Inspired by the Super Mario Bros. TAS | RT w/o loads: "1:52.284"
Seed: 4351321664971917955 | Version: 1.16.2
(Thanks @KaptainWutax for the nice libs c:)






Bedrock Cage Setup (minor issue below):

-A villager/village can create an Iron Golem, making you free with insane RNG.

(Possible Solution: Find another seed like this without a village in the loaded area)

Issue explained:
Iron golem can aggro mobs (including skeletons)
Skeletons can shoot creepers..
Creepers blow up destroying block..
Assuming the golem is lucky and never dies, they might reach my bed D:
Anyway new softlock video soon : )







Full Explanation:

BEFORE READING v v v
[Nobody verified my method yet, however I think this should be "Impossible" to escape in all events/conditions (hopefully xD)]
READ ABOVE ^ ^ ^

0) "Softlock" definition (for any game):

"A situation where a game remains apparently playable, but further progress in it is impossible (without cheating), typically due to a design flaw."

1) Right clicking beds (at any moment) will set your spawnpoint in 1.15+

2) Bed respawn rules:

-The spawnpoint can only be at the same height of the bed and directly next to it, else the game will try to spawn you on top of the bed. (The last possible respawn possibility)
-You have to leave 1 space of air above each bed block and at least 2 spaces of air for respawning next to the bed.

(IF all the above conditions are false, the bed will be obstructed and you will respawn at the starting spawn area of the world)

3) The bedrock layer under the world is made of different patterns and there are specific ones that make you stuck forever. (the softlock)

4) The main ideas used to ensure you stay forever in the softlock:

-Assuming perfect RNG, there's no possible in-game event that might free you from the softlock.
-No mobs that can add/remove blocks/entities/damage will be able to free you.
-Dying will respawn you in the softlock.
-As a direct consequence of the above, changing the difficulty has no effect. (Locking on Peaceful will also prevent you to die as well)
-No item can be collected once you are trapped in the softlock (except blocks/items that can't be used or can't let you out)

5) Now if we use the knowledge of the new bed respawning system and the specific patterns of the bedrock, we can get the player get in a state where:

- The only respawning point must be enclosed in this bedrock pattern.
(This means there's no glitchless way to escape the trap, although there's also no known glitches method as well)
- We set the bed close to the bedrock, ensuring that the only suitable place for the player respawn is the enclosed bedrock pattern.

[The pattern used in this video can be found near (X:-84, Z:-56) .. and not all worlds might have this specific one (depends on close structures), but there is at least "one" hidden in the 0.9 billion blocks area of the overworld]

6) To do this fast, we'll need a TNT / explosion (glitchless), which should explain why this seed was chosen C:

7) Then we simply let the player die as fast as possible and ...here we go... we are permanently trapped in the bedrock! (Unless you cheat)
