Chremastics
by vortianski
Chremastics adds a Terraria-inspired money system to NeoForge, with four coin tiers, coin bags and configurable coin drops from mobs.
What it does
Money in Chremastics comes in four tiers: copper, silver, gold and platinum coins. Coins can be stacked into coin piles, and coin bags hold large sums so that a player does not have to carry hundreds of loose coins. Mobs drop coins on death, and the drop amounts, chances, entity whitelists and blacklists can all be set in the configuration.
The mod also replaces the usual emerald trades of villagers with coin-based trades when the option is enabled, which keeps trading inside one currency. A purse overlay on the screen shows the player's current balance. Chremastics is open source under the MIT License and is meant as a base that a server or modpack can extend toward a fuller RPG-style economy. The Curios API adds optional integration, and VortyLib is required.
Key features
Four coin tiers
Copper, silver, gold and platinum coins form a complete currency with fixed values between the tiers.
Coin bags
Coin bags store large amounts of money so a balance can be carried in a single item.
Configurable coin drops
Entities drop coins on death in amounts and chances that the configuration sets, with entity lists to include or exclude mobs.
Coin particles and purse overlay
Coin particles can be turned on, moved or styled, and a purse overlay on the screen shows the current balance.
