well u know how we can giv dolls to each other? yeah maybe the trading system should work like that? but you dont need to pay of course. My idea goes something like this:
PERSON1: (taps 'trade' button)
"type the name of the person you want to trade with"
PERSON1: (types name 'PERSON2')
"confirm?
PERSON1: (taps 'confirm')
PERSON2: (gets a message saying: PERSON1 would like to trade their ______, do you accept?)
PERSON2: (taps 'accept')
"what would you like to trade in return?"
PERSON2: (chooses item or itemS from inventory. Taps "TRADE")
"ARE YOU SURE YOU WANT TO TRADE THE ITEM/ITEMS FOR PERSON1's ITEMS?(SHOW PICTURES)
PERSON2: (taps 'confirm')
"YOU CONFIRM THAT YOU WANT TO TRADE?"-message to both players
PERSON1: ('CONFIRM')
PERSON2: ('CONFIRM')
"YOU HAVE SUCCESSFULLY TRADED!"
