A handful of logic functions in the mod can be changed using KubeJS.

Player Interface

The Player Interface allows you to wirelessly connect to your player inventory as if it were a block inventory.

It has a predicate that it uses to check if it's allowed to connect to a given player. By default, the predicate is

(Player, BlockEntity) -> Boolean = { _, _ -> true }

That is, it always allows connections. You can change the predicate using KubeJS to call this method:

const $PlayerInterfaceBE = Java.loadClass('dev.aaronhowser.mods.irregular_implements.block_entity.PlayerInterfaceBlockEntity')

$PlayerInterfaceBE.setPlayerPredicate((player, blockEntity) => player.level == blockEntity.level)

With that example, the Player Interface will only be able to connect to its owner if they are in the same dimension.

Bean Stalk Growth

The Magic Bean Stalk, by default, grows upwards constantly breaking through blocks until it reaches the build height, before placing a Bean Pod.

It does this using a predicate. When the predicate returns true, the current, topmost Bean Stalk block turns into a Bean Pod instead of growing another Bean Stalk above itself. The default predicate it uses is this:

		private fun defaultStrongIsDonePredicate(level: Level, pos: BlockPos): Boolean {
			// If it cannot grow above the current block without exceeding the build height, it's done
			if (pos.y + 1 >= level.maxBuildHeight) {
				return true
			}

			// If the block directly above it is indestructible, it cannot grow any farther
			val posAbove = pos.above()
			return level.getBlockState(posAbove).getDestroySpeed(level, posAbove) == -1.0f
		}

You can change this predicate using KubeJS by calling this method:

const $BeanStalkBlock = Java.loadClass('dev.aaronhowser.mods.irregular_implements.block.BeanStalkBlock')

$BeanStalkBlock.setMagicBeanStalkIsDoneGrowingPredicate((level, pos) => pos.y >= 100)

Divining Rod Colors

The Divining Rod can support any item with a tag starting with #c:ores/. However, only ores from vanilla and Mekanism have colors by default.

It does this using a map of Resource Location to RRGGBB color integer. You can add to this map using KubeJS and reflection:

const $DiviningRodItem = Java.loadClass('dev.aaronhowser.mods.irregular_implements.item.DiviningRodItem')
const $ResourceLocation = Java.loadClass('net.minecraft.resources.ResourceLocation')

$DiviningRodItem.COLORS_PER_TAG.put($ResourceLocation.fromNamespaceAndPath('c', 'ores/mythril'), 0xFF00FF)

This will give the Mythril Divining Rod the color 0xFF00FF, which is magenta.
