Recipes

Create machine recipes using KubeJS

Custom Machine recipes can be made with KubeJS.

Create a .js file in the kubejs/server_scripts/ folder (ex: custom_machine_recipes.js).

Then inside the .js file you can use the recipes kubejs event to get the custom machine recipe builder, pass it the id of the machine you want to make the recipe for and the duration of the recipe (in ticks).

onEvent('recipes', event => {

  event.recipes.custommachinery.custom_machine("namespace:machine_id", duration)
  
  //Add requirements here

})

Drop

• The filter param must be an array of items. Example : [Item.of("minecraft:diamond"), Item.of("minecraft:cobblestone")]. It represents a whitelist of items to search.

• The whitelist param must be a boolean, if set to false the filter will be a blacklist instead of a whitelist.

Function

Use one of these methods to add a function that must be processed by the machine to continue the recipe.

Note: This has nothing to do with MC functions (or commands), this requirement allow you to make your own code in JavaScript and pass it to be executed by the machine.

//Executed when the machine is idle and search a recipe to process.
//Returning success will allow the machine to process this recipe (if all other requirements allow it as well).
//Returning error will prevent the machine to process this recipe (the machine will keep searching for another valid recipe).
.requireFunctionToStart(ctx => {return Result.success()})

//Executed the first tick of the crafting process.
//Returning success will allow the machine to continue to process this recipe.
//Returning error will put the machine in error status and display the provided error message.
.requireFunctionOnStart(ctx => {return Result.success()})

//Executed each tick of the crafting process.
//Returning success will allow the machine to continue to process this recipe.
//Returning error will put the machine in error status and display the provided error message.
.requireFunctionEachTick(ctx => {return Result.success()})

//Executed the last tick of the crafting process.
//Returning success will allow the machine to continue to process this recipe.
//Returning error will put the machine in error status and display the provided error message.
.requireFunctionOnEnd(ctx => {return Result.success()})

• The passed function MUST return a Result.

• Valid results are : Result.success() and Result.error("Error message")

• Context has various methods for interacting with the machine, see it's wiki page

• The function can be delayed, put .delay(delay) directly after any .requireFunctionXXX() call to make the function be executed at the specified delay.

Example :

onEvent('recipes', event => {
	event.recipes.custommachinery.custom_machine("custommachinery:power_crusher", 200)
	.requireFunctionEachTick(ctx => {
		var remaining = ctx.machine.addItemToSlot("output1", Item.of("minecraft:diamond", 2), true);

		if(item.count == 0) {
                        ctx.machine.addItemToSlot("output1", Item.of("minecraft:diamond", 2), false);
			return Result.success();
                }
		return Result.error("Can't add 2 diamonds in output slot");
	})
})

Requirements special properties

Some requirements (almost all) have various properties that can change its behavior.

To set these properties you must call one or several of the methods below immediately after the desired requirement. The properties will only be applied on the latest added requirement when the method is called.

If the latest added requirement doesn't support the property an error will be logged and nothing will happen (the property will be ignored).

Chance

Use this method to add a chance property to the latest added requirement.

.chance(chance)

• The chance param must be a double between 0.0 and 1.0 included.

Supported requirements :

• Command

• Drop

• Durability

• Energy

• Energy Per Tick

• Fluid

• Fluid Per Tick

• Item

Delay

Use this method to set a delay for the requirement action.

The requirement will only execute its action after the specified delay.

.delay(delay)

• The delay param must be a double between 0.0 and 1.0 excluded. 0 represent the start of the recipe and 1 represent its end.

Supported requirements :

• Block

• Command

• Drop

• Function

Priority

Use the method below to set the priority of the recipe.

If this method is called several times only the latest will be used.

If this is called AFTER .jei() (no need to be immediatly after) this will act as the "jeiPriority" instead, defining the priority of the recipe to show in jei instead of the priority to be checked in the machine.

If no priority is set, the default value : 0 will be used.

.priority(priority)

• The priority param must be an integer value.

Jei

If the method below is called, all requirements added after that will be added to the jei property requirement list.

.jei()

This action cannot be inverted, you must add all your recipe requirements before calling it.

Requirements added after this method will only be displayed in jei but executed by the machine. Learn more here.

Examples :

Example 1

A 100 tick recipe that use 5mB of water, 5mB of any fluid with tag lava and 20FE per tick to create a stone.

onEvent('recipes', event => {

  event.recipes.custommachinery.custom_machine("custommachinery:stone_generator", 100)
  .requireFluid(Fluid.of("minecraft:water", 5))
  .requireFluidTag("#minecraft:lava", 5)
  .requireEnergyPerTick(20)
  .produceItem(Item.of("minecraft:stone", 1))
})

Example 2

A 200 tick recipe that use 1 item with tag stone and 20FE per tick to create 1 cobblestone, 1 gravel with 50% chance and 1 sand with 10% chance.

onEvent('recipes', event => {

  event.recipes.custommachinery.custom_machine("custommachinery:power_crusher", 200)
  .requireItemTag("#forge:stone", 1)
  .requireEnergyPerTick(20)
  .produceItem(Item.of("minecraft:cobblestone", 1))
  .produceItem(Item.of("minecraft:gravel", 1)).chance(0.5)
  .produceItem(Item.of("minecraft:sand", 1)).chance(0.1)
})
