Stack Massive (Achievements Friendly)

In vanilla Minecraft, many blocks and items can only stack up to 64 per slot, while others such as totems, beds, boats, buckets, or minecarts take up much more space than they should. With Stack Massive, those items can stay organized in a single visual stack, while the addon automatically keeps track of the real total amount.

How It Works

When you pick up compatible items, the addon automatically compacts them. The physical stack still respects Minecraft’s normal limit, usually 64, but the addon stores the remaining amount internally.

For example:

• If you have 64 planks and pick up 1 more, the stack will show x65.
• If you have 3,000 blocks, it may show something like x3k.
• For huge amounts, it can go up to x1m.
• When you use, place, consume, or drop items, the amount is deducted correctly.
• When the physical stack runs out, the addon refills it from the stored amount.

This makes survival gameplay more comfortable without filling your entire inventory with repeated stacks.

Compatible Items

Stack Massive works with normal stackable items and also supports several special items that Minecraft usually limits heavily.

Supported items include:

• Normal blocks.
• Common stackable items.
• Totems of Undying.
• Potions, separated by effect and type.
• Beds, separated by color.
• Boats, separated by wood type.
• Chest boats, separated by wood type.
• Minecarts and their variants.
• Empty and filled buckets.
• Armadillo scutes.

Different items remain separated. For example, a red bed will not merge with a blue bed, a Night Vision potion will not merge with a potion without effects, and an oak boat will not merge with a spruce boat.

Unsupported Items

To prevent bugs, item loss, or duplication, the addon does not compact items that should not be merged.

Unsupported items include:

• Swords.
• Tools.
• Armor.
• Bows.
• Crossbows.
• Tridents.
• Shields.
• Items with durability.
• Enchanted items.
• Custom items with their own name or lore.
• Spawn eggs.
• Other items that could lose important data.

This is done to protect your world and prevent unique items from being merged incorrectly.

How To Use

You do not need any menu, commands, or special items.

Just:

1. Install the .mcpack.
2. Activate the behavior pack in your world.
3. Enter the world and play normally.

The addon works automatically while you pick up, use, place, consume, drop, or move compatible items.

Important

Minecraft Bedrock does not allow addons to directly change the native inventory counter beyond the game’s normal stack limit. Because of that, Stack Massive uses an intelligent reserve system: it keeps a usable physical amount and stores the rest internally, while showing the real total on the item.
