Is there a way to downgrade from 1.15.2 to 1.14.2 so that i can play my world because i have armor which doesnt have every protection and some have less than IV i tried and made a copy of my world but when i loaded my world the world generation reset. and everything i built is gone except for my inventory
The only way is to use a save converter; the save format was completely changed in 1.13 and it appears that the way the game now stores blocks, using a palette instead of actual IDs, and possibly how corrupted chunks are handled, makes it completely intolerant of invalid blocks (this page claims that newer versions are better at handling corrupted chunks - which just means throwing them away if even the slightest thing is amiss instead of attempting to load them anyway; however, I once loaded a 1.7 world in 1.5 just for fun and it actually did load the world mostly intact, aside from biomes like mesas and roofed forests missing blocks not present in 1.5 and even then the actual chunks were still intact, just missing hardened clay and dark oak trees. Even the 1.8 stone types will be retained (appearing as stone) from 1.8 to 1.7 since invalid metadata is ignored - the game doesn't even try to remove it so if you go back to 1.8 they will reappear. This is definitely not the case since 1.8 though since they use "block state" objects to represent blocks, where every combination of a block ID and metadata is treated as a separate block).
Either way, one would need to find/write a converter and I don't think one exists; it would also have to separately handle converting from 1.15 to 1.14 and 1.14 to 1.13 and possible even minor updates, like 1.15.2 to 1.15.1 (the data version for 1.15.2 is 2230 while 1.15.1 is 2227 and even snapshots and pre-releases differ; this value is stored in every chunk so the game can determine what version it was last saved in and only older data versions can be detected by a given game version. I'm not actually sure how important this is for minor updates (I haven't tested) but it is definitely an issue for major updates, at least when new blocks are added).

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
