First thanks to all, the opinions are important!
I'll try to be specific with answers, I hope you understand, otherwise comment me again and explained.
The game Allows four windows (0,1,2,3) at the same time, very difficult to manage.
0 -> Ask for approving price Cloud (also see your GP)
1 -> People and seller
2 -> Cloud window (numeric price)
3 -> Numeric bid
The fun in this minigame also in "observation", you have to see if people will not bid at that time, otherwise, if
your offer later and be less (or equal) is canceled, if you do that you can not try the latest offer.
Example of interfering bid:
Bidder offer first (200)
You can offer after having several cases
If it is equal or less (= 200 or <200) then (surprise, look at animation) and cancel your bid.
If bid / offer very afternoon and new stored value, then your character may not attempt to offer (if equal to or lower).
The reason to continue moving your bid is prepared to offer in case of another time immediately after higher price,
when the variable then takes on new value (after amount) you can new offer.
NFITC1 I can add to Cloud indicator window "be your last bidder" you asking for it? but you may know, if you just comparing numerical value equals vendor bid.
Ofcourse, NPC have intelligence, example for that reason some do not bid at any time (not interested), everyone has to ask the ID code of the item on auction, also time of auction.
First and really important is the stable functioning of auction, then I will give the most vibrant personality, examples of the future:
They decide to try or not to bid depending on the total number of bids.
They decide to try or not to bid depending on the maximum bid value.
They decide to try or not to bid again depending on whether cloud bid with them (then they upset / angry).
They decide to try or not depending on luck bidding.
They decide to try or not depending on gamemoment bid.
They decide to try or not to bid depending on the leader (eg do not bid if Johnny be above Tifa XD).
They decide to try or not depending on whether bid won an auction before.
They decide to try or not to bid depending on other conditions.
I accept suggestions
The auction has a total of more than 50 different items, 30 independent auctions (with random exceptions), again depending on the auction gamemoment be better, but very important part above, new gamemoment other items but also ask auction number, if you exceed 30 auctions following be totally random.
The sale magic level can have a "random" (spirit + magic example can be in level 2 or 3)
Also for new auction have to wait 30 minutes for this auction Also be totally in real time.
We have several cases for the seller to end auction:
Exceed the maximum value of article
If the question does anyone give more? if no new price offer.
If seller assign fixed value to sell and no thriving put new price then sell for above price, otherwise new value
I hope you understand
