WeightedItemStack

A Weighted Item Stack is like a normal IItemStack but has a percentage added to it.
You normally use them when dealing with percentage based actions like drops or secondary outputs.

Importing the package

It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import.
import crafttweaker.item.WeightedItemStack;

Implementing IWeightedIngredient

WeightedItemStack implements IWeightedIngredient. That means all functions available to IWeightedIngredient also are available to WeightedItemStack.

Calling a weightedItemStack

You can derive a weightedItemStack from an IItemStack by either using the modulo operator or the weight function on it.

val itemStack = <minecraft:dirt>;

//both create a weightedItemstack object with a chance of 20%
val wItemStack = itemStack % 20;
val wItemStack2 = itemStack.weight(0.2);
