Minecraft Physics mod guide

Minecraft has elementary and somewhat fictional physics. Most blocks can simply float in the air without falling; the particle effects when a block is mined are 2D, and the water is completely static and blocky in nature. Thankfully, the game is a sandbox, and the community has created a plethora of mods to alter almost everything about the game.

One of the most popular mods is simply called Physics mod. As the name clearly indicates, it completely enhances the physics of each block in the game, including liquids. Here is a guide on Minecraft's Physics mod.

Everything to know about the Physics mod for Minecraft

What does the Physics mod offer in Minecraft?

The Physics mod for Minecraft adds a whole bunch of physics-related features, like realistic particles after breaking a block and unique ragdoll physics for entities after they die.

When observed more closely, the Physics mod adds all kinds of real-life forces to the game, like gravitational force, applied force, frictional force, etc. These forces are clearly seen when a block is mined, and its particles move around and fall to the ground. If these particles still exist and players move through them, they will move away in a realistic manner to make way for the player.

Similarly, when a mob is killed, it does not jump and turn sideways like the vanilla animation. Rather, the mob will simply ragdoll and fall to the ground. Its limbs and other body parts might come apart while dying as well, which makes for a unique look.

Another unique feature the free version offers is gravity-affected mining. This means that if a player mines a block on the ceiling of a cave, several blocks above that particular block will also drop and fall. Unlike gravel or sand, these blocks will simply break and drop as items, but their particles will fall over the player, giving them a realistic gravitational feel.

The mod also offers realistic liquid physics. Liquids like lava and water will flow more naturally. Large lava lakes and water oceans will also have a more pronounced wave effect. The projectiles thrown or shot in Minecraft also get a new look and physics. Even the snow on cold biomes massively changes.

4. Download and install one of the modding APIs if you have not, and make sure that it is compatible with the 1.21.4 game version, which is the latest at the moment.
5. Copy and paste the downloaded Physics mod file into the 'mods' folder in Minecraft Java Edition's directory, which should be C:\Users\admin\AppData\Roaming\.minecraft.
6. Open the launcher and play the modded Minecraft version 1.21.4. The modded version should appear after you install the modding API.

How to tinker with Physics mod settings

Once the game opens, you won't notice any major changes until you enter a world and start mining or killing entities. Once you do, you will instantly see the new particle effect of the mined block or ragdoll of a dead entity.

If you want to tinker with the settings, all the Physics mod settings are available in the vanilla settings menu. The feature settings are neatly divided and are accompanied by a picture depicting exactly what that feature does in the game.

You can go into each setting and tweak the particle effect, the ragdoll effect, the liquid effect, and more.
