Make Block Replacements Happen Randomly

Percentage-Based Replacement

Instead of replacing every matching block, you can set a percentage chance so replacements happen randomly. This creates natural-looking variation in your world.

Steps

1. Open a JSON file in config/reliable_replacer or create a new one.

2. Add a replacement rule and include a percentage value that controls how often the swap occurs.

3. For example, set it to 50% to replace roughly half of the matching blocks, or 25% for a sparser distribution.

4. Save the file and type /reload.

5. The mod will now apply the replacement randomly based on your percentage.

Tips

• Percentage-based rules are excellent for creating natural ore distributions or scattered decorative blocks.
• Lower percentages (10-30%) create sparse, rare appearances.
• Higher percentages (70-90%) create dense coverage.
• Combine percentage rules with biome filters for region-specific randomness.
• Each block is evaluated independently, so results vary naturally across your world.
