Yeslan merchants:

Unlike other regions, in Yeslán it is very common for people to haggle over the value of things and even sell things at a higher price than normal.

In this case, I decided to separate the merchants into two camps:

Classic Merchant:

There is not much mystery in this type of merchants, they sell objects and the player can sell them the things they have, nothing more.

Traveling merchant:

They are people who have small businesses, it is possible to see them in tents or even standing with a rug selling things.

Unlike the classic merchant, they sell a specific item and buy some from the player at a higher price than normal.

Starting with the technician, it is possible with them to buy objects at the price they sell, in most cases they handle X number of units, it is not possible with them to buy the amount you want.

In the event that the player decides to haggle, they will have 5 options for offering an amount of money for X units of items they sell, there is even the option of making it free.

Each of the options is a reduction of X% of the value offered by the merchant... except for the free one.

This is easy, it starts with a 'money condition', this is based on the X amount of one of the options, after analyzing that the player has the required amount, a common event is started.

This common event is the successful probability of bargaining, each option from before has its own... that is, 5 common events with different probabilities.

Example:

Option A: 80% probability of successful haggling, 20% unsuccessful haggling.

-----------------------------------------------------------------

In the case of success, the player will be charged the amount of the selected option.

In the event that the haggling fails, the merchant NPC will become angry with the player and will not feel like trading with him.

This is only temporarily, this lasts depending on the option.

Example:

Option A = 1 minute

Pleasant option = 3 minutes

After time passes, the merchant NPC will return to normal and it will be possible to trade with him again.

Sell:

In the case of selling, many NPC merchants do not accept to buy the player's things, so it would not be possible to sell items to them.

But there are some that it will be possible to sell things to them, that is, these NPC merchants are looking for a specific object, for which they will buy for X units from the player, mostly higher than the price of these objects.

Example:

5 units of chile (Global value) = 100 coins

5 units of chile (Merchant value) = 120 coins

There is also the possibility of haggling the price of the NPC merchant, this so that the player obtains more profits than the NPC would expect.

Of course, just like haggling when purchasing, this works the same, only the probability of failing is slightly higher.

-----------------------------------------------------------------

This is where it ends, sometimes I like to teach these kinds of things, not so much as a guide or something I did, simply to show something that I did and I would like to show it to the community.

Also, thank you very much for your attention !
