Developer API
Crafting Tweaks provides both a Java API for developers as well as customization through datapacks.
Both can be used to make crafting grids compatible with Crafting Tweaks. The data pack API is recommended for most cases - the Java API can be used for more complex dynamic crafting grids that cannot be represented in a data pack.
This guide will help you get started with the Crafting Tweaks API.
API Overview
You can learn about the available API methods on our GitHub repository.
A good starting point is the CraftingTweaksAPI
or CraftingTweaksClientAPI
class. They will allow you to register a CraftingGridProvider
to define crafting grids within a container menu, and optionally a GridGuiHandler
to customize the placement of the tweak buttons.
You can find an example of how CraftingGridProvider
is implemented for Vanilla in the VanillaCraftingGridProvider
class.

Implementing a Soft Dependency
Most likely, you will want to implement your Crafting Tweaks support as a soft-dependency to prevent your mod from erroring if the user does not have Crafting Tweaks installed.
The safest way of doing so is to load your Crafting Tweaks addon class only if the mod craftingtweaks
is loaded.
This should be done using reflection, as any direct reference to new YourCraftingTweaksAddon()
would cause Java to preemptively load the class even if the mod is not present.
Pseudo-code Example:
@Mod("yourmod")
public class YourMod {
public YourMod() {
// ...
if (ModList.get().isLoaded("craftingtweaks")) {
try {
Class.forName("net.yourmod.compat.YourCraftingTweaksAddon").getConstructor().newInstance();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
public class YourCraftingTweaksAddon {
public YourCraftingTweaksAddon() {
CraftingTweaksAPI.registerCraftingGridProvider(new YourCraftingGridProvider());
}
}
Adding Crafting Tweaks to your Development Environment
Using CurseMaven
repositories {
maven { url "https://www.cursemaven.com" }
}
dependencies {
// Replace ${craftingtweaks_file_id} with the id of the file you want to depend on. You can find it in the URL of the file on CurseForge (e.g. 5368374).
// NeoForge:
implementation "curse.maven:crafting-tweaks-233071:${craftingtweaks_file_id}"
// Fabric:
implementation "curse.maven:crafting-tweaks-fabric-547689:${craftingtweaks_file_id}"
// Forge after Minecraft 1.20.6:
implementation "curse.maven:crafting-tweaks-233071:${craftingtweaks_file_id}"
// Forge before Minecraft 1.20.6:
implementation fg.deobf("curse.maven:crafting-tweaks-233071:${craftingtweaks_file_id}")
}
CurseMaven is great for building against officially released versions, but it does not provide access to snapshot versions or common jars (mojmap) for multi-loader environments.
If you need access to those, you can use Twelve Iterations Maven instead.
Using Twelve Iterations Maven
repositories {
maven {
url "https://maven.twelveiterations.com/repository/maven-public/"
content {
includeGroup "net.blay09.mods"
}
}
}
dependencies {
// Replace ${craftingtweaks_version} with the version you want to depend on.
// You can find the latest version for a given Minecraft version at https://maven.twelveiterations.com/service/rest/repository/browse/maven-public/net/blay09/mods/craftingtweaks-common/
// Common (mojmap):
implementation "net.blay09.mods:craftingtweaks-common:${craftingtweaks_version}"
// NeoForge:
implementation "net.blay09.mods:craftingtweaks-neoforge:${craftingtweaks_version}"
// Fabric:
implementation "net.blay09.mods:craftingtweaks-fabric:${craftingtweaks_version}"
// Forge after Minecraft 1.20.6:
implementation "net.blay09.mods:craftingtweaks-forge:${craftingtweaks_version}"
// Forge before Minecraft 1.20.6:
implementation fg.deobf("net.blay09.mods:craftingtweaks-forge:${craftingtweaks_version}")
