Introduction
This plugin allows you to change the prices of shops during the game, globally or just for a specific shop, which can be useful for friendships and such things.
Features
- Create price changes for items sold by shops, globally or on a per-shop basis.
- Create price changes for items sold by the player, globally or on a per-shop basis.
- Global rule taken in account even if there is a rule specific for the shop, and applied after it.
- Only one global rule, creating another one will erase the previous one.
After installing the plugin, everything is set up, you just need to use plugin commands!
Reduction ADD:
This command allows to change the price of items sold / bought.
Usage: Reduction ADD <shop> <action> <formula>
Shop: can be either global, this or the id of the event that will show the shop.
“global” is used to change the prices of ALL the shops, and is applied after the per-shop price modifications.
“this” is a shortcut that targets the current event.
If you use the id of the event, you should also specify the id of the map. (e.g. 4 1 will target the event with id 4 in map with id 1)
Action: can be either BUY or SELL.“this” is a shortcut that targets the current event.
If you use the id of the event, you should also specify the id of the map. (e.g. 4 1 will target the event with id 4 in map with id 1)
“BUY” will change the prices of the items the player will buy.
“SELL” will change the prices of the items the player will sell.
Formula: the formula to apply when changing the prices.“SELL” will change the prices of the items the player will sell.
You can either add a predefined price or add a percentage.
e.g. “+5%”, “-10” will respectively add 5% to the price or remove 10 to the price.
e.g. “+5%”, “-10” will respectively add 5% to the price or remove 10 to the price.
Examples:
- Reduction ADD global BUY +10% will increase the prices of all items sold by shops by 10%
- Reduction ADD this SELL -10 will reduce the prices of all items sold by the current event by 10G (or whatever currency you use).
- Reduction ADD 14 3 BUY +10% +5 will increase the prices of all items sold by the event with id 14 in map with id 3 by 10% then add 5G more.
- Reduction ADD this SELL -10 will reduce the prices of all items sold by the current event by 10G (or whatever currency you use).
- Reduction ADD 14 3 BUY +10% +5 will increase the prices of all items sold by the event with id 14 in map with id 3 by 10% then add 5G more.
Warning:
