Trader profile

0. Overview

Let's explore abstract simplified trader profile trade_bandit.ltx:

#include "presets\trade_discounts.ltx"
#include "presets\trade_presets.ltx"

[trader]
buy_condition = {=actor_goodwill_ge(bandit:400)} trade_generic_buy_everything, trade_generic_buy
sell_condition = {=actor_goodwill_ge(bandit:400)} trade_generic_sell_everything, trade_generic_sell
buy_supplies = {=actor_goodwill_ge(bandit:400)} supplies_2,  supplies_1
buy_item_condition_factor = 0.40
buy_item_exponent = 2.25
sell_item_exponent = 0.75

discounts = discount_trasher

[trade_generic_buy]
jgut = 0.1
toolkit_r5

[trade_generic_buy_everything]

[trade_generic_sell]
toolkit_r5

[trade_generic_sell_everything]
toolkit_r5 = 0.5

[supplies_1]
toolkit_r5 = 2, 0.1

[supplies_2]:supplies_1
toolkit_r5 = 3, 1

1. buy_condition

Defines list of items trader won't buy or price modifier of those he buys

Accept a condlist of sections of items. Those items should follow one these rules:

jgut = 0.1 means trader will buy jgut item for 10% of it's price. Related script
toolkit_r5 means trader won't buy that item at all

To conclude, this:

buy_condition = {=actor_goodwill_ge(bandit:400)} trade_generic_buy_everything, trade_generic_buy
[trade_generic_buy]
jgut = 0.1
toolkit_r5

[trade_generic_buy_everything]

means trader will

if goodwill >= 400 buy all items at 100%
if goodwill < 400 3) buy jgut for 10% of its price 4) won't buy toolkit_r5 at all

2. sell_condition

Same as 1. buy_condition but for selling items to actor

3. buy_supplies

Defines what items trader have in stock

Accept a section of items. Those items follow simple rule:

[supplies_1]
toolkit_r5 = 2, 0.1

[supplies_2]:supplies_1
toolkit_r5 = 3, 1

Trader have 10% chance to add 2 toolkit_r5 to his stock. If count > 1 then chance is calculated for each item separately

0. Author note

It's important to distinct sell_condition from buy_supplies:

sell_condition - define at what condition which items trader will sell to actor

buy_supplies - define what items trader have in stock

So you can combine these options to create complex trader profiles.

4. buy_item_condition_factor

Trader will buy items that have condition greater or equal to buy_item_condition_factor

5. buy_item_exponent, sell_item_exponent

Defines how steeply the item's price drops with condition loss Anomaly uses this in its formula to decide final price for an item:

cost * discount * math.pow((cond * 0.9 + 0.1), exponent > 0 and exponent or 0.75

Basically, the higher value, the lower the final price for items with condition < 1

6. discounts

Defines buy/sell discounts for trader

Accepts section with specific properties:

[discount_barman_special]
buy                                      = 0.2
sell                                     = 0.7

This means trader will buy items for 20% of their price and sell for 70% of their price Common discounts are defined in presets\trade_discounts.ltx
