Code

All code below belongs in the startup folder.

const $BasicStorageCell = Java.loadClass("appeng.items.storage.BasicStorageCell")
const $StorageComponentItem = Java.loadClass("appeng.items.materials.StorageComponentItem")
const $AEItems = Java.loadClass("appeng.core.definitions.AEItems")
const $AEKeyType = Java.loadClass("appeng.api.stacks.AEKeyType")
const $Item = Java.loadClass("net.minecraft.world.item.Item");

const namespace = "meng:";

let AECellComponentItems = {
}

/**

 * @param {Number} byte max capacity in KB

 */
function regCellComponent(byte,maxItemTypeCount,AE2Energy,bytesPer){
    let cellComponentId = `${namespace}cell_component_${byte}k`
    let storageCellId = `${namespace}item_storage_cell_${byte}k`
    AECellComponentItems[byte] = {
        byte:byte,
        cellComponent: cellComponentId,
        storageCell:storageCellId,
        maxItemTypeCount:maxItemTypeCount,
        AE2Energy:AE2Energy,
        bytesPer:bytesPer
    }
}

regCellComponent(512,63,3.0,4096)
regCellComponent(1024,63,4.0,4096)
regCellComponent(2048,63,5.0,4096)
regCellComponent(4096,63,6.0,4096)
regCellComponent(8192,63,7.0,4096)

StartupEvents.registry("item", event => {
    for (const key in AECellComponentItems) {
        let aeValue = AECellComponentItems[key];
        event.createCustom(aeValue.cellComponent,
            ()=>new $StorageComponentItem($Item.Properties().stacksTo(1), aeValue.byte))
        event.createCustom(aeValue.storageCell,
            ()=>new $BasicStorageCell(
                $Item.Properties().stacksTo(1), 
                Item.of(aeValue.cellComponent), 
                $AEItems.ITEM_CELL_HOUSING, 
                aeValue.AE2Energy, 
                aeValue.byte, 
                aeValue.bytesPer, 
                aeValue.maxItemTypeCount, 
                $AEKeyType.items()
            )
        )
    }
})

The code above registers storage components and matching cells from 512k to 8192k.

In game, you can also use Shift + Right Click like vanilla to separate the component from its housing.

Localization and textures follow the normal item registration workflow.

How to Use the Code Above

The helper is already prepared for you. Call regCellComponent with your parameters, then restart the game.

regCellComponent(512,63,3.0,4096)

Just call it like shown above, restart the game, and it will load.
