ZenExpansion

A ZenExpansion is, like @ZenClass, used to annotate a Class that should be accessible from within ZS.
Unlike ZenClasses however, ZenExpansions are used to expand the functionality of already existing ZenClasses.

java
 Copy
@ZenExpansion("crafttweaker.item.IItemStack")
@ZenRegister
public class Expansion {
    @ZenMethod
    public static void print(IItemStack stack) {
        CraftTweakerAPI.logInfo("STACKKKKK: " + stack.getDisplayName());
    }
}

This would allow people to do

ZenScript
 Copy
<minecraft:iron_ingot>.print();

Since this is an expansion the first parameter is the class' instance!
This parameter will not be available in ZS.

• All Methods need to begin with a parameter that represents the expanded class' instance. Also, all Methods inside the expansion must be static (... and public).
• You can annotate all Java Classes
• You must give the annotation a String value (e.g. crafttweaker.item.IItemStack). This String value must represent an already existing ZenClass' name.
• After declaring a class a ZenExpansion, you still need to register it. It is recommended that you use @ZenRegister for that.
