One Enough Value

Each item can carry a value, and an item with no assigned value shows 0. Base values for the most basic materials come with the default data, and other values can be changed by the methods the mod documents. Adding or subtracting a number moves the value up or down, so 0 becomes 10 after a +10 change, negative numbers are accepted, and fractional results are rounded down, turning 0.5 into 0.

Crafting drives most of the values. A recipe's output is worth the summed value of its ingredients by default, so a red dye crafted from a red tulip carries a value of 16, and the default gold ingot is set to 648. When a recipe yields more than one item, the value is divided across the quantity. Vanilla recipes use this plain summation method, and a simple template can make a crafted item worth ten times its ingredients. Other mods can register new recipe types and set up the same summation.

The mod requires KubeJS as a prerequisite. Other mods that need to read item values at runtime use the Value Manager interface. The source code is public under the GNU General Public License v3.0 only, so the code is open source, and the mod is published for Forge.
