Note: As of June 2024, this mod requires Realistic Physics to be installed!

Description

Are you tired of the unrealistic building mechanics Minecraft has to offer? Perhaps you just want to wreak havoc and watch some buildings crumble? If so, this is probably the mod for you!

Realistic Block Physics is a realistic overhaul of Minecraft's building mechanics that will add a new sense of challenge and immersion into your worlds. Each block has been given its own unique physics definition that defines its mass, ability to support other blocks, fragility, and many other attributes. Exploring caves are also deemed more dangerous, as mining the wrong block could end up causing their ceilings to collapse!

Physics Engines

Multiple physics engines are also available, depending on whether you want a more realistic or casual experience.

Realistic: The most realistic experience (obviously).
Simple: A much more casual experience. Blocks will only fall if they are not connected to anything.
Legacy: The old physics engine used in versions prior to 1.12.2-2.0.0.

Key Features

Logical Construction Required

Blocks and structures will fall if they are not correctly supported (depending on the physics engine).

Mod Compatibility

Blocks from other mods are also supported (requires activation in the configuration file).

Cave Strengthening Algorithm

A new cave strengthening algorithm has been developed to help prevent large caves from collapsing in on themselves. However, bear in mind that cave-ins and landslides are still possible.

Performance

Performance has become a key priority to ensure this mod can function on a variety of systems, with configuration available.

Lots of Customisation

Highly customisable configuration files are provided so that you can tweak just about anything.

Override Vanilla Physics

This mod can also be used to alter or completely disable Vanilla falling block physics.

FAQs

Will you be porting this mod to other mod loaders?

Maybe. Unfortunately, I don't currently have the time to spend doing this while also maintaining the mod for Forge.

Where are the configuration files?

Within the "config" folder of your Minecraft installation directory, there will be another folder called "rbp" which houses all the configuration files of the mod. The file is automatically generated after loading the mod for the first time.

How do I change the physics engine?

Within the root configuration folder, there is another folder called "world_definitions". Each file in there allows you to specify the physics engine for each dimension.

How can I configure which blocks are affected by physics?

Within the root configuration folder, there is another folder called "block_definitions". Each file in there acts as a physics definition to apply to one or more blocks. The file names can be called whatever you want, as long as they are unique. You are free to modify and remove existing files, and also add additional files to customise the physics.

What Minecraft versions are you actively maintaining?

At the moment, updates to the mod will be supporting the following versions:

1.20.1-1.20.6
1.19.2-1.19.4
1.18.2
1.16.5
1.12.2
