|---|---|---|
| PlaceholderAPI | ✅ Required | Provides the %gemengine_...% placeholders |
| Vault | ❌ Optional | Automatic detection of installed economies (e.g. Essentials) |
? Files
config.yml – Configure Economies
This is where all currencies managed by the plugin are defined.
economies:
gems:
name: "Gems" # Display name of the currency
allow-pay: true # Can players transfer to each other?
coins:
name: "Coins"
allow-pay: falseTip: If Vault + Essentials are installed, an entry for the Essentials economy will be generated automatically on server start — no manual setup required.
data.yml – Player Data
All player balances are stored here. This file is managed automatically and should not be edited manually.
#Example
550e8400-e29b-41d4-a716-446655440000:
gems: 150.0
coins: 320.50?This was replaced by a database in newer versions.
? Commands
/gpay <economy> <player> <amount>
Transfers an amount of a specific currency to another player.
| Argument | Description |
|---|---|
<economy> |
The economy key from config.yml (e.g. gems) |
<player> |
Name of the target player (must be online) |
<amount> |
The amount to transfer (must be positive) |
Example:
/gpay gems Steve 50⚠️ Transfers must be enabled per economy in config.yml via
allow-pay: true. The sender also needs a sufficient balance.
/gemengine eco <set|add|remove> <economy> <player> <amount>
Admin command for manually managing player balances.
| Action | Description |
|---|---|
set |
Sets the balance to a specific value |
add |
Adds an amount to the balance |
remove |
Deducts an amount from the balance (minimum 0, no negative balance) |
Examples:
/gemengine eco set gems Steve 500
/gemengine eco add coins Steve 100
/gemengine eco remove gems Steve 25? Permissions
| Permission | Description |
|---|---|
gemengine.admin |
Access to /gemengine eco |
? Placeholders (PlaceholderAPI)
The placeholder format is:
%gemengine_<economy>%The <economy> part corresponds to the key defined in config.yml.
Examples:
| Placeholder | Returns |
|---|---|
%gemengine_gems% |
The player's balance in the "gems" economy |
%gemengine_coins% |
The player's balance in the "coins" economy |
Values are always returned with 2 decimal places, e.g.
150.00
? Vault Integration
If Vault is installed alongside an economy plugin such as EssentialsX, GemEngine will automatically detect it on startup and add a matching entry to config.yml.
Example: EssentialsX is installed and uses Dollars as its currency.
On the first server start, the following will appear in the console:
[GemEngine] Vault Economy 'Essentials Economy' detected!
[GemEngine] Entry 'essentials_economy' has been automatically added to config.yml.
[GemEngine] Placeholder: %gemengine_essentials_economy%The config.yml will then be automatically updated with this entry:
economies:
essentials_economy:
name: "Dollars"
allow-pay: falseNote:
allow-payis intentionally set tofalseto prevent accidental transfers from being enabled. This can be changed manually inconfig.yml. For more help and explanations look in theconfig.ymlandmessage.yml.
