MC-8187 / 2x2 Surrounded Saplings Fix

This mod solves a long-standing Minecraft issue related to bug MC-8187. Now saplings that require 2x2 space for growth (spruce, jungle, and dark oak) can successfully grow into full trees even when completely surrounded by blocks on all four sides.

How It Works

The fix eliminates an error in the TreeFeature.getTopPosition function that caused the system to check a 3x3 area around the trunk instead of the required 2x2. This resulted in considering extra blocks that shouldn't affect the tree growth process.

Installation

To use the mod, you need to install Fabric or Quilt on Minecraft versions 1.16 and newer. After installing a compatible loader, simply add this mod to the mods folder.

Possible Consequences

After installing the mod, trees with 2x2 saplings may appear more frequently in the world than before. Also, in old builds where saplings were surrounded by blocks, trees may unexpectedly grow.

Mods that add 3x3 trees may work incorrectly if they rely on the standard system for checking valid growth space.

Interesting Details

• The mod was created for version 1.16.5 but is fully compatible with all versions from 1.16 to 1.20.1
• Development was done using the Segoe Script font
• Some users criticize this mod for its impact on compatibility
