Block Modifier is a utility for modifying and randomizing the physical, gameplay, and visual properties of any block in Minecraft.

This mod is experimental, and its future support is uncertain.

Warning!

Modifying fundamental game physics can lead to chunk corruption or unstable world generation.

• Always back up your world before making any block modifications, even if the change seems minor or insignificant. An incorrect parameter (such as setting air status or light emission incorrectly) can permanently corrupt your world save.
• Be cautious with settings that can cause player suffocation or trap entities inside solid blocks.

Key Features:

Examples of some of the possible changes in the block:

• Real-time Editing: Fine-tune block properties (including blocks from other mods) directly in-game via a graphical menu (default key is O).

• Chaos & Fun Mode: Instantly shuffle block properties globally using the randomizer to create a chaotic, challenging, or completely "cursed" world to play and have fun with your friends.

• Physics and Behavior Control: Modify friction (slipperiness), movement speed, jump height, blast resistance, mining time, touch damage, and experience drops upon block destruction.

• Rendering and Geometry Customization: Manage collision (passability), light emission, emissive textures in the dark, shadow opacity, and the ability to turn blocks into passable "ghost blocks" (air mode).

• Gravity Control: Enable falling behavior for standard solid blocks (similar to sand), as well as the ability to completely disable gravity for vanilla falling blocks (sand, gravel, anvils)**

• Configurable Randomizer: Randomize block properties globally with customizable limits and a flexible blacklist to protect critical blocks (bedrock, air, fluids) from accidental changes.

• Modded Block Support: Since the mod works directly with the game's block registry at runtime, you can customize and modify the properties of almost any block introduced by other installed mods.

• Multiplayer Synchronization: Automatically transmit and apply modified physics from the server to all connected players on the fly (utilizes GZIP packet compression to prevent network freezes), with server profile configuration restricted to server administrators.

• Profile Manager: Quickly save and load physics presets, integrate with singleplayer world save folders, and automatically restore vanilla parameters upon exiting the game.

Аnd much more!
