After 3 or so worlds pregen and explored widely. i've noticed a common theme here, continents/land mass/islands seem to repeat with very little difference over a given size. Was this intentional? Kinda takes away the new world out of just beating feet a few 1000 chunks.

BlackJar72 commented 5 years ago

No! That is definitely not intentional! And what really confuses me is that it doesn't seem to happen in my own world -- unless I broke something in an update.

BlackJar72 commented 5 years ago

I can confirm that the climate maps being saved are absolutely identical every time -- I don't know why ... ugghhhh, this is not what I'd planned to do today!

BlackJar72 commented 5 years ago

I have verified that it is generating completely different maps in each region as it should, but for some reason it's writing the same map to its save files everywhere. I have no idea why, I'm stumped and will probably need help from a real Java expert to figure it out. It's entirely likely this will have to be scrapped as a fail experiment. :(

EDIT: It's the same files, regardless of seed, which make no sense -- also, I don't see this bug at all in game, but based on what I'm finding must exist!

BlackJar72 commented 5 years ago

More testing shows this doesn't actually happen in game -- though something really, really weird is going on with the save files. Are you sure this wasn't made with some kind of map pregenerator that interfered? Or that another mod didn't interfere?

O13SC3N3 commented 5 years ago

Only Mods are

Biomes O Plenty 7.0.1.2424 Climatic Biomes 2.5.0

I've ran around and explored awhile and noticed the same beach line after a few hours exploring. Decided to dig deeper and had the same continent repeated almost exactly the same. Used a pregen same thing. Made 3 other maps and same thing. Granted the areas are more then large enough and easy to set up a border (4000 Chunks) I just didnt know if this was intentional or not. Its almost like each player could move to a 4000 or so chunk distant away and have their own same area almost.

BlackJar72 commented 5 years ago

No that shouldn't happen, and what has me confused is why its happen to you. My world so far is like this:

Anyway, I'm not sure what's going on -- I can't reproduce this here.

(I was also freaking out over the weirdness with my save files when it turns out my hash utility is broken somehow; the files are all different.)

It seems to repeat after 4000+ Chunks

BlackJar72 commented 5 years ago

4000 CHUNKS?! It should start a new continent every 4096 blocks. 4000 chunks should be 16 continents, that doesn't look like 16 continents. I also went ahead and did a quick check -- I used tp to see how things were 1,048,576 blocks (65536 chunks, 256 continents) out. Nope, I don't get the same maps, even there. You're not trolling are you?

O13SC3N3 commented 5 years ago

Not trolling, must be on my end. Ill experiment with it and see what else i come up with.

BlackJar72 commented 5 years ago

I'll ask if anyone else has seen anything like this.

BlackJar72 commented 5 years ago

I have found a world that does duplicate but not every continent (one duplicate directly next continent over). I don't know the period, however, it could be a problem with the math I use to generate random numbers for specific coordinates; it could be this mod has broken seeds.
