As you surely already messed a bit with variables and values, you must’ve wondered, how CraftTweaker knows whether it’s dealing with an Integer, an Item or an oreDic entry?
The easiest way of declaring a variable is using
var name = value;. This creates the variable and casts it to the value it thinks is most fitting for the situation.
Casting a variable to a specific type
More complex scripts might require you to cast a variable as a specific type. For example, this would fail:
var test; test = <minecraft:dirt>; recipes.remove(test);
So why does this fail? This is because CT casts variables that aren’t given a start value to the IAny Type. That type was made to facilitate some recipe handlers, though never really implemented, so it sometimes does more harm than good. It was originally intended as a type that can take the form of most other types so you don’t need to change variables all the time, but the interface never got implemented.
Back to the topic: How can we fix this issue? By casting the variable test to
IItemStack, which is the type used for items. Unfortunately, some types need to be imported first, and this is one of those.
import crafttweaker.item.IItemStack; var test as IItemStack; test = <minecraft:dirt>; recipes.remove(test);
List of Variable Types
Here’s an (incomplete) List of most variable types
|Name (Name in CT)||Explanation||Example||Import|
|Integer (int)||Integers are whole Numbers (e.g. 1,2,3,…), caps at 2 147 483 647||
|IIngredient||Single or Multiple Items (e.g.
|IOreDictEntry||Multiple Items from an OreDict (e.g.
|Boolean (bool)||Booleans are either true or false.||
|Byte (byte)||Bytes values are whole numbers from 0 to 255 ()||
|Floating Point (float)||Decimals||
|Double Precision (double)||Like Floating Points, just more precise and with a higher number range||
|Long (long)||Like Integer, but with a higher number range (usually int is just fine)||
|Null (null)||Null, nothing, nada. Not really a type but still useful||
|Short (short)||Like Integer, but with a smaller number Range||
|String (string)||A string is a text. Here you usually won’t need the “as” as anything in “s is automatically a string.||
|Void (void)||Even less than null. You will probably only need the void type when dealing with functions||
|ILiquidStack||Same as IItemStack, only for liquids||
