⁉️How the mod works:

  • Press G to open the function menu, and press H to stop the currently active function. Both keybinds can be changed in the settings.
  • Fully customizable tick frequency (20 game ticks = 1 second)
  • Customizable number of blocks affected per game tick
  • Customizable radius, where a radius of 1 means 1 chunk - the chunk the player is currently standing in. If the radius is set to 2, a total of 9 chunks will be affected: the player's current chunk plus the 8 surrounding chunks. See the image below ⬇️
  • You can choose specific blocks for the mod to interact with. This includes absolutely anything that can be placed: blocks, torches, paintings, doors, saplings, and more.
  • Blocks from other mods are supported as well.
  • There are no limits on numerical values.
  • If FPS drops to 0, the active function will automatically stop after 10 seconds.
  • For optimization purposes, the mod skips block state checks.

❗️THE LIGHTING ISSUE CAN BE FIXED BY REJOINING THE WORLD❗️

📌 The mod adds 4 functions, each performing a different action:

⚙️ Delete

  • Allows you to choose how frequently blocks will be DELETED from the chunk. Blocks are deleted randomly.
  • Example: Every 1 game tick, 10 blocks will be deleted within a radius of 1 chunk
  • This means that 10 blocks will be DELETED in 1 chunk every tick, or 200 blocks will be DELETED in 1 chunk every second.
  • To DELETE random blocks, leave the block selection field empty.

⚙️ Replace

  • Allows you to choose how frequently blocks will be REPLACED within the chunk.
  • Example: Every 1 game tick, 10 blocks of minecraft:stone will be replaced within a radius of 1 chunk with minecraft:bedrock
  • This means that every tick, 10 random stone blocks will be REPLACED with 10 bedrock blocks in 1 chunk, or 200 stone blocks will be REPLACED with bedrock every second.
  • To make the REPLACEMENT completely random, leave the block selection fields empty.
  • REPLACEMENT also works with blocks from other mods.
  • You can REPLACE:
    • a specific block with a random block
    • a random block with a specific block
    • a random block with another random block
    • a specific block with another specific block

⚙️ Create

  • Allows you to choose how frequently blocks will be CREATED within the chunk.
  • Example: Every 1 game tick, 10 blocks of minecraft:bedrock will be created within a radius of 1 chunk
  • This means that 10 bedrock blocks will be CREATED in 1 chunk every tick, or 200 bedrock blocks will be CREATED in 1 chunk every second.
  • Blocks are CREATED from the bottom upward.
  • To CREATE random blocks, leave the block selection field empty.
  • You can also CREATE an entire chunk using only one type of block, such as dirt, sand, or even torches.
  • CREATION also works with blocks from other mods.

⚙️ Swap

  • Allows you to choose how frequently blocks within the chunk will SWAP PLACES with each other.
  • Example: Every 1 game tick, 10 blocks will swap places with each other within a radius of 1 chunk
  • This means that 10 random blocks will SWAP PLACES every tick in 1 chunk, or 200 random blocks will SWAP PLACES every second.
  • To make SWAPPING completely random, leave the block selection fields empty.
  • Blocks from other mods can also be SWAPPED.

⚠️ BEFORE EDITING YOUR MAIN WORLD, I HIGHLY RECOMMEND MAKING A BACKUP FIRST ⚠️

📌 Notes

As the mod develops (if it does, of course lol) the existing functions will be expanded, and NEW ones may possibly be added in the future!
