[echo lagoon]

first texture is overlay

let overlayItems = ['crushed', 'dust_impure', 'dust_pure', 'wire_fine']
    global.database.forEach(items => {
        items.itemsOptions.forEach(shapeItem => {
            let id = items.id == 'raw_material' ? 'raw' : items.id

            if (shapeItem.includes(overlayItems)) {
                let itemOverlay = event.create(`unify:${items.id}_${shapeItem}`)
                    .maxStackSize(64)
                    .color(0, items.color)
                    .texture('layer0', `unify:unify/${shapeItem}`)
                    .texture('layer1', `unify:unify/${shapeItem}_overlay`)

                return
            }

            let item = event.create(`unify:${id}_${shapeItem}`)
                .maxStackSize(64)
                .color(0, items.color)
                .texture(`unify:unify/${shapeItem}`)
        })
    })

global.database = [
    { id: 'copper', color: '#FF6400', hardness: 5, level: 'minecraft:needs_stone_tool', oresOptions: ['stone', 'deepslate'], itemsOptions: ['dust_impure'] },
]
