This datapack adds realistic physics to items and blocks in Minecraft.

Information:

All objects have their own unique characteristics. For example, heavy blocks such as obsidian or stone have a large mass. They are hard to throw far, but they are very durable and difficult to break.

With light items, everything is the opposite: they easily bounce off surfaces and fly well, but break quickly. For example, glass will break after 2–3 hits, while stone tools can withstand about 6–8 hits.

Real-life aspects are also taken into account:

• Golden armor and tools are very light due to the material, so they break in just 2 hits.
• Wooden planks can float on water, but they cannot support the player’s weight.
• A barrel works like a buoy: it can stay afloat for a long time and can support the player’s weight.

Creating your own item with physics:

If you want to create an item with custom physics, use the following command:

/give @s minecraft:barrel[minecraft:custom_data={destructive:10,swim:5000,masse:12,hitbox:1}] 25

Parameters:

• destructive — how many hits the object can withstand before breaking.

• swim — how many ticks the object can stay afloat without sinking.

• masse — the mass of the object. The lower the value, the lighter the item and the farther it can be thrown. This parameter also affects buoyancy:

  • less than 9 — the object sinks;
  • 10 or higher — the object does not sink and can support entities on water.

  • hitbox — 1 or 0, enables or disables the object’s hitbox (mostly needed for blocks).
