BorderBlock - See Your World in a New Light!

BorderBlock is a meticulously crafted resource pack that reinvents the visual style of Minecraft by adding clean, stylish borders to a vast array of blocks. Whether you're a builder, explorer, or redstone engineer, BorderBlock brings a new layer of clarity and artistic flair to your world, making every structure pop and every detail stand out.

🎯 Inspiration & Credits

This project was inspired by the excellent "Protect My Eyes" resource pack by 黑山大叔 (hsds), which introduces borders to certain blocks for visual comfort. While inspired by this concept, BorderBlock is a completely original work created from scratch by LiuJiale, featuring:

• A much wider coverage of blocks
• Unique border designs and styling
• Support for versions 1.6.1 to 1.21.10

We extend our gratitude to 黑山大叔 for the original idea!

✨ Features

🎨 Universal Visual Enhancement

BorderBlock is designed to be comprehensive. We've added borders to a massive selection of blocks, including but not limited to:

• All Stone Variants: Cobblestone, Stone Bricks, Andesite, Diorite, Granite, and more.
• Wood & Planks: Every type of wood and its plank variant gets a crisp border.
• Terracotta & Glazed Terracotta: The colorful patterns of terracotta are now neatly contained.
• Concrete & Wool: Perfect for pixel art and modern builds.
• Prismarine & Deepslate: Enhance your aquatic and deep dark constructions.
• Nether Blocks: Nether Bricks, Blackstone, and Basalt look more imposing than ever.
• End Stones: Give the End a more structured, alien feel.
• ...and hundreds more!

🛠️ Practical Benefits

It's not just about looks! The added borders provide tangible gameplay benefits:

• Builder's Best Friend: Easily distinguish between similar-looking blocks. Perfect for aligning complex patterns and ensuring your builds are pixel-perfect.
• Cave & Mine Navigator: Never get lost in a dark, monotonous cave again. The borders help define your surroundings, improving spatial awareness.
• Accessibility: For players who have difficulty with visual clutter or distinguishing colors, the clear outlines can make the game world much easier to parse.

🔧 Technical Excellence

• Seamless Integration: Borders are designed to tile perfectly, ensuring there are no visual glitches at chunk borders or in large, flat surfaces.
• Performance Friendly: As a pure resource pack, it requires no mods and has a negligible impact on your game's performance.
• Wide Version Support: Faithfully recreated and tested across a huge range of versions, from the classic 1.14 to the latest 1.21.10.

🖼️ Gallery

• A testament to the transformative power of clean lines. BorderBlock adds structure and depth to the entire landscape, unifying diverse materials under a single, elegant visual language.

• The harsh landscape of the Basalt Deltas feels even more structured and defined with borders on basalt and blackstone.

💡 Did You Know?

All the borders in this resource pack are artistically derived from the darkest pixels found within each block's original texture. This ensures a cohesive and authentic look that remains true to Minecraft's vanilla aesthetic.

🔧 Technical Implementation

For those interested in the technical side, here's the Python script that made this resource pack possible (Since the Python script mechanically extracts the darkest color from each texture for coloring, dual-toned blocks could appear visually unusual. To address this, we've implemented additional manual refinement to optimize border coloring for these specific blocks):

import os
import glob
from PIL import Image
import numpy as np

def get_darkest_pixel_in_block(block):
    """
    Find the darkest pixel in a 16x16 block (considering transparency)
    Returns the pixel's hexadecimal color code
    """
    # Convert block to numpy array
    block_array = np.array(block)
    
    # Only consider opaque or semi-transparent pixels (alpha > 0)
    opaque_pixels = block_array[block_array[:, :, 3] > 0]
    
    if len(opaque_pixels) == 0:
        return None  # Return None if no opaque pixels
    
    # Calculate brightness for each pixel (using weighted formula)
    brightness = opaque_pixels[:, 0] * 0.299 + opaque_pixels[:, 1] * 0.587 + opaque_pixels[:, 2] * 0.114
    
    # Find the darkest pixel
    darkest_idx = np.argmin(brightness)
    darkest_pixel = opaque_pixels[darkest_idx]
    
    # Convert to hexadecimal color code
    hex_color = '#{:02x}{:02x}{:02x}'.format(darkest_pixel[0], darkest_pixel[1], darkest_pixel[2])
