KeepInventoryShop v3.0.2 Changelog

New Features

Multi-Currency Support

Players can now pay for lives and upgrades using three different currencies:

• Server Economy (default): Uses your Vault-compatible economy plugin
• Emeralds: Pay with emeralds from your inventory
• XP Levels: Pay with experience levels

How it works:

• In the Buy Lives and Upgrade GUIs, the top row now shows currency selector buttons
• Click a currency to switch to it (selected currency is highlighted)
• The cart and confirm button automatically update to show costs in your selected currency
• Costs are calculated relative to the money price using configurable exchange rates

New Config Options:

# Allow players to pay with emeralds instead of money
allow-emerald-payment: true

# Allow players to pay with XP levels instead of money
allow-xp-payment: true

# How much money 1 emerald is worth
# Example: If emerald-value is 100 and cost-per-life is 500, one life costs 5 emeralds
emerald-value: 100

# How much money 1 XP level is worth
# Example: If xp-level-value is 50 and cost-per-life is 500, one life costs 10 XP levels
xp-level-value: 50

Server owners can disable either alternative currency by setting allow-emerald-payment: false or allow-xp-payment: false.
