Playing Win 10 Edition version 1.2 now, seed -1649128113
Looking for a Witch Hut so I can build a redstone farm, hopefully
But so far I haven't found any swamps in this world, at least none that I saw, so easy to go right past a biome when exploring
I did find 1 mushroom biome that I think is almost a swamp to the SW a ways from the spawn point but no other mushrooms and no discolored water areas that usually indicate a swamp, anyone have a decent tool for locating them, Just need to make my redstone farm and a gold farm and then I'm all good
According to this post, you can add 4294967296 to a (negative) Bedrock Edition seed to find the equivalent Java Edition seed, which you can then use in Amidst to find biomes, although there are slight differences in geography and none of the structures will match, including witch huts. I've successfully used this a couple times to get worlds that looked more or less the same in both Bedrock and Java, although I have had some failures that I couldn't explain.
Your seed translates into 2645839183. This shows a start spawn in plains with nearby taiga and forest. Does that sound right? If it is, it looks like there is a swamp to the southwest across the ocean and one due west, past the taiga.
Hmmm... a quick check in the game itself suggests that Amidst is correct for the immediate area, but in Bedrock, the swamp area at -512, 0, 512 is replaced with roofed forest. The second "swamp" I checked out was mixed plains and regular forest. Funny... the taiga and flower forest biomes appear to be in the correct spots... the recent changes to world gen (ravines) may have changed too much to keep them in sync.
Best suggestion now, if you don't have cheats on in this world and don't want them on, is to make a second world with the same seed but in creative mode and just fly around.
