Random Placement
by mochensky
Random Placement changes what a block becomes when a player places it, swapping the chosen block for one drawn at random from the whole block pool.
What it does
Once the mod is installed, placing a block such as stone, dirt, planks or ore produces a random block instead, so a crafting table, a diamond block or an end portal frame can appear where the player expected the original. The swap happens on each placement attempt, which turns the usual placement step into a surprise. Because the replacement is drawn from the entire pool of blocks, the result cannot be predicted from the item in the hand.
The mod requires Fabric API and runs on Fabric only, with files for 1.16.5 – 1.21.11. Both the server and each player's client need the mod for placement to match. Its code and assets are released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, so the mod is not open source, though its source code and issue tracker are public.
Key features
Random block replacement
Each placement attempt is replaced with a completely random block taken from the full pool of blocks in the game.
Changed placement mechanic
The usual link between the item held and the block placed is removed, so building follows a new set of rules.
Unpredictable survival building
Survival gains a further layer of uncertainty, since the outcome of every placement is left to chance.
Vanilla progression still works
The mod does not stop the game from being completed, so a player can still beat the game with it installed.
