export const berryBlocks = [
    {
        //the berry block ID
        blockID: "gr_lab:bud",
        //the growth state ID
        stateID: "gr_lab:growth",
        //the max number in the growth state
        maxStage: 3,
        //the item ID
        itemID: "gr_lab:chapha",
        //the collect stages
        collectStages: [
            {
                //the stage for this collection
                stage: 3,
                //the amount of items to drop (max 64)
                itemAmountRange: {
                    min: 1,
                    max: 1
                },
                //after interacting, go to this stage
                toStage: 0,
                //the sound data
                sound: {
                    soundID: "block.sweet_berry_bush.pick",
                    volume: 1,
                    pitch: 1
                }
            }
        ],
        //the grow chance (numerator has to be less than the denominator, unless if you want the chance to be 100%)
        growChance: {
            numerator: 1,
            denominator: 2
        },
        //able to use bone meal on this block
        bonemealable: true
    }
];
