his inventory then he can use this sword.
so if he trade it with someone else i want the other player to be able to use the coupon code too
cuz its part of this item the coupon code and the item are always together.
(item instance id and the coupon code always together).
